1 #+title: Big List O' Ideas2 #+author: Robert McIntyre3 #+email: rlm@mit.edu4 #+description: list of ideas from the last ~ 7 years5 #+keywords: aurellem ideas half-baked random6 #+SETUPFILE: ../../aurellem/org/setup.org7 #+INCLUDE: ../../aurellem/org/level-0.org8 #+babel: :mkdirp yes :noweb yes :exports both10 * Ideas12 This is a list of all the ideas I've had that I felt like writing down13 for the past ~ 7 years. Some of them could be practical inventions and14 are "just" waiting the that 95% perspiration to bring them to15 fruition, some are ideas for science fiction, and some are simple16 observations. Some are really only for my own personal notes and are17 not meant to be comprehensible. They are arranged roughly in reverse18 chronological order, with the most recent ideas at the top of the19 list. The ones at the bottom of the list are heavily influenced by my20 time at MIT.22 If you find some of these interesting and would like to collaborate on23 them with me or discuss them in more detail, I'd love to hear from24 you. You can email me at ideas@aurellem.org.26 If you want to use one of these ideas as your own and run with it,27 please feel free. I'd love to hear about it if you do.29 #+begin_quote30 There's no end to what a man can accomplish if he doesn't care about31 getting credit.32 #+end_quote34 - bitcoins for immigrants :: A common case with Mexican immigrants35 (illegal or not) is that they want to send money they've earned36 in the US back to their families in Mexico. They currently do this37 through things like Money Gram or Western Union, and they get38 fleeced in the process with fees. Bitcoin could greatly reduce39 the cost of sending money from America to Mexico, but I don't40 believe that it's currently used for that among Mexican41 immigrants currently due to lack of knowledge. I bet you could42 set up physical locations like those obnoxious Western Union huts43 in places like Texas, Arizona, etc, and greatly undercut44 them. Or, perhaps some educational seminars about bitcoin might45 be in order. There's some money to be made there because there is46 great demand, and it's a good thing to boot!48 - reverse eye-tracking :: A painting that is actually a digital screen49 with a camera. It records people's eye tracks permanently. It's50 "artistic" because paintings are normally these things that you51 look at without changing, but this one is changed the second you52 look at it, recording where /you/ looked forever for others to53 see. Make it be a painting of a woman and see the trolling as the54 breasts and groin area light up with interest from all the males55 passing by.57 - smart toilets :: Instead of using indirect measures like infrared58 detectors of the presence of a person, use computer59 vision to directly measure whether the toilet needs60 to be flushed. I think a lot of things will end up61 going this way as we get better computer vision.63 - validate chemopreservation :: chemopreservation is difficult to64 validate because it destroys the functionality of a brain, and65 brain simulation will take a long time to mature as a66 technology. However, one very powerful way to validate67 chemopreservation would be to have a person/animal learn68 something with high complexity such as a number or the solution69 to a maze, or a flashbulb memory. Then you preserve their brain70 chemically, slice it up, and read /that specific memory/ from the71 detailed brain scan. Much more difficult, but much more doable.73 - candy screw :: edible candy screw with candy nuts that you can screw74 as well.76 - better bibliography :: when writing a thesis or paper, have the77 bibliography not just be an opaque list of resources, but have it78 be a list of /summaries/ and /qualities/ that each paper has in79 the context of the paper being written. When examining a80 bibliography, I want to know if reading the papers in the81 bibliography are worth my time, and I also am probably also82 interested in exactly the things that are being discussed in the83 paper I'm reading. The bibliography is the perfect place to84 provide information about the referenced papers from the85 author's perspective. I will use this biographic form in my own86 thesis.88 - digital inter-library loan :: libraries at universities already do89 inter-library loans for books, so why not do the same for access90 to stupid paywalled digital papers? All the universities could91 allow access to articles for registered students to all the files92 available through any participating university. This could be93 achieved by sending requests through proxies at participating94 universities. Each university would decide who at the university95 can access the proxy network. Access to the proxy network could96 be made easy using something like http://libx.org/.98 - chess visual :: to show the vast size of the game trees considered99 by computers, show two people playing chess in a100 void. They are floating in space, and there is a101 simple chess board between them. Then, as they play,102 the game tree's they are considering are drawn103 behind him. The root of the tree starts centered in104 their heads or whatever they use to think, and the105 tree grows out from behind, never crossing the106 dividing plane between the two players. Each107 player's tree is a different color. As they grow,108 there are animations for pruning, etc. Eventually,109 they look like the hemispheres of a brain, wings,110 etc. A human's tree might occasionally have a long111 chain, while the computer tree would be more112 uniform. You could compare deep blue and a modern113 laptop. Use actual data when fighting two computers!115 - time verification :: some standard way to verify that some piece of116 data was recorded at a specific time. Might involve a time117 server, a key for each time period, something like that.119 - tamper proof gold bars :: [[http://www.tungsten-alloy.com/gold-plated-tungsten-alloy-bar.html][this site]] offers gold plated tungsten bars120 as "novelty" items. One reason to prefer coins is because they121 are much harder to counterfeit because there is less surface area122 to mass ratio. However, gold bars are still a great design123 because they can hold a lot of value in a small space. A gold bar124 could be given the same protections (and more) that gold coins125 have to offer by changing it into a "gold book", which would have126 hundreds of "pages" of gold bound together. This could be127 implemented with multiple steel rods going through the book which128 can be removed, or some more classier mechanism for holding the129 pages. The point is that the bar can be EASILY subdivided (and130 people would perform this test before buying), thus guaranteeing131 it's authenticity.133 - aurellem shirt :: I should make an aurellem star symbol tee-shirt.135 - high school science :: this is a lesson in scientific ethics. The136 goal is to calculate /g/, the local gravitational137 acceleration. The students are told that the textbook says it's138 /exactly/ 9.81 before they start the experiment. See how they139 doctor their results to get closer to the textbook value. It's140 neat because for any given school, /g/ is probably *not* exactly141 equal to 9.81, because that is just an average!143 - opencourseware subtitles :: there are ladies who type up lectures144 while they are being given. These recordings should be kept and145 given to OCW for subtitles. If the timestamps of keys are146 recorded, then it is easy to make subtitles.148 - screen locking timing :: you use your computer camera to see if you149 are sitting in front of the computer. If you are, then the screen150 will never lock. If you are, then the screen will lock with a151 30-40 second timeout. It's an extension of using inactivity to152 initiate the countdown, just with more information.154 - mirror toilet :: a toilet with a square basin made or mirror instead155 or porcelain. That way, you can see how good of a156 wipe job you have done / watch how your excretion157 system works.159 - test dummies :: why don't we clone anencephalic humans and use then to160 test /in vivo/ human organ systems and drugs? It161 would be ethical as long as there are women who are162 willing to host the clones, and it would be a163 tremendous resource for studying the human body. I164 see nothing wrong with it morally, since no one is165 suffering, and it stands to save many lives throughout166 more advanced technology.168 - X-ray telepresence :: given that a doctor is operating on a patient169 via telepresence, one cool things you can do is shine X-rays into170 the patient to view the insides during real time. If the system171 was coupled with a Bayesian model of the layout of the structure,172 and the x-rays were only fired whenever the uncertainty of the173 model reached a certain threshold, then the radiation damage174 and surgery risk could be minimized.176 - superfluid vascular system :: I wonder what would happen if you177 replaced the blood in a human with a superfluid. What would the178 physical dynamics be? Would the superfluid flow through the179 vasculature, or would it ignore it and travel through the cells,180 or something else entirely. Since superfluids need to be cold to181 retain their superfluidity, how would the dynamics change during182 perfusion of a superfluid, where the fluid gains and looses183 superfluidity as it goes deeper into the body and is cooled by184 superfluid from upstream. In summary there are two things to185 simulate 1.) replace all blood in human with superfluid186 instantly. 2.) perfuse superfluid into human.188 - projective guessing :: I think that we read and see things by189 making a really good guess about what we're expecting to see,190 and then searching for our guess in what we see. If it really191 doesn't match, then we start to make more guesses / analyze the192 image from first principles, but most stuff is projective193 guessing.195 - Intestinal flora maintenance :: why not inoculate babies at birth196 with "ideal" gut flora instead of whatever bullshit they197 naturally get, thus giving them optimal digestive/nutrient198 extraction capabilities. Might also be able to make their farts199 not stink for life, too.201 - server culture : mirrors :: make a distributed system where people202 can mirror the websites of people they like -- essentially cover203 the server costs of favored websites. This could make popular204 websites run at no cost. The system would require that the205 mirrored content be the same as the official source. Sort of like206 bit-torrent for websites.208 - map programming :: one problem with functional programming is that209 in order to remain functional, you have to pass up arguments up210 into each calling function to get the full range of behavior211 from the lower level functions. Normally people come to a212 compromise involving abstraction and sparing use of dynamic213 variables to configure runtime behavior. What would be the214 advantages of making a programming language where every function215 receives one argument, a map, which contains all the symbol216 bindings it would ever need? This map is passed on to all217 subordinate functions. This way, you could replace functions on218 the fly, and arrange for there to be sensible defaults,219 etc. Might cause more harm than good but is an interesting idea.221 - rest nest :: a small EEG device you would attach to your head when222 you go to sleep at night. ML algorithms would determine223 your particular sleep cycles. This would mostly be an224 alarm clock that you could give a time range, say225 7:00AM - 7:15AM, and it would wake you up during an226 ideal time corresponding to then end of one of your 90227 min sleep cycles. You would feel much more rested upon228 waking up, and would wake up faster. There might be229 some other uses for the EEG data as well.231 - image compression :: use a library like gimp or opencv to process an232 image to make it have less entropy, then store the reverse of233 those operations along with the compressed simpler image as a234 super-compressed image file (possibly accepting some235 losses). Trades file size for decompression time, and allows one236 to cheat by using information in gimp/opencv to compress the237 image.239 - fixed cryopreservation :: why not use a fixative to buy enough time240 to ramp up cryoprotectants to an acceptable level at room241 temperature? Then, the whole system can be rapidly cooled and242 vitrified. This method "severs the biological link" in that the243 fixatives are highly toxic, but current vitrification procedures244 do this anyway since there can be a lot of freezing damage.246 - dilated security camera :: a security camera that would capture247 full video footage of everything at 60fps but then decide to keep248 only every 1 frame every 5 seconds unless there's something249 "interesting" happening.251 - bitcoin wallet :: Part of "server culture", this would be something252 like "coin.your-domain.com" which would serve as253 your personal trusted access to your own bitcoins254 from anywhere.256 - libpay :: this would be a free library which would enable257 micro-donations to software projects and other projects,258 so that you could donate a penny to "emacs" and it would259 be automatically split up to every person who has ever260 contributed to emacs in proportion to the amount of261 community esteem, code quantity, bugs fixed, whatever the262 community decides. This might make it possible for263 programmers to live entirely off of free programming.265 - distributed graphics :: Browser based graphics-card accelerated266 distributed computing API.268 - pronouns :: use capital letters A-Z instead of pronouns. They solve269 pronoun referents and gender neutrality, are short to270 say, and you can encode useful information into the271 choice of letter. For example, instead of "Meetings272 shall be presided over by the president, unless she is273 absent." USE "Meetings shall be presided over by the274 president, unless P is absent." We already use this a275 little, since I and U are reserved for the subject and276 object respectively.278 - phone DSP :: software app that inserts an audio DSP between the279 input to a phone and the output. The DSP is delicious280 and configurable, and can allow men to make their281 voices deeper, etc. The app would allow you to hear282 your own voice as others hear it. Most people hate how283 their own voice sounds. The app would also allow one to284 immediately change the parameters of the DSP using good285 presets.287 - predestined body learning :: a good example of predestined learning288 might be the mirror neurons.290 - restaurant receipt :: use a carbon copy receipt instead of two stupid291 copies.293 - anti google glass :: glasses with mounted lasers and computer vision294 that targets the cameras in google glass and destroy them.296 - wearable towel :: towel with clasp, velcro, whatever, that allows297 one to wear the towel more securely than just298 wrapping it tightly and hoping for the best.300 - crossdressing :: Easiest way to disguise oneself as a woman is to301 wear a burka.303 - book-mode :: intelligent color highlighting for books and304 articles. It would disambiguate pronouns and involved305 references. For example, if "Rachael" as red, and "the306 blonde haired girl" refers to "Rachael", then "the307 blonde haired girl" would he colored red. Also, you308 could disambiguate multi part run-on sentences by309 highlighting each subcomponent. Maybe would also have310 applications to scientific reading.312 - Handheld light Rain measurement :: this would be a clear, teflon313 coated plastic disk with a camera underneath the disk. You would314 be able to hold the device out and it would measure the rate of315 accumulation of water droplets from fine mists and light rain by316 using computer vision to measure the diameters of the drops.318 - Big Brother Farming :: This would be a vision system that would319 individually monitor each plant and turn on water, etc to ensure320 maximum/uniform growth for each plant.322 - Discrete Faucet :: A faucet with discrete ticks instead of323 continuous.325 - Laser Circle :: take a glass microfiliment and shine a laser at one326 end at an oblique angle. It will make a perfect,327 large circle on the wall, converting a laser beam328 into a laser cone, preserving most of the energy of329 the laser.331 - Invisible Glass :: Take a container of liquid and embed a332 glass sculpture made out of glass that has exactly the same index333 of refraction and color of the liquid. Then the sculpture will be334 totally invisible in the container, and will only be revealed335 when the liquid is drained. The container might be a fancy336 wine/spirit bottle or an hourglass.338 - Caterpillar people :: A race of caterpillar like creatures gains339 intelligence after eons of predation by birds, etc. These340 caterpillar creatures still undergo metamorphosis into a large341 butterfly-like creature. The metamorphosis process turns the342 caterpillar's brain into mush and reforms it into a minimal,343 dumb, truly insect-like mind, completely destroying the person344 the caterpillar was. The society develops all sorts of customs and345 religious interpretations of the metamorphosis. It is viewed as346 good and natural by some since it is part of their life cycle and347 necessary to propagate the species, as only the butterflies can348 mate. Some think that the butterflies are still the same person349 because they have the same soul, even they no longer posses the350 memories or personality of the original caterpillar. Some see the351 butterfly form as the "true form" of the species, since the352 butterflies can fly, mate, and are beautiful. Many make a big353 deal out of the fact that 1-2% of the caterpillar's mind is354 actually preserved in the butterfly. Some see it as a terrible355 tragedy and argue that the caterpillars should try to stop the356 metamorphosis by technology. Practically, some very important357 members of society undergo hormone therapy and/or surgery to358 prevent metamorphosis so that they can live longer as themselves.360 This is a continuation of Marvin Minsky's ideas about pain being361 something that preserves our bodies while destroying our minds,362 something that is a remnant from our too harsh animal days that363 hasn't caught up to the fact that we have very complex brains364 now. It's a worst-case scenario about a maladaptive genetic365 legacy. Also, it's inspired by "There She Is!!!", which makes a366 compelling point about homosexuality by introducing a second367 gender characteristic (bunny/cat, male/female), which makes368 homophobia look very silly. Here, our own biological legacy of369 pain and death is made to look like the tragedy it is through the370 lens of the the caterpillar people.372 - relationships as a business :: [[http://thedailywtf.com/Articles/Up-or-Out-Solving-the-IT-Turnover-Crisis.aspx][Turnover-Crisis]] is an excellent talk373 about the "culture of quitting," which is about better business374 by letting people go instead of keeping them around past their375 "apex". Focuses on information transfer. Cool idea of an alumni376 network, which for relationships would be a group of satisfied377 ex-lovers, who would recommend new people your way, and who might378 consider coming to you again, refreshed from their time away with379 new stories/experiences. I should look for examples of this and380 how they worked out.382 - coffee with tea :: /rlm-tea/ contains 2% sugar, 10% cream, and 20%383 dylan coffee. /dylan coffee/ contains 5% sugar,384 20% cream, and 10% rlm-tea. Start your mornings385 with recursion!387 - psychic crystal :: in a science fiction story, this would be an388 object that is very easy to move physically but is extremely389 difficult to move with telekinesis.391 - http://betsofbitco.in/ :: what a great place for an AI/person to392 prove themselves as a good predictor. I wish this could be393 automated.395 - true reflection :: don't forget about that mirror in the student396 center!, it's two mirrors at right angles, like staring at a397 corner of a room. The light reflects so that it shows you what398 you actually look like, instead of your mirror image.400 - remote control wasp :: use computer to drive wings with remote401 power/logic.403 - encrypted email phone book :: public (distributed?) database of404 email->private-key pairs, to enable automatic encryption.406 - universal eye color :: every equivalent creature will see each407 others' eyes as black -- it's universal. Even if the creatures408 see in radio waves, and their eyes are 2m long pieces of jagged409 metal, when those creatures look at each other, they will see410 black, the absence of light and color (since it's being absorbed411 by the sensor array).413 - intelligent microwave :: it learns where the hot nodes of its fields414 are, and uses them to evenly heat any food item. It has an infared415 camera or something to keep track of how hot the food is. That way,416 you don't get bowls where the edges are boiling, while the center is417 still frozen. Requires a little bit of intelligence/vision, since418 the exact pattern of heating totally depends on the exact shape of419 the food. Wouldn't need a carousel, and wouldn't need a timer,420 just a desired temperature. Could also detect ice, and automatically421 defrost the parts which are frozen. Might be able to work much422 faster since it can avoid overheating; might have problems with423 heating the insides of thick things, might need a weight sensor too.425 + Would be much cleaner than other microwaves, since food would426 "sputter" and splash liquid much less.428 + Throw in some SIFT+R processing to match previously cooked foods429 and learn the exact heating profiles for things that have been430 cooked before -- it can get faster the more it's used.432 - compression :: brain-aware image compression algorithm434 - Credit card proxy :: would be a company which works like paypal435 except for real world transactions437 - Flesh pillow :: a pillow like the arm or torso of a human, complete438 with simulated temperature, bones, and heartbeat.440 - super screw :: a screw which has only one or two threads and instead441 uses compression to fit into a hole (the whole shank442 of the screw is split into multiple pieces to443 accomplish this; the tip is a point, then the middle444 bulges out and gets compressed when screwed in.446 - light filter :: (like light tweezers) to mechanically separate447 fluids with different index of refraction449 - chalk eraser project :: maybe make a directional eraser, for easy450 release of chalk dust, like fur, and how it likes to rest in a451 certain direction.453 - silver socks :: socks laced with silver for the antimicrobial454 properties.456 - UROP :: magnet gear/metal teeth tape458 - Rod of Moses :: device to distill urine through evaporation and459 easily dispose of urea crystals for use in desert --460 produce drinkable water.462 - UROP :: Make the LED in line with the flow for the micro injector, so463 that it may transmit maximum flow. Motor that changes464 distance of internal magnet from windings depending on465 desired speed so as to obtain maximum power efficiency.467 - lottery scraper :: web scraper which monitors various lotteries,468 looking for "special" gimmick changes in the rules (like 4x469 winnings on Wednesdays) and computes expected value...471 - Memristiors novel design :: make an evolutionary algorithm to make472 old stuff using all four basic circuit elements.474 - Conductive concrete :: concrete that has embedded metal fibers so475 that it can conduct electricity.477 - little bitty melting pot :: might be useful for some types of478 manufacturing/3D printing -- how small can an induction melter be479 made, for example.481 - power strip/timer programmable combination :: meh483 - algorithms :: which learn what their inputs are and in what order,484 and can adapt to changing circumstances -- they485 remember previous arguments and adapt so as to respond486 to different connections.488 - true pure tones :: hear a true pure tone by direct stimulation of the489 nerves of the ear491 - mechanical analogue to the electrical op-amp :: would be an object492 with two levers -- you pull on one lever and the other moves the493 same way, no matter what's in the way or what it is driving. This494 analogy could be useful to teach op amps to people.496 - paper folding device :: make it convenient to fold lots of papers in497 various ways.499 - concrete epoxy :: epoxy with sand/ some other solid material.501 - light capacitor :: suspend some ball of material with a high index502 of refraction and shine light into it so it gets stuck -- would503 the light stay trapped forever? Could you build up unlimited504 quantities of light inside the sphere (which could then be505 released slowly by frustrated internal reflection?507 - movie screening :: Movies always are too long at first. One way to508 shorten them ``scientifically" is to record blink rate during the509 move and then remove / shorten the frames of the parts in which510 there are a lot of blinking (average this over multiple people)511 better yet, put it online and do it across thousands of people. I512 got this from youtube in which there is an episode of kill bill513 which is composed entirely of the parts in which people had their514 eyes closed. slogan: want to make a movie people can't take their515 eyes off of? Just take those parts out!517 - optimize an article :: capture reading of a scientific article via518 screen capture while people read it, then use it to make the519 article better. like the movie-pruning idea.521 - super reading program :: teaches people the ideal mental mask to522 apply during reading so as to read very fast.524 - explosive thermite epoxy putty :: one part would contain the rust,525 one part the aluminum.527 - reading comprehension :: use the above screen capture routine to528 make a quiz program that constructs questions about the content529 you seemed to gloss over while reading. could be easy if the pdf530 came with embedded questions. Dylan: automatically generate531 word-cloud about the parts you found most interesting; help532 others who read the same stuff by drawing attention to the533 interesting parts.535 - hard sword :: make a samurai sword, but use osmiridum instead of536 martensite for the cutting part; it should be a better537 sword.539 - close range wireless :: use the induction technology used to540 recharge electric toothbrushes with no metal links to send data541 without any metal at all!543 - reading :: is a form of synsethesia545 - DNA printer :: A machine which translates the text eg, "ACTGAC" into546 actual DNA548 - black generator :: ferro-fluid magnetic field suspended micro549 generator to make electricity551 - alcohol battery :: alcohol/fluid flow powered battery553 - folding razor blade sword ::555 - perfect pitch :: learn perfect pitch using another sense in556 combination (sight or touch)558 - kaleidoscope projector ::560 - razor blade de-sharpener :: for guilt free disposal562 - bricks :: filled with luminescent plant material564 - bio metallic structure :: metal grids with seeds inside, which grow565 together and form a durable biological matrix. The metal566 substrate delivers water. (maybe use plastic instead of metal?)567 Dylan: enrich plants with inorganic compounds; electrical568 interfaces in cellular plant matter => remote-controlled569 photosynthetic/bioluminescent structures.571 - conducting extracellular matrix :: to allow better control of572 organic systems and an enhanced nervous system.574 - cross-modal memory hashing :: a way to retrieve memories more575 robustly.577 - flossing thimble-guards :: (these actually exist)579 - rules + lattice learning :: integrate lattice learning with rules by580 generating hypothetical examples582 - wooden refrigerator :: to give food a better taste Dylan: like583 barrels for wine, or planks for salmon. Maybe just have "flavor584 planks" for your pre-existing fridge. Need to mitigate effect of585 temperature on volatility?587 - radioactive transmutation molecule by molecule :: create precious588 metals or something else economically advantageous.590 - crowd preservation :: inoculate food with tons of harmless591 bacteria so that there's no room for bad bacteria as a method of592 preservation594 - old school preservation :: Pasteur - style holding jar with siphon595 as a way to store liquids at room temperature indefinitely w/o596 refrigeration.598 - restaurant policy :: Throw rude people out of restaurant as a matter599 of course -- make ambiance much better.601 - clean windows :: make something that mixes soap with fire hydrant602 water (and reduces the pressure a bit) and use it603 to clean windows of buildings.605 - ocarina :: make an ocarina out of pure silver607 - fire pen :: pen which burns words on to the page, thus never needing608 any ink. Is there a way to make it runnable from the609 human's energy?611 - website to design your own soda :: and label, and have it mailed to612 you / sell it from your own online store.614 - solar panels :: that float on the ocean616 - handcuffs with more than two cuffs (3?) :: great for daisy chaining617 people, binding them to environment, etc.619 - vector based SOUND files :: like the pictures but with SOUND. codify620 sound in a language with enough symbols so that it can describe621 everything and encode it in that. would be like going from speech622 to text or smtg. Could also store sound as an image of the623 wavefront encoded as a vector image.625 - Mouse :: with a horizontal scroll wheel in addition to the vertical626 scroll wheel628 - logic maintenance system for big institutions :: to make sure the629 things they are thinking about doing are not retarded631 - http://www.regulations.gov/ :: cool site633 - genetically engineered glowing fruit :: sell seeds?635 - memory slide :: IF memories are encoded using particular sensory636 impressions, what happens if the sensory organ637 itself changes? those memories would become638 inaccessible. maybe this is why we can't remember639 much from our childhoods. also, could this happen640 throughout life as well? Could S remember stuff from641 his childhood?643 - make a completely indestructible phone :: no moving parts or display644 you should be able to slam it around all you want, and it will645 just work. brutally simple. aerogel around the battery, minimal646 interface - never gets too hot, and can be dropped into water. no647 holes -- uses field effects for everything from the buttons to648 inductive charging and data transfer.650 - midi to ocarina "tabs" program :: (online website? buy ocarinas from651 it too)653 - 3d printing with sound pulses (or just patterns) :: like the 8.03654 lecture656 - lighter flint on spring :: make hot, throw it at something, and it657 makes sparkles!659 - nuclear energy :: Rebranding New+Clear Energy with informational660 campaign and public debate forum to enforce its661 transparent and open nature.
