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 <<<<<<< local35 - pronuncation guide :: a simple webpage where you type in a word and36 it returns a simpe, English sentence describing exactly how to37 pronounce the word. For people who don't want to learn IPA.38 =======39 - learning to teleport :: scifi idea, this is a story about a person40 who is struggling with his/her society's ideas about41 teleportation. It's considered a fundamental part of being a42 member of that society (after all, the difference between animals43 and humans is that humans are creatures of pure information while44 animals are burdened with base matter, "that's how you travel the45 stars, etc") Humans are born normally, grow up, and then46 eventually transcend via destructive upload. Analogies to jumping47 off a diving board into a pool (which I simply /could not do/ for48 a long time), etc.49 >>>>>>> other51 <<<<<<< local52 - touch vision :: inspired by GelSight, I want to reexamine cortex and53 see if I could implement touch as a very low range54 form of vision.55 =======56 - bitcoins for immigrants :: A common case with Mexican immigrants57 (illegal or not) is that they want to send money they've earned58 in the US back to their families in Mexico. They currently do this59 through things like Money Gram or Western Union, and they get60 fleeced in the process with fees. Bitcoin could greatly reduce61 the cost of sending money from America to Mexico, but I don't62 believe that it's currently used for that among Mexican63 immigrants currently due to lack of knowledge. I bet you could64 set up physical locations like those obnoxious Western Union huts65 in places like Texas, Arizona, etc, and greatly undercut66 them. Or, perhaps some educational seminars about bitcoin might67 be in order. There's some money to be made there because there is68 great demand, and it's a good thing to boot!69 >>>>>>> other71 <<<<<<< local72 =======73 - reverse eye-tracking :: A painting that is actually a digital screen74 with a camera. It records people's eye tracks permanently. It's75 "artistic" because paintings are normally these things that you76 look at without changing, but this one is changed the second you77 look at it, recording where /you/ looked forever for others to78 see. Make it be a painting of a woman and see the trolling as the79 breasts and groin area light up with interest from all the males80 passing by.82 - smart toilets :: Instead of using indirect measures like infrared83 detectors of the presence of a person, use computer84 vision to directly measure whether the toilet needs85 to be flushed. I think a lot of things will end up86 going this way as we get better computer vision.88 - validate chemopreservation :: chemopreservation is difficult to89 validate because it destroys the functionality of a brain, and90 brain simulation will take a long time to mature as a91 technology. However, one very powerful way to validate92 chemopreservation would be to have a person/animal learn93 something with high complexity such as a number or the solution94 to a maze, or a flashbulb memory. Then you preserve their brain95 chemically, slice it up, and read /that specific memory/ from the96 detailed brain scan. Much more difficult, but much more doable.98 - candy screw :: edible candy screw with candy nuts that you can screw99 as well.101 - better bibliography :: when writing a thesis or paper, have the102 bibliography not just be an opaque list of resources, but have it103 be a list of /summaries/ and /qualities/ that each paper has in104 the context of the paper being written. When examining a105 bibliography, I want to know if reading the papers in the106 bibliography are worth my time, and I also am probably also107 interested in exactly the things that are being discussed in the108 paper I'm reading. The bibliography is the perfect place to109 provide information about the referenced papers from the110 author's perspective. I will use this biographic form in my own111 thesis.113 - digital inter-library loan :: libraries at universities already do114 inter-library loans for books, so why not do the same for access115 to stupid paywalled digital papers? All the universities could116 allow access to articles for registered students to all the files117 available through any participating university. This could be118 achieved by sending requests through proxies at participating119 universities. Each university would decide who at the university120 can access the proxy network. Access to the proxy network could121 be made easy using something like http://libx.org/.123 - chess visual :: to show the vast size of the game trees considered124 by computers, show two people playing chess in a125 void. They are floating in space, and there is a126 simple chess board between them. Then, as they play,127 the game tree's they are considering are drawn128 behind him. The root of the tree starts centered in129 their heads or whatever they use to think, and the130 tree grows out from behind, never crossing the131 dividing plane between the two players. Each132 player's tree is a different color. As they grow,133 there are animations for pruning, etc. Eventually,134 they look like the hemispheres of a brain, wings,135 etc. A human's tree might occasionally have a long136 chain, while the computer tree would be more137 uniform. You could compare deep blue and a modern138 laptop. Use actual data when fighting two computers!140 - time verification :: some standard way to verify that some piece of141 data was recorded at a specific time. Might involve a time142 server, a key for each time period, something like that.144 - tamper proof gold bars :: [[http://www.tungsten-alloy.com/gold-plated-tungsten-alloy-bar.html][this site]] offers gold plated tungsten bars145 as "novelty" items. One reason to prefer coins is because they146 are much harder to counterfeit because there is less surface area147 to mass ratio. However, gold bars are still a great design148 because they can hold a lot of value in a small space. A gold bar149 could be given the same protections (and more) that gold coins150 have to offer by changing it into a "gold book", which would have151 hundreds of "pages" of gold bound together. This could be152 implemented with multiple steel rods going through the book which153 can be removed, or some more classier mechanism for holding the154 pages. The point is that the bar can be EASILY subdivided (and155 people would perform this test before buying), thus guaranteeing156 it's authenticity.158 - aurellem shirt :: I should make an aurellem star symbol tee-shirt.160 >>>>>>> other161 - high school science :: this is a lesson in scientific ethics. The162 goal is to calculate /g/, the local gravitational163 acceleration. The students are told that the textbook says it's164 /exactly/ 9.81 before they start the experiment. See how they165 doctor their results to get closer to the textbook value. It's166 neat because for any given school, /g/ is probably *not* exactly167 equal to 9.81, because that is just an average!169 - opencourseware subtitles :: there are ladies who type up lectures170 while they are being given. These recordings should be kept and171 given to OCW for subtitles. If the timestamps of keys are172 recorded, then it is easy to make subtitles.174 - screen locking timing :: you use your computer camera to see if you175 are sitting in front of the computer. If you are, then the screen176 will never lock. If you are, then the screen will lock with a177 30-40 second timeout. It's an extension of using inactivity to178 initiate the countdown, just with more information.180 - mirror toilet :: a toilet with a square basin made or mirror instead181 or porcelain. That way, you can see how good of a182 wipe job you have done / watch how your excretion183 system works.185 - test dummies :: why don't we clone anencephalic humans and use then to186 test /in vivo/ human organ systems and drugs? It187 would be ethical as long as there are women who are188 willing to host the clones, and it would be a189 tremendous resource for studying the human body. I190 see nothing wrong with it morally, since no one is191 suffering, and it stands to save many lives throughout192 more advanced technology.194 - X-ray telepresence :: given that a doctor is operating on a patient195 via telepresence, one cool things you can do is shine X-rays into196 the patient to view the insides during real time. If the system197 was coupled with a Bayesian model of the layout of the structure,198 and the x-rays were only fired whenever the uncertainty of the199 model reached a certain threshold, then the radiation damage200 and surgery risk could be minimized.202 - superfluid vascular system :: I wonder what would happen if you203 replaced the blood in a human with a superfluid. What would the204 physical dynamics be? Would the superfluid flow through the205 vasculature, or would it ignore it and travel through the cells,206 or something else entirely. Since superfluids need to be cold to207 retain their superfluidity, how would the dynamics change during208 perfusion of a superfluid, where the fluid gains and looses209 superfluidity as it goes deeper into the body and is cooled by210 superfluid from upstream. In summary there are two things to211 simulate 1.) replace all blood in human with superfluid212 instantly. 2.) perfuse superfluid into human.214 - projective guessing :: I think that we read and see things by215 making a really good guess about what we're expecting to see,216 and then searching for our guess in what we see. If it really217 doesn't match, then we start to make more guesses / analyze the218 image from first principles, but most stuff is projective219 guessing.221 - Intestinal flora maintenance :: why not inoculate babies at birth222 with "ideal" gut flora instead of whatever bullshit they223 naturally get, thus giving them optimal digestive/nutrient224 extraction capabilities. Might also be able to make their farts225 not stink for life, too.227 - server culture : mirrors :: make a distributed system where people228 can mirror the websites of people they like -- essentially cover229 the server costs of favored websites. This could make popular230 websites run at no cost. The system would require that the231 mirrored content be the same as the official source. Sort of like232 bit-torrent for websites.234 - map programming :: one problem with functional programming is that235 in order to remain functional, you have to pass up arguments up236 into each calling function to get the full range of behavior237 from the lower level functions. Normally people come to a238 compromise involving abstraction and sparing use of dynamic239 variables to configure runtime behavior. What would be the240 advantages of making a programming language where every function241 receives one argument, a map, which contains all the symbol242 bindings it would ever need? This map is passed on to all243 subordinate functions. This way, you could replace functions on244 the fly, and arrange for there to be sensible defaults,245 etc. Might cause more harm than good but is an interesting idea.247 - rest nest :: a small EEG device you would attach to your head when248 you go to sleep at night. ML algorithms would determine249 your particular sleep cycles. This would mostly be an250 alarm clock that you could give a time range, say251 7:00AM - 7:15AM, and it would wake you up during an252 ideal time corresponding to then end of one of your 90253 min sleep cycles. You would feel much more rested upon254 waking up, and would wake up faster. There might be255 some other uses for the EEG data as well.257 - image compression :: use a library like gimp or opencv to process an258 image to make it have less entropy, then store the reverse of259 those operations along with the compressed simpler image as a260 super-compressed image file (possibly accepting some261 losses). Trades file size for decompression time, and allows one262 to cheat by using information in gimp/opencv to compress the263 image.265 - fixed cryopreservation :: why not use a fixative to buy enough time266 to ramp up cryoprotectants to an acceptable level at room267 temperature? Then, the whole system can be rapidly cooled and268 vitrified. This method "severs the biological link" in that the269 fixatives are highly toxic, but current vitrification procedures270 do this anyway since there can be a lot of freezing damage.272 - dilated security camera :: a security camera that would capture273 full video footage of everything at 60fps but then decide to keep274 only every 1 frame every 5 seconds unless there's something275 "interesting" happening.277 - bitcoin wallet :: Part of "server culture", this would be something278 like "coin.your-domain.com" which would serve as279 your personal trusted access to your own bitcoins280 from anywhere.282 - libpay :: this would be a free library which would enable283 micro-donations to software projects and other projects,284 so that you could donate a penny to "emacs" and it would285 be automatically split up to every person who has ever286 contributed to emacs in proportion to the amount of287 community esteem, code quantity, bugs fixed, whatever the288 community decides. This might make it possible for289 programmers to live entirely off of free programming.291 - distributed graphics :: Browser based graphics-card accelerated292 distributed computing API.294 - pronouns :: use capital letters A-Z instead of pronouns. They solve295 pronoun referents and gender neutrality, are short to296 say, and you can encode useful information into the297 choice of letter. For example, instead of "Meetings298 shall be presided over by the president, unless she is299 absent." USE "Meetings shall be presided over by the300 president, unless P is absent." We already use this a301 little, since I and U are reserved for the subject and302 object respectively.304 - phone DSP :: software app that inserts an audio DSP between the305 input to a phone and the output. The DSP is delicious306 and configurable, and can allow men to make their307 voices deeper, etc. The app would allow you to hear308 your own voice as others hear it. Most people hate how309 their own voice sounds. The app would also allow one to310 immediately change the parameters of the DSP using good311 presets.313 - predestined body learning :: a good example of predestined learning314 might be the mirror neurons.316 - restaurant receipt :: use a carbon copy receipt instead of two stupid317 copies.319 - anti google glass :: glasses with mounted lasers and computer vision320 that targets the cameras in google glass and destroy them.322 - wearable towel :: towel with clasp, velcro, whatever, that allows323 one to wear the towel more securely than just324 wrapping it tightly and hoping for the best.326 - crossdressing :: Easiest way to disguise oneself as a woman is to327 wear a burka.329 - book-mode :: intelligent color highlighting for books and330 articles. It would disambiguate pronouns and involved331 references. For example, if "Rachael" as red, and "the332 blonde haired girl" refers to "Rachael", then "the333 blonde haired girl" would he colored red. Also, you334 could disambiguate multi part run-on sentences by335 highlighting each subcomponent. Maybe would also have336 applications to scientific reading.338 - Handheld light Rain measurement :: this would be a clear, teflon339 coated plastic disk with a camera underneath the disk. You would340 be able to hold the device out and it would measure the rate of341 accumulation of water droplets from fine mists and light rain by342 using computer vision to measure the diameters of the drops.344 - Big Brother Farming :: This would be a vision system that would345 individually monitor each plant and turn on water, etc to ensure346 maximum/uniform growth for each plant.348 - Discrete Faucet :: A faucet with discrete ticks instead of349 continuous.351 - Laser Circle :: take a glass microfiliment and shine a laser at one352 end at an oblique angle. It will make a perfect,353 large circle on the wall, converting a laser beam354 into a laser cone, preserving most of the energy of355 the laser.357 - Invisible Glass :: Take a container of liquid and embed a358 glass sculpture made out of glass that has exactly the same index359 of refraction and color of the liquid. Then the sculpture will be360 totally invisible in the container, and will only be revealed361 when the liquid is drained. The container might be a fancy362 wine/spirit bottle or an hourglass.364 - Caterpillar people :: A race of caterpillar like creatures gains365 intelligence after eons of predation by birds, etc. These366 caterpillar creatures still undergo metamorphosis into a large367 butterfly-like creature. The metamorphosis process turns the368 caterpillar's brain into mush and reforms it into a minimal,369 dumb, truly insect-like mind, completely destroying the person370 the caterpillar was. The society develops all sorts of customs and371 religious interpretations of the metamorphosis. It is viewed as372 good and natural by some since it is part of their life cycle and373 necessary to propagate the species, as only the butterflies can374 mate. Some think that the butterflies are still the same person375 because they have the same soul, even they no longer posses the376 memories or personality of the original caterpillar. Some see the377 butterfly form as the "true form" of the species, since the378 butterflies can fly, mate, and are beautiful. Many make a big379 deal out of the fact that 1-2% of the caterpillar's mind is380 actually preserved in the butterfly. Some see it as a terrible381 tragedy and argue that the caterpillars should try to stop the382 metamorphosis by technology. Practically, some very important383 members of society undergo hormone therapy and/or surgery to384 prevent metamorphosis so that they can live longer as themselves.386 This is a continuation of Marvin Minsky's ideas about pain being387 something that preserves our bodies while destroying our minds,388 something that is a remnant from our too harsh animal days that389 hasn't caught up to the fact that we have very complex brains390 now. It's a worst-case scenario about a maladaptive genetic391 legacy. Also, it's inspired by "There She Is!!!", which makes a392 compelling point about homosexuality by introducing a second393 gender characteristic (bunny/cat, male/female), which makes394 homophobia look very silly. Here, our own biological legacy of395 pain and death is made to look like the tragedy it is through the396 lens of the the caterpillar people.398 - relationships as a business :: [[http://thedailywtf.com/Articles/Up-or-Out-Solving-the-IT-Turnover-Crisis.aspx][Turnover-Crisis]] is an excellent talk399 about the "culture of quitting," which is about better business400 by letting people go instead of keeping them around past their401 "apex". Focuses on information transfer. Cool idea of an alumni402 network, which for relationships would be a group of satisfied403 ex-lovers, who would recommend new people your way, and who might404 consider coming to you again, refreshed from their time away with405 new stories/experiences. I should look for examples of this and406 how they worked out.408 - coffee with tea :: /rlm-tea/ contains 2% sugar, 10% cream, and 20%409 dylan coffee. /dylan coffee/ contains 5% sugar,410 20% cream, and 10% rlm-tea. Start your mornings411 with recursion!413 - psychic crystal :: in a science fiction story, this would be an414 object that is very easy to move physically but is extremely415 difficult to move with telekinesis.417 - http://betsofbitco.in/ :: what a great place for an AI/person to418 prove themselves as a good predictor. I wish this could be419 automated.421 - true reflection :: don't forget about that mirror in the student422 center!, it's two mirrors at right angles, like staring at a423 corner of a room. The light reflects so that it shows you what424 you actually look like, instead of your mirror image.426 - remote control wasp :: use computer to drive wings with remote427 power/logic.429 - encrypted email phone book :: public (distributed?) database of430 email->private-key pairs, to enable automatic encryption.432 - universal eye color :: every equivalent creature will see each433 others' eyes as black -- it's universal. Even if the creatures434 see in radio waves, and their eyes are 2m long pieces of jagged435 metal, when those creatures look at each other, they will see436 black, the absence of light and color (since it's being absorbed437 by the sensor array).439 - intelligent microwave :: it learns where the hot nodes of its fields440 are, and uses them to evenly heat any food item. It has an infrared441 camera or something to keep track of how hot the food is. That way,442 you don't get bowls where the edges are boiling, while the center is443 still frozen. Requires a little bit of intelligence/vision, since444 the exact pattern of heating totally depends on the exact shape of445 the food. Wouldn't need a carousel, and wouldn't need a timer,446 just a desired temperature. Could also detect ice, and automatically447 defrost the parts which are frozen. Might be able to work much448 faster since it can avoid overheating; might have problems with449 heating the insides of thick things, might need a weight sensor too.451 + Would be much cleaner than other microwaves, since food would452 "sputter" and splash liquid much less.454 + Throw in some SIFT+R processing to match previously cooked foods455 and learn the exact heating profiles for things that have been456 cooked before -- it can get faster the more it's used.458 - compression :: brain-aware image compression algorithm460 - Credit card proxy :: would be a company which works like paypal461 except for real world transactions463 - Flesh pillow :: a pillow like the arm or torso of a human, complete464 with simulated temperature, bones, and heartbeat.466 - super screw :: a screw which has only one or two threads and instead467 uses compression to fit into a hole (the whole shank468 of the screw is split into multiple pieces to469 accomplish this; the tip is a point, then the middle470 bulges out and gets compressed when screwed in.472 - light filter :: (like light tweezers) to mechanically separate473 fluids with different index of refraction475 - chalk eraser project :: maybe make a directional eraser, for easy476 release of chalk dust, like fur, and how it likes to rest in a477 certain direction.479 - silver socks :: socks laced with silver for the antimicrobial480 properties.482 - UROP :: magnet gear/metal teeth tape484 - Rod of Moses :: device to distill urine through evaporation and485 easily dispose of urea crystals for use in desert --486 produce drinkable water.488 - UROP :: Make the LED in line with the flow for the micro injector, so489 that it may transmit maximum flow. Motor that changes490 distance of internal magnet from windings depending on491 desired speed so as to obtain maximum power efficiency.493 - lottery scraper :: web scraper which monitors various lotteries,494 looking for "special" gimmick changes in the rules (like 4x495 winnings on Wednesdays) and computes expected value...497 - Memristiors novel design :: make an evolutionary algorithm to make498 old stuff using all four basic circuit elements.500 - Conductive concrete :: concrete that has embedded metal fibers so501 that it can conduct electricity.503 - little bitty melting pot :: might be useful for some types of504 manufacturing/3D printing -- how small can an induction melter be505 made, for example.507 - power strip/timer programmable combination :: meh509 - algorithms :: which learn what their inputs are and in what order,510 and can adapt to changing circumstances -- they511 remember previous arguments and adapt so as to respond512 to different connections.514 - true pure tones :: hear a true pure tone by direct stimulation of the515 nerves of the ear517 - mechanical analogue to the electrical op-amp :: would be an object518 with two levers -- you pull on one lever and the other moves the519 same way, no matter what's in the way or what it is driving. This520 analogy could be useful to teach op amps to people.522 - paper folding device :: make it convenient to fold lots of papers in523 various ways.525 - concrete epoxy :: epoxy with sand/ some other solid material.527 - light capacitor :: suspend some ball of material with a high index528 of refraction and shine light into it so it gets stuck -- would529 the light stay trapped forever? Could you build up unlimited530 quantities of light inside the sphere (which could then be531 released slowly by frustrated internal reflection?533 - movie screening :: Movies always are too long at first. One way to534 shorten them ``scientifically" is to record blink rate during the535 move and then remove / shorten the frames of the parts in which536 there are a lot of blinking (average this over multiple people)537 better yet, put it online and do it across thousands of people. I538 got this from youtube in which there is an episode of kill bill539 which is composed entirely of the parts in which people had their540 eyes closed. slogan: want to make a movie people can't take their541 eyes off of? Just take those parts out!543 - optimize an article :: capture reading of a scientific article via544 screen capture while people read it, then use it to make the545 article better. like the movie-pruning idea.547 - super reading program :: teaches people the ideal mental mask to548 apply during reading so as to read very fast.550 - explosive thermite epoxy putty :: one part would contain the rust,551 one part the aluminum.553 - reading comprehension :: use the above screen capture routine to554 make a quiz program that constructs questions about the content555 you seemed to gloss over while reading. could be easy if the pdf556 came with embedded questions. Dylan: automatically generate557 word-cloud about the parts you found most interesting; help558 others who read the same stuff by drawing attention to the559 interesting parts.561 - hard sword :: make a samurai sword, but use osmiridum instead of562 martensite for the cutting part; it should be a better563 sword.565 - close range wireless :: use the induction technology used to566 recharge electric toothbrushes with no metal links to send data567 without any metal at all!569 - reading :: is a form of synsethesia571 - DNA printer :: A machine which translates the text eg, "ACTGAC" into572 actual DNA574 - black generator :: ferro-fluid magnetic field suspended micro575 generator to make electricity577 - alcohol battery :: alcohol/fluid flow powered battery579 - folding razor blade sword ::581 - perfect pitch :: learn perfect pitch using another sense in582 combination (sight or touch)584 - kaleidoscope projector ::586 - razor blade de-sharpener :: for guilt free disposal588 - bricks :: filled with luminescent plant material590 - bio metallic structure :: metal grids with seeds inside, which grow591 together and form a durable biological matrix. The metal592 substrate delivers water. (maybe use plastic instead of metal?)593 Dylan: enrich plants with inorganic compounds; electrical594 interfaces in cellular plant matter => remote-controlled595 photosynthetic/bioluminescent structures.597 - conducting extracellular matrix :: to allow better control of598 organic systems and an enhanced nervous system.600 - cross-modal memory hashing :: a way to retrieve memories more601 robustly.603 - flossing thimble-guards :: (these actually exist)605 - rules + lattice learning :: integrate lattice learning with rules by606 generating hypothetical examples608 - wooden refrigerator :: to give food a better taste Dylan: like609 barrels for wine, or planks for salmon. Maybe just have "flavor610 planks" for your pre-existing fridge. Need to mitigate effect of611 temperature on volatility?613 - radioactive transmutation molecule by molecule :: create precious614 metals or something else economically advantageous.616 - crowd preservation :: inoculate food with tons of harmless617 bacteria so that there's no room for bad bacteria as a method of618 preservation620 - old school preservation :: Pasteur - style holding jar with siphon621 as a way to store liquids at room temperature indefinitely w/o622 refrigeration.624 - restaurant policy :: Throw rude people out of restaurant as a matter625 of course -- make ambiance much better.627 - clean windows :: make something that mixes soap with fire hydrant628 water (and reduces the pressure a bit) and use it629 to clean windows of buildings.631 - ocarina :: make an ocarina out of pure silver633 - fire pen :: pen which burns words on to the page, thus never needing634 any ink.
