Guys do you think it is possible to get energy out of typing on the keyboard?

Think about it.How many people use the computer everyday and type on it?the energy will be tremendous.

    Like xavier and scott lee said in their's not impossible and if you've picked up on this simple idea the probability that someone else has aswel which guarrantees more have toyed with it in moments of daydreaming.

    I would look into the nanotech industry.

    then maybe work backwards and cross reference the different energy capturing techniques we know of with the places you envision a possibility for energy capture. its tricky to get both halves of the equation together but you're on a great track. I wonder if our energy harnessing technology is advanced enough to work on the small scale of a keyboard. but it makes sense to me that a lot is possible on larger scales where our clunky existing technology is cheaper and adding bulk isn't a problem.

    Feb 29 2012: By "get energy out" I guess you mean do some additional work without doing anything in addition to pushing keys. Your fingers could be mechanically linked (via puppeteer strings and pulleys) to another device which repeats, or modifies your original motion. This only works if the linked operation requires no more energy than you supplied with your original typing effort. Hmmm. Rube Goldberg rest in peace.

    Feb 29 2012: They managed to make a phone charging bra that runs on the energy produced by friction up there.... So I'm pretty sure it's possible. Particularly if you consider how hard some people type

    I would like to see a smart phone that charges by the motion of moving around in my pocket, similar to a self winding watch. Though, I'm not sure how much energy could be harnessed this way. I have heard of a knee brace that can charge a laptop by absorbing the weight of a person as they walk.

    Feb 28 2012: I agree with what Xavier has to say, but at this stage in the game, there are much better sources of energy transfer to capture. It's a great thought though and maybe a future technology.

      Feb 28 2012: well sure, the amount of energy in each individual action is miniscule
      But, I did recently read an article on charging an ipod with sound vibrations, which I'm sure are far less in energy transfer.

      As you said, perhaps a future technology,
      but with the rate and speed that alot of people type, It has the potential to atleast charge a small device, perhaps more and ofcourse anything small x a great number = great energy production.

    If you put energy into something of this nature , you can get it out, atleast partially.
  • Feb 28 2012: This is an interesting topic. Exercise machines could also be a good source of energy?
