If, for some reason, you do want a dedicated flashlight in your life, a 15 year-old genius, Ann Makosinski from Victoria, B.C. has developed a new, innovative version of the flashlight.
Instead of using batteries, the flashlight converts the heat from your palm into energy that powers LED lightbulbs.
The best part of this invention is not the flashlight, which, as we already noted is obsolete*. The best part is knowing that a 15-year-old is already playing around with this energy technology.
Hopefully in the next ten years she can do the same sort of thing for smartphones. Imagine just having to hold your smartphone for it to have enough energy to run?
Makosinski is a finalist in Google's Science Fair. To see who she's going against, click here »
