Green Vibes

I've been in this buzz ever since I read this article by Hank Green - it reminded me of an article on Popsci about something similar as a battery replacement for soldiers. Where Steve Beeby's device captures about 30% of the vibration energy in its environment, this backpack device invented by biologist Lawrence Rome generates about 7.4 watts of energy - enough to power your cellphone and iPod (or an iPhone), a flashlight and a host of other personal electronics.

Dr. Larry Rome also started a company Lightning Packs to make these special energy generation backpacks available to the general public. Not only are the packs good at energy generation (and thereby saving the environment), they also help provide ergonomic back support to the wearer! A video demonstration here (no sound):

Over the last few days I have really been touched by what humans have received from our environment and what we're giving back in return. I'm not asking all Indians to buy one of these backpacks and start selling electricity to Madagascar (Given our numbers, we could possibly even sell electricity to a small developed nation). Rather, I would like to take my reader's attention to what each one of us can do to help every other resident on the planet. Sooner or later, we'll all need to make big lifestyle changes to keep our growth sustainable. Let's start with the small little things - switch off that light if you aren't using it!
