#1: Bolt-On Turbines
The Wind Cube is designed to work in an array, bolted onto the side of a house with a handful of other identical turbines. Just 15 of these small home turbines on a house could provide enough power for a family of four.
If you’ve seen the wind farms that are popping up all over the world, you’re probably already aware that wind power is one of the cleanest, greenest alternative energy sources out there. Aside from purchasing special “wind credits” from your energy company or installing a tall turbine in your backyard, there aren’t currently many ways to take advantage of the wind for powering your home. The Wind Cube concept would change all of that. It’s designed to work in an array, bolted onto the side of a house with a handful of other identical turbines. Just 15 of these small home turbines on a house could provide enough power for a family of four.
#2 :Electricity for Junk?
Typical chemical batteries – the ones we use in our flashlights and kids’ toys – are rough on the planet. Batteries that run on natural materials are much more eco-friendly but not usually as efficient. Such is the case with this cellulose battery. It uses special enzymes to break down and extract energy from cellulose, which is the same way termites digest wood. Although the system is woefully inefficient at this point, it is still early in the development phase. Hopefully someday natural batteries will be powerful enough to make harmful chemical batteries obsolete.
#3: Electricity from Jogging
When you see people running in the park, you probably don’t think of them as the perfect electricity generators – but they could be. The Green Wheel concept would put huge human-size hamster wheels in scenic locations and invite the public to climb in and take a jog for the good of their community. The wheel generates energy as it turns, which is then passed on to streetlights, stoplights and other public electricity-grubbers. Everyone would benefit from a setup like this: runners would still get their exercise, the city could rely less on fossil fuels and everyone could pay less to keep the city lit at night.
