Startup Says It Can Make Ethanol for $1 a Gallon, and Without Co
A biofuel startup in Illinois can make ethanol from just about anything organic for less than $1 per gallon, and it wouldn't interfere with food supplies, company officials said.Ben Storan, a student graduating with an MA in Industrial Design Engineering from the Royal College of Art (RCA), has been working for the past year in conjunction with Imperial College to design an affordable personal wind turbine suited to the urban environment. The result is a unique design which uses vertical, rather than traditional horizontal, rotation. This feature gives a slower rotational speed, which allows the turbine to capture more energy from turbulent air flow, common to urban environments. It also means quieter operation. As a result, it is able to generate more energy than domestic models currently on the market.

The Sietch Blog » Watercone - An Ingenious Way To Turn Salt Wate
The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun. The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use. The Watercone is surprisingly a cone, that you place over a pan of salty water (or over a marsh, or any damp ground) leave it out in the sun, water evaporates, the condensation trickles down the side of the cone, at the end of the day you flip it over, remove the cap at the top and drink the water.
