Turning Trash Into Gas
CleanTech Biofuels, HFTA UCal Berkeley and Green Tech America are on a mission to make ethanol from garbage. Clean Tech claims that they can reduce landfill waste by 90% - which would mean a huge reduction in greenhouse gases.
Add to that the easing of the problem of overflowing landfills and fewer places to site new ones, and it’s clear that the project will make a huge difference to the environment and the consumer.

$45 Trillion is Needed to Halt Global Warming
The International Energy Agency says oil use and CO2 gases are “clearly not sustainable” and calls for an “Energy Revolution” to reduce the world’s dependence on fossil fuel.
Unless emissions are cut 50% by 2050, thousands of nuclear power plants and wind farms are built, the earth will not be able to overcome the effects of global warming. More …
Scrubber Could Help Remove CO2 From Air
A group of US scientists say that they’re less than two years away from a prototype machine that will remove CO2 from the air. The scrubber, as they call it, will be small enough to fit into a shipping case and will remove as much as a ton of CO2 a day.
While this isn’t an answer for the problem of global warming, it’s a good start and could help slow it down while other solutions are worked on. More …
Small May Be the New Big In Renewable Energy
Huge wind farms, large solar collectors and towering hydroelectric dams may be what you think of when you think of renewable energy, but it’s not what comes to Agustin Ortegui’s mind.
He’s the Mexican-born inventor who has come up with the concept of “Nano Vent-Skin”, a substance that would cover a structure in a solar material that is embedded with micro-turbines. Instead of adding on, the material would be an integral part of the structure right from the drawing board. More from Inhabitat…
Free Energy From Waste Heat
Of course, the heat has to be paid for first, but if it’s then reclaimed to make power, the savings are enormous. This is why a major Northeastern US paper company has hired Thermal Energy International of Ottawa, Canada to install and operate a $20 Million waste heat recovery system.
Even if oil prices don’t rise as predicted, the project will mean $40 Million in fuel savings over the course of eight years. More from Clean Break …
