Hot Flat & Crowded: Why We Need a Green Revolution & How the U.S. Can Lead It -A Video

The best chapter in New York Times reporter Thomas L. Friedman's new book, Hot, Flat and Crowded, traces the correlation between the price of oil and the pace of freedom in petroleum- producing states between 1975 and 2005. When prices went up, freedom went down in places such as Iran, Russia and Nigeria.

"America's problem," Friedman writes, "is that it has lost its way in recent years,'' he says. Earth's problem is that it's getting ``hot, flat and crowded. That is, global warming, the stunning rise of middle classes all over the world, and rapid population growth have converged in a way that could make our planet dangerously unstable.''

Electric Cars Driving the Pols at Democratic Convention

The Democratic Convention is showcasing not only our most probable future president, it's also showcasing our most probable future mode of transportation: the electric car. Ten electric vehicles, including the Tesla Roadster, Toyota RAV4 EV, AC Propulsion eBox and a plug-in Toyota Prius will be featured, giving rides to policy makers and the public in order to emphasize the desire of electric cars for the average commuter and show that EVs are a very real solution to the current energy and climate crisis.

Nano-Solar Power -Will it Be the Next Revolutionary Technology?

Nanotech has fueled the imaginations of science-fictioners for years, with world-changing and ending inventions in equal measure.  But the real strength of this molecular machinery is how it can upgrade existing concepts, and this time it's solar power's turn.  Two trendy technologies and one potentially revolutionary application.

MIT Scientists Mimic Plants' Energy Storage System -Discovery to Unleash Solar Revolution

Sunlight has the greatest potential of any power source to solve the world's energy problems. In one hour, enough sunlight strikes the Earth to provide the entire planet's energy needs for one year.

Daniel Nocera, Henry Dreyfus Professor of Energy at MIT

In a revolutionary discovery that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.

"The Challenge of our Lifetime": 100% of Our Electricity from Renewable Energy & Clean Carbon-free Sources in 10 Years

Won't it be great when we finally have a president who can call on our better angels and commit the U.S. to solar, wind and geothermal power? In a speech yesterday in Washington, D.C., Gore called politics the biggest barrier to change and referred to the call for more drilling as a means to lowering gas prices “perverse,” because it will take too long and increased production will never keep up with demand, thus prices are unlikely to go down.

World 1st: Wave-powered Boat Completes Journey from Japan to Hawaii

In February this year an intrepid 69-year-old eco-sailor named Ken-ichi Horie began his journey on a wave powered boat from his homeland in Japan on a 4,350 mile journey to Hawaii in 111 days at a speed of about 1.5 knots.

MIT "Windows" -Scientists Create a Solar Concentrator to Help Power Buildings They are Part Of

MIT technologists have invented a new approach to harnessing the sun's energy that could allow windows to provide not only a clear view and illuminate rooms, but also use sunlight to efficiently help power the building they are part of.

The innovation involves the creation of a novel "solar concentrator." "Light is collected over a large area and gathered, or concentrated, at the edges," explains Marc A. Baldo, leader of the work and the Esther and Harold E. Edgerton Career Development Associate Professor of Electrical Engineering.

As a result, rather than covering a roof with expensive solar cells (the semiconductor devices that transform sunlight into electricity), the cells only need to be around the edges of a flat glass panel. In addition, the focused light increases the electrical power obtained from each solar cell "by a factor of over 40," Baldo says.

Single-Celled Fuel -Is it a Solution to the World's Energy Problem?

We've always known that the Sun supplies us with more energy than we could ever need, if only we could harness it properly.  Suggested solar strategies have ranged from the Bond-ian (the JAXA orbital solar collector) to the workmanlike (the constant improvement of solar-panel efficiency), and now we can add a gooier option: bacteria.

These single-celled organisms are the biggest success story in history, and by sheer numbers they still kick the hell out of all us higher animals (and not just when they're making us sick) while still retaining cellular complexity that the even more numerous viruses lack.  They've been touted as a solution for everything from the energy problem to pollution.

Will "Th!nk" Ignite an Electronic Car Revolution in the U.S.?

Th!nk Global, yes, think with an exclamation mark, gas-free, city cars are poised to invade the U.S. from its Norwegian  where some 1,200 Think concept vehicles are driving on European, mostly Norwegian, roads today. Th!nk is buoyed by undisclosed funding injection by Silicon Valley venture capital firms, Kleiner Perkins Caufield & Byers and RockPort Capital Partners, will be introducing the Ox, Open and City models starting in 2009 -and it can't be too soon!
