A revolutionary device that can harness energy from slow-moving rivers and ocean currents could provide enough power for the entire world, scientists claim.
The technology can generate electricity in water flowing at a rate of less than one knot - about one mile an hour - meaning it could operate on most waterways and sea beds around the globe.

You hear about them every year: gee-whiz, plug-in, battery-powered vehicles poised to change the world. Granted, they’re tiny, or expensive, or both. And if they ever make it to the United States, they’ll be downgraded from electric vehicles (EVs) to neighborhood electric vehicles (NEVs)—glorified golf carts with a top speed of 25 mph. But overseas, where getting gouged at the pump is a fact of life, EVs are a growth market.
With Ford's chief executive in Washington contending his company is nearly as bad off as General Motors and Chrysler, Ford's messaging might seem, well, a bit crazy. But if the Fusion is as good as Ford promises, it could very well be a step in the right direction. After all, the hybrid gets 39 mpg in the city, and, according to Fields, 700 miles on a tank of gas in city driving.
A joint venture between Royal Dutch Shell and Iraq's state-owned South Gas Co. could give Shell a 25-year monopoly on production and exports of natural gas in much of southern Iraq - the biggest foreign role in Iraq's oil and gas sector in four decades.
A tree fungus could provide green fuel that can be pumped directly into vehicle tanks, US scientists say. The organism, found in the Patagonian rainforest, naturally produces a mixture of chemicals that is remarkably similar to diesel.
Imagine running a parking meter backwards and actually being paid to park your car. Along those lines, electric vehicles might one day make money for their owners by providing electrical storage for the nation's power grid.
