Car Talk advocates $.50 gas tax

Car Talk is a NPR show where two brothers who are mechanics take caller's questions. This past show Ray renewed his call for a national gas tax, including a new idea for who can reinvent themselves as train manufacturers.

Here is an excerpt from the show and website:

"I think it's an idea whose time has come," he said. "I know most politicians have been too wussy to do it, but I think the logic of raising the gasoline tax right now is unassailable.

"Gas is less than two bucks a gallon. There's never been a better time to do this. If we added a 50-cent national, gasoline tax right now, and gas cost $2.50 a gallon, would that be the end of the world? Hardly.

"This new tax would generate between 50 and 100 billion dollars every year for the treasury. That money could be used to help rebuild our crumbling roads and bridges, and develop new technologies for more fuel-efficient cars... further decreasing demand for oil. This is a way for us to get on the wagon, and stop sending money to countries that don't like us. We could become energy independent.

"The other thing that the gas tax revenue could fund is high-speed-train infrastructure between major cities. And who would build all of the new high-tech, high-speed trains we'd need? GM and Ford! We'd help them start a mass-transit division, convert some of those factories from building inefficient gas hogs to building high-speed trains."

What do you think? Is Ray on to a genius idea that will point our country towards a sustainable transportation future? Or does he have his headlight firmly implanted in his tailpipe? Is it even a political possibility?

Says our humble co-host, "I'm sick of people whining about a lousy 50-cent-a-gallon tax on gasoline! I think its time has come, and I call on all non-wussy politicians to stand with me, because our country needs us."

Fiat shows solar-panel wrapped 'Panda of the future'

'Leccy Tech Fiat's latest take on the electric car, the Phylla, has been revealed at the Turin Environment Park.

Weighing just 750kg – of which 150kg is the battery pack – the 2+2 Phylla has a quoted range of 145km from a lithium-ion battery pack, or 220km from a lithium polymer unit. Performance? 0-30mph takes six seconds and the top speed is just over 80mph.

Recharge time from a domestic wall socket is said to take between three and four hours, while nearly every available inch of body work is covered in solar panels which are said to generate up to 340W. The electric motor provides drive to all four wheels and has an average power output of 27kW and a peak output of 54kW.

No announcements were made regarding the potential manufacture of the Phylla, so its real importance is an indicator of what Fiat think a 'leccy Panda may look like a few years down the road.

Fish-inspired power generator can work in slow-moving currents

Think like a fish not like a bird, say researchers trying to harvest energy from water currents. Their new fish-inspired power generator can work in slow-moving currents where traditional turbines are less effective.

Tidal streams and moving rivers in the United States could generate 140 billion kilowatt-hours per year, or about 3.5 percent of the nation's electricity demand, according to the Electric Power Research Institute (EPRI).

Most of the attempts to tap this potential have employed underwater windmills. These so-called tidal turbines use the force of lift to turn their blades.

"We live in air so we are used to lifting surfaces that support birds, sail boats and airplanes," said Michael Bernitsas of the University of Michigan.

In water, however, Nature has devised a different strategy. Most natural swimmers — from tiny sperm to giant whales — create vortices (or little whirlpools) that they push off of to propel themselves forward.

Bernitsas realized that these same vortices could be used to drive a generator. He and his colleagues have created a machine called VIVACE (Vortex Induced Vibrations for Aquatic Clean Energy), whose cylinders oscillate up and down in moving waters.
