Future energy
Renewables, fuel cells, hydrogen, and efficiency

Thomas L. Friedman: No Mullah Left Behind:  Excellent NYT column, reprinted widely in the US and overseas (India, Pakistan, Europe).  "The [WSJ] added, the conservative mullahs are feeling even more emboldened to argue that with high oil prices, Iran doesn't need Western investment capital and should feel "free to pursue its nuclear power program without interference." This is a perfect example of the Bush energy policy at work, and the Bush energy policy is: "No Mullah Left Behind."

By adamantly refusing to do anything to improve energy conservation in America, or to phase in a $1-a-gallon gasoline tax on American drivers, or to demand increased mileage from Detroit's automakers, or to develop a crash program for renewable sources of energy, the Bush team is - as others have noted - financing both sides of the war on terrorism. We are financing the U.S. armed forces with our tax dollars, and, through our profligate use of energy, we are generating huge windfall profits for Saudi Arabia, Iran and Sudan, where the cash is used to insulate the regimes from any pressure to open up their economies, liberate their women or modernize their schools, and where it ends up instead financing madrassas, mosques and militants fundamentally opposed to the progressive, pluralistic agenda America is trying to promote. Now how smart is that? ..

[We need] a "geo-green" strategy. As a geo-green, I believe that combining environmentalism and geopolitics is the most moral and realistic strategy the U.S. could pursue today. Imagine if President Bush used his bully pulpit and political capital to focus the nation on sharply lowering energy consumption and embracing a gasoline tax.

What would that buy? It would buy reform in some of the worst regimes in the world, from Tehran to Moscow. It would reduce the chances that the U.S. and China are going to have a global struggle over oil - which is where we are heading. It would help us to strengthen the dollar and reduce the current account deficit by importing less crude. It would reduce climate change more than anything in Kyoto. It would significantly improve America's standing in the world by making us good global citizens. It would shrink the budget deficit. It would reduce our dependence on the Saudis so we could tell them the truth. (Addicts never tell the truth to their pushers.) And it would pull China away from its drift into supporting some of the worst governments in the world, like Sudan's, because it needs their oil. Most important, making energy independence our generation's moon shot could help inspire more young people to go into science and engineering, which we desperately need.

Sadly, the Bush team won't even consider this. .. President Bush has a better project: borrowing another trillion dollars, which will make us that much more dependent on countries like China and Saudi Arabia that hold our debt - so that you might, if you do everything right and live long enough, get a few more bucks out of your Social Security account. 

The president's priorities are totally nuts."

Nanotubes crank out hydrogen: "Several research efforts are using materials engineered at the molecular scale to tap the sun as an energy source to extract hydrogen from water. Researchers from Pennsylvania State University have constructed a material made from titanium dioxide nanotubes that is 97 percent efficient at harvesting the ultraviolet portion of the sun's light and 6.8 percent efficient at extracting hydrogen from water. 

The material is easy to make, inexpensive, and photochemically stable, according to the researchers. The 97 percent efficiency is the highest reported, according to the researchers. There is one catch -- only five percent of the sun's energy is ultraviolet light.   The researchers are working to find a way to shift the response of the nanotube arrays into the visible spectrum.  The key to making titanium dioxide nanotubes that efficiently harvest the energy from light is controlling the thickness of the nanotube walls, according to the researchers. Nanotubes 224 nanometers long with 34-nanometer-thick walls are three times more efficient than those that are 120 nanometers long with 9-nanometer-thick walls.

The researchers made the titanium dioxide nanotube material by mixing titanium with acid and electrifying the mixture, which caused the tiny tubes to grow, then heating them to cause the material to crystallize."  [via WorldChanging]  1:01:08 AM  permalink
