Yup. I don't hate the French like these NeoCons do, but I certainly do not want to look to Paris for anything other than food, wine, and art. We should be leading the world in rail technology.
I think a solar heated steam engine using powerful mirrors/lenses is a future possibility for non-high speed trains. Google has even gotten involved, thank goodness:
Google: We're Going into the Solar Mirror Business
*snip*
The company's engineers have been focused on solar thermal technology, in which the sun's energy is used to heat up a substance that produces steam to turn a turbine. Mirrors focus the sun's rays on the heated substance.
Weihl said Google is looking to cut the cost of making heliostats, the fields of mirrors that have to track the sun, by at least a factor of two, "ideally a factor of three or four."
"Typically what we're seeing is $2.50 to $4 a watt (for) capital cost," Weihl said. "So a 250 megawatt installation would be $600 million to a $1 billion. It's a lot of money."
That works out to 12 to 18 cents a kilowatt hour.
Google hopes to have a viable technology to show internally in a couple of months, Weihl said. It will need to do accelerated testing to show the impact of decades of wear on the new mirrors in desert conditions.
"We're not there yet," he said. "I'm very hopeful we will have mirrors that are cheaper than what companies in the space are using..."
Another technology that Google is working on is gas turbines that would run on solar power rather than natural gas, an idea that has the potential of further cutting the cost of electricity, Weihl said.
"In two to three years we could be demonstrating a significant scale pilot system that would generate a lot of power and would be clearly mass manufacturable at a cost that would give us a levelized cost of electricity that would be in the 5 cents or sub 5 cents a kilowatt hour range," Weihl said.
