Good link but they were way ahead of their time. If I remember correctly Chrysler came out with the Patriot race car before they did and it used a Carbon fiber horizontal flywheel to store energy and a turbine engine that ran on propane. It might have been a Garret. The problem was the surface speed of the outer diameter of the flywheel was constantly at the verge of disinigration. So it was to damgerous for production use. As for the Tesla they may have the same danger problem after the Sony laptops started exploding from over heating when charged. Now Bob Lutz may be smarter than everyone thinks because he waited for other to try and came up with a better battery in the end. The Volt will use a Litioum Ion Phosphate battery that is completlely safe and will not blow up when charging or when over heated. It can even be shorted out in a crash with out any explosions. I think GM will have a big lead over the Prius Metal Hydride battery and take the world by storm once they release the Volt. The battery company that will make the battery for them is located in Mass and the parent company is owned by Chevron. Keep an eye out for the IPO.
So if Capstone wanted to sell turbines like they should be they would be teaming up with companies like mine to market their products. Just like this company is doing with their batteries. They are snooooooooozing. I could be selling their units for 1/100 of the money they are spending now on marketing and producing more sales that they are.
