Re: [EVDL] homemade Hummer to have turbine jet engine recharge super capacitor batter

The difficult part of his current project involves the uncharted
territory he's entering. The high speed turbine / generator is
certainly possible, and I found a few references to prototype devices,
but at 60,000RPM, it is a very close tolerance system. I'm not even
sure if there are off-the-shelf high power generators available for
the rated RPM he is looking for - my quick Google search didn't
produce anything in production. I'm sure a surplus starter generator
would work, but I can't imagine it is designed to produce the amount
of power he is hoping to produce in a few seconds runtime. Anyone fly?
It sounds like he's using a helicopter turbine, anyone know the
typical output from their starter generators?

The other problem with the "just bolting something up" idea is the
fact that these supercapacitors he says he is going to use simply
don't exist yet. Sure, we've had a few companies claim they are coming
to market, but there haven't been any demonstrations yet and people
who have been on this list far longer than I have chimed in just over
the past few days that these capacitors have been claimed before and
we are already well past the dates they were supposed to go to market,
without even seeing demonstrations of working prototypes. At the
moment, they are vaporware.

As for the DIY garage philosophy driving his past accomplishments ..
it sure did, but they were in a whole different ballpark. As far as
the articles on him are reporting, his claim to fame are a few
biodiesel conversions. Very respectable from an environmental
standpoint, but hardly cutting edge. The fact that he did what GM
claimed was impossible just tells us he knows his way around a diesel
engine, and that GM is still outspoken against most things
non-petroleum.

If I misinterpreted something in the articles out there, please
correct me. So far, though, I don't see him building this turbine
powered series hybrid running on
