Well OK Keith, I need to do some more work on this idea then.  I just can't
imagine a gas turbine spinning slowly enough to have any kind of generator
hold together.

In the mean time, here's a description of late night comedian Jay Leno's gas
turbine motorcycle:


He did a comedy routine about riding this thing up around Mulholland, and
some sap came up behind him when he was stopped.  He looked in his mirror
and saw the guy's bumber start to crinkle like a styrofoam cup in the
campfire.  {8^D

> Conceptually, you could replace the engine in a Prius with a turbine...

Jay also did a more serious interview regarding the bike.  The 150k price
tag wasn't the only thing stopping that bike, but rather that for all it's
300+ horsepower, it felt gutless, because it didn't accelerate all that
hard.  Reason: it takes a while to spool up the turbine to sixty thousand
RPM.  Imagine that.  {8^D  He also mentioned that it goes thru gasoline like
Senator Kennedy guzzling whiskey (his words, not mine.)

Ja I had a mid 60s vintage V8 in a pickup truck.  You had to drop half
dollar coins thru the carburetor on a regular basis, in the form of
gasoline, lots of it.

Good thing you didn't try it.  The tires of those days were generally not up
to the task.  I had a second cousin who learned that the hard way (Gary
Jones, perished violently in a 1962 Buick Wildcat, age 19 years.)

I still know how to do that.  {8-]  I had a '65 British bike with ignition
points until four years ago and did all the maintenance on it myself.  I
still had a timing light until about 3 yrs ago.  But new cars haven't had
ignition points for thirty years now, and I don't even know when external
timing belts went away.

Ja.  It left me behind about 25 years ago.  Hell computers left me behind 10
years ago.

Keith you and I are two lucky guys pal.  We remember back to a time when
life wasn't nearly as good as it is now.  May we live until it is way better
than it is now, or failing that, get frozen and uploaded when life is good.
