Hi EVerybody;

Hell! Wouldn't it be easier to string catenery above the strip? Like the
trolley buses use in SF and Vancouver? This is a prerfected system, over 100
years old, the dragsters just run trolley poles, maybe bamboo, to save
weight?You would be assured of power cutoff at the end of the strip, as
that's where the wires would end! I looked longingly at Vancouver's
stretches of long streight runs of overhead wire. BOY would the zombie GO on
600 volts! Hafta run late at night when traffic was light. Of course,
Vancouver Transit might have an issue<g>?>Freeky 200 amp "Hits" when all the
trolley buses were in bed for the night?

Steam Catapult from a junked aircraft carrier? Nah! No fun, with that a
stock Yugo would beat the Zombie.Nothin in the NEDRA or NHRA about overhead
wires, IS there?

What you saw was EJ Potter running his
"Slot Car" powered by an Allison airplane engine driving three aircraft
starter/generators hooked to the two rails going down the track.
EJ's "goonie" would rev the engine while EJ would flip the "Circuit Breaker"
then the goonie would accelerate the slot car as fast as he thought EJ could
handle, the only way EJ could release himself was to pull the circuit
breaker if he could reach it.
For those of you who never heard of "EJ Potter", he used to run exhibition
with his 327cu. in. Corvette powered motorcycle and SMOKE the tire (car tire)
the entire 1/4 mile run.


Gosh this makes me feel old, I met EJ in the mid 60's
when we went to England to put on a show for the Military..........oh yea, and
he crashed his bike there on the last run of the last day of the tour and we
brought him and his bike home in pieces.

God, I love to reminisce.

Jim Ludiker............the old guy that used to have an electric dragster.

Re: [EVDL] Nichola Tesla, Power hanging around.

just to throw out my own off-topic, they have power-tool drag racing,
and in the unrestricted (cheating) class someone just used a rubber band
stretched back from the finish line to the start, and that acceleration
blew away everything by a huge margin.

I will take this opportunity to plug my EV Train proposal again,
where you have locomotives running on the freeway which EVs can attach
into a train by magnetic coupling of their bumpers, and get recharged
from the regen in their wheels while being pulled along.

Re: [EVDL] Nichola Tesla, Power hanging around.

there is a fairly big problem with that idea...
or I should say a whole family of serious problems but one of them takes
the cake :)
can you think of what that might be?
has to do with the length of the trains...

Re: [EVDL] Nichola Tesla, Power hanging around.

haha.. youd get a nice surprise when you pulled up at your house and realised youd brought the rest of the train home with you.

Yeah! And providing food and drinks for all your newfound" Friends?"
Whynot have a conventional flatcar train that you drive onto, sit back and
let the train's engineer pull for you? Amtrak SHOULD expand the Auto Train
ALL over USA instead of just from VA to Fla. Amtrak has to fight for mear
survival nowadaze in Congress. With the Best Govt. Oil Money Can Buy, it
isn't easy. They want you to BUY GAS and spend! This is why we don't have
interburban electric Rys anymore. Didya know you could, with enough
patience, and nickels, ride fro m Portland ME to NYC and beyond in ELECTRIC
trolley cars?This was back about when the Titanic went down, though.In my
PDX drive I sure saw enough BNSF trains carrying trux, well, the trailers.
Sure woulda been nice to put the CAR on there and wander back to the dining
car, or big plushy coach seat. Amtrak does NOT buy their seats from the
airline seat supplyers!

Keep on training

Bob
