there is really no need for gears in the next gen cars you could simply change the motor timing and or the coil wiring on the fly. And unlike autogyro Ive raced it and won.

Can't tell you how it works, but is ok to run on seawater.

Well, you're late, it was already debunked. Salt water as fuel

So, the challenge is still there: can you debunk it? I would love to to rename this thread "The James Randi Award Thread".

During an interview with a newspaper reporter recently, I was asked a common question: "Do you feel like we're losing the battle? That people are increasingly turning away from science and towards woo-woo?" And I answered, as I always answer, "No."

--James Randi--

So, as nitpicky as I have become about insults, I'm all in for trying crazy ideas. I trust the judgement of the forum, each day a little more, specially after watching the skepticism displayed by bazanaius and yourself, following an illustrious list of predecessors: well done.

D'oh, beaten to it! All that brain-xercise wasted, but inspired by the originator of this thread, I am now emancipated from the slavery of physics and maths, why all I can say is; "I'll be back."

Well, the net is excellent at spreading nonsense, wouldn't you agree? On the other hand, not everybody is gullible and the gullibility of the forum is quite small, even if this includes listening all the claims.

The salt water story shows that "large numbers of intelligent amateurs are much better than the so-called professional journalists" when that kind of stories are involved.

When I see threads like this one, I think that traditional journalism is dead. Good riddance. Welcome to the forum.

OMG!! NEW IDEA!! Let's make an engine that uses the laughter of your children to ignite everlasting combustion of unicorn blood!! It's soooooo efficient!!

Slaughtering unicorns is not very green is it now. Besides, aren't they on the endangered species list?

A friend of mine built the first slot car racing cars long before Scalextric in 1940. The British bomber crews used to play on it between raids on Germany.
True or False?

Transmissions can improve the efficiency of any electric motor. A/G 2009.

Haha. That's an easy one autogyro. The answer is false. Adding a transmission decreases efficiency when you only have one gear because there is friction, which is wasted energy. However, by adding multiple gears, you can increase efficiency by using less power for higher revolutions by multiplying crank speeds. Also, a transmission for an electric motor deals with constant, and ridiculous I might add, torque. Very different than a conventional IC tranny.

Considering the interest in electric motors and transmissions:
"Abstract—A new infinitely variable automatic transmission
called the RESATRANt that automatically
changes its speed ratio in response to load torque
being transmitted is presented. A prototype has been
built and tested on a conventional three-wheeled
electric motor propelled wheelchair. It is shown theoretically
that more than 50 percent reduction in power
during hill climbing may be expected when a transmission-
equipped wheelchair is compared to a direct-drive
vehicle operating at the same voltage . It is suggested
that with such a transmission, wheelchairs can use
much smaller motors and associated electronic controls,
while at the same time gaining in efficiency that
results in longer operating distances for the same
battery charge. Design details of the transmission and
test results are presented . These results show a
substantial reduction in operating current and increased
distance of operation over a test course."

Thank you Carlos. It loses a little in translation but proves the point.
CVT's and TVT's have a use in electric propulsion where the torque transfer is low and there is a need for multi stop operation.

On high power light weight electric traction systems they become less efficient and on real heavy traction such as rail locomotion it becomes more useful to use segmented motors and or fine control over voltage/amperage to reduce the need for gear ratio range.

However for ordinary car use a transmission proves more efficient, which was why a three speed unit was built into the Tesla. It was taken out because they could not make it work for longer than 2000 miles.
Transmissions are therefore 'the' area of future vehicle development.

Sorry the answer is yes.
The engineer in question was Wing Commander Ken Wallis, who built a 'steering' slot model car racing system in 1940, when he was a serving bomber pilot in the RAF. He undertook over 100 raids, most of them long before the Americans decided to join in and bailed out once and also crash landed once in Vickers Wellington's designed by Barnes Wallis a relative, who also designed the bouncing bomb, the tall boy and grand slam bombs and the R100 airship.
One of the wars 'real' unsung hero's.
He used to build his own electric motors then, as there were non that small available. Ken still flies at 94.

True or False?

They can if you have a motor that doesn’t have a large efficient rev range. But you also lose drive line efficiency its a balancing act. The car I raced was a little clunky off the line with the motor cogging but from 25 - 80 mph was 95-98% to the ground. Show me a gear box that can do that.

Not much good in traffic then flyn?
I had a Ford Cortina Savage with a 351 Cleveland V8 and 500 bhp years ago.
I used it for towing after we had won everything in super with it.
That car would take off in top gear and go all the way to 140mph.
Top was good enough for town work as well.
So what is it you were saying about no need for gearboxes and electric traction flyn?
The problem is the lack of appreciation of what has gone before and the reliance on computers at the expense of common sense.

it was fine in traffic just not as efficient. it only cogged till about 5mph probably less time than you spend slipping your clutch. And I didnt need 500hp to do it.

you can blame computers all you want im not taking the bait. If you cant use one thats your problem.
