Car that runs on air

[TenPenny]

I was talking about this:

Watch "Opposed Piston Opposed Cylinder Engine" Video at Engineering TV


It’s called OPOC (Opposed Piston Opposed Cylinder), and it’s a turbocharged two-stroke, two-cylinder, with four pistons, two in each cylinder, that will run on gasoline, diesel or ethanol. The two pistons, inside a single cylinder, pump toward and away from each other, thus allowing a cycle to be completed twice as quickly as a conventional engine while balancing it's own loads.
The heavy lifting for this unconventional concept was performed Prof. Peter Hofbauer. During his 20 years at VW, Hofbauer headed up, among other things, development of VW’s first diesel engine and the VR6.
The OPOC has been in development for several years, and the company claims it’s 30 percent lighter, one quarter the size and achieves 50 percent better fuel economy than a conventional turbo diesel engine.
They’re predicting 100 MPG in a conventional car.

The old Fairbanks Morse diesel locomotive engines were this style, two pistons in each cylinder.

Complicated and not reliable.

That was then. Technology has marched on. I'm not defending this design as all
I know is what I've read....but I'm keeping an open mind. Seems worth checking
out, at least.

Vehicle that runs on hot air???

Halleluyah, a car for liberals! Unlimited supply of fuel!

;-) Think of it.... You'd never have to walk again - especially if you're passed on the left.

I wonder if the air motor concept would work better in a rotary or turbine engine base? Fewer moving parts makes more energy available to drive the wheels.

Kind of a cool idea though I wonder what the other issues are like heating and air conditioning, safety and parts availability? Looks like a great little commuter though.

YouTube - ‪*** Car Runs on Air! FREE ENERGY! Even Self Sustaining! Why are these not made by GM?! ***‬‏

OP, science is not your forte, is it?

let me fill you in on some basic science: where there are moving parts, there is friction, where there is friction, there is heat, where there is heat loss, there are energy losses, where there are energy losses.....ie THE REAL WORLD!.......there is no chance in hell that perpetual motion will ever happen

Take my advice, the next time you see an article about perpetual motion, run. run very far.
