Though below is not specifically with regards to a motor I am sure this group can provide some help. Hello, I am a novice and I am seeing a great deal of...
Solar power really isn't a practical power source for a 2500 to 3000 pound vehicle. But it is still useful for powering your home, especially if your local...
... necessarily offer advantages over a turbine for the purpose you’re proposing. My own fascination with free pistons is as a means of generating much ...
Thank you, both, for the responses. I am currently also building a turbine version. The difficulty with this is that although efficient turbines are readily...
Give me a minute or two to get up to speed here... You mentioned a free-piston Stirling engine, and a problem with actuating some valves. Since a normal...
The idea I am presenting may not be a true stirling engine however I obtained much of the design idea's from "free piston stirling" schematics on the web and...
Max: Just poking about on solar stirlings, I came across this: http://www.clean-air.org/sundish.htm Using a STM Stirling (experimental, very sophisticated and...
I've seen the 2nd belize article but not the first. Am also unaware of the home built deep cycle batteries. Will look into that, thank you. Max ... ...
A Crescent shaped valve is not a good idea. Circular valves are by far the best. Anytime you try to do an oddly shaped valve you are going to create problems...
Boiling pentane or butane? Those are hydrocarbons. They are gaseous (above boiling point) at typical atmospheric temperature, and any attempt to heat those...
I agree... I don't think people understand the high temps that can be generated by a simple solar reflector... it is not uncommon to reach 3000 degrees... ...
I did some searching around. Sorry I didn't save the URL's, but if I can find them again I'll repost them. The temperatures achieved by solar reflectors are...
Yes normally gaseous except in winter where temperatures low. Thus only need small temperature change for large change in volume. Summers may use high BP...
I was looking on TV at a show on trucks, and they presented the new Ford diesel truck. A big monster as usual, but with an interesting feature: some form of...
Thanks, Isaac. I certainly did. Find it interesting. Not that they're really getting that much out of it -- but it kicked off for me a really nice train of...
Here we go. Is anyone sick of waiting for fuel cells to come out? How about the ridiculous costs of batteries and their tremendous weight for high power...

... awesome. ... more ... Unfortunately, if your going to try to store energy by compressing hydraulic fluid, you'll need compressors, revervoirs and high ...
I’m going to disagree with your reasoning. Hydraulics should work as good or better than electrics for hybrid cars. The energy density that can be obtained...
I agree with Ed. Hydraulic horsepower is pressure (in psi) times flow (in gpm) divided by 1774 as I remember. High pressures can store some respectable energy....
Hold on a second John... "power steering systems capable of several horse power"??? Hmmm never thought about that... how many horse power??? does any one know...
Power sterring has to do a good job with engine at idle, but hp goes up as engine speed. It's possible that the power sterring pump could charge the accumlator...
At 600 rpm engine speed our old model gave 0-150 psi >2.5 gpm 700 psi, 2.5 gpm 1400 psi 0 gpm at 1500 rpm it gave about 1.5 gpm at 0-150 psi There is an...
I'm not sure how Greg's experience fits with the Nichols motor. Nichols motor seems quite promising; Greg's news is much more disappointing. Can anyone...
I wouldn't use a PAS pump for a power circuit - the efficiency is probably only 60% or so (that is a guess - nothing on a production car (except a turbo) seems...
The problem with a mechanical regenerative breaking system is that it would require some form of centrifugal clutch, and the danger of mechanical failure and...
