Hi all, Welcome to the new group. I hope this place takes off soon. I suppose we'll be a bit of an odd lot, however, given the current popularity of obese...

I don't know, do you? I imagine they aren't light (yet), and based on what I've heard about the heat rejection of those things (anecdotally), they can't be...
... I've just been handed a copy of Automotive Engineering International, March 2001. OK its two years old, but hey that is better than nothing. These things...
HOUSTON--February 12, 2003--Researched by Industrialinfo.com (Industrial Information Resources, Incorporated; Houston, Texas). If, two months ago, you were not...
Hello... I just joined the group...I'm 38 and living on the central coast of California... I'm looking foreword to the no nonsense straight facts on what is ...
Golf carts aren't a great place to start, their motors are typically only 60% efficient, and the motor controllers are pretty crude. Option 2 looks pretty good...
thank you for your input Greg.... here is a bit more on what I'm thinking... Option one... the Golf cart would use only the frame and spindles, brakes,...
Tim, I may be mistaken, but it's my guess that Greg was suggesting that you borrow vehicle design cues (suspension, chassis, etc) from the solar vehicles, but...
Yes, that's what I meant. There is no point in reinventing the wheel, and cyclists and solar car racers have had a long time, and a great incentive, to develop...
Just found the group, I'm the happy owner of Civic Hybrid #1515 in Dallas, and am quite interested in boosting my milage.(current 56.3 after 20k miles) I...
... It's been my experience that such claims are meant to be interpreted "boost HP, mileage... vs plugs that needed to be replaced." The claims are never...
BTW, how do you like the hybrid Civic? Have you owned a Civic before? I've had two conventional Civics in the past, and I've often wondered how the hybrid...
Greg... thank you... I see your point... I agree... no need to reinvent the wheel... Nice looking car by they way :) ... I have fallowed these off and on for a...
First off, thanks to Ivymike for mentioning this group over at 'thehondacivicclub' group otherwise I never would have found it. Here's what I posted over there...
After reading the article on the MDI air powered car I started tossing around some ideas in my head. I don't know if this design would even work so I'll ask...
Hey Tim Man, that period key on your k/b gets a workout. Glass skinned foam and resin is a superb cheap way to build a structure, that's exactly what we used. ...
Hey Joe There is a basic problem here - you are trying to suck more energy out the air than you are putting in. Air powered cars work (up to a point), but they...
Hmmmm, hadn't thought of that. I havn't factored in much of anything yet though. The whole concept is just a bunch of sketches. Another idea was a regular...
... power. ... Same problem though, plus another. Since you're not adding energy anywhere, you can't take it out either (not for long, anyway). Also, I...
Just found the post on eng-tip.com, and like the concept of this group. I have spent over a year working on a linear internal combustion engine that pumps...
Hi Ed I saw one of your posts on eng-tips, it sounds interesting. You do know that these things are already available - some pile drivers, and other thumping...
Hi Greg, Actually the hydraulic pumping idea isn't new either. This link will show another design, http://www.sae.org/ohmag/techinnovations_04- 00/02.htm. SAE...
90% isn't too bad, if that is the total loss in the system. An automatic gearbox and conventional diff might be slightly better than that, but only by a couple...
... Hi Joe... I see the gas powered hybrid as an electric car with a cheap (known technology?) battery... I feel the auto makers (Toyota and Honda) as needing...
the only way I see a compressed air motor working is similar to the post earlier with hot air and cold air a sterling motor. compressed air just can't store...
