I am holding US$10 million for you in Swiss bank account. If you only send me check for 10% of that I release funds in your name. Please hurry…

Right after you give Kundan Bonde all your ideas you should go ahead and post your social security number on here too. Don’t forget your mother’s maiden name.

I am interested in making prototype of air operated engine. So, would you please give me the details about how can I make simple model of air operated engine. Also, please give me details such as design of storage tank, piston, cylinder, connecting rod and information about total assembly.

Very thought provoking I love R@D .I would be intrested in building the frame, and chassis for this creation have all the tooling I also think outside the boxs as too say a craftsman. We could build the frame too be the tanks and the swingarm .Also airsuspension for the plush ride all in one tank in the swingarm .At this time I hold a really cool patent on a nodowntube frame built for V-Twins ! You can see the patent if you look up cantilevered frame under patent applications! Keep pushing the dreams until it becomes reality!

Thanks for the comments.

Telekom. Weight is a valid concern but the projected weight of the project is very low. While a high CG isnt ideal the visual CG of the bike is higher than the actual CG. I dont remember right off hand but i think the weight of all 4 tanks was around 40-50lbs full. With the regulators, valving and pipe work being on the low end, the CG is on par with a current standard motorcycle. The suspension and wheels are a fairly large portion of the bike weight(proposed). Nearly 100lbs is wheel/suspension/frame, another 50 for the engine and 100 for all related air equipment. Several of my inital concepts had low slung tanks but i felt tank protection was more of a concern than a slightly shifted CG. The weight bias is slightly forward. I prefer a front heavy(52%) weight bias.

Rafe, those are very good points you bring up and thats something that will need to be addressed for sure. Id like to stay away from C02 simply because one of the main points is being able to just plug in and recharge(even if recharge times are long). I know it takes nearly 45mins to fill an 80cuft scuba tank which equivalent to the 4 on the bike. There is certainly a long list of pros/cons and give/take that need to be weighed out in a QFD. Of course until I have a concrete engine design the rest isnt really a concern.

Years back when i started thinking about alternative energy my first direction was steam, but my ideas were power hogs unfortunately but I really need to look back into the things you mentioned.

Again thanks for the great comments. Hopefully I will have some new ideas to share soon.

Just another idea from even further off the wall. How about using CO2 as a power medium? Similar heat concerns as compressed air but at room temterature, it liquifies at about 700 psi so could be stored as a liquid! This would increase the power density inside the bottles considerably while reducing the safety concerns about pressure vessels in an accident.
Hey Matt! Thanks for stirring up the old little grey cells!
Lotsa Luck!
