i would like to creat a large steam engine, big enough to power a vehicle made of bikes that seats 3. Answered
the vehicle would be pedaled until some speed was reached, then the engine would be switched on.
the bike contraption would consist of two bikes side by side, held together by lumber. two of the seats would be mounted in the bikes original seat holes, on the side, and the third would be in the middle, the driver. the front wheels of the side bikes would be removed and he front end of a third will be used in the front. the vehicle will be like a giant, steam powered tricycle.
Other engine ideas, other than gas powered, would be greatly appreciated, the cheaper the better.
