Stirling engines would be cheap to produce in mass quanities and really don't require that much material. Every new technology is expensive, but once it is accepted and mass produced it becomes relatively inexpensive.

My response was to all the negative comments. You can have a stronger lightweight hybrid car using new (or soon to be invented) composites. These cars would could zip along rather nicely, charge superfast using nano-technology batteries, and with solar powered Stirling engines not need to be plugged in for trips to work, mall, and food shopping.

The future is coming whether we like it or not.

Tell you what, You invest in Sterling engines and I'll invest in coal liquefaction. Lets get together in 5 years and the winner buys.

And most composites use what as their main ingredients? Resins made from petroleum! Not to mention energy used to create these designer composites.
