Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as current combustion engines and about as efficient as fuel cells. Fuel cells are too expensive. He is assembling a complete free-piston engine prototype, a project that he expects to complete within a year.

Sounds familiar. This is just a beefed up version of you linear
genarator steam engine - except it's internal combustion.

This I think may be a possibility. If Kevin Flanigan comes here - he
said he's coming in a week - we could focus him on this as a solar
turbine candidate - after we do some building.

He may end up in a second Hexayurt.


A human being should be able to change a diaper, plan an invasion,
butcher a hog, conn a ship, design a building, write a sonnet, balance
accounts, build a wall, set a bone, comfort the dying, take orders,
give orders, cooperate, act alone, solve equations, analyze a new
problem, pitch manure, program a computer, cook a tasty meal, fight
efficiently, die gallantly. Specialization is for insects.
