If it works as expected, it'll open the door for a no-fluids version
with a 'hard' piston that'll be suitable for generating electrical power
- a job for which the previous (wet) design just wasn't well-suited.
If you're interested, there's a new web page at
It's looking less and less like either an engine /or/
a pump. :)
