Re: Monotube Javelin

Progress has been slow lately, as I have taken on a bit too much consulting work, building a 75,000,000 Watt geothermal plant in California, plus new design work for a new 100,000,000 Watt Sodium cooled nuclear reactor. The plan is to build a lightweight hull (similar to Margaret S lines) with an oi...

Typically running at 1 to 2 real horsepower, feeding propane at the standard USA pressure of about 11 inches water column gas pressure. I use standard 20 pound USA propane cylinders (9 kg total propane fill), and they do get ...

Surplus Center has been selling them for $125US recently, a good low price. Re...
