Steve said that scaling down from full size isn't all that hard with the exception: you can't scale down water. The brake control valve that he designed wasn't working correctly. It worked fine using compressed air as a test, wouldn't work with steam. The holes in the valve that control the flow are maybe 1/32ond. It took Steve a couple months to figure out that if the steam condensed, a drop of water could block these holes and the brakes wouldn't work. Enlarging these holes by 0.010 inch solved the problem. Shows how hard these machines are to build from scratch. The steam turbine generator, spins 10,000, produces 6 volts. One of the few things Steve has to buy instead of build, cost- $650. |
