I think some people who posted here that are interested in generating electricity by burning wood, creating steam with a Combined Heat and Energy system may want to check out my work. I have made some videos showing my system design. I just increased my steel water tube boiler pressure vessel to 3 cubic feet from 2.3 cubic feet, the videos were made with the smaller volume boiler. I recently built and tested a piston steam engine I designed hooking it up to the boiler I built in 2009:

I had previously built several turbines and tested them and also piped the exhaust from the turbine into my garage and heat the garage that way and also have a low/no pressure radiator loop system to heat when I am not generating electricity: [youtube]https://www.youtube.com/watch?v=bTjikSKJUH0&t[/youtube] The turbine has been in service for two years now and seems reliable and easy to operate compared to the piston set up but has only put out about 650 watts on the same boiler as the more efficient piston engine. I have studied code and law of my state and several other states and found this system to be legal in many states. I would like to actually go into business building and installing the complete system and supplying parts of the system to people who build some of the equipment themselves. Please let me know what you think. Thanks Ken Driessen
