150 watt net output achieved Hi monkeys, The latest news is i have achieved a 150 watt net electrical output from my ORC heat engine. I'll now be looking to build an engine capable of outputing about 1kWe. I've already identified a load of the parts i'll need so i will hopefully get it under way fairly soon. I will be experimenting with non flammable R134A refrigerant as an alternative to Butane which will hopefully make the eninge more suitable for indoor domestic use. I will probaly step the next system up to use 24 or even 48Volts. You guys got any suggestions for useful features of a 1kWe system? What would you like to see? Stu.
