Elec Power thread for the derailer
#4
Yup - high pressure and heat need very close monitoring the first steam engine patented 1694.... james watt came along and made it practical in 1760 or so

Many cultural anthropologists (yep spent some there as well) will share this was the beginning of the fossil powered human population boom - "sustainability of the world population" now requiring massive increases in energy production - thats how we got to the mess we have today. Wars over oil, Fukushima, ecological disasters small and large. etc.

Watt died on 19 August 1819. A unit of measurement of electrical and mechanical power - the watt - is named in his honour.
