We talk about being able to work off the grid but it is the Amish who
do so daily. Have any of you seen Simply Amish furniture?
http://www.simplyamish.com/ The guy who started the company was
raised Amish but no longer follows the faith strictly. He built a
company that has his fellow Amish building furniture on their farms
(no factories).
What is interesting is how they power their tools. First off they
tend to use air powered tools as the compressor does not need to run
continuously. One farmer has a bank of batteries recharged by wind
power. He batteries are set up like battery back up (UPS) for main
frame computers. Float charging with massive inverters (DC to AC).
Others use those propane fueled generators that you can buy at Lowes
or Home Depot for emergency power for your home (10kw to 100kw).
One fellow has a horse powered generator that has the horse yoked to
something that looks like a millstone and walks in a circle all day.
