When you just bought a bunch of gear hobs to cut gears to automate a mill to carve blades, and your making the gears so you can multiply the torque so that you can use smaller servos to draw less power. -And you still have to finish the building you built to put the machine into.
When you look around yourself as you type and see two solar panels you still have to mount, some linear slides, a couple spools of wire and a mini-milling machine, Every note on your fridge and door is held on with neodymium magnets. Oh and by the way, they make great 'no mar' mounts for picture frames on drywall if you can find a suitably located drywall nail or screw under the plaster to stick it to. Also, if you already new the preceding.
I'm not here yet I don't think, but when you have more in horsepower in electric motors than in internal combustion engines. --and you own three cars.
When a gust of wind takes a 'temporary' mount down on your roof and smashes your car window, -- and your more concerned about the turbine. (this is hypothetical of course)
When your idea of a great vacation is driving to Colorado to look at Turbines at the OtherPower 'Research and Developement' facility located in the Rockies.
When your girlfriend/wife/significant other thinks you are nuts because of RE and none of the above have come true yet. (warning sign)
When its 2AM on a Sunday Morning, you've just gotten home and you are responding to this post, or if you have Area 52 on your property.
Have Fun, Rich Hagen
