Wind turbines. Enough to supply about 10.000 kWh or 10 MWh annually. "We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It's a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary." - MUCH cheaper. Just one foot. Designed to give to higher windspeeds, possibly by using a semi-flexible foot.
HHO Generator - Water to Fuel Converter
Splicing water bottles. For storing compressed oxygen to be used with ethanol/aluminium powder gas jet burner/furnace. Either this or a used propane tank.

Primitive steam engine provides work, thus freeing up workers and reducing need for draft animals. The goal of any society is to minimize the number of people occupied with manual labour and maximizing the number of skilled craftsmen/artisans, scientists, artists etc. Brazilian Bbq, Economic Efficiency, Single Oven, Rocket Stoves, Electrical Appliances, Steam Engine, Energy Sources, Scientists

Hydraulic robot arm. Replace the manual input with (electric motors, threaded rods and polarity reversing switches) and you can do it all using buttons, not levers (this allows greater distance between robot and operator). Mechanical advantage would have to be derived from the gear ratio. This would allow much more precise work too. Achieving a 360-degree rotation from linear movement: 2 gears where half rotation from big gear = 1 full rotation of small gear.

ETHANOL gas jet burner. A can with small hole in top & with a syringe needle placed over the hole. Can is filled with ethanol/veggie oil & placed on hot coals. Ethanol/oil vapors then ignited. Can is insulated. Smaller syringe inside bigger one delivers oxygen (preheated). Let air inside when can is cooling down to prevent implosion & let fuel "boil" for some time before igniting it to prevent explosion. For welding: a stoichiometric fuel/oxygen mix. For cutting metal: "too much oxygen" mix. Brazing, Syringe, Soldering, All Brands, Welding, Metal Working, Insulated, Novelty Lamp

Homemade bench vise, using a bolt and matching nut. A vise requires two hard surfaces. One surface can be installed on top of the nut, whereas the other surface attaches to the bolt further away, specifically by having the bolt go through a drilled hole in the "surface" and a washer on the other side to allow the bolt free movement/rotation while simultaneously making that rotation force this 2nd surface closer to the first one on top of the nut. Bolt can be a lot shorter and thinner. Homemade Bench, Nut Bolt, Bench Vise, The Other Side, Ham Holder, Thinner, Washer, Closer
