The conversion over to EVs got me thinking about energy independence for some, distributed renewable generation and storage. You can't make your own gasoline, but you can make your own electricity, by wind, solar or even small scale hydro, if you have the circumstances and soon you may have the economical means to store it.
If you drive an EV, you can drive it for free, if you live in a more rural setting. This is a carbon neutral way to generate electricity using wood gas and if you burn wood for heat or to supplement it this might be something to look at. This one is made from FEMA plans, free online and can use wood chips as well as pellets. If you have a wood chipper you can turn branches and brush into fuel. From what I've been reading something like this could generate up to 20 kW easily, so for every hour you run it your home battery bank or EV gets 20kWh of charge. If you used it to charge an EV that got 5km/kWh, you would get 100 km of range in that hour. A farmer with a half ton with a 1600km range could use a variety of biomass and agricultural waste as fuel and with a battery bank at home would have a lot of flexibility, a 12 hour overnight charge would give him 1000km of range perhaps.
This fuel flexibility from renewables and wood gas generators could slash the energy costs of many farmers, if their equipment was electrically powered with a new generation of cheap better batteries. Fuel costs can be as much as 30% of production costs. They can also make a gasometer to store gas too, such a system would likely be used when the wind doesn't blow, a 50 or 100kW wind turbine might be their best option. Not paying for fuel would mean pocketing a considerable amount of money for many farmers and make them independent from energy prices.
