Farmers have a lot of land – including rivers. If you drill down 10 meters to a mantel pocket by the side of a river, you get unlimited steam. You pass through a Dyson dry cleaner, to remove all heavy metals – included gold and platinum dust.
You now pass the steam through a steam turbine – then vent the steam to above a river – where it cools and falls as water.
Alternatively, condense ti to get at pure free water.
A we get 20kW of power – so we sell 10kW. 300,000 UK pounds a year from the national grid: that's right – the grid PAYS YOIU.
So free power and water. I have no links to farms.
