This is my prototype "Ram siphon" drainage pump. It runs on free, renewable energy (flowing water) and could perhaps be used to drain pits, goldmines =) , basements and bunkers. There's more information on my website at www.piimaa.net/ram
This is not my invention but I've never seen a working prototype or even proper plans (got the basic inspiration from Australian website some years a go). I call this pump "ram siphon" (somewhat misleading perhaps).
