I am looking to form a group or Guild rather for tinkerers... a tinkerers guild. For the purpose of working together design build and compare different renewable energy projects for our homes. Ideas include solar thermal indoor and outdoor air heaters, water heaters, wind turbine, fresnel lens metal casting, parabolic dish steam generation, woodgas, hydro, electrolysis and hydrogen uses, biogas. The list goes on. If you are into this call me at show contact info
