Re: The Involved vs. The Apathetic -- odds anyone?

I need an objective that is not ridiculously small but not so large that I'll never raise the funding.  There has to be an efficiency threshold for readily available solar/thermal components.

Can we design a machine shed (barn) for my brother's little golf course - straw bale - earth bermed - well insulated sort of thing, with a sloping south wall for your system.

Now, - how big do I build it and how much will it cost to put on a solar/thermal demo? 

Can we build something to supply home heating/electricity for a normal home during sunny periods with unused capacity pumping water to a higher potential or charging batteries for electric golf carts or grass cutters?

Do I need 10 friends with $2,000  or 49 with$1,000.
