Watermotor - Simple Mechanical Drive
High energy efficiency means that the quantity of water necessary for operation and cost of installation is greatly reduced, while on the other hand the number of actual locations where waterpower on this scale is available increases exponentially. In effect, every small fast-flowing stream becomes an important local energy resource, perhaps in many cases the only practical one available. In the world's hilly and mountainous areas there are often few roads and even fewer electric power-lines. While frequently rich in small scale water-power resources, the people are poor.
The Watermotor is a practical means of utilizing one of the easiest to use and most efficient sources of natural energy.

Installing Solar at Woodhenge.org
Each frame has a small combiner box connecting the 4 panels with 12 gauge cable to a 10 gauge uplink to the master combiner box. The master combiner uplinks to the house with 6 gauge. See pics at http://ph.groups.yahoo.com/group/12VDC_Power/photos/browse/5156?c=
They bought a 40' shipping container to put belongings in while the house is being finished, so we put a temporary pv system on that as well for internal lighting.
We go back next weekend to fix the wind turbine and install some ground lines for the panels.
