Ah hA! You beat me to it. I was thinking of an optical mouse to sense direction too! Clever. But again, the only answer to solar economy is simply to get a Permit and a NET meter. Done Bob

Such a project is already developed and it's Open Source! http://openenergymonitor.org/ I was involved in this project in the very early stage, and contributed some knowledge about the inner workings of revenue-grade kilowatthour meters. At the time, I was dumping excess PV production into the bottom element of my water heater by detecting the rotation and speed of a mechanical (spinning disc type) kWh meter using an optical mouse. Direction and speed information was then fed to a servo-driven 60 ampere Variac autotransformer, which supplied the variable voltage to the H20 heater element. It successfully stripped 99% of the PV production over house demand every month for a couple of years before I obtained a net metering contract from my utility. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
