<DIV><FONT face=Arial>a place just a little closer to you is ALT Fabrication in
Argyle. That's just in Denton County off SH377.</FONT></DIV>
<DIV><FONT face=Arial>It's where I found ground plates, and pretty much anything
else made of copper. </FONT></DIV>

often, and reduce both battery bank and inverter requirements.<BR><BR>The
market (arguably free on so many levels, and obviously not on so many
others) can address this using current technology. System sizing
math not has changed fundamentally in several decades but we are getting
closer to those fundamental limits.<BR><BR>Industrial systems are a bit
ahead of the consumer market in some areas but behind in others. As
one very basic example, Turbocor's maglev compressor has created a few waves
in the commercial and light industrial sector but I fully expect some
fascinating trickle-down benefits over next few years <<A
