RE: [hreg] Earth Day 2002
- We were out of town last week end so did not see the event or the TV.
However during the past century, we built a 18-72 volt electrical motor and
speed control for a VW bug. We calculated that the solar panel to drive it
at 70 mph would be about 8' x 32'. We did not build the solar panels but
used batteries recharged from the powerline. The speed control for the wide
speed range was my thesis project and it can be very expensive. The wide
range speed control and the special motor are long gone to recycle and our
memory is slipping too.
The engineering societies still encourage colleges and universities to
participate in cross country competitions. Popular science magazines are a
fairly good reference for these activities. Their articles tend to be
spectacular (media) compared to the long hours and the grunt work required
but they have some pretty engaging text and good photos.
Slower speeds, reduced range, better batteries, and better choice of running
gear would improve the cost but it would still require significant funding.
We would be happy to share some experiences from the early 70s with anyone
who is interested and committed to a vehicle.
First estimate of cost for good, used, attractive, open running gear, DC
motor, simple speed control, battery and solar panel is about $5,000 plus
labor. We could proceed in steps with the chassis first, motor second, speed
control third, then battery and solar panel.
Just now we are working to convince the City of the Astros to invest in
fixed solar power for some of their facilities. Good things take time. Also
some things improve over time. Solar generation is a technology whose time
Please let me know when and where the hreg design team assembles.

Re: [hreg] Earth Day 2002Having been a RG reseller, Local Pro and stock holder in the past I think if more people knew what is going on with this company they would be less inclined to conduct business with them.Recently RG elected to sell out to a large corporation in Ohio. Some of the terms of that deal were that the wholesale program for regional dealers and Local Pros was eliminated, stockholders were compensated at a ten to one loss and Schaeffer got to keep the Solar Living Center as his own little non-profit toy. Not to mention the massive layoffs that occurred at RG when the catalog operations were shifted to Ohio.Real Goods is not the warm, fuzzy company that they have successfully managed to convince the general public they are. This is yet another cold, calculating corporation that does not hesitate to screw associates, employees and investors to achieve single minded objectives. To anyone who thinks this company is a Earth friendly, green, sustainable business I hope they soon understand this is not the case.SBT Designs

It is the ISL that puts on over 40 educational workshops every year, runs tours for students and energy professionals, and produces the 6th Annual SolFest, the nation's premier energy and sustainable living festival.
So far scheduled to speak are Roy McAlister, president of the American Hydrogen Association and Dave Foreman, founder of EarthFirst! and currently working on the "re-wilding" of the SouthWest. Paul Ray and Sherry Anderson, demographers extraordinaire who coined the term "cultural creatives", will be leading an interactive workshop on who we are as cultural creatives and where we are going. Many more great speakers are on the "not-yet-confirmed list.
Musically, the talent is beginning to line up and invitation letters have gone out to Bruce Cockburn, Crosby-Stills-Nash, Bonnie Raitt, Ben Harper, Keb Mo, Indigo Girls, and more - just who we land musically is yet to be determined. Mark your calendars for August 25th and 26th! We'll keep you updated on more news about the event in future issues of the Solar Times.
Enjoy the Spring!

I too read about that concert in California, but can't remember the
source. I think the concert was called Pig Fest, which may aid in
