I was searching craigslist.org today for a satellite dish that I could
convert into a solar concentrator for water heating. Lo and behold
there's one for sale for $0 about 70 miles from me in the SF Bay
Area. The price is right, but hefting a few hundred pounds of steel
onto the roof of my little Golf gave me pause for thought. What are
peoples experiences in converting satellite dishes into solar

I would be interested to know, what temperature you can get at the focal
point of the satellite dish.

I am slowly grinding my way this end. You will need to consider the
effects of a failure of the tracking system (potential
overheat/boil/explode). You will also need to consider upping the
tracking to "dual axis" capability as the dish will only be perfect for
a few days per year, presuming it is a typical polar axis tracking unit.
I am using a second (salvaged) actuator to adjust the elevation on my
Being a computer geek I am going to use a (linux) PC to manage the
tracking but there are many options for this.

Great website! I look forward to seeing realtime data streaming in
from your dish to your website.
