I'm excited about the solar work you're doing.
Just by way of introduction, I'm an accountant from Sydney,
Australia. I spent a lot of time the last couple of years looking
into & experimenting with small solar thermal systems. I basically
went through the kind of steps you did experimenting with parabolic
troughs & Mylar & running into the same problems you did. I think
glass mirrors are definitely the way to go along with the linear
fresnel arrangement. I love your use of flat mirrors & your receiver
It's a refreshing change to see someone who is focussed on the
financial viability of solar thermal before getting carried away with
the technology. I think you're performance numbers are for the most
part pretty realistic. I did some financial & performance modeling
for some of my experiments with evacuated tube systems. I pumped
your system's numbers into it. This is for a CHP residential
application. Thought you might like to see the results. You can
download the excel sheet here: http://www.onlineaccountingservices.com.au/solar/SolarTurbine.xls
Note in particular the seasonal graph. Here is where one of the main
problems with solar thermal manifests - there is a mismatch between
supply & demand.
Anyway. Do you have any members in Australia? I might like to be
involved in some way if you are looking for help.
