Solar energy way cheaper than coal, available NOW

[azuredu]

It is a parabolic trough, a concentrating solar collector. I have made
a new design that divides its cost tenfold, and reduces its size for
homes and rooftops, without reducing its performance. That's it!

All the secrets are in this site: http://wims.unice.fr/xiao/solar/index.html

With this, you can already build an energy-independent off-grid home,
all by yourself, saving a lot from your energy bills, without ruining
your budget buying hyper-expensive solar equipments.

Commercial products will be available a little bit later.

Just do it!
