Competing Technologies in Concentrated Solar Power

Here’s an article that compares the two main competing technologies in concentrated solar power (CSP): linear Fresnel lenses vs. parabolic troughs.  The main issue, of course, is the cost of the reflectors themselves, as well as the apparatus whereby they track the sun as it moves across the sky. 

This reminds me of the work that has been done by my friends at Ahura Energy, whose breakthrough directly affects the cost associated with tracking the sun.   I’m hoping to round up an investor or two who will be interested in funding a few small pilot plants, each of which have power purchase agreement already in place; it’s a quite attractive proposition.
