	Now we take the step of technological [[recursion]] on mirror fabrication, structure, collector and valving, steam engine components, and generator head components. This allows cost reduction down to the cost of materials plus labor, where the materials now are metal and glass.		Now we take the step of technological [[recursion]] on mirror fabrication, structure, collector and valving, steam engine components, and generator head components. This allows cost reduction down to the cost of materials plus labor, where the materials now are metal and glass.

	Metal can be cast to all necessary parts, and glass can be recycled from the waste steam. Feedstocks for these are about 10 cents per pound - or at least 10 times less expensive than the finished product. Thus, if one excludes labor, the price of the solar power generator becomes less than $300, under the assumption that [[Community Supported Manufacturing]] (CSM) is utilized. If one includes the labor, then the basic formula of $1000 worth generation for a human-day (see [http://~~openfarmtech~~.org~~/weblog~~/?p=487 Factor e Farm Distillation on Personal Fabrication]) of labor is utilized - assuming that the producer captures the full worth of their labor. The labor cost of this value is $25 per hour as a reasonable hourly rate in absence of overhead costs, where the latter assumes an off-grid production facility. One day's cost of this labor is $200, or a factor of 5 less than the value generated. What this indicates is that the general formula for cost structure of CSM product is 5-fold reduction of price by any recursion step.

	This analysis begins by examining the solar energy-capturing substrate in both systems. For photovoltaics, that is the cost of solar cells – which are $40/sq foot for the lowest cost option. (ref 5) For STC systems, that is high-iron glass mirrors – which is $2/sq foot. (ref 6) We are assuming an overall system cycle efficiency of 10% for PV, and 7.5% for the Solar Turbine – such that we are relying on proven performances with respect to the STC concept.

(ref 6) We are assuming an overall system cycle efficiency of 10% for PV, and 7.5% for the Solar Turbine – such that we are relying on proven performances with respect to the STC concept.

	This analysis and implementation procedure invoked in this study is based entirely upon proven techniques utilized for energy capture and conversion. Namely, we are using a simple, single-piston steam engine as the energy conversion device. Single-piston team engines that existed since the turn of the 19th century have demonstrated overall cycle efficiencies of 26%. (see p. 317 in [http://books.google.com/books?hl=en&id=uzoJbLVkUHUC&dq=steam+engine+principles+and+practice&printsec=frontcover&source=web&ots=hzdKZRs6yz&sig=Tb5c3HglGpb-FXn5Zk8qlwNhm6E&sa=X&oi=book_result&resnum=2&ct=result#PPA411,M1]) We are basing our analysis upon such proven results – including a 50% solar reflector/collector efficiency – to arrive at an overall 7.5% efficiency mentioned above.

In particular, we are relying on creating an 18% thermal efficiency steam engine, which for the temperature conditions in question, is an empirically proven result.

	It should be noted that even with the low, 5% efficiency, our overall STC system design yields factor 10 price improvements compared to PV. We are pointing out that simple, proven techniques are already sufficient to produce the next energy evolution – towards a decentralized society enjoying a high quality of life. Therefore, this proposition should be considered by any change agent.
