Charles Shults III combines solar hot water panels with a large fresnel lens to flash the hot water to steam, which runs a turbine to generate 6 kW of electricity, with hot water left over, which is recycled through the system. The system is expected to cost around $6,000 - $8,000 USD (targeting $1/Watt), with an ROI of 3-5 years.
Shults is in process of commercializing the system, with expected roll-out between Q2, 2008 and Q1, 2009. The concept is simple enough, and the components ubiquitous enough, that a competent do-it-yourselfer could construct one for himself.
: "This is going to make solar affordable for everyone." -- Charles Shults III
On the down side, Dr. Richard P. George, NEC, points out that the regulations on steam generator systems will make this take much more time, require much more engineering, exact far more legal expenses, and require far more testing and proving than what Shults might anticipate. (See his Talk:Directory:Charles Shults' Fresnel Solar Design, along with Shults' Talk:Directory:Charles Shults' Fresnel Solar Design.) But as a DIY project, such commercialization prerequisites are irrelevant.
A company and site specific to this technology is pending.

Solar Power Break-Through - Charles Shults shows us how he can make 6 kw Solar Systems for a fraction of today's PV solar panel costs. Power your home & electric car for $6,000 instead of over $50,000 for PV systems! (YouTube August 07, 2007)

Intense Solar Power - Charles Shults uses a beam of concentrated sunlight to melt a brick. The fresnel lens concentrates 1.2 kW in one square centimeter. Filmed at Angel's Nest, Taos, New Mexico, USA. (YouTube January 15, 2008)
Standard solar hot water panels heat water to 160-180 degrees F (via heat exchanger as a non-freezing solution circulates through the panels themselves). That water is then passed through the focal point of the fresnel lens, which captures around a kilowatt's worth of energy, flashing the hot water into steam at high pressure, which drives an electric generator. Hot water, just below the boiling point, emerges from the turbine. The hot water is recovered, going to a hot water storage tank or cistern.
The hot water panel array covers about 10 square meters of space.
For off-grid applications, the energy can be stored either in batteries or in a flywheel.
Five hours of operation a day would run a standard home.
Fresnel lenses can be made with common plastic molding equipment. In his prototype, Charles used one he got from a big-screen TV. He mounted the lens into an aluminum frame.
Low-cost plastic lenses can be gathered in huge arrays to produce industrial power generation. The lenses would be engineered to track the sun.
Presently data is being collected to determine how much sunlight is needed at a minimum to provide enough heat to flash the hot water to steam.
A 6 kW PV solar panel array would cost over $50,000, while this 6 kW system cost around $6,000 - $8,000 USD. The company is targeting a cost of $1/Watt.
In addition to electricity and heat, Shults also plans to make a fiber optic system available for conducting light into the home during the day.
For off-grid homes, this system would best be paired with other renewables such as wind power, to account for consecutive cloudy days.
PF Solar Panels are only 12-20% efficient, whereas this system is around 60% efficient.
The water is recycled through the system, not lost.
For each home powered by this system, that means 6-10 less cubic meters of water per day consumed by a power plant generating electricity for that home. http://www.newswise.com/articles/view/537228/?sc=dwhp
The fresnel lenses can also be used for:
Sterilizing drinking water
Shults says that his system would be ideal for space applications. He said that all the materials needed to build it could be found on the moon, for example (except for the water).
Patents will probably be filed on
the proprietary turbine designed for this system
an optical tracking system that Shults devised

Looking at this, I can't resist to wonder if the design could be improved using the Directory:Green Steam Engine. It could be attached to the generator and is very efficient, probably better than a turbine.

There was an error working with the wiki: Code:
Once you add lawyers, insurance, trained boiler operators, and regulators into the mix, the costs inflate substantially -- much like the ladders at Home Depot that cost $50 to make and $250 for the insurance. Many steam regulators will not allow these devices to run unattended without a trained steam boiler operator present when running. Add the labor component, and the good economics evaporate for home scale systems (for utility or MW scale systems the labor cost per watt is minimal). This is why Directory:Stirling Engines make more commercial sense for this application than a steam engine, despite their having substantially more technical challenges to manufacture."
The company launch will be announced at http://www.FreeWillPower.org
