Conclusion and practical solution
After reading through many patents and websites the following seems to be the solution: Use arrays of 1x1m heliostats as per http://www.practicalsolar.com/, but instead of using his flat mirrors used bended plastic mirrors as per http://www.solarfire.org/tech/helios/helios.html or even better the SoharaDotOrg concept.

A square piece of plastic has cross sectional ribs glued from corner to corner in a X shape. It is glued at the center. Near the edges on the rib, a threaded bolt is screwed through to generate a curved parabola shape of of the square mirror. http://www.solarfire.org/tech/helios/helios.html removed the photos and explanation of how they micro adjust a plastic reflective covered mirror in parabola shape with four bolts and two ribs. The ribs are glued at the center of the plastic mirror with the 4 edges not glued, allowing the ribs to bend inwards at the edges as the 4 bolts are tightened. As time allows a picture of how this is done will be uploaded. Solarfire.org should consider placing back this crucial piece of information on their site, it is an extremely cost effective engineering innovation. The plastic mirror is covered with http://www.reflectechsolar.com/pricing.html.

Place the SoharaDotOrg on residential roofs, focusing the light on water cooled PV cells. PV cells combined with concentrated sunlight are more efficient than StirlingEngine. Stirling Engines are four times as efficient as unconcentrated PV cells, but won't work with hazy weather, where PV cells will still operate. After sunset Stirling engines are used to generate electricity from hot oil as per Residential water heating with Fresnel lens.

The http://www.practicalsolar.com/ heliostat has 8 mirros the 9th center mirror is removed for a clamp. The mirror steering electronics design are from http://www.redrok.com/led3xassm.htm.


 * The heliostats with bended square mirrors inside.
 * 2cm air gaps between individual mirrors to reduce wind loading.
 * Much less torque and motor size needed to focus helio stat mirrors.
 * Focus an array of heliostats onto a parallel FresnelLens which in turn channels the energy into a fiber cable.
 * A collection of 8 mirrors are steered by the drivers and not every single mirror needs to be manipulated.

2-5kW Stirling engine
* http://sites.google.com/site/scarboroughsite/Home/HomemadePower/distribute-power Ques:A big challenge for this idea is the availability of a robust, cost effective, lightweight Stirling cycle engine in the 2-to-5kW range designed for use with solar heating. While there is a fair amount of information on the web about the cycle and history, these engines are specialized components and it's almost impossible to find commercially available examples. It seems as though you have to build one yourself if you want one. Designing and building a Stirling cycle engine for this application is no simple feat! For maximum efficiency you need to place the engine/generator combo at the prime focus of a parabolic reflector. This demands lightweight construction. Lightness and compactness require a high cycle efficiency, and this in turn requires a large temperature difference between the hot end and the cool end plus an effective regenerator to transfer heat between the compression and expansion processes. This has got to be difficult, otherwise why are they so hard to find?

Answ: Use parabolic troughs or fresnel lenses to heat up oil in a thermal battery. Pump the hot oil around the stirling engine, it thus won't need to be focused at the focul point of a parabolic lens.

FiberCell, a Winston-Salem spinoff of the nanotechnology center, has already licensed the technology for commercialization and has successfully fabricated lightweight and flexible solar-cell modules using inexpensive roll-to-roll and spray-on techniques.

Reflectech
Reflectech produces a reflective material very close to the efficiency of mirror, that is covered over any object to form a reflective surfaces such as a parabolic dish. Thus we can use scrap material, compressed wood, crushed glass to form parabolic troughs etc and then cove it with this reflective material. Without reflectech a DIY approach to energy production won't be feasible. Cover a diy SolarLinks with Reflectech at around $22 per square meter.

ReflecTech® Mirror Film is the key design-driving innovation in the award-winning SkyTrough® parabolic trough solar concentrator. Both ReflecTech® Mirror Film and SkyTrough™ were developed through cooperative research with the U.S. National Renewable Energy Laboratory. SkyTrakker™ provides the local electronics that control and direct a trough’s movement by determining the optimal position for the collector based on calculating the sun’s position. The SkyTrakker™ represents a step-change in features, reliability and life-cycle costs of control units for parabolic trough power plants.
 * http://www.skyfuel.com/#/OUR%20PRODUCTS/

SkyTrakker™ is a critical component of SkyFuel’s product design and it is also available to the Concentrated Solar Power (CSP) industry for use in parabolic trough projects.

SkyFuel, in partnership with the Helac Corporation, have combined the SkyTrakker™ with a customized L30 helical, hydraulic rotary actuator to make the OnSun™ tracking, control and drive system.

Innovative SkyTrakker™ system features include:

• Advanced Health Monitoring – Capability to monitor and diagnose the solar collector performance and drive system operation

• Green Power Consumption – Reduced parasitic losses; half the power usage of prior generation control systems

• Variable Frequency Drive Motor – Controls the startup of the hydraulic pump motor, limits inrush current, allows for the most precise sun tracking and reduces electricity consumption.

• Flexible Communications – Network wired (RS-485) and/or wireless (2.4GHz RF) and Local PC control (USB).

• Flexible Electrical Power Inputs - Accepts from 110VAC to 220VAC single or three-phase.

• Easy Installation – The entire system is comprised of only two major elements for quick mounting and connection.

The combination of these features provide a trouble-free parabolic trough sun tracking system resulting in reduced operating costs and greater power production.

Thermal battery powering Stirling engine
The core innovative technology behind the success of the WhisperGen™ heat and power system is a Stirling external combustion engine. The four cylinder Stirling WhisperGen™ heat and power system, first released commercially in 1998, produces electricity and hot water suitable for household use or space heating. A patented mechanism, the Wobble Yoke, transfers the vertical motion of the pistons to the rotary motion of the alternator. The DC WhisperGen works well in conjunction with other forms of electrical or heating generation including solar heating, solar (Photo Voltaic), wind, another generator, or boiler.
 * http://www.whispergen.com/main/technology/
 * http://www.whispergen.com/content/library/Don_Clucas_Stirling_engine_generator_development.pdf

The heat to the engine is provided by a burner. Various burners, developed by Whisper Tech Limited specifically for the WhisperGen™ heat and power system, allow different models to operate on specific fuels including diesel, kerosene and natural gas.

http://www.volpower.co.nz/wawcs0131756/ln-whispergen.html. The Whisper gen seems to be the only commercial available Stirling engine and only in New Zealand. Buy the machine, strip it apart and scan every nut and bolt with a 3D-laser scanner(accurate to 0.001mm) upload the files in Autocad format together with the patent and publish on the Internet. Increase the size the stirling engine to 500Watt, string 20 of these in parallel, combined with power electronics for a single AC wave, which in turn is converted into 3-phase AC to power agriculture pumps or SA won' t have food in 5years because farmers can't pay the rates.

Thermal batteries maintain their heat energy through the night. This allows a StirlingEngine to provide 24hours of electricity. One cubic meter of a container containing glass beads and hot oil provides 100Kwhours of thermal energy. MoltenSalt is another option. In places where space is an issue and FresnelLens can't be used this is a solution. Any open piece of field as close as possible to the residence is used to setup solar array heliostats, Fresnel, parabolic or troughs to heat up oil to 300Cdegrees. The container is hoisted onto a truck and just like a milk truck of old stops by every home to swap out the oil containers(cold, hot) adjacent to the wall. The hot oil is used to power a StirlingEngine for home electricity generation. The cold oil pumped back into a second container which is removed by the truck to be "recharged" back to 100Kwatt by the sun. To reduce costs a community should purchase their own truck etc.

Or install the http://www.svvti.com/about.htm solar through design on the roof and pump the oil from trough to trough if space is at a premium. The industrial scale 10Mwatt commercial long range trough designs are for turbines because 3Mwatt Stirling engines can't be made. Most articles on solar energy are biased towards large scale commercial designs using turbines. But for small scale 100watt - 10kwatt generation heating up oil to power 20 StirlingEngines in parallel would be very easy to do.

 * http://tech.groups.yahoo.com/group/sesusa/

The realisation of that process can be found at the Fast Track page of the Communicable Insight website created by Dr. Allan J. Organ author of several seminal books about the Stirling engine. We are now discussing the construction of engines using this chart based design process. We are NOT discussing the process itself.

If your pursuit of an engine can be satisfied with a kinematic air/Nitrogen or Hydrogen charged engine which has the GPU-3 as the prototype, then you are in the right place.
 * http://web.me.com/allan.j.o/Communicable_Insight/FastTrack.html

There are numerous heat engine cycles of a similar nature to the Stirling process. Typically these are called “Hot Air Engines” of which a subset of those are classified as LTD Stirling engines (LTD = Low Temperature Differential). If this is your area of interest, you are invited to join the HotAirEngineSociety (HAES) list at YahooGroups as a place to start ( http://yahoogroups.com/group/HotAirEngineSociety).

Rick metioned it, and I repeat it now. The APAIR.Bells layout can mimic the gas-phasing relations common in Alpha's but in a pure Beta engine. This includes Delta P what is related to a high Delta T. What most did not read in the document is that it can  easely be configured as any Beta type, ofcourse its a Beta. The drive-train proposed on the Allan.O.J site is the one mentioned in the APAIR.Bells document (page 3 end of section 3.1). U.S. patent 4,546,663 Oct. 15, 1985; Drive linkage for Stirling cycle and other machines James G. Wood, Sunpower INC. It lacks the fine tuning of the lateral deviations at point T Zig, Rick and me came up with. At point S the motion is a simple arc

 * http://www.sesusa.org/steele/steele.htm
 * http://www.stirlingsteele.com/ Plans for building Stirling engine

In the Stirling-Steele engine, four gamma type Stirlings are daisy chained together. This is done by driving the displacers via linear drive rods which are attached to the top of power pistons. The rods pass thru a sealed bulkhead and the displacer cylinders are ported to power piston cylinders that are phased behind them 90 degrees. This allows an engine that only requires one crank throw per piston where other types of Stirlings require two. Fewer crankcase penetrations along with a simpler crank permit for a more cost effective engine to manufacture. Building four cylinder engines instead of single cylinder units has several strong advantages such as easy starting, good balance, smooth running even at very low speeds, increased heater and cooler surface area and good low end torque. As an external combustion engine, the Stirling-Steele engine can easily meet the EPA standards for carbon monoxide and hydrocarbon emissions. Since it is a closed cycle device, it runs very quietly without the need of a muffler.

The New Steele Double-Cam Stirling Engine. The new double cam drive is a very versatile and cost effective answer to multi cylinder beta type Stirlings. Beta type Stirlings with their higher compression ratios have long be thought to be the most hopeful Stirling for integrating into our energy hungry world. Now with this new Stirling drive it is possible to group or cluster multiple beta type Stirlings together to provide compact cost effective Stirling power producing engines or heat pumps for real world applications. Plans for this engine and finished engines based on this design are not available for sale however the US Patent covering this design improvement is available for license..

Question assumptions
http://www.stirlingengine.com/faq/one?scope=public&faq_id=1#9 "....Q: Where can I get a 5 to 25 kW Stirling engine for my house, car, boat, etc. that will run on any fuel from cow chips to sunshine and be price competitive with a Honda generator of the same capacity?

While it would be very nice if such an engine existed at a price per kW that is competitive with gasoline or diesel engines, that probably isn't realistic at first. Gasoline and diesel generators are manufactured by the millions. When a 5 to 25 kW Stirling engine design first reaches the market it will initially be manufactured in much lower quantities and so undoubtedly will cost more per kW than competitive gasoline and diesel engines....."

Which is true but the author is assuming that you need to build one huge 5kw engine. You don't, multiple 500Watt engines AC wave outputs can be combined into a single AC wave with appropriate IGBT switching technology. For 10kw 22 engines would be needed with the construction costs much lower than it would have been for four 5kw engines.

The deal also includes the acquisition of Stirling Cycles, a company developing Stirling engine technology, from Idealab for an undisclosed sum, and which has also been working on the Stirling process for years.

Power Play Energy, LLC based in New Canaan, Connecticut, is a privately-held private equity firm which owns alternative energy-related intellectual property and assets. And as each of these types of companies fragments hundreds of Stirling patents, the Stirling engine can't be commercially produced at reasonable cost because each patent holder wants royalties. We hack the patents and build ourselves via fronts.

Infinia Corporation, a Kennewick, Washington-based company, today announced that it has closed a $50 million Series B round of financing.The funds will be used to support the commerical launch of the company's Infinia Solar System product, which J.D. Sitton, Infinia's President and CEO, states, "[W]ill change the game in the solar power generation market." The Infinia Solar System combines Infinia’s free-piston Stirling engine with a dish-style solar concentrator to produce three kilowatts of grid-quality electric power. Infinia expects to start manufacturing and selling this product later in 2008.

Our inflated, balloon-shaped concentrators are key to Cool Earth's innovative design. Each 8-foot-diameter concentrator is made of plastic film—the same kind of plastic film used to bag potato chips, pretzels, and so on—with a transparent upper hemisphere and a reflective lower hemisphere. When inflated with air, the concentrator naturally forms a shape that focuses or concentrates sunlight onto a PV cell placed at the focal point. This means we need fewer cells to produce a lot more electricity. In fact, a single cell in our concentrator generates about 300 to 400 times the electricity of a cell without a concentrator.

Solar ring
http://www.svvti.com/about.htm ''Lens replaces Fresnel and trough designs. '' The Ring-Array Concentrator (RAC) is an ultra-powerful optical lens based on an array of nested ring reflectors. This patented design is completely free from the light-dispersion effects of conventional refractive lenses which allows for obtaining much higher efficiencies and concentrations for a broad range of electromagnetic energy spectrum. RAC forms a high-power beam on its rear side which can be ideal for many solar solar applications including high-concentration PV modules, electric generators based on Stirling heat engines, high-heat furnaces, hydrogen production, material processing, etc.

They claim it was patented, but the patent can't be found yet. There was a similar patent using rings but it expired in 2000. The rings were level, in the svvti.com design the rings rise up gradually.

Green power science
Non-patentable Stirling engines($285 - 40watt), which can easily be copied and reproduced with our own lathes and CNC machines. [url]http://www.greenpowerscience.com/SHOPHOME.html[/url] 40 to 500watt engine with parabolic and fresnel with youtube video. Multiple engines AC outputs are combined via IGBT, Mosfet etc. for a single large supply to power agriculture pumps, Fridges, air conditioners etc. Switching losses will be an issue, thus probably more viable for farms and small holdings, unless installed on flat roofs. Even 3.7kwatt can be built but at this size it gets expensive. Smaller 500Watt, each with its own heliostat, parabolic , Fresnel or Compound parabolic concentrator is used.

The whole issue is : build it yourself or create a community fund and buy the lathes etc. to crank out these machines. It can't be commercially reproduced at a reasonable cost. Thankfully there is nothing complicated about a generic Stirling engine.

A robust, low-maintenance and weather independent 12V or 24V heat and power system, the WhisperGen™ heat and power system is ideal for supplying remote automated sites or for use in environmentally sensitive areas…even in the most remote location. CURRENTLY BEING TRIALLED: The WhisperGen™ automated power station (APS) is an integrated, transportable 'plug and play' system that is fully customisable for applications that require independent, on-demand heat and power. Automatically and quietly manages your batteries and your hot water, starting and stopping without the need for human intervention. The DC WhisperGen is a 70Amph (12V) or 35Amph (24V) battery charger that also produces 5.5kW of heat energy for hot water and space heating. This hot water can be used as part of your heating requirement and also to heat your water for domestic purposes (enough energy to heat 300 litres within 2.5 hours). At maximum output, diesl consumption is only 0.75litres per our. Conversion of fuel to electricity and heat energy is greater than 90% when charging and heating, which also means that the DC WhisperGen produces no visible exhaust fumes and no obvious smell even when running at full capacity. The DC WhisperGen works well in conjunction with other forms of electrical or heating generation including solar heating, solar (Photo Voltaic), wind, another generator, or boiler. Typical applications for the DC WhisperGen are; marine, off grid, emergency vehicles and mobile homes. Lightweight, compact, smart and very quiet.
