Energy notes2

This section is a bit dated Sasecurity is the preferred solution

Heat to StirlingEngines is provided by any heat source such as MoltenSalt, Solar Energy, gas or coal.

See http://wims.unice.fr/xiao/solar/storage.html for the creation of a thermal battery via a hermetic heat resistant steel case, of whatever size and shape. Operating at a temperature range of 150°C-350°C, the storage capacity is usually 50-100kWh/m3. Thermal batteries maintain their heat energy through the night. This allows a StirlingEngine and WindEnergyto provide 24hours of electricity. MoltenSalt is another option. Setup Solar array heliostats, Fresnel, parabolic or troughs design from SolarLinks to heat up oil to 300Cdegrees.

''Any open piece of field as close as possible to the residences is used if the owner has no space for a FresnelLens from SolarLinks or don't wish to install throughs on his roof. Heat a large volume of synthetic oil using SolarLinks and store it in a huge vacuum sealed container on a truck. The truck drives out to each residence and like a "milk truck" pores out the hot 200degree oil into the container filled with glass as per Residential water heating with Fresnel lens. A second truck picks up the cold synthetic oil to reheat. ''

This hot oil or thermal energy stored as per the method from Residential water heating with Fresnel lens is used to generate hot water, cooking food and driving a heat-pump air conditioning system. Most domestic usage of electricity is for heat generation. It is more efficient to enable heat->heat as per http://wims.unice.fr/xiao/solar/storage.html than to go from heat->electricity->heat. The energy and switching losses over the Eskom grid is unacceptable for a heat only application.

In places where space is an issue install http://www.svvti.com/about.htm FresnelLens/ParabolicTrough on the roof. The industrial scale 10Mwatt commercial long range trough designs are for turbines because. The http://www.whispergen.com/main/technology/ has a 22% efficiency, while Eskom's turbines have a 15% efficiency. Double the energy is achieved with the same lump of coal in a StirlingEngine. During wet weather burn gas to power the engine. Estates for example could setup a 1/3 hecter StirlingEngine plant on an open field across them and connect hundreds of engines for electricity generation, desalination and hydrogen production. Sewage treatment is also done like this.

The Whispergen retails for $USD 22000 in New Zealand, but that is because of all the patent royalties that have to be paid, the actual mechanical linkages, wobble yokes etc, DIY will be a fraction of this. The weight of the engine(200kg) in metal should roughly indicate its true value when hacked and made ourselves.
