Energy final

Work in progress, trying to come to some sort of practical solution to generate 10Kwh electricty for ten homes for a period of 7hours, 1Kwh each:

Heat up mineral oil or water to melt MoltenSalt at the veldt or plot using helio stat mirrors focused on a boiler. One cubic meter of MoltenSalt weighing one ton at 400degree C stores 600Kwh(much higher 2000KwH+) of thermal energy. The 12Kwh Engines2 at 12% heat to electricty conversion efficiency provides 72Kwh of electrical energy or 7.2Kwh over 10 hours. Thus ten homes can draw 1KwH electricity for 7.2 hours, sharing one 12Kwh Engines2 retailing for $9000 from Canada. At the turbine water is placed through a heat exchanger inside the MoltenSalt solution turning it into 150degree steam to drive a Engines2. A residential mini steamplant is constructed from the designs sold by Steam_Engines3. His steam engine won't be used though, the Engines2 is preferred using much less pressure and temperature.

One MoltenSalt cubic meter solution of 400degrees celcius are created with the Fresnel array mirror - SolarLinks, Redrok_solar_links, on an open small veldt or plot 20km away from the ten urban houses. One ton melted salt solution is transported with a 1 ton truck to the residents and off-loaded inside the house behind closed gates. The cold MoltenSalt from the previous day is uploaded to be recharged back to 600Kwh of thermal energy. Probably much more that 600KwH is possible with a ton of MoltenSalt. 24 hour operation is possible.

Purchase the Engines2 with a 9% bank lone:
 * $9000 x R7= R63000 + duties, shipping(R20000) => R83000
 * At 9% interest each of the ten homes would only pay R62,00 a month

Hoist a small 100kg boiler with molten salt to the focul point of a helio-stat mirror. On reaching 400 degrees C, swap out with another mini boiler. Load multiple boilers on a small truck and deliver to residents.

If the min-boiler is to large in diameter, hot spots could form where only the one side of the container heats up

to 400C. Insert a propellar to mix the solution. In the end whatever one would do to distribute the heat would be

obtained from a discussion with a consulting mechanical engineer.

Fit a container over the four pistons of the wobble yoke Whispergen StirlingEngine. Pump molten salts through this container. (See Solar Notes, first heat up synthetic oil via heat exchanger inside molten solt, then pump the oil over the stirling pistons.) This negates the need to focus the sun's rays on the Stirling engine itself, a difficult and cumbersome process. It is easier to melt salts in a container using Fresnel mirror array, remove it and pump this stored 400degree energy over the stirling pistons.
