How do you transport solar power tower energy to a building that is 4 kms away?
And is an area of 1 km^2 for a solar power tower enough to produce energy for five houses? can you make an approximation of how much it could supply?
If you want the heat energy, consider tracking mirrors at the site and solar collectors on the houses. If you want electric energy, that area is enough to support a traditional steam turbine, much more cost-effective than photovoltaic. That area is about 15 times the area that Solar One used to generate 10 megawatts in the Mohave Desert, so it could supply a theoretical maximum of 150 megawatts during peak sunshine. That’s probably enough to match the demand of about 25,000 homes. Best bet would be to feed it to the electric power grid.
