Seems like a total non-problem. It doesn't matter if it captures 4%, 99% or 0.000001% of the solar energy. All that matters is the total cost of the fuel at the end is in the same ballpark as current fuel prices. This depends on the plant being economic to build and to run. For example, if you can design a cheaper version of the plant that captures only 1% of the energy of the sun, you just need 4 times as many mirrors (and the land to put them on). That might cost more than the savings on the cheaper plant design, or it might cost less. It might depend on where you are building the plant and what the land values are there and how much sunshine the area gets.
