The company's news page has an impressive quote from their CEO.
"eSolar's primary business goal is nothing short of making solar electricity for less than the price of coal, without subsidies. This is not only attainable, but will truly change the world."
That's a stark contrast to the coal industry's strategy. Even if the billions of dollars in government subsidies for clean coal projects ever produces a working carbon capture gassification plant, the energy it produces will likely cost more than new solar that's already on the market.
The company fact sheet brags that the unique PowerTower can be built quickly, produces energy at competitive rates, creates jobs, and can be built on small pieces of land. Although, 20 acres for 5MW of power seems like a large footprint to me.
I have no idea if this system is the best option if Springfield builds solar. But, I always like reading that there are many realistic options out there.
