Good, if highly ironic, use of solar. It's not the greenest use, but is a good resource utilization due to being cheap to run and effectively using the indigenous resources in the area.
I hope other EOR sites located in sunny areas make use of this technology. It seems tailor-made for the Middle East.
Also, think of the desalination potential. That's why this technology needs to be scaled up and used more places. If it can make enough steam to extract oil, what about boiling enough drinking water for folks in sunny Florida or coastal Texas? They're going to run out of potable groundwater in the next 40-50 years, and it's not going to be pretty.
