Actually I saw in popular mechanics that the new thing is a type of solar funnel. Lots & lots of solar panels that generate power, that also create a greenhouse effect under the canopy of them. That feeds all the rising air into a central chimney looking structure filled with turbines. Smaller footprint than your typical solar or wind farm, much higher power generation, and it works even if it's not windy. Not as effective in colder climates though iirc.
