Solar has overtaken gas and wind as biggest source of new US power • Bloomberg
Chris Martin:
<p>Despite tariffs that President Trump imposed on imported panels, the US installed more solar energy than any other source of electricity in the first quarter.

Developers installed 2.5 gigawatts of solar in the first quarter, up 13% from a year earlier, according to a report Tuesday from the Solar Energy Industries Association and GTM Research. That accounted for 55% of all new generation, with solar panels beating new wind and natural gas turbines for a second straight quarter.

The growth came even as tariffs on imported panels threatened to increase costs for developers. Giant fields of solar panels led the growth as community solar projects owned by homeowners and businesses took off. Total installations this year are expected to be 10.8 gigawatts, or about the same as last year, according to GTM. By 2023, annual installations should reach more than 14 gigawatts.</p>


Solar is unstoppable; the price of making panels keeps falling, and it's additive - you don't have to tear down old installations to put new ones in. And penetration of panels is at a tiny percentage of the potential.

Mining coal is a mug's game: expensive, dangerous, polluting. Speaking of which...

SILSTORE
Very high temperature (up to 1400C) molten silicon thermal energy storage. The kicker seems to be using concentrated solar power to melt, and a thermophotovoltaic system to recover power rather than a brayton cycle turbine using an intermediary fluid.

StratoSolar Precedent
Interesting precedent paper in the early days of photovoltaics, describing a system very similar to StaroSolar's floating PV array.
