    That is a poor quality source. A lot of "hand wavy" arguments with little to no citations.

  That looks interesting, I hope the company succeeds and we see more of this. Side note, the article has a comment about peak summer power usage that made me laugh out loud: > For example, Mumbai hits peak consumption in the summer when air conditioners are on full blast, whereas London peaks in winters because of household heating. Ideally, energy captured in one season could be stored for months during low-use seasons, and then deployed later in the high-use seasons. It seems hilarious to talk about storing power to run AC in order to solve an excess of heat problem. I honestly feel bad for people who die in heat waves in large cities, but it seems pretty absurd that we’re not already running AC cooling on solar like everywhere.
