Black House

Congratulations to President-elect Trump. An Electoral College coup failed to materialize. So, in a couple of weeks, he will be President Trump. I wonder how long it takes until he rips the solar panels off the roof of the White House. That’s because one of the most popular posts of this blog was titled “Why … [Read more…]

Simple Hydro Energy Storage Concept
