This blog post is around seven or eight years overdue. Anyway, I had been musing about energy grids at the time and thinking about things like long-distance alternating current (AC) power transmission, the rise of solar panels, and electronics. I figured in 15-20 years (so about 7-12 years from now), we’d start seeing direct current (DC) power being more available from the wall. Before that can happen, people need a supply of DC power and devices that use DC power.
