The storage capacity is sized for daily consumption, not the yearly figure you quoted. And of course, this is one small project out of the hundreds of plants that will be needed to meet climate goals.

The biggest issue with solar right now is that the output varies over the course of the day, leaving other power plants to take up the load at night or during cloudy weather. The attached battery storage averages out the solar plant’s output, letting it be a useful contributor to the grid around the clock. There’s other benefits like grid stabilization and peak shaving, where the battery stores and releases oversupply from the rest of the grid, not just the attached solar panels.

But the pressure from the atmosphere applies to both sides of the sphincter, resulting in zero net pressure. Unless the suit actually does press against the outside of the sphincter like it does the rest of the body, I think OP’s concern about the suit squeezing you like a tube of toothpaste is valid.

Maybe the suit only applies a few PSI instead of the full 14.7, which it seems like one’s sphincters would be able to withstand.
