So there's this guy here who "informed" us at supper the other night that there's a company that, for $30,000, will convert a Prius into a pure EV that will go a thousand miles on a single charge. I told him this is not the case. The batteries alone for a thousand-mile EV would cost close to three hundred thousand dollars, and would probably be too heavy and too bulky to fit into a Prius even if you used the entire cargo space. He said he had read about it in a "reliable" magazine (but he could not remember which one!!!) so it was true. I'd have said more but he was getting this "won't this jerk shut up" look and starting to talk about something else to the person next to him. I mention this to draw attention to the truly phenominal level of ignorance of the general public as regards transportation options. Someone else asked, wasn't there a car that runs on oxygen? Where to begin with a question like that? Explain that all fuels need oxygen to burn, so oxygen is a part of the equation in any fuel-burning car, but the atmosphere is 21% oxygen, so it's not an issue? Or just hang your head in despair that there are people who don't even understand the basic chemistry of fire? With people like this, no wonder the public thinks that hydrogen fuel cells are a practical possibility, or that water-for-gas schemes are real. The world is populated by idiots. Time for lunch... The food here is fabulous!
