NASA's biggest worry right now: What if something goes wrong with the Webb telescope?

That's not what's silly. What's silly is that there's no practical solution, "even theoretically". |

Of course, not for every outlet, so it's true that a new outlet might need to be installed in the garage. I thought the US had 110V in their outlets. Did thar change? Did you switch to 50Hz as well? U.S. homes receive their power off of a center tapped transformer which provides (nominally) 120 volts on each leg. Most outlets are wired between the center tap and one of the two legs, providing 120 V. Several outlets are commonly wired across the outside legs, providing 240 V. These are usually found in laundry areas (for electric dryers), in kitchens (for electric stoves and ovens), and in garages (for tools such as welders and compressors). It is simple enough to add 240 V outlets when needed for other purposes (for instance, I put a 50A 240 V outlet in my wife's studio for an electric kiln). (Houses typically have 200 amp service, but can opt for 400 amp without the power company needing to make any wiring changes.) |

If you regularly drive more than 300 miles, it simply means that the current generation of EVs isn't appropriate for your needs. For you there remains conventional gasoline engines, or hybrids systems. And it is quite certain that long range EV solutions will be developed over the next few years. Nothing that doesn't already exist is certain. I mean, we still don't have a cure for AIDS. Some things are certain enough. |

To those who aren't morons, we already have. The laws of physics aren't changing. But it doesn't matter. Your driving habits place you in a small minority of the driving market. Only a small minority *ever* take long road trips? I didn't say that. Yeah, you pretty much did. I note that you do not address a single one of the real obstacles I've mentioned. As I predicted. You will *never* do so, because you *know* I am right. You can rent a different kind of car. You can own two different kinds of cars. If you're willing to turn all poor people out into the street to starve to death, sure. There are tens of millions of people in the US who *can't* own two different kinds of cars, and would have no place to keep the secone one if they did. You will *never* address that, because you *know* I am right. You can be part of a shared car pool (that's going to be increasingly popular given the waste associated with exclusive car ownership). No, not you *can* be, rather, you *must* be. Which means you need to work and live within walking distance of other people in the pool. Which, again, puts millions of people out of work. Your brilliant plan seems to have a few flaws. You're one of them. -- Terry Austin Vacation photos from Iceland: https://plus.google.com/u/0/collection/QaXQkB "Terry Austin: like the polio vaccine, only with more asshole." -- David Bilek Jesus forgives sinners, not criminals. Most of this is pointless, Yes, rehashing an argument that Chris has already lost is. So is trying to hijack the thread into a completely different discussion. -- Terry Austin Vacation photos from Iceland: https://plus.google.com/u/0/collection/QaXQkB "Terry Austin: like the polio vaccine, only with more asshole." -- David Bilek Jesus forgives sinners, not criminals. |

Well, it is true that there are such things as superconductors... I thought he was still referring to the situation of these apartment dwellers, not the laws of physics, due to the context. Even with a supercondcutor (and remember, "room temprature" superconductors still require pretty extreme cooling), you're still dealing with amounts of electricity that are dangerous for untrained idiots to handle. And home charging stations that cost more than the car are not a solution on a road trip to Vegas. But Chris won't *ever* address any of that, because he *knows* I'm right. -- Terry Austin Vacation photos from Iceland: https://plus.google.com/u/0/collection/QaXQkB "Terry Austin: like the polio vaccine, only with more asshole." -- David Bilek Jesus forgives sinners, not criminals. |
