I've put in a couple of small PV system in the last few years, and will put a good sized one in my new house. There are no subsidies, not for the panels, not for the electronics, not for the batteries. Unless you manufactured everything yourself, yes, the manufacturers were subsidized. But the real killer, the thing for which there simply isn't a vaiable solution, is energy transfer times. You can put enough gas into a car to travel 300+ miles in about three minutes. Not a problem, given that the vast majority of driving is under 50 miles, But not *all*, *always*. Ever hear of a vacation? with plenty of slow charge time between. For longer trips, there will be hybrids, exchangeable batteries, and other solutions. Hybrids are still using gasoline. Exchangable batters have the exact same problem: you need a dozen times as many charging stations to service the same number of vehicles per day, and a 30 MW power line coming to run them. "Other solutions" are vaporware. People need gas stations because they don't have gasoline at home or at work. And because they travel beyond the driving range of their vehicle. They do have power. But not enough to put 300+ miles of dirving into their car in three minutes. And, again, many people rent. There's no power by my parking spot, nor on the street. And with lots of cars on chargers, they become a major part of the storage system for a wind/solar supplied grid. There isn't a single car on the market today, nor any planned, that feed power back into the grid. Nor a charging station that would allow that. No, it's not a myth. Electric cars will soon be fine for a second vehicle... It's not really an issue, Only ify ou're so deluded that you are not longer interacting in the real world. as they're not going to have a choice. Tell that to Gray Davis. He messed with California's cars, and got handed his ass in a recall election. Electric is going to be the only game in town unless people want to pay a fortune for a specialty vehicle. Mighty tasty Kool-Aid you're smoking there, son. Battery technology does not utilize much in the way of rare earths. It does utilize ltihium, which has its own issues. Lithium is domestically produced. Not in sufficient quantities for 60 million cars a year. By orders of magnitude. Why would there be if we're not dependent upon foreign sources for materials? China is the biggest producer of rare earths. Which are used in battery production, and wich are absolutely required for the electronics needed for charging. No, they're not. Yeah, they are. Until a few years ago, they were the only commercial porducers. The only place rare earth elements are potentially involved is in the motors, and not necessarily there. And in any case, we can buy from China. China has already manipulated the market to protect domestic usage. You are, literally, hallucinating if you believe otherwise. It was quite newsworthy at the time. China has their own military to defend their own interests. They aren't a third world country that we need to maintain a military presence in as is the case with petroleum. That is precisely why they can get away with manipulating the market to protect their own interests. Not when you scale it up to the 60 million cars manufactured every year. (And there isn't enough lithium production to support that anyway.) It's always amusing to see people who lack imagination and ignore the fact that there has never been a new technology that didn't rapidly result in the creation of whatever it needed in the way of support. It's always amusing to see someone to ****ing stupid and delusional that they literally hallucinate the world they want to live in. They get so confused when reality bits them in the ass. Keep smoking that Kool-Aid, son. You're gonna need it. -- 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. |

And in any case, we can buy from China. For a while, recently, China decided to monkey with its rare earth exports to favor domestic users. This caused quite a worldwide panic. And the reopening of mines in the US. The panic was somewhat unwarranted. The minerals from which rare earth metals are extracted are widely available in many other countries. The only problem is that the only facilities that refined those ores were in China, because it was cheaper to do that there than anywhere else. And that it takes years to reopen mines and build refineries. So if China declined to export rare earth metals, we could make do with last years' smartphones for a while, and then make our own. And we could then enact tariffs to protect the investment in the replacement plants when China decided its ploy wasn't working and decided to undersell them. Like they did with solar panels, resulting in punitive tariffs imposed on their solar cells. Trade wars aren't good for anybody, but they're a lot worse for China than for the US. Very disruptive in the meantime, though. It was perhaps more legal to do what was done - point out that what China was doing violated trade agreements it had signed. But trade agreements that force countries to export raw materials instead of manufactured goods *are* inherently exploitive, so I couldn't whole-heartedly root for that. And there's still nowhere near enough lithium being produced for 60 million cars a year. -- 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. |

Never? I always thought that of 100 new technologies, 99 of them never catch on, and thus don't get what they need for support. The first thing electric cars need is electricity that isn't made from fossil fuels. If the electricity they use comes from a coal-fired generating plant, there is no benefit from a carbon point of view. There could still be a local environmental benefit for things like photochemical smog. The more centralized the energy production, the easier and more effective (and cost efficient) the pollution controls can be. And coal is disappearing in electrical generation. That isn't the fatal flaw in electric cars. If *that* were to happen, then we would be reducing carbon emissions by so much that we almost wouldn't need to force people to switch to electric cars. Which do not have as much range as gasoline cars for the same price. And a *battery* doesn't have the same life span as a gas tank, because it has to do much more work. Those aren't the fatal flaw, either. (And both are well on their way to not being true any more. Range will double in the next couple of years, as the ltihium metal batteries go into production. Life span will increase greatly, too, though battery packs will still likely cost more than a new engine for a while.) Still, it is indeed to be expected that if we get governments that take global warming seriously, gasoline cars will indeed be phased out. Not until there are electric cars that can actually do everything gasoline cars can do. Which there aren't, and won't be within our lifetimes. Myself, I'd prefer a different course: 1) Switch all electrical power generation to hydro, nuclear, and, where possible, renewables; 2) Bring in gas rationing; switch public transit to electric *trolley buses*, and improve public transit. People will be expected to use public transit to commute to work. Yeah, hold your breath on that. California has dealt with government messing with our cars before. And not kindly. The new gas tax will be removed come November, in a way that prohibits the legislature from ever trying again. What you propose isn't possible in a democracy when the technology to replace gasoline cars simply doesn't exist. And it doesn't. Then for people to use gasoline-powered cars to go shopping and go to the cottage for the weekend won't produce so much carbon as to be a problem. And it's all possible with *proven technology*, without hoping for better electric cars than we have at present. You're smoking the same Kool-Aid as Chrissie is. As a bonus, it will improve employment opportunities for people who can't afford a car. And it will save the environmental impact of manufacturing all those new cars for people - and wear and tear on the existing gasoline-fuelled cars, which now won't have to be junked! I mean, really, if you want to be environmental... I'd rather have a job, and food to eat. And so would everyone else, except delusional losers who can't manager either on their own anyway. -- 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. |

Never? I always thought that of 100 new technologies, 99 of them never catch on, and thus don't get what they need for support. Sure. I was referring to the technologies that _do_ catch on, and electric cars are certainly going to be in that category. They're cheaper to produce, more reliable, much more energy efficient to operate, don't pollute, have better performance. They represent an unstoppable trend on many fronts. And that, of course, will drive the development of all manner of associated and supportive technology and infrastructure development. The first thing electric cars need is electricity that isn't made from fossil fuels. If the electricity they use comes from a coal-fired generating plant, there is no benefit from a carbon point of view. There could still be a local environmental benefit for things like photochemical smog. That's not entirely true. Even from a pure carbon standpoint, electricity produced by natural gas at a modern large power plant results in much less carbon released than the equivalent energy produced by an internal combustion engine. If *that* were to happen, then we would be reducing carbon emissions by so much that we almost wouldn't need to force people to switch to electric cars. If you think people are going to have to be forced, you're not understanding the technology. These cars are so superior in so many ways, that's all that most people will want. Demand will drive that market. Not until they can do everything that people use gasoline cars for. Which they don't, and won't, for a long, long time, if ever. 1) Switch all electrical power generation to hydro, nuclear, and, where possible, renewables; Nuclear is dead. It has no future. Most countries don't want to take the risk, both real and political, and it's simply too expensive and introduces too many problems. There are technological fixes to much of that, but the time and cost of developing them is much greater than what's involved converting to wind, solar, and fully carbon sequestered natural gas. 2) Bring in gas rationing; switch public transit to electric *trolley buses*, and improve public transit. People will be expected to use public transit to commute to work. An excellent idea in principle, although one that I doubt will serve most people in the U.S. I do think that automated cars and car sharing will provide some of these benefits, though. And it's all possible with *proven technology*, without hoping for better electric cars than we have at present. We don't have to hope. Electric cars are already cheaper No, they're not. The same model is more expensive, even *with* the subsidies. Retard. and better for everything except range. And refueling time. Especially on long trips. And the development pace is rapid. The technological risks here are very small. But the laws of physics are immutable. Three megawatt charger to add enoguh miles of drivign to match gasoline. Per charger. Deal with it. Or hallucinate a better world, as you are now. As a bonus, it will improve employment opportunities for people who can't afford a car. And it will save the environmental impact of manufacturing all those new cars for people - and wear and tear on the existing gasoline-fuelled cars, which now won't have to be junked! Shared ownership achieves similar goals. If ridesharing were going to catch on, it would have in the 70s. -- 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. |

Nuclear has no future for widespread energy generation. It would require radical new technology for that to change, and I don't see any real investment in developing such technology.

Too expensive, too politically dangerous, too environmentally and economically risky. And increasingly unnecessary. It may already be too late, no matter what we do. All around the arctic there are vast stores of permafrost which are now melting. That melting is releasing vast amounts of carbon and methane which have been stored away for millennia. All this will be dumped into the atmosphere at rates that dwarf human pollution. This stored carbon exceeds present atmospheric carbon by a factor of 3. All this, of course, has been set in motion by humans digging up and burning fossil fuels. That is akin to setting a torch on fire which is then thrown into a huge pile of wood. The resultant bonfire will be impossible to stop. And besides the carbon and methane, the permafrost also stores large amounts of bacteria which have been shown to re-activate when thawed out. The bacteria will happily munch on the biomass trapped in the permafrost, releasing more methane and CO2. Some scientists now worry that they will also cause health problems that are totally unknown, and for which we have no immunity. Happy hunting, future descendants. Razzy |

Wooden objects usually have to be shaped by *human hands*. Whereas metal objects can be cast or stamped. So that makes them much more expensive, unless they're imported from a low-wage country, and _then_ they cost foreign exchange.

I do think it is very likely that we will continue to see temperatures rise for long enough that major economic and social upheavals will result. Stopping it at this point would probably require expensive, risky, and poorly developed sequestration and geoengineering solutions. |
