Batteries have been around for 210 years and there is nothing on horizon that will provide anywhere near the energy density required to power something like a big rig truck, a farm tractor, construction machinery, airplanes, a train, or a boat of any size. Even pure electric cars are not practical as a replacement for an ICE car in other than very limited conditions. -- Jim Pennino Remove .spam.sux to reply.- Hide quoted text - - Show quoted text - Wrong. Yes, you usually are. http://en.wikipedia.org/wiki/File:Energy_density.svg Conventional gasoline: 34.8 MJ/L 43 MJ/kg 100LL: 44 MJ/kg 32 MJ/L Jet A 43 MJ/kg 33 MJ/L Lithium ion nanowire battery: 2.54 MJ/kg (experimental, bleeding edge) Supercapacitor: .01 MJ/kg Â*(experimental, bleeding edge) -- Jim Pennino Ok, and let's examine the source of this data. LOL! Some kid named Scott on Wikipedia. Ya gotta stop believing everything you read on Wikipedia. On top of that, this is outdated technology. Pick any site you want and you will find the numbers are essentially the same. The energy density numbers will vary around a couple of percent depending on the method used to get them, but they will not change by an order of magnitude, which is what is needed for batteries, or three orders of magnitude which you would need for supercapacitors. And no, lithium ion nanowire batteries are bleeding edge technology and don't exist outside of a lab. Supercapacitors powering automobiles is a joke. If you have some real source, i.e. a real company or university, of better battery technology, let's see it. Pie in the sky press releases don't count, only lab results. -- Jim Pennino Remove .spam.sux to reply. |

If you're interested in reading more in depth about Graphene, the one molecule thick wafer of honey-combed carbon, somewhere there's an explanation of it's ultracapacitor applications that would antiquate anything we've see thus far. --- Mark |

One of those 'unfortunate facts' that the dreamers cannot get their heads around Precluding the law of diminishing returns, just off-hand I'd think a truck-sized electric motor would fix that. (along with a commensurate power source) *Ever seen electric drag-strip cars? *The IC powered cars cannot even come close. The tork is just too great. What do truckers rely on? *Tork. The word is torque and a 40 ton load that has to be delivered a thousand mile away is going to require the internal combustion engine |

Presumably, those people are smoking something other than tobacco! Within 24 months, you're going to see more electric cars come out of the woodwork than you can shake a stick at. There are many, many aviators excited and working on this too. Grants are being handed out. Endowments are being granted. 2.4 Billion dollars, that's with a B...last year alone! And a good point it is -- if we achieve a) cheap, clean electricity (e.g. fusion, solar) and b) practical batteries, then we'll see incredible changes in air quality, the economy, and even world politics. I would guess that the use of internal combusion engines will not actually be outlawed. *More likely, people who want to operate them (e.g. antiques collectors) will simply pay a pollution tax when they buy the fuel. Electric vehicles are simply not practical, except for specialized uses, where short range and duration are not problems. We're already up to 150miles on a charge, and this whole thing is just getting ramped up. Give it 2 years and you'll change your mind. This excludes aircraft, meaningful automobile use, for starters. Electric planes are flying and we've just scratched the surface of this new technology. Cars are coming on the market this year. Next year in quantity, and are being mass produced right now in the United States by Korean parent companies. Bear in mind that if 99% of the vehicles switch to electric, then the few ICEs that remain won't be generating enough pollution to actually worry about. *We might even see a relaxation of pollution laws rather than a tightening of them. 'tain't going to happen! smile I'm not holding my breath though. *Batteries suck and they're not getting much better. *It will be exciting to see what the next 50 years brings. Batteries have to carry both fuel and oxidizer, like a rocket system does. If an ICE vehicle had to carry its own air supply, its propellant weight would expand by 15 times! Apples and oranges. We're talking ion transfer only. I realistically see batteries of the future shrinking down to the size and weight of cigarette packs, with more voltage and storage than what we have now. Just like cell phones and computers did. --- Mark |

(not that there's anything wrong with that) Anyhoo...forget about advocates. They were the first wave. Now it's progressed on to actual manufacturers and distributors. I can see these things man. ( I'm sober) Dateline 2016: "Cessna has announced that after trial tests and FAA final certification, they are proud to announce their new line of electric airplanes. With their elimination of a need for either an intake or exhaust system, the performance numbers are quite impressive, extending the Skyhawk service ceiling to 20 thousand ft." --- Mark |
