What use is wireless charging, to a 1000 tonne cargo ship? What use is wireless charging, to an Airbus? What use is wireless charging to a lorry? You promote a fantasy, Baron. Electric vehicles simply are not practical enough for long distance travel, or heavy vehicles. Hydrocarbons are. Biofuels, synthetic fuels, both are better options than your fixation with batteries. They reckon commercial air travel need 1200Wh/kg. Solid state looks like it might achieve it. It's a tough one but then high speed trains are replacing short distance air travel, as per < 500m. I don't think it really matters. What matters is continual improvement on what we have. You can't put down a technology just because it wont solve every damn problem you have. Forget the crap spouted by environmentalists and look a the business cases. If there is money to be made we had better get onto it. You don't need to be jack of all trades, just master of one or two. |

He is only fixated with batteries because China makes most of them - if China led the world in fuel cell technology they would be great and batteries crap. How witty of you. Do you feel better now you have taken the piss? |

An Airbus A320 has a range of 3300 nautical miles.
No way is a battery going to match that.
Next, 1000 ton cargo ships.
No way is a battery going to do the job.
Face it, the future is hydrocarbons.
The interesting question is how we produce them, without environmental damage.

EVs were the tech of the future in 1904. They're a technological dead end. Liquid fuel beats batteries every time. I agree. Battery tech needs to be an order of magnitude more powerful than it is now to make a battery vehicle as useful as an IC..this is a massive demotion. There is no reason to believe that battery tech will progress to this degree, in fact , quite the converse, there are good reasons to believe we are near the practical limit now |

You can do wireless charging now. That might solve the bus in continual use problem. It can charge at the stops. Also never draw conclusions on a technology until you have properly tested it. These things are impossible to predict theoretically or by guesswork. Science always goes on empirical evidence. Preliminary tests look good. That's all i know. There are always bugs and we do not know until we are there. Wireless Charging ... How efficient is that ? To charge a bus, everyone on it will be glowing blue |

Tesla claim they can achieve 97% |

This thread is about useful biofuels which can even power airliners and cargo ships, not useless lithium ion batteries which can incinerate them.

Wireless Charging ... How efficient is that ? To charge a bus, everyone on it will be glowing blue > 90%. Tesla claim they can achieve 97% Well a quick look around websites OFFERING wireless charging uggest 83-92% A look around sites validating the efficiency of such chargers suggest more like 70% But this is a diversion anyway Even if you fitted a wireless charger at every single stop, the time spent stopped is about 5% of the time on the road so it will be a pointless waste of money. But this thread wasn't about battery technology It was about biofuel I know how to make ut. I have made it. But it is a huge drain on food crop land. There was a YouTube vid about making it microbiologically. That would be fun, but it won't be allowed in Wales as it would be an unwarranted incursion of English speaking boffins intomlands Welsh speakers think are theirs. Once they've starved to death my grand daughter's generation will be able to move in and get on with it.... |

Anyway, I definitely heard 97% and some of the new batteries are fast charging. For cars it is possible to charge at 1km per second. That's not wireless, but just to show what batteries can charge at. With wireless the efficiency drops off with distance.

The technology is not that new, Baron, and a 97% efficiency is the sort of figure quoted by the engineering manual for platform controllers buried in the track for signal loss when transmitting RF to trainborne induction devices used to control alignment of coach to platform on the London underground where access doors prevent easy suicide routes for unstable merchant bankers.
Therefore this is the figure I would expect the marketing dept to peddle, and I suspect you picked it up from one of the less scrupulous such sellers.
Alibaba is full of them, it is well named....

This thread is about biofuels, you cannot wirelessly charge an Airbus. You can run it on biofuel.
