@Carl, wow, that is some report. I had no idea we were so good; however, it smells very "diesely" in the city of Dublin outside my door at 8.30 in the mornings. > Air quality in Europe — 2016 report, EEA Report No 28/2016 > I would doubt it, why would they, they are trying to get a picture of the EU. However, my hybridisation wish still stands, except it would be more urgent in cities other than Dublin.
Interesting, so you could generate electricity needed on planes from Al+H20, rather than bleed power from the turbofans. I wonder how much it costs to fuel these planes (with Al). Maybe you could make Al fuel from waste electricity when there was no demand on the grid. What do you do with the Al(OH)3 afterwards, can you regenerate it to Al?
I think this is cool, and develops skills and experience in VW towards a full hybrid. What you need now is the ability to drive at say 100 kph on electric - I am guessing 15-20 Kw, so that rather than coasting, you can go on electric, like a hybrid or a PHEV. Even if you had a car that could crawl through city traffic on electric, you would have something. In my view, the key thing is to reduce the use of fossil fuels, you do not need to eliminate it in one fell swoop. If you could sell 4 hybrids rather than 1 EV, you would save a lot more fuel.
It would be nice to get all the diesel cars and trucks out of cities, due to the local pollution (NOx, particualtes and soot). However, this is unlikely to happen any time soon, as EVs are so expensive to buy and range limited. IMO, hybrids, such as this, which could be petrol (or Hydraulic) hybrids are a good idea. Ideally, all stop-start deliveries could be electric or hybrid. Where I live (Dublin) you can see row after row of (70% diesel) cars sitting in traffic, their engines running. If they even had mild hybridisation, their engines could be off for all the stationary (and maybe low speed) times, which would greatly improve air quality.
I wonder how many lines of code it took to do that ... The "coasting on approach to red lights" function is a good idea and could be used for all engine types. All cars could switch the engine off, and electrics could use regenerative braking to recycle the energy. However, it would want to work well or it would be very annoying. + it wouldn't work well for people who see red lights as "guidelines"* rather than actual rules. *in the words of Captain Barbossa from "Pirates of the Caribbean".
I can see it working for very wealthy people, but not "millions" of people. The great unwashed will still be sweating in their cars, buses and subways while the elite whizz around above them in some kind of drone or helicopter. The problem with flying vehicles is that they are huge compared to a person. It is one thing putting 200 people in an A321, but a helicopter with 1 or 2 people is huge waste of space and resources (and noise). [ The money might be better spent on subways or rail. ]
A fair point: the battery charged OK, but the natives terrified and worshiping it.
@EP, sure: you have to get the battery charged, that is the prime directive. IF there is excess wind or solar, you use that, else you just charge. The system would have access to predicted wind (or solar) availability over the next 8 (or whatever) hours to plan the charge. Here is an example of predicted wind availability (in Ireland). http://www.eirgridgroup.com/how-the-grid-works/system-information/ (Not much wind today).
I would go with battery electric + fast charge + perhaps an ICE range extender for "get you home" flexibility. This would make it simpler to move the bus from one place to another and other unusual "range events".
@EP, I don't see why "smart charging" wouldn't work for PHEVs. Lets say you park at 9am and need the car back by 5pm, and have 7 KwH capacity that needs to be replenished. All you need to do is to get it in by 5pm at the lowest cost or lowest CO2 times. You have less time than an overnight smart charge, but the same principles apply, and you are taking up less power at each charge. Here's a question: where should the smart charge intelligence be - in the car, or in the charger ?
@EP, I tried and failed to find EU wide figures. As you say, the US publishes them, but the EU ones are harder to find. If you find some, I would be pleased to see them. I agree on the PHEV angle, it seems like the best solution to the range / battery size problem (if a little expensive). IMO, what you need is a simple way to recharge where you park at work. Better still, a smart charger that charges when demand is low(est), or there is a lot of wind or solar on the grid. If your commute is short, you could just charge at night. BTW, what do you drive ?
It is a total cod. The real CO2 figures are probably 30% higher than that, due to the use of the NEDC testing approach which was not designed for CO2 measurement in the first place and has more holes than a Swiss cheese. The sooner they get a proper "real world" CO2 (and NOx) test, the better. It will cause a few red faces when the Eu Co2/Km level jumps 30%, but better to know the truth than kid yourself. Also, the test regime needs to include some mix of pollutants, not just CO2. AT the very least, it should include NOx and CO2 (in some proportion) to discourage the use of diesels in cities.
Cost maybe ? You can fully charge in 40 minutes, anyhow, which is enough time to eat a meal. Note that at 150Kw, it has a 10:1 drive - charge ratio for moderate driving (assuming moderate driving at 15 Kw).
Adult scooters are very cool, as long as the pavement surfaces are well maintained and smooth. Otherwise you need large wheeled scooters which are hard to fold up small. Also, you need to be a thick skinned individual to absorb any slagging you may get from youths. I saw them (mid size wheeled adult scooters) in use in Copenhagen airport (indoors) and they looked like a lot of fun and very practical - the opposite of a Segway (low tech, narrow, unaggressive).
What is MSP in this context ? Other than that, it sounds good to me if they can scale it.
Sounds good to me. The more hybridisation, the better, especially if it is cheap and can be rolled out quickly and cheaply. We might be able to move people from diesel to MHEVs on gasoline, with improvements in urban air quality.
@roger All fine except the tanks to store it in - and building out a LH2 network to get it to the airdromes. Meanwhile, I'll wait to see it.
Note that ICE driven aeroplanes had hit this speed by 1922. The problem with electric aircraft is the energy density of batteries, which is hopeless compared to chemical fuels. Hybrid aircraft may have a bright future, where batteries are used near the ground (for noise reasons) and a turbine generator is used for climbing and cruising flight. Airbus are abandoning the e-fan in favour of the e-fan-x which is a much larger hybrid: http://aviationweek.com/commercial-aviation/airbus-drops-electric-light-aircraft-larger-e-fan-x
He quotes "All WTW GHG figures from fueleconomy.gov.)" but I couldn't find them. (can anyone ?) They have tailpipe co2 figures, but these make electrics look better than they are, as most are charged from whatever the grid is doing at the moment of charging.
@Dave: "There is no point in oversizing the battery beyond average daily use" - absolutely, I'll accept that, size it to average daily use (+10% ?) and let the range extender do the rest. That is it! - if we can find a decent range extender of any kind, we are more or less done. Better still, get "smart" 3kw chargers at people's places of work (just to keep it topped up). A "smart" charger is one which only charges when the grid is not stressed. You could order (say) 3 kwH power by 5.30 pm with optionally up to 10 KwH if the grid was not stressed (i.e. if there was a lot of wind or solar on the grid). I am glad that is sorted, we can go to the pub now and see how the implementers are getting on later!
@Dave, I am very much in favour of the 30Kw range extender idea and IMO, it doesn't much matter what the power source is. It could be petrol, diesel, ICE Methanol or a fuel cell, maybe powered by methanol. This is because it won't be used all that much - suppose you have a 25 KwH main battery, and a 30 Kw range extender, you are done. The thing is to minimise the cost of this, and that includes fuel storage and emissions control as well as power generation. It won't be used very much, so the per mile efficiency is not that important. Also, all it has to do is generate electricity, mostly at a steady rate, so it can be simpler than an ICE which must run at a variety of speeds and torques. A methanol reformer / fuel cell might be perfect for this, IF you had a methanol dispensing network.
a: With Trump in the white house, there will be less pressure to conserve in the US (although Europe and Japan will keep up the pressure). b: The extra demand will from countries outside the OECD See the following list of countries by population size: 1 China 1,382M 2 India 1,326M 3 United States 324M 4 Indonesia 260 5 Brazil 209 6 Pakistan 192 7 Nigeria 186 8 Bangladesh 162 9 Russia 143 10 Mexico 128 11 Japan 126 12 Philippines 102 13 Ethiopia 101 14 Vietnam 94 15 Egypt 93 16 Germany 80 17 Iran 80 As these countries get rich, they will want cars, but won't be able to afford (or charge) EVs, so, IMO, demand for gasoline will continue once these guys get going. China might have the political will to force people into efficient cars, but many of the rest won't. The oil that the rich countries conserve will be consumed, at lower prices, by the developing world. (So avoid low lying property !)
I would have thought that it would e better to leave methanol as methanol and burn it directly in a generator or engine. At least methanol is a liquid and easy to store / transport, not like H2.
Good for them, but it sounds expensive (for a golf sized car). The 96kw Bluemotion version sounds interesting - hope it is cheaper. Interesting to see a gasoline powered car that powerful with such low CO2 and mpg figures (even in NEDC). It is a very good thing, because I can see diesel cars being banned from many city centres sooner rather than later.
Interesting how diesel got worse from 1990 to 2000 before getting marginally better to 2005. If this is taken seriously, "they" will have to give up diesel in cities, and probably switch to gasoline hybrids or diesel PHEVs (or full EVs). I suppose the question is how to get the most polluting vehicles out without bankrupting loads of small businesses and individuals. One approach would be to look at the emissions / mile and the number of miles, rather than just the per mile rate. Some old guy who does 3000 miles / year is not as big a problem as a delivery van doing 20K / year.
