  • I Love The Video It Can Increase My Knowledge discusses their recent efforts to establish highly serviceable fleets, including battery-switchable taxis, in tests markets in Japan and Denmark as well as to spur the development

  • Good, I like that you share this video, I wish success always discusses their recent efforts to establish highly serviceable fleets, including battery-switchable taxis

  • Good, I like that you share this video, I wish success always Global Transition to Electric Vehicles

  • I Really Like The Video From Your discusses their recent efforts to establish highly serviceable fleets, including battery-switchable taxis, in tests markets

  • Your Video Is Very Useful Sharing discusses their recent efforts to establish highly serviceable fleets, including battery-switchable taxis

  • good video.

  • For me electric cars are less efficient however it is more earth friendly.

  • If US politicians would agressively pursue alternative energy(wind, solar, etc.) instead of the money from the oil companies, your electric for charging would be clean and cheaper. Why do you think the US lags the world in alternative energy generation? An area of 15 sq.mi. of solar farm in Nevada could supply the whole country. The tech is here; it's all about the Benjamins!

  • @Digidoc316 Renewable energy accounted for 11.14 percent of the domestically produced electricity in the United States in the first six months of 2010. The US had ~18% of world wind power in 2010. As of Feb 2011 US has a 40.2 GW of installed capacity(in wind) with another 5.6GW under construction.(Solar PV)had 435MW in 2009 and 2x+ in 1 year to 878MW. More 65,000 homes and businesses added solar water heating. 1.6GW are under construction. US has 30% of world geo. capacity. I can keep going.

  • Thank you

  • Electricity from coal burning power stations isn't green power. It's worse for the environment than petrol. I'm sticking with petrol to save the environment until a real solution comes along.

  • @stephenspielberger Supremely and utterly incorrect. Simply and proven beyond question to not be true. How else can I put this. You are not correct. Just saying.

  • @bobbyllew, are you saying that burning coal is superior to burning petrol? Perhaps the lack of an exhaust pipe on the car makes it clean... if we disregard the smoke stack bellowing out C02 at the power station.

  • @stephenspielberger I am indeed saying that. This is of course with the proviso that burning coal is idiotic and we should stop as soon as possible. We have to convert our electricity generating capacity to non fossil fuel ASAP. That said, our ability to reduce and capture carbon from one central, highly efficient coal burning power plant is far easier and cheaper than trying to reduce the output of many 100's of millions of steam age tech internal combustion engines

  • @stephenspielberger The 'coal is worse than petrol' argument is utterly flawed. If I charge my electric car from a coal burning power plant alone (60% of power is from coal in UK) it produces 40gm of Co2 per km. Using the same criteria (well to wheel Co2) even the most 'eco' mini 2 seater petrol car is around 300 gms, and average family sedans, between 5 and 600 m of Co2 per km. Where did I get my figures from. Honda and BMW.

  • i think its very interesting that Canada is not taking any steps to implement the use of electric vehicles.. strangely enough it is taking an opposite approach a Texan approach by placing great restrictions through legal jargon and policies that are subject to continual change making it difficult to meet the (most recently) proposed standards..

  • If the batteries are changed out by robots why does the battery station have limited hours, why isn't it entirely robotic? I think this can work in Europe, Asia, and Isreal, but the US market is going to be the most challenging since fuel prices are highly subsidized (directly, through environmental cleanup efforts, and through military influence in oil producing regions/fiefdoms) and distances traveled are typically longer.

  • Very nice talk. I would love to see a map of where you plan to put the charge spots and battery change stations in Denmark. (Google maps would be handy here). If you publish the positions of the spots then we can create iphone apps such as "Find the nearest charging station".

  • @anotherelvis Answer to myself: If you search google maps for the string "earthenergy" then you find a map with a few charging spots. (Not battery exchange stations). But I don't think that this map is complete.

    I suspect that they end up placing most of the battery echange stations near Copenhagen, because a large percentage of Denmark's leftist urban population lives there.

    A quick estimate say that you need 5-10 battery exchanges to drive from one end of the country to the other.

  • @anotherelvis More math: If you drive at 90 kilometers per hour, and the battery lasts for 60 kilometers, then you have to exchange battery once per 40 minutes. If the battery exchange takes 5 minutes, then you spend around 10% of your time exchanging battery. That is not so bad.
