A skateboard, with a boost

  • 0:01 - 0:05
    Today I'm going to show you an electric vehicle
  • 0:05 - 0:09
    that weighs less than a bicycle,
  • 0:09 - 0:12
    that you can carry with you anywhere,
  • 0:12 - 0:16
    that you can charge off a normal wall outlet in 15 minutes,
  • 0:16 - 0:19
    and you can run it for 1,000 kilometers
  • 0:19 - 0:21
    on about a dollar of electricity.
  • 0:21 - 0:23
    But when I say the word electric vehicle,
  • 0:23 - 0:26
    people think about vehicles. They think about cars
  • 0:26 - 0:30
    and motorcycles and bicycles, and the vehicles that you use every day.
  • 0:30 - 0:32
    But if you come about it from a different perspective,
  • 0:32 - 0:34
    you can create some more interesting,
  • 0:34 - 0:37
    more novel concepts.
  • 0:37 - 0:39
    So we built something.
  • 0:39 - 0:42
    I've got some of the pieces in my pocket here.
  • 0:42 - 0:44
    So this is the motor.
  • 0:44 - 0:46
    This motor has enough power to take you
  • 0:46 - 0:50
    up the hills of San Francisco at about 20 miles per hour,
  • 0:50 - 0:51
    about 30 kilometers an hour,
  • 0:51 - 0:56
    and this battery, this battery right here
  • 0:56 - 0:59
    has about six miles of range, or 10 kilometers,
  • 0:59 - 1:02
    which is enough to cover about half of the car trips
  • 1:02 - 1:05
    in the U.S. alone.
  • 1:05 - 1:06
    But the best part about these components
  • 1:06 - 1:09
    is that we bought them at a toy store.
  • 1:09 - 1:11
    These are from remote control airplanes.
  • 1:11 - 1:13
    And the performance of these things has gotten so good
  • 1:13 - 1:16
    that if you think about vehicles a little bit differently,
  • 1:16 - 1:17
    you can really change things.
  • 1:17 - 1:19
    So today we're going to show you one example
  • 1:19 - 1:21
    of how you can use this.
  • 1:21 - 1:24
    Pay attention to not only how fun this thing is,
  • 1:24 - 1:27
    but also how the portability that comes with this
  • 1:27 - 1:31
    can totally change the way you interact with a city like San Francisco.
  • 1:31 - 1:37
    (Music)
  • 1:51 - 1:54
    [6 Mile Range] [Top Speed Near 20mph]
  • 1:54 - 1:57
    [Uphill Climbing]
  • 2:12 - 2:16
    [Regenerative Braking]
  • 2:38 - 2:45
    (Applause)
  • 2:45 - 2:49
    (Cheers)
  • 2:49 - 2:52
    So we're going to show you what this thing can do.
  • 2:52 - 2:55
    It's really maneuverable. You have a hand-held remote,
  • 2:55 - 2:58
    so you can pretty easily control acceleration, braking,
  • 2:58 - 3:03
    go in reverse if you like, also have braking.
  • 3:09 - 3:11
    It's incredible just how light this thing is.
  • 3:11 - 3:14
    I mean, this is something you can pick up and carry with you
  • 3:14 - 3:17
    anywhere you go.
  • 3:17 - 3:20
    So I'll leave you with one of the most compelling facts
  • 3:20 - 3:23
    about this technology and these kinds of vehicles.
  • 3:23 - 3:26
    This uses 20 times less energy
  • 3:26 - 3:29
    for every mile or kilometer that you travel than a car,
  • 3:29 - 3:33
    which means not only is this thing fast to charge
  • 3:33 - 3:35
    and really cheap to build,
  • 3:35 - 3:38
    but it also reduces the footprint of your energy use
  • 3:38 - 3:40
    in terms of your transportation.
  • 3:40 - 3:42
    So instead of looking at large amounts of energy needed
  • 3:42 - 3:45
    for each person in this room to get around in a city,
  • 3:45 - 3:47
    now you can look at much smaller amounts
  • 3:47 - 3:50
    and more sustainable transportation.
  • 3:50 - 3:51
    So next time you think about a vehicle,
  • 3:51 - 3:55
    I hope, like us, you're thinking about something new.
  • 3:55 - 3:56
    Thank you.
  • 3:56 - 4:02
    (Applause)
Title:
A skateboard, with a boost
Speaker:
Sanjay Dastoor
Description:

Imagine an electric vehicle that can get you to work -- or anywhere in a six-mile radius -- quickly, without traffic frustrations or gasoline. Now imagine you can pick it up and carry it with you. Yes, this souped-up skateboard could change the face of morning commutes.
