Today I'm going to show you an electric vehicle
1
13058
3578
00:16
that weighs less than a bicycle,
2
16636
3906
00:20
that you can carry with you anywhere,
3
20542
3346
00:23
that you can charge off a normal wall outlet in 15 minutes,
4
23888
4492
00:28
and you can run it for 1,000 kilometers
5
28380
2248
00:30
on about a dollar of electricity.
6
30628
2352
00:32
But when I say the word electric vehicle,
7
32980
2288
00:35
people think about vehicles. They think about cars
8
35268
2888
00:38
and motorcycles and bicycles, and the vehicles that you use every day.
9
38156
3718
00:41
But if you come about it from a different perspective,
10
41874
2296
00:44
you can create some more interesting,
11
44170
2302
00:46
more novel concepts.
12
46472
2680
00:49
So we built something.
13
49152
2256
00:51
I've got some of the pieces in my pocket here.
14
51408
2694
00:54
So this is the motor.
15
54102
2090
00:56
This motor has enough power to take you
16
56192
1609
00:57
up the hills of San Francisco at about 20 miles per hour,
17
57801
3807
01:01
about 30 kilometers an hour,
18
61608
1826
01:03
and this battery, this battery right here
19
63434
4090
01:07
has about six miles of range, or 10 kilometers,
20
67524
3948
01:11
which is enough to cover about half of the car trips
21
71472
2803
01:14
in the U.S. alone.
22
74275
2397
01:16
But the best part about these components
23
76672
1779
01:18
is that we bought them at a toy store.
24
78451
2197
01:20
These are from remote control airplanes.
25
80648
2424
01:23
And the performance of these things has gotten so good
26
83072
2144
01:25
that if you think about vehicles a little bit differently,
27
85216
2296
01:27
you can really change things.
28
87512
1503
01:29
So today we're going to show you one example
29
89015
1997
01:31
of how you can use this.
30
91012
2077
01:33
Pay attention to not only how fun this thing is,
31
93089
2799
01:35
but also how the portability that comes with this
32
95888
3078
01:38
can totally change the way you interact with a city like San Francisco.

6059
02:56
(Cheers)
39
176517
4312
03:00
So we're going to show you what this thing can do.
40
180829
3293
03:04
It's really maneuverable. You have a hand-held remote,
41
184122
2693
03:06
so you can pretty easily control acceleration, braking,
42
186815
3579
03:10
go in reverse if you like, also have braking.
43
190394
4329
03:21
It's incredible just how light this thing is.
44
201431
2057
03:23
I mean, this is something you can pick up and carry with you
45
203488
2129
03:25
anywhere you go.
46
205617
2936
03:28
So I'll leave you with one of the most compelling facts
47
208553
3176
03:31
about this technology and these kinds of vehicles.
48
211729
2856
03:34
This uses 20 times less energy
49
214585
3392
03:37
for every mile or kilometer that you travel than a car,
50
217977
3367
03:41
which means not only is this thing fast to charge
51
221344
3633
03:44
and really cheap to build,
52
224977
1689
03:46
but it also reduces the footprint of your energy use
53
226666
3351
03:50
in terms of your transportation.
54
230017
1635
03:51
So instead of looking at large amounts of energy needed
55
231652
2759
03:54
for each person in this room to get around in a city,
56
234411
2934
03:57
now you can look at much smaller amounts
57
237345
2120
03:59
and more sustainable transportation.
58
239465
2440
04:01
So next time you think about a vehicle,
59
241905
1362
04:03
I hope, like us, you're thinking about something new.
60
243267
3306
04:06
Thank you.
