Today I'm going to show you an electric vehicle
1
13058
3578
今天我给大家看一个电动交通工具
00:16
that weighs less than a bicycle,
2
16636
3906
它比自行车还轻,
00:20
that you can carry with you anywhere,
3
20542
3346
你可以随身带到任何地方
00:23
that you can charge off a normal wall outlet in 15 minutes,
4
23888
4492
在墙上插座充电15分钟,
00:28
and you can run it for 1,000 kilometers
5
28380
2248
你就能够跑1000公里远
00:30
on about a dollar of electricity.
6
30628
2352
电费大约就1块钱。
00:32
But when I say the word electric vehicle,
7
32980
2288
但是我说电动交通工具时,
00:35
people think about vehicles. They think about cars
8
35268
2888
人们一想到交通工具,他们会想到汽车
00:38
and motorcycles and bicycles, and the vehicles that you use every day.
9
38156
3718
摩托车和自行车,那些我们日常用的交通工具。
00:41
But if you come about it from a different perspective,
10
41874
2296
但是你如果从不同的角度来看,
00:44
you can create some more interesting,
11
44170
2302
你会创造更多有趣的,
00:46
more novel concepts.
12
46472
2680
更新奇的概念。
00:49
So we built something.
13
49152
2256
所以我们做了个东西。
00:51
I've got some of the pieces in my pocket here.
14
51408
2694
我这儿有几个零件在口袋里。
00:54
So this is the motor.
15
54102
2090
这是马达。
00:56
This motor has enough power to take you
16
56192
1609
这个马达有足够的能量带你
00:57
up the hills of San Francisco at about 20 miles per hour,
17
57801
3807
在旧金山以每小时20英里的速度爬坡,
01:01
about 30 kilometers an hour,
18
61608
1826
大约每小时30公里,
01:03
and this battery, this battery right here
19
63434
4090
这个电池
01:07
has about six miles of range, or 10 kilometers,
20
67524
3948
能支持大约六英里,或10公里的范围
01:11
which is enough to cover about half of the car trips
21
71472
2803
足够走大约一半的
01:14
in the U.S. alone.
22
74275
2397
美国境内的汽车旅程。
01:16
But the best part about these components
23
76672
1779
最妙之处是这些零件是
01:18
is that we bought them at a toy store.
24
78451
2197
我们在一家玩具店买来的。
01:20
These are from remote control airplanes.
25
80648
2424
这些是遥控飞机上的。
01:23
And the performance of these things has gotten so good
26
83072
2144
这些零件的性能太好了
01:25
that if you think about vehicles a little bit differently,
27
85216
2296
你要是从不同的角度来考虑交通工具,
01:27
you can really change things.
28
87512
1503
你真能改变事情。
01:29
So today we're going to show you one example
29
89015
1997
今天我们给你们示范一下
01:31
of how you can use this.
30
91012
2077
如何使用这个工具。
01:33
Pay attention to not only how fun this thing is,
31
93089
2799
别光看它多有趣,
01:35
but also how the portability that comes with this
32
95888
3078
也看看它的轻便是如何
01:38
can totally change the way you interact with a city like San Francisco.
33
98966
4347
能够完全改变你与像旧金山这样的城市的互动的。
01:43
(Music)

(音乐)
02:02
[6 Mile Range] [Top Speed Near 20mph]
35
122765
3021
(6 英里的范围,最高速度接近20英里/小时)
02:05
[Uphill Climbing]
36
125786
3500
(爬坡)
02:24
[Regenerative Braking]
37
144094
4034
(再生制动)
02:50
(Applause)
38
170458
6059
(掌声)
02:56
(Cheers)
39
176517
4312
(欢呼)
03:00
So we're going to show you what this thing can do.
40
180829
3293
我们将展示它能做什么。
03:04
It's really maneuverable. You have a hand-held remote,
41
184122
2693
很容易操作的。它有一个手动遥控器,
03:06
so you can pretty easily control acceleration, braking,
42
186815
3579
很容易控制加速,刹车,
03:10
go in reverse if you like, also have braking.
43
190394
4329
倒着走也可以,同样可以刹车。
03:21
It's incredible just how light this thing is.
44
201431
2057
它轻得令人难以置信。
03:23
I mean, this is something you can pick up and carry with you
45
203488
2129
我是说,你可以拿起来,随身携带
03:25
anywhere you go.
46
205617
2936
不论去哪。
03:28
So I'll leave you with one of the most compelling facts
47
208553
3176
我要告诉你们这个技术和这种的交通工具的
03:31
about this technology and these kinds of vehicles.
48
211729
2856
最引人注目的事实之一。
03:34
This uses 20 times less energy
49
214585
3392
比起汽车来,
03:37
for every mile or kilometer that you travel than a car,
50
217977
3367
它每英里或公里能节约20倍的能量,
03:41
which means not only is this thing fast to charge
51
221344
3633
也就是说这个不仅充电快
03:44
and really cheap to build,
52
224977
1689
做起来也很便宜,
03:46
but it also reduces the footprint of your energy use
53
226666
3351
就运输而言也减少了
03:50
in terms of your transportation.
54
230017
1635
能量的消耗。
03:51
So instead of looking at large amounts of energy needed
55
231652
2759
所以不用找大量的能源
03:54
for each person in this room to get around in a city,
56
234411
2934
来让每个人都有空间在市内活动,
03:57
now you can look at much smaller amounts
57
237345
2120
你可以关注耗能量更小
03:59
and more sustainable transportation.
58
239465
2440
和更持久的交通工具。
04:01
So next time you think about a vehicle,
59
241905
1362
所以,下次你要是考虑一种交通工具,
04:03
I hope, like us, you're thinking about something new.
60
243267
3306
希望,像我们这样,想点新奇的东西。
04:06
Thank you.
61
246573
1138
谢谢大家!
04:07
(Applause)
