This is a world-changing invention.

The smoke alarm has saved perhaps hundreds of thousands
1
21330
3000
00:24
of lives, worldwide.
2
24330
2000
00:26
But smoke alarms don't prevent fires.
3
26330
4000
00:30
Every year in the USA, over 20,000 are killed or injured
4
30330
3000
00:33
with 350,000 home fires.
5
33330
2000
00:35
And one of the main causes of all these fires is electricity.
6
35330
4000
00:39
What if we could prevent electrical fires
7
39330
3000
00:42
before they start?
8
42330
2000
00:44
Well, a couple of friends and I figured out how to do this.
9
44330
3000
00:47
So how does electricity ignite residential fires?
10
47330
4000
00:51
Well it turns out that the main causes
11
51330
2000
00:53
are faulty and misused appliances and electrical wiring.
12
53330
3000
00:56
Our invention had to address all of these issues.
13
56330
4000
01:00
So what about circuit breakers?
14
60330
2000
01:02
Well, Thomas Edison invented the circuit breaker in 1879.
15
62330
4000
01:06
This is 130-year-old technology,
16
66330
3000
01:09
and this is a problem, because over 80 percent
17
69330
3000
01:12
of all home electrical fires
18
72330
2000
01:14
start below the safety threshold of circuit breakers.
19
74330
3000
01:17
Hmmm ...
20
77330
2000
01:19
So we considered all of this. And we realized
21
79330
2000
01:21
that electrical appliances
22
81330
2000
01:23
must be able to communicate directly
23
83330
2000
01:25
with the power receptacle itself.
24
85330
2000
01:27
Any electrical device -- an appliance, an extension cord, whatever --
25
87330
4000
01:31
must be able to tell the power outlet,
26
91330
2000
01:33
"Hey, power outlet,
27
93330
2000
01:35
I'm drawing too much current. Shut me off now, before I start a fire."
28
95330
4000
01:39
And the power outlet needs to be smart enough to do it.
29
99330
4000
01:43
So here is what we did. We put a 10-cent digital transponder,
30
103330
5000
01:48
a data tag, in the appliance plug.
31
108330
3000
01:51
And we put an inexpensive, wireless data reader inside the receptacle
32
111330
4000
01:55
so they could communicate.
33
115330
2000
01:57
Now, every home electrical system
34
117330
2000
01:59
becomes an intelligent network.
35
119330
3000
02:02
The appliance's safe operating parameters
36
122330
2000
02:04
are embedded into its plug.
37
124330
3000
02:07
If too much current is flowing,
38
127330
2000
02:09
the intelligent receptacle turns itself off,
39
129330
2000
02:11
and prevents another fire from starting.
40
131330
3000
02:14
We call this technology EFCI,
41
134330
2000
02:16
Electrical Fault Circuit Interrupter.
42
136330
3000
02:19
Okay, two more points. Every year in the USA,
43
139330
2000
02:21
roughly 2,500 children
44
141330
3000
02:24
are admitted to emergency rooms for shock and burn injuries
45
144330
3000
02:27
related to electrical receptacles. And this is crazy.
46
147330
4000
02:31
An intelligent receptacle prevents injuries
47
151330
3000
02:34
because the power is always off,
48
154330
2000
02:36
until an intelligent plug is detected. Simple.
49
156330
4000
02:40
Now, besides saving lives,
50
160330
2000
02:42
perhaps the greatest benefit of intelligent power
51
162330
2000
02:44
is in its energy savings.
52
164330
2000
02:46
This invention will reduce global energy consumption
53
166330
3000
02:49
by allowing remote control and automation
54
169330
3000
02:52
of every outlet in every home and business.
55
172330
3000
02:55
Now you can choose to reduce your home energy bill
56
175330
3000
02:58
by automatically cycling heavy loads
57
178330
2000
03:00
like air conditioners and heaters.
58
180330
3000
03:03
Hotels and businesses can shut down unused rooms
59
183330
3000
03:06
from a central location, or even a cell phone.
60
186330
3000
03:09
There are 10 billion electrical outlets
61
189330
3000
03:12
in North America alone.
62
192330
2000
03:14
The potential energy savings is very, very significant.
63
194330
4000
03:18
So far we've applied for 414 patent claims.
64
198330
4000
03:22
Of those, 186 have been granted:
65
202330
3000
03:25
228 are in process.
66
205330
2000
03:27
And I'm pleased to announce that just three weeks ago
67
207330
3000
03:30
we received our first international recognition,
68
210330
3000
03:33
the 2009 CES Innovation Award.
69
213330
4000
03:37
So, to conclude,
70
217330
2000
03:39
intelligent power can, globally, save thousands of lives,
71
219330
4000
03:43
prevent tens of thousands of injuries,
72
223330
2000
03:45
and eliminate tens of billions of dollars in property damage
73
225330
4000
03:49
every single year,
74
229330
2000
03:51
while significantly reducing global energy consumption.
75
231330
3000
03:54
In the spirit of this year's TED Conference,
76
234330
2000
03:56
we think this is a powerful, world-changing invention.
77
236330
3000
03:59
And I'd like to thank Chris for this opportunity
78
239330
3000
04:02
to unveil our technology with you, and soon the world.
79
242330
3000
04:05
Thank you.
80
245330
