How I built a nuclear reactor at the age of 13 | Jamie Edwards | TEDxCERN
-
0:20 - 0:22Nuclear power.
-
0:22 - 0:26I guess this is what most people think of
when it comes to nuclear power. -
0:26 - 0:32Well, for me, this is what I think of;
or more specifically, this. -
0:32 - 0:36But before I tell you about that,
let me tell you how all this started. -
0:37 - 0:40Even as a young kid, I was
always asking questions. -
0:40 - 0:42Questions to my mom, my dad, my teachers,
-
0:42 - 0:45but eventually, they weren't able
to answer my questions anymore. -
0:45 - 0:48So, I turned to the Internet
to find some answers. -
0:48 - 0:50It was on the Internet
that I came across this guy, -
0:50 - 0:54Taylor Wilson, who'd created
nuclear fusion at 14. -
0:54 - 0:58I was like, "Wow! Fusion!
In the back garden!" -
0:58 - 0:59I had to find out more.
-
0:59 - 1:03So, while searching online,
I came across fusor.net, -
1:03 - 1:06a group of amateur scientists
who were building these Farnsworth fusors. -
1:06 - 1:08It was there that I worked out
-
1:08 - 1:11that it was actually possible
for me to build one of these. -
1:11 - 1:14I figured it'd cost around 2,000 pounds.
-
1:14 - 1:16Slight problem,
I didn't have 2,000 pounds. -
1:16 - 1:18I was going to have to raise
the money myself, -
1:18 - 1:21so I started writing
to some local nuclear labs, -
1:21 - 1:23big engineering companies, universities.
-
1:23 - 1:24But you know what?
-
1:24 - 1:27For some reason, they didn't want
to give 2,000 pounds -
1:27 - 1:29to a 13-year-old trying to build
a nuclear reactor. -
1:29 - 1:30(Laughter)
-
1:30 - 1:32No idea why.
-
1:32 - 1:34So instead, I asked
my school science teacher -
1:34 - 1:36if she could help with my project.
-
1:36 - 1:38She suggested we tried the head teacher.
-
1:38 - 1:41So after a "Dragons’ Den"
style pitch to Mr. Hourigan, -
1:41 - 1:44I managed to persuade him
to part with 2,000 pounds. -
1:44 - 1:48So, armed with the school
credit card, I turned to eBay. -
1:48 - 1:52I bought parts from all over the world:
power supplies from the USA, -
1:52 - 1:55resistance from Hong Kong
and vacuum pumps from Lithuania. -
1:55 - 1:58I built this. My fusion reactor.
-
2:00 - 2:03However, I couldn't get
everything from eBay. -
2:03 - 2:06Their terms and conditions
were a little restrictive, -
2:06 - 2:09even the specialist gas supply
seemed concerned. -
2:09 - 2:10They wanted to know why exactly
-
2:10 - 2:15a 13-year-old schoolboy from Lancashire
wanted ten liters of deuterium gas. -
2:16 - 2:17- Anyway...
- (Laughter) -
2:17 - 2:21This is the neutron detector,
it's a key part of the reactor. -
2:21 - 2:24I use it to tell me if the reaction
has actually happened or not. -
2:24 - 2:26However, they are not easy to get hold of.
-
2:26 - 2:29I had to call everyone I knew
to find someone who might know someone -
2:29 - 2:32who might just happen to know someone else
who actually has one of these. -
2:32 - 2:35In the end, a local university
lent me this one. -
2:35 - 2:39The high-voltage power supply
was one of the most expensive parts, -
2:39 - 2:42but when it arrived
from the USA, it didn't work. -
2:42 - 2:45Even to this day,
I haven't figured out why. -
2:45 - 2:47But luckily, a local switchgear company
-
2:47 - 2:51not only lent me the kit to use it,
they also taught me how to use it safely. -
2:51 - 2:53There was so much about safety.
-
2:53 - 2:56Apparently, there was some concern
about letting a 13-year-old loose -
2:56 - 2:58with a nuclear reactor in school.
-
2:58 - 2:59Not sure why.
-
2:59 - 3:01One of the conditions was
-
3:01 - 3:04I had to be over two meters away
from the reactor while in operation. -
3:04 - 3:06Slight problem, you see these arms?
-
3:06 - 3:08There was no way I could reach.
-
3:10 - 3:12But thanks to the school's tech department
-
3:12 - 3:13and some complex engineering,
-
3:13 - 3:15we made these.
-
3:16 - 3:20[They designed] broom handles with bits
of plastic, superglued to the end, -
3:20 - 3:23so I could operate
the controls from a distance. -
3:23 - 3:25(Laughter)
-
3:25 - 3:26There was also the problem
-
3:26 - 3:29that I might touch the reactor
while it was in operation. -
3:29 - 3:31So we made a high-tech chicken wire cage,
-
3:31 - 3:33and put it around the reactor
so I couldn't touch it. -
3:33 - 3:36There was also the problem
of a high-energy neutron radiation -
3:36 - 3:37coming out of the reactor.
-
3:37 - 3:41So this was my solution:
my sister's fish tanks. -
3:41 - 3:43Minus the fish, of course.
-
3:43 - 3:44We filled them with a boron solution
-
3:44 - 3:48to act as moderator
and absorber of the neutrons. -
3:49 - 3:52And finally, just in case
I managed to electrocute myself, -
3:52 - 3:54we made this.
-
3:54 - 3:57It is indeed a hook
made of old bike inner tubes -
3:57 - 4:01in case I managed to electrocute myself
and needed rescuing. -
4:02 - 4:05So, the big day had come.
-
4:05 - 4:08I was feeling calm
until the press started turning up. -
4:08 - 4:10I might have mentioned
something to Mr. Hourigan, -
4:10 - 4:13about the possibility
of some PR from the school. -
4:13 - 4:15I was only thinking the local paper.
-
4:15 - 4:18But press from all over
the place turned up. -
4:18 - 4:21So, I had everything set up,
the cameras were ready, -
4:21 - 4:24my hook was at the ready,
and then we switched on the reactor. -
4:24 - 4:26The first thing I did
was pump down the chamber -
4:26 - 4:28and apply the high voltage.
-
4:28 - 4:33That's when I achieved this: plasma,
a key step in producing fusion. -
4:33 - 4:35I played with this for a while,
until I was confident -
4:35 - 4:38I was getting the balance right
between power and vacuum, -
4:38 - 4:41and then all that I had to do
was up the voltage, -
4:41 - 4:43and add in a tiny bit of deuterium gas.
-
4:44 - 4:46I achieved this:
-
4:47 - 4:49a reading on the neutron detector.
-
4:49 - 4:51I'd done it. It was amazing.
-
4:51 - 4:53All my hard work had paid off.
-
4:53 - 4:55But now, as a young scientist,
-
4:55 - 4:57I now need to go back
to the experiment and do it again -
4:57 - 5:00because as you all know, in science,
-
5:00 - 5:03we need to repeat our experiments
and duplicate our results, -
5:03 - 5:04and that's my current focus.
-
5:04 - 5:06But none of this would have happened
-
5:06 - 5:10if it weren't for a science teacher
who believed in the dreams of her pupils, -
5:10 - 5:15and a head teacher who was willing
to take a risk to give me the opportunity. -
5:15 - 5:18So, to any young scientist out there,
no matter how young: -
5:18 - 5:20nothing is ever too big for you to try.
-
5:20 - 5:24All you need is curiosity,
determination, and an open mind. -
5:24 - 5:25Thank you.

5:25 - 5:27(Applause)

- Description:
-
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
What does it take to build a nuclear reactor? Jamie Edwards started out on his journey at age 13 to beat Taylor Wilson's record of being the youngest person to achieve nuclear fusion. He tells of the obstacles he faced as a young schoolboy while trying to achieve his dream, such as trying to convince his headmaster to order deuterium on eBay.
At 13 years old, Jamie Edwards attempted to become the youngest person ever to achieve nuclear fusion by colliding the nuclei of hydrogen atoms via inertial electrostatic confinement in his school lab. When Jamie told his headmaster about his plan to build the nuclear reactor and asked for funding, the reply was "Will it blow up the school?" Jamie got the funding, and rest assured, the school still stands. For his next project, Jamie - who wants to be a nuclear engineer or work in theoretical physics - has his sights on building a miniature Hadron Collider. He's now 14 years old.
