:00:00. > :00:00.In around ten minutes it's time for Newswatch,
:00:00. > :00:37.Energy - as our demand for it grows, the world is faced with a challenge.
:00:38. > :00:45.When we burn coal, the energy that has been stored inside formally
:00:46. > :00:55.-- for millions of years is released, to power
:00:56. > :01:00.But so, of course, is all the bad stuff that is polluting
:01:01. > :01:03.Countries have met and agreed to reduce carbon emissions
:01:04. > :01:05.and invest in clean energy solutions.
:01:06. > :01:08.We are harnessing more solar and wind energy than ever,
:01:09. > :01:11.and last month the UK had its first day of electricity supply
:01:12. > :01:16.But green power is still a long way from taking over from fossil fuels.
:01:17. > :01:20.But what if there was a clean energy source that could release 10 million
:01:21. > :01:23.times more energy than fossil fuels, with an almost limitless supply
:01:24. > :01:32.which could keep the planet running for millions of years?
:01:33. > :01:38.Well, turns out, there is, and the answer lies in the stars.
:01:39. > :01:41.In the heart of the Sun, under intense pressure and heat,
:01:42. > :01:46.hydrogen atoms change from gas into superhot plasma,
:01:47. > :01:49.and, in this burning soup, they fuse together forming helium,
:01:50. > :01:56.and releasing immense amounts of energy.
:01:57. > :02:00.This is nuclear fusion and this is what scientists have been trying
:02:01. > :02:04.for more than 60 years to recreate down here on Earth.
:02:05. > :02:11.We have to do something similar to a star, which has gravity,
:02:12. > :02:14.and to do that we use magnetic fields.
:02:15. > :02:16.And we're talking about magnetic fields that create
:02:17. > :02:18.more pressure than the water pressure at the bottom
:02:19. > :02:22.So you've got this huge pressure trying to compress the plasma,
:02:23. > :02:27.and you've got to hold it in place for a very long time as well, to get
:02:28. > :02:39.If you can keep the superhot plasma in place for long enough,
:02:40. > :02:42.the energy released can keep everything hot, without the need
:02:43. > :02:46.The fusion then becomes self-sustaining, that's
:02:47. > :02:58.We are making progress, though, we have already achieved fusion,
:02:59. > :03:01.and some of the best fusion happens inside machines called tokamaks.
:03:02. > :03:10.Now this one is just outside Oxford, which turns out to be
:03:11. > :03:16.a bit of an epicentre for fusion technology.
:03:17. > :03:19.The world's largest tokamak is just 15 minutes up that way.
:03:20. > :03:23.There is a problem with these machines, and that is that you end
:03:24. > :03:26.up having to put much more energy into these things than you ever
:03:27. > :03:34.But the company here is taking a different route.
:03:35. > :03:39.This is the lab of Tokamak Energy, which is developing relatively small
:03:40. > :03:43.Smaller prototypes can be tested and improved much
:03:44. > :03:48.quicker and more cheaply, as the science is understood
:03:49. > :03:55.This approach means the team may be the first to work out how to produce
:03:56. > :04:04.Oh! My word!
:04:05. > :04:12.Inside here, we are generating plasma, which is gas
:04:13. > :04:16.with electricity flowing through it and we're going to fuse atoms
:04:17. > :04:20.together, join them together, to generate fusion energy.
:04:21. > :04:30.And this light show isn't even fusion.
:04:31. > :04:33.This is just a warm up which is hoped will happen
:04:34. > :04:37.And then what we're going to do is heated up to over
:04:38. > :04:39.10 million degrees, up towards 100 million degrees...
:04:40. > :04:44.We won't be able to keep our face this close
:04:45. > :04:48.We will have to be further away outside some sort
:04:49. > :04:51.But it will actually start to go transparent,
:04:52. > :04:53.as the plasma gets really hot, ten times the temperature
:04:54. > :04:56.of the Sun, 100 times the temperature of the sun.
:04:57. > :04:59.Once they have achieved the temperatures, they need to keep
:05:00. > :05:02.the plasma in place long enough for it to become self-sustaining
:05:03. > :05:05.and this is what the team hopes will create magnetic fields
:05:06. > :05:14.Instead of thick copper cables, a strip of super-thin superconductor
:05:15. > :05:20.All this sounds hopeful, but the joke is that nuclear fusion
:05:21. > :05:29.If successful, it will mean the end of our reliance on fossil fuels,
:05:30. > :05:32.but there's still a lot of science to do between now and then.
:05:33. > :05:36.It could be a fantastic source of energy, likely to be the most
:05:37. > :05:38.important source of energy in the 22nd century.
:05:39. > :05:43.The point is, we need it now, and so we want to make faster
:05:44. > :06:06.It is one of the biggest fund-raising events of the year.
:06:07. > :06:09.Nearly 40,000 people ran this year's London Marathon and wealth funds
:06:10. > :06:11.are still being counted, organisers are hopeful
:06:12. > :06:14.they will smash last year's record of ?59 million raised.
:06:15. > :06:16.Online fundraising platforms now play a big role
:06:17. > :06:18.in attracting more donations, pushing the charities' causes
:06:19. > :06:21.across to users whilst also enabling them to give money
:06:22. > :06:24.JustGiving, one of the biggest players, raised just under
:06:25. > :06:31.This is a figure that charities may not have been able to raise
:06:32. > :06:36.without these sites, but these donations are also big business.
:06:37. > :06:38.JustGiving takes up to 5% commission, whilst others,
:06:39. > :06:44.They say the fees cover operational costs and innovations to ultimately
:06:45. > :06:53.But for charities, this commission is money that's not
:06:54. > :07:00.So the majority of our funding comes from individual fundraisers.
:07:01. > :07:03.For example, one of our runners is currently on ?1500,
:07:04. > :07:06.and the commission on that is going to be about ?100.
:07:07. > :07:10.And on the ground, that translates into care for ten kids that
:07:11. > :07:18.could have received a top to toe checkup,
:07:19. > :07:20.HIV testing and TB testing and be insured their
:07:21. > :07:24.Starfish is a small charity which helps vulnerable
:07:25. > :07:28.children in South Africa, who are affected by HIV and poverty,
:07:29. > :07:32.and a lot of its money goes into running a mobile health clinic.
:07:33. > :07:36.In the UK, the charity Big Kid helps vulnerable young people in south
:07:37. > :07:43.Both organisations have been experimenting with Kind Link,
:07:44. > :07:45.a site which promises to give charities although collected
:07:46. > :07:48.donations and will not make its money from commissions.
:07:49. > :07:53.I went to meet its founder, Iskren Kulev, who traded
:07:54. > :07:56.in corporate life and set up a home office, just
:07:57. > :08:02.KindLink didn't start as a company, KindLink started as an idea to be
:08:03. > :08:09.a social enterprise/charity that helps charities.
:08:10. > :08:11.For him, it's all about transparency.
:08:12. > :08:14.He wanted to create a platform where charities would post updates.
:08:15. > :08:16.The biggest problem with the charities is how
:08:17. > :08:20.they communicate with their donors and
:08:21. > :08:28.do the donors trust were the money is going?
:08:29. > :08:31.About 70% of donors say they would make more if they knew
:08:32. > :08:33.what was happening with their donation.
:08:34. > :08:36.They have also added a feature to show people how much money
:08:37. > :08:39.the charity has received and how much it has spent.
:08:40. > :08:42.How has your background in financial tech helped you to put this together
:08:43. > :08:46.and also maybe to work the system a bit, because it's all about making
:08:47. > :08:50.money, making money now not for businesses but for good causes.
:08:51. > :08:52.It's always a matter of negotiation, I would say.
:08:53. > :08:56.I will go firstly through volume is important, how you present
:08:57. > :09:05.When I know where they can make a compromise, I can try to come up
:09:06. > :09:07.with a deal which would work for both of us.
:09:08. > :09:11.See, this is a guy you want on your side, because he knows how
:09:12. > :09:15.And so far it's s proving successful, with more than 170
:09:16. > :09:19.How would you improve on what you are doing on the pitch?
:09:20. > :09:23.For Big Kid, it's able to spend more money on its programs,
:09:24. > :09:26.like this one, which trains young people to be football coaches.
:09:27. > :09:28.It has helped me, definitely, especially with school
:09:29. > :09:36.In school, I wasn't the good kid, if you understand.
:09:37. > :09:41.Well, instead of taking commission from donors,
:09:42. > :09:43.it plans to take the money from businesses.
:09:44. > :09:46.They have developed this platform for companies to build
:09:47. > :09:49.a profile for themselves showcasing the good causes they support
:09:50. > :09:52.The companies will be charged a monthly fee.
:09:53. > :09:56.I think it is quite fitting that KindLink have set themselves up
:09:57. > :09:58.just across the river from Canary Wharf, where
:09:59. > :10:00.the financial industry makes its billions.
:10:01. > :10:03.And I think it takes a certain kind of person to give
:10:04. > :10:06.all that up and come over here and work for charities.
:10:07. > :10:15.Hello, and welcome to the week in tech.
:10:16. > :10:18.It was the week that Microsoft released an urgent software update
:10:19. > :10:23.after discovering a flaw in the windows operating system.
:10:24. > :10:26.The bug could give hackers access, by simply sending an e-mail,
:10:27. > :10:29.A 16-year-old's tweet about chicken nuggets became
:10:30. > :10:49.A US plane arrived after being top secret.
:10:50. > :10:52.Having landed at the Kennedy space Centre, all that the Pentagon
:10:53. > :10:56.declared about the Air Force's robotic mini space shuttle
:10:57. > :10:58.is that it was performing risk reduction, experimentation
:10:59. > :10:59.and concept of operations development.
:11:00. > :11:02.And, finally, Hollywood quality animation comes to the masses.
:11:03. > :11:10.The Smartsuit Pro with camera free motion tracking system costs
:11:11. > :11:13.a fraction of the pro kit, but at $2,500 it could prove game
:11:14. > :11:23.changing for independent movie-makers and game designers.
:11:24. > :11:31.That's it for the short version of click this week. The full version is
:11:32. > :11:36.up on iPlayer for you to watch right now. Next week will be rather epic,
:11:37. > :11:41.so find time for that. Follow us on Twitter and Facebook corrupt the
:11:42. > :11:43.week if you would be so kind. Thanks for watching and see you soon!
