 I'm David Kingham, Chief Executive of Tokamak Energy and we're pursuing a unique approach to the development of fusion power. What we're aiming to do is to use spherical Tokamaks with high temperature superconducting magnets to make rapid progress towards that elusive goal of the electricity from fusion. And we're aiming to do that to the point of producing electricity for the first time within 10 years. One part of our innovative approach is the method of developing several prototypes rather quickly so we can try things, learn from them and build the next prototype. Making smaller devices does mean that there are different sorts of engineering challenges, particularly the magnet engineering but if we're doing things smaller, cheaper and faster then we can afford to experiment more quickly and learn more quickly and make more rapid progress. Got the 100 seconds in. It's very important to get the right culture in the company. We've got everybody pulling in the same direction and they're motivated by the excitement of the challenge, the excitement of the chase. We're taking on many challenges in parallel. When we do solve a challenge it often unearths further things that we want to work on very rapidly and this helps us to build up our intellectual property. We've discovered a lot of new information about these high temperature superconducting magnets and that's given us a unique intellectual property position which will be very important for the company in the future. We've been very fortunate in the staff we've been able to recruit and the advisors who've been willing to help us and some remarkably innovative people and we've been able to give them the freedom to think innovatively about the solutions that we need to accelerate the development of fusion energy. It's important to us to maintain flexibility and openness and we very much like to be part of a cluster of like-minded businesses. So far we've benefited greatly from the support of partners in technological and engineering solutions. We see the importance of that increasing dramatically in the future. One of the big challenges for mankind is to produce electricity without carbon emissions and fusion is one of the few options to do that on a massive scale and without using huge areas of land. We need a power source like fusion that will produce low carbon electricity in massive volumes if we can crack the problem as we intend to do within 10 years getting to first electricity it's going to have a huge impact on electricity supply in the world in the future.
