I point out to the hon. Gentleman that the technology is truly tried and tested. The curious scheme in Northern Ireland aside, I would urge both hon. Members from Northern Ireland, who are my friends, to read the Oxburgh report and contrast the less than £85 kilowatt-hour that is achievable under this system with the Hinkley Point strike price of £92.50. Furthermore, the networks already exist. That is the attraction of having an existing infrastructure.
