On Tuesday 3 December at 7pm I’ll be chairing a discussion at London’s Delfina Foundation about energy utopias, and the potential of hydrogen as a locally-produced sustainable energy source. Speakers include the artist Nick Laessing, Rokiah Yaman (Project Manager, LEAP closed-loop technologies) and Dr Chiara Ambrosio (History and Philosophy of Science, UCL).There may also be food, assuming Nick’s hydrogen stove behaves itself.  More details here.
