I would like to help people have honest and constructive conversations about energy. We need to understand how much energy our modern lifestyles use, decide how much energy we would like to use in the future, and choose where we will get that energy from.

Fridges can be modified to nudge their internal thermostats up and down just a little in response to the main's frequency in such a way that, without ever jeopardising the temperature of your butter, they tend to take power at times that help the grid.

The toughest trail I ever ran was the Escarpment in the Catskills of New York State. This was an 18-mile race through Rip Van Winkle country, routed through boulder fields, across angular juttings of granite and along a path with an unrelenting barrage of roots, rocks and mud, all of it hidden under slick leaves and dangling nettles.
