This Saturday, March 27th, many of us will turn off our lights for an hour to manifest our hope for a more sustainable future. We call this event Earth Hour
I have a dream; I dream that one day, we can celebrate a sustainable future instead of just hoping for it. In every city of decent size, all lights are dark, except for at the main square. The festivities on the square are powered by a fuel cell running on hydrogen. The scene is bathing in light from LEDs and a young boy is singing a song by Neil Young
. People are dancing in the streets, and the piezoelectric fibres
in their clothing are generating enough electricity to power their cell phones. Cell phone is the best word I can come up with, but this unit is much more than what we know as a cell phone. The interface is integrated in gla**** providing an augmented reality
Tonight, when lights are out and it's still winter in Sweden, my house is kept warm with the stored heat from my solar thermal collectors. Normally, the excess heat generated by people and electrical machinery is enough to keep the house warm. Actually, I can sell excess heat from the solar collectors to the district heating grid to warm older houses with less insulation.
