If Alberta devotes even a portion of the brains, money and time it devoted to turning the oilsands into a useable resource to doing the same with solar, we might be onto something. Alberta has certainly taken a lot of black eyes for the way it develops its non-renewable resources, developing it's other greatest natural resource might be a way to address them.
The slow sway of the oilfield pumpjack, or nodding donkey as some call it, is one of the most familiar sights in Alberta. Drive around long enough and they become just another part of the landscape. But a small, innovative company based in Edmonton, Alberta named Canadian Control Works is re-imagining pumpjacks as green micro-generators. A pumpjack is like an iceberg. The vast majority of it is hidden, mysterious and out of sight. Underneath the pumpjack there are two to three kilometers of rod string which can weigh between five and 10 tons. Moving that weight requires a lot of electricity. Canadian Control Works is the group behind the Enersaver, a device which generates electricity from otherwise wasted kinetic energy created by the downswing of a pumpjack.
