CocolicoEach day, one green design.

Before creating something, check what’s already there. Make observation of your surroundings, try to mimic it. Obvious and timeless approach to design, but still true, still great. We’ve seen it with the duck-style solar plant that floats on the water, and dive its head whenever winds get too strong.

At BioPower, tidal power engineers have done it too. And they come with these two mechanical fishtails able to convert ocean energy to mechanical energy via oscillation about a single axis.

BioPower bets on the low-speed large-torque oscillations to generate up to 2,000 kWh in ideal conditions. It’s still lower than a wind turbine production, usually located in the 5,000 to 10,000 kWh range. But it offers a more steady output and shows higher environment integration. (via worldchanging)
