So, say you use 2 2'x30' planks in a reverse wedge > facing the ocean say on the top roof line of a beach house. then under the hinged planks line them both with piezoelectric plates. use springs to bounce the plates resisting the force of the wind creating energy for the house. Feasible? how much energy
could be produced and how much would the piezo plates needed cost? This could be an alternative to wind turbines because there is a limit in height beach houses can go up (well in California anyway. This would only extended less than 3 ft. above the square roof line or could be built into new homes.
Just wondering on the feasibility of this.
your idea reminds me of this nifty wind generator [xaviergisz, Dec 15 2008]
||//Feasible?// I don't think so. You are suggesting planks with one end attached to the roof of a house via a hinge and the other end sticking into the moving air, with a spring holds the plank upright. If the wind is steady, the plank will quickly stop moving-- the plank must move against the wind, losing energy, when it returns to upright. When the plank is blown down, it gains energy, but to stand it up again requires the same amount of energy. If the wind varied in speed a lot, and parts were very cheap, this might work.
||Please take a crack at it yourself before asking me to figure it out. Try wikipedia/google to find out cost, size and power output information for the mechanical components and information about wind blowing across a wedge, etc., and post your best guess.
||Eh. You're much better off trying to harness the tidal energy. Seawater is about 850 times the density of air.
