Wind Energy Without the Blades?
What if we could harness wind energy without the fields of enormous blade turbines that have come to be associated with modern wind farms. It would certainly help eliminate the “spinning blades of death” that many birds have to deal with, as well. Levant Power of Cambridge, MA turned to nature for an inspired alternative:
The proposed design calls for 1,203 ““stalks,” each 180-feet high with concrete bases that are between about 33- and 66-feet wide. The carbon-fiber stalks, reinforced with resin, are about a foot wide at the base tapering to about 2 inches at the top. Each stalk will contain alternating layers of electrodes and ceramic discs made from piezoelectric material, which generates a current when put under pressure. In the case of the stalks, the discs will compress as they sway in the wind, creating a charge.
Not to mention that I wouldn’t mind having one of these near my house at night … just beautiful. If this doesn’t work, then all we have to turn to is purple turbines.

If Hoyoung Lee’s concept printer becomes reality, you’ll never throw away another pencil stub and never buy another ink cartridge. The pencil printer separates the wood from pencils and uses the lead to print documents. There’s even a built-in eraser component that allows you to remove text from a page and reuse the paper, so you’ll be saving money and trees.
