So today, most turbines are well over 100 meters tall, with equally large rotor diameters. A turbine of this height and size can capture a huge amount of wind, generating enough electricity every year to power 750 American homes. A wind farm of...
“The power available to a wind turbine is based on the density of the air (usually about 1.2 kg/m3), the swept area of the turbine blades (picture a big circle being made by the spinning blades), and the velocity of the wind. Of these, clearly, the most variable input is wind spe...
Wind power offers another way to harness weather for energy production, and although they're not quite as common as solar energy systems, wind generators are actually more efficient. Wind power systems rely on wind turbines — windmills — that catch the wind with propeller-like blades. This tu...

But you really are as you’ve been told before, the equivalent of a sad old man riding an old nag with a bashed out “soap plate helmet” on his head as armour, trying to charge but failing to hit the sails of real world near idling windmills imagined in the deluded mind as feroci...
to harvest the mechanical energy of wind for providing mechanical power. Small windmills on farms power water pumps, and some were coupled to automobile generators to generate electricity on the farm before the electrical distribution grid was built. Now huge wind turbines provide power for that gri...
I don’t remember what they are called, but there are kite-based sails that have been invented to help save fuel for modern ships. It flies in a big figure 8 in front of the ship… and similar kite sails can also be used for power generators (as opposed to electric windmills). ...
Our forebears also cut down tall, standing trees with large-diameter stems – just not for firewood. Large trees were only “killed” when large timber was required, for example for the construction of ships, buildings, bridges, and windmills.4Coppice forests could contain tall trees (a “co...
Spend the next two days taking a day trip to Delos for more archeological exploration, discovering the charm of colorful Little Venice and Mykonos’ famed windmills, or splashing in the Aegean at fun-filled Ftelia Beach. On Mykonos, you can choose to sack out on the sand or explore the ...
Being a country girl from living on the farm, I do not feel as badly as I used to. Fed up. Tyvm!! Linda says: Thanks for the suggestions! This year they are vile little rascals, they have their hills in my yard, all around us in the fields and pastures. my cats are catching ...
