Giant windmills energize northern Philippines

Di aabot sa megawatt kada isa ata mga yan.

Eto Cut and paste

Wind Mill Efficiency
Windmills are turbines. The two names can be used synonymously. Turbines are a means of harnessing the a fluid's power (the wind) by converting the kinetic energy of the fluid (the wind) into mechanical power (the rotating shaft) When the shaft of a w indmill is hooked up to a generator, electrical energy can be formed. The generator can be used to produce either DC or AC current. Generators that produce DC can be connected to batteries, an inverter to produce AC, or to power DC loads.
Some generators are connected to heating coils. Generators that produce AC can be hooked up to AC motors such as water pumps. Windmills are NOT efficient. At the very most, a windmill can extract only 16/27ths of the kinetic energy from the wind. This is called the Betz Limit and it can be mathematically proven through calculus. Most of today's windmills extract about 30 perc ent of the wind's energy.
The Southern Cross farm windmill can only extract 10%.

Balak ko din dati kung magpapatayo ako house magiinvest kami sa solar panels and other renewable electricity para pwede mag aircon lagi hehe.

pwede kaya ako mag uwi ng solar cells? heheheh..meron nabibili dito..kaso yung mga nakikita ko 12volts output lang...pwede ko kaya gamitan ng step-up transformer para maging 220v?

ok yan sa mga lugar na windy. sa natl. geograhic meron water version niyan, kumukuha ng energy from kinetic energy produced by waves slamming sa shores. yun
ang mayaman tayo all-over the Phils. lalo na yun sa Pacific Side ng P'nas, Lamon Bay ba yun

kung poluted sobra masisira din yan puros basura papasok sa generator hehe.

Even if they're not fully efficient, they're extracting energy that's wasted anyway. I wish we had more!

nung mga late 80's i've already seen portable water turbines. basically the campers anchored it on a large stone in a stream, and then letting the water drag(and turn) the turbine. ginawa nilang power source for their campsite B)
