WIND POWER; RATIONAL ENERGY INTO ELECTRICITY?
May 2nd
Question by malice:
wind power; rational energy into electricity?
how does wind power work?
i know that
the turbine blades capture wind energy and begin moving,
they spin a shaft that leads from the hub of the rotor to a generator
The generator turns that rotational energy into electricity.
but how does the generator turn the rotational energy into electricity?
please include a reference if you can.
thanks

Q&A: HOW CAN I CHECK IF MY WIND GENERATOR PRODUCES ELECTRICITY?
May 1st
Question by samc1994:
How can i check if my wind generator produces electricity?
I’ve built a wind turbine which i hooked up to a small generator i purchased off ebay for $ 20 bucks, and it did not specify how many RPM is needed to produce adequate electricity. So im wondering if there is a way to test if the two positive and negative wires coming out the back produce an electrical current. Does any one have any ways to check if it works? But i do not have one of those voltage meters which you measure stuff like that, so are there any alternatives? Please help. All answers appreciated!!
thanks

Q&A: WHAT IS THE CURRENT STATUS OF SOLAR PANEL INSTALLATION FOR HOMES?
Apr 29th
Question by jjttkbford:
What is the current status of solar panel installation for homes?
I keep hearing about new great progress in the field – then practical installation is still quite costly and life span of the solar panels is estimated at 10 years – not enough time to really make a difference financially
I’m in Southern California too – prime area
Please cite any sources you have re: new and improved systems that are ready to instal.
thanks – Solar seems like the answer – and I keep hearing we are getting close – just hard to be patient.

IF IT TAKES 10 MINUTES TO PREHEAT MY OVEN, WHAT CAN I DO TO SAVE ENERGY?
Apr 29th
Question by :
If it takes 10 minutes to preheat my oven, what can I do to save energy?
While it preheats, might I put the fish sticks in, or will they be mushy?
This is just an example. I realize that casseroles, baked potatoes, and such can be put in then, but what about the rest?
It is a 5 month old gas range. I seldom use the oven these days, but when I do, there are usually at least two different meals cooked as long as I am using the oven.
A baked potato is just not the same from the microwave as the oven.

HOW CAN YOU GENERATE ELECTRICITY FROM A ROTARY MOVEMENT?
Apr 28th
Question by :
How can you generate electricity from a rotary movement?
I comprehend that a rotary movement generates electricity
such as:
- Wind Turbines
- Hydro electricity
etc
What actually happens to transfer the (eg)wind energy into an electrical one
I also know it’s something to do with generators; but what is in a generator to give you a voltage?
