Thomas asks…
Is the Nanny Pelosi plan for energy an old Volkswagon with a sail attached to it? Small cars, wait for wind?
Do Demorats do a good job at prevent democracy from occuring by preventing important votes from occuring?
The House adjourned for five weeks to attack Democrats for leaving town without doing something to lower gas prices… “Madame Speaker, Where art thou?” Rep. Ted Poe, R-Texas, shouted from the well of the House.”
Rep. Devin Nunes listed all of the GOP bills that the Dems killed.
He then said, “I am a Democrat, and here is my energy plan” and he held up a picture of an old VW Bug with a sail attached to it. He paraded around the House floor with the sign while

Wind Energy Question? Why do the wind mills have only 3 small blades?
I know that this is an older model but why 3 small blades. Why not 5? 8? I have a theory and I hoping to prove my dad wrong so let me hear your answers.
Here’s a picture of what I’m talking about.

adminsta answers:
Windmills with a high number of blades move at high velocities, and low amount of torque. The high velocity of the blades creates a lot of turbulence and drag, which is inefficient. In moderately high winds, a large number of blades can cause cavitation, which is a situation where turbulence ends up stopping the flow of air across the blade. The large, 3-blade models have very little drag, they have high torque needed to turn electrical generators, and they can operate in extreme winds without causing cavitation.
Mandy asks…
Why does T. Boone Pickens need my “help” to launch his wind energy “business”?
I’ve never had a business man ask me for help to start a business before. They typically just start them, then charge me for the product, make a profit, and pay taxes on their profit.
What’s different about this “business”? Why doesn’t he just start the business, like all other businesses?
If he needs my help, is it really business at all? If he needs the public to help him, shouldn’t the public just cut him out of the picture and do it themselves?
what other perks will he get? water rights, etc?
even people in his own state say he has a history of scamming taxpayers
adminsta answers:
Because his plan requires changes to the law… It requires a massive shift in the mind-set of America.
At no point is he seeking FISCAL backing from you… He’s seeking people to help PUSH the program.
Just FYI, he is the FIRST to push a NATIONAL program to reduce BOTH our National debt, our Oil usage, and Green-house gas emissions.
Mary asks…
Where can I get a cute cartoon of wind being blown?
I’m doing a poster about energy of wind, and I was wondering where I could get a picture of a cute little cartoon cloud or something of wind being blown? Thanks a lot!
adminsta answers:
If you are doing a big cardboard poster, it would probably be easier to draw it. Wind is not that hard to draw. If you still want an image, try going to Google and doing an image search (i.e. Click on “Images” at the top) for “wind clipart”. (You might also try “wind clip art”.)
P.S. Someone explain to me how a video on YouTube will help you get a clip art image for a poster?
Carol asks…
Wind turbine model relating to chemistry?
We are said to make a chemistry model and I’m planning to make a wind turbine which converts wind energy into electrical energy
Our teacher said that we can choose this topic but said to make it somehow a little related to chemistry
I’m planning to make a Vertical Axis Wind Turbine ( VAWT )
I will be making the model from these site addresses in which the instructions are given :
http://www.re-energy.ca/t-i_windbuild-1.shtml
http://www.re-energy.ca/pdf/wind-turbine.pdf
It is a simple model in which when the turbine moves ( the big plastic thing in the middle of the Generator in the picture ), the movement is converted to electrical energy which lights up the LED light
Please tell anything which i can add to my model so that it relates to chemistry somehow
even suggestions of putting some chemical substances on the turbine to move it smoothly or some other topic on chemistry with references or anything relating to that will be appreciated

Help determining the ratio of total kinetic energy due to rotation?
A puck rests on a horizontal frictionless plane. A string is wound around the puck and pulled on with constant force. What fraction of the disk’s total kinetic energy is due to the rotation?
Picture: http://i284.photobucket.com/albums/ll28/bathtub2008/showmepl-6.gif
KErot/KEtot = _____
adminsta answers:
I hope this will help u.
rot/total=1/2 IW{square of IW} UPON
1/2 MV{square of mv}1+K/R
=MK V/R[UPON]
MV{1+K/R}
ex:- when a disc rolls without slipping down a smooth inclined plane, the ratio of its rotational kinetic energy to its total kinetic energy is given by this formula.
I hope u know the basic of rotational motion.
Also when the puck is at rest K.E energy is zero.since it is pulled slowly the puck is rolling and not rotating.
George asks…
Science Project Help?!?
Can you answer the following questions?
1) What is wind‘s original form of energy?
2)What form or forms is wind changed into so it can be used?
3)How does wind cast compared to other energy source?
4)How plentiful is wind (how much is there in the word)? Where can it be found and used?
5)What are the main advantages of wind‘s energy source?
6)What are the main disadvantages of wind‘s energy source?
~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~~*~*~*~*~*~*~*~*
Give any other interesting facts if you find any.
Thanx. =^_^=
P.S. If you find any pictures of wind, can you give them to me?
Thanx. (Again)=^_^=

Lisa asks…
Will massive numbers of wind turbines eventually impact our climate?
Sometimes, I picture a drive in the country (perhaps a few decades from now) where immense “farms” of wind turbines stretch for miles on both sides of the highway, kind of the way wheat does on the prairies, today.
Would this kind of a scenario gradually have some sort of an impact on the global climate? Technically, energy is being transferred from the atmosphere to the turbines. Would this not cause slower and slower wind speeds? Or maybe atmospheric temperature would drop? I suppose the general argument is that it eventually it gets transformed into heat somehow, and then released back into the atmosphere? I dunno, any experts here?
adminsta answers:
If you had really massive amounts of them everywhere in sight and over large fractions of the ocean then you might see a small reduction in H2O ( a greenhouse gas) content in the atmosphere as they will tend to reduce evaporation by reducing average wind speed over wet surfaces. You will have to cut down most of the trees to maximise the area in which windmills can be sited and this will also tend to reduce atmospheric H2O content but will probably slightly increase atmospheric CO2 and methane levels (I’m just hand-waving here obviously – I don’t have any numbers). At the moment a lot of concrete is used in windmill construction and that causes release of fossil CO2 into the atmosphere but I suppose you could postulate building part of the support masts out of recycled hydrocarbon waste instead and so lock up as much as you are releasing or maybe more.
