Answer by William Shanker
…most likely NONE as the cost of a wind-generator and everything involved in its construction and set up is ENORMOUS !

Answer by PointBlankResponse
You need like a thousand more points of detail in order to answer this.

-How huge a house/how much energy do you use? how much are you paying?
-where you get the turbine? how huge is it? how much energy does it generate a year?

Answer by Mohammad
Wind Turbines are costly and need a massive area to be constructed.

A 20kw wind turbine will cost you at least 80,000$ .

So, I think you save NONE!

Answer by Dolphin lover
Wind can turn a wind mill, which generates electricity.

And flowing water can produce hydro electricity. (that, you will have to look up)

Answer by October
They can turn a generator that produces electircty.

Answer by sideways
This has to be for homework right?
Wind turbines produce electricity by turning the engine

Answer by sp33dstix
Well it is possible and I am sure people have done it before. Only problem that I can see with this is to prevent power surges to your ipod. Also if you do construct one of these make sure to MATCH UP THE VOLTAGES~
If you do not there is a potential(no pun intended) to do some huge damage to your ipod.
Try to look up some circuits used for solar panels to prevent these surges.

Here is someone who has done it before:

http://www.reuk.co.uk/Solar-iPod-Charger.htm

It is a really easy circuit that uses a 6 volt solar panel and a voltage regulator to get it down to 5 volts.
Google:
“diy ipod solar charger”
for more info.

Also to improve on your design, I would KEEP the original ipod cable AS IS and use a femal usb port in the circuit. That way you can use this solar charger for any usb device.

Why waste a perfectly good over priced IPOD cable?

Take Care !

Answer by Brad W
yes, i have used a colapsable solar panel to charge my cell phone and it comes with a usb adapter so im sure you could charge an Ipod with it.

With the right way of hooking it up, a windmill can be used to do both those things, and it’s (obviously) powered by wind.

Answer by Shereef
Windmill is the answer as it works by wind power and can both generate electricity and pump water

Answer by kris k
No, it is not possible. The act of putting wind turbines in a train would create an enormous amount of drag. This drag would add more required work to the train than the generators would even be able to create. The only logical way this would work is with retractable turbines that could be lifted when the train is trying to slow down. Since the train has such an enormous amount of momentum the turbines would help the train slow down faster and generate electricity for the next begin up.

Answer by HerbalPhil Wellness Warrior!
yeah yeah, I was being sailed in the whittsundaes before that horrid typhoon yasi and like the captain of the yaught is going away from where we are going for the night and so like I say:
“Now hey mad dude where are we going for the evening?”

“There” he stated looking rather agrieved as we headed into the wind like about 60 degrees from where we were headed???
And now keep in mind the dude has totally NO sense of humour and his mrs was below deck cooking the meal for when we arrived in a coral bay infested with coral flees for cleaning the skin after a sweaty day?
And I love living dangerously and said,

“Now where are we going?”
Getting rather frustrated and uptight he stated there pointing fair enough to where we were headed/

So I am thinking really cool like to learn a lot about sailing the way Bart Simpson would without the continual repeating of verbosity?

“So if we are going here, and the evening stay is there” As Miss Sweden sunned herself in her tiger print swim suit and the lovely Swiss coupled laughed on deck newly engaged.
“Why are we going there?” As my really daft Aussie mate laughed his guts out who knew a thing or two about tacking and my lack of tact?
“I am gonna throtlle you???” Still didnt explain his apparent need for violence whilst the crew were belwo deck on deck and he did everything so I said
“So if we go here and have to go there by here what are we seeing there?”
He did not vaguely answer this but fused on an angerfest deep within it wasnt a Sydney to Hobart, the Solo had won a few or been in it at least three times?
Sheez no sense of humour I thought!!!

So if you want Sydney trains to run on time, the moral of the story, dont let me get the driver angry when we are going to the City via liverpool from Richmond when we set sail?

Answer by Nightwind
No,not possible.
The wind hitting the surface of a train is nothing compared to the wind resistance pushing against the surface of the train. Not to mention that its this same wind pressure pushing on wind turbine blades that causes a turbine to work in the first place. Just how do you propose to get a train initially started ? Wind turbines, despite the uphoric BS you have heard about them, do not produce enought power to run a train. mechanically there is too much friction to overcome to make enough current to run a train or power the motors, and each time you convert energy from mechanical, to electrical, to stored electrical or step up the voltage or step down the voltage……..you lose that much more in the conversion process.
L rails use tons of current, the likes of which a wind turbine could never generate enough of. And regular trains efficiently use diesel fuel, which outdoes wind energy.
Look at how many decades we have been ‘dabbling’ in wind energy, and how much this day does it produce for the grid power we all depend on ? less than 5%. Most places are tiny over 1%.
Those statistics along should have made you think that wind itself is not that reliable or great a renewable source.
Forget that stupid tiny girl on the wind energy commercials playing with her tiny sail boat at the beach, wind is a pipe dream and we should stop wasting the real estate on such projects and find something more sustainable.

Answer by Kinshuk
used in rural places for winnowing

Answer by doug_donaghue
It is frequently used to drive water pumps. That is what all of the windmills on farms are usually doing. It’s also used a bit to drive grain crushers (to make flour out of wheat).
And it is totally vital for getting politicians elected ☺

Answer by Amerson
water wheels worked as pumps for irrigation , which was animal powered.
Wind mills , had common usage as Grinders for cereals.

Answer by The Oracle
Yup – indeed they were. Wind “mills” were used to grind wheat into flour, as were water mills. Many towns in England still have a “millpond” and “millstream” where the flow was diverted from the main river and sent to the mill.

Old watermills can be converted to generate electricity through relatively easy modifications using the original water wheel and gearing, but with the power going to a generator and a battery bank instead.

Answer by paducahbill
They were used as sources of energy also, water will would turn a mill and grind corn and not product electricity. So yes, they were used as sources of energy. Wind mills were used to pump water.

Answer by Jeffrey F
Coal: Very good heat source but produces carbon, sulfites and particulate pollution. If burned at higher temperatures, this pollution is reduced, but not completely. Waste product is ashes, which do not break down as they are already broken down……finding its way into concrete recently as a bonding agent.

Wind: Good, as it is renewable and does not produce pollutants while creating electricity.

Solar: Also renewable, but manufacturing of the solar panels cause pollution

Nuclear: Very efficient at creating steam for steam turbines which in turn create electricity……..waste product must be stored for thousands of years before it MAY be made safe by the radiation running out….No one knows how long this stuff must be stored and maintained…….final costs are unknown and might never be known

Oil: there is only so much accessible oil in the ground. It is only a matter of time until this raw supply is used up. Creates particulate and carbon pollution.

The only sustainable electricity generation is wind and solar. Is it good, none of it is good, but it is all, unfortunately, necessary to keep our economy running.

Answer by frflyer
I pretty much concur with Jeffry.

Except with the comments about solar manufacturing producing pollution. While that is undoubtedly true, why single out solar? Pretty much everything we make has some environmental impact.
Wind turbines too. Carbon fiber blades must have some impact in their manufacturing for instance.

Solar thermal power plants might have less impact in their manufacture than PV. It’s basically glass and steel, with a generator of some type.
(turbine, stirling engine for example)

At any rate, both wind and solar have small impacts over the life of them, providing absolutely clean energy once they are installed.

They both have advantage of being able to be built in relatively short times, compared with coal or nuclear plants.

Mass production of plug in hybrid automobiles in the U.S. would save lots of oil. They are more marketable than pure electrics, because they have no range limitation. The average American driver would get overall mileage of 100 mpg. Recharging at night for $ 1 of electricity.

Plug in Partners – advocacy group for PHEVs

http://www.pluginpartners.org/

“Charging the battery each night would cost less than $ 1.00 at current rates. PHEVs outfitted with a battery pack providing a 40-mile electric range could power, using the all-electric mode, more than 60% of the total annual miles traveled by the average American driver. That means tens of millions of motorists could make their daily commute using little, if any, gasoline. ”

“PHEVs would result in significant fuel savings for most motorists. The initial cost of the plug-in vehicle, however, would be more than a conventional automobile or one of the existing mass-produced hybrids. However, a 2004 study by the Electric Power Research Institute (EPRI) found that plug-in hybrids can achieve life cycle costs parity with conventional gasoline automobiles – meaning that over the life of the automobile the cost will be equal or less despite the initial higher cost. The study calculated gasoline price as $ 1.75/gallon.”

So at $ 4 a gallon which we will see soon, how much would you save?

Using the grid to charge automobiles at night is already cleaner than burning gasoline. As we make the grid cleaner, PHEVs and EVs will make more and more sense.

Answer by crash
coal, nuclear & solar or hydroelectric generating facilities are massive & require a massive amount of land so they are fixed in one location(except for nuclear powered ships).
oil & gas engines concentrate a lot of energy in a small portable package so it is more sutable for transportation.

Answer by Keith
you are safe to use the CFLs bulbs. One of the good things about them is that they do not give heat ( as a waste byproduct ). So go ahead and use them worry free.
I have used them for years and my power bill is always lower than my neighbors even though we have a larger house.

Answer by Tex
If the wattage is less then the heat is less. The CFL’s equivalent light out put is higher that an incandescent, so actually if you select a cfl with the same wattage rating, you will get a lot higher light output. However doing this will not save any energy and will not cost less to use.
The other answer is totally WRONG, cfl’s do produce heat, just not as much. It all depends on the wattage rating. 100 watts will give off 100 watts worth of heat, no matter what kind of bulbs.

Answer by William B
the newer bulbs put out very tiny heat,
the rating on a light fixture is for a incandescent bulb that puts out a lot of heat,
so a 60 watt bulb will put out more heat than a 40 watt will
you can put a 100 watt fluorescent bulb in a rated 60 watt fixture and still be safe,

Just pulls a pn junction. So positive and negative are requried.

Answer by Wayne
We kinda gotta know what that something is, and how huge the solar panel is. I can’t run my automobile on the solar cell attached to my calculator.

Answer by Irv S
First choose a ‘something’ that takes the DC voltage,
and can operate on the amperage produced by your
solar panel.
Then hook it up, place the panel in sunlight, sit back, and watch the fun.
