Before anyone buys a portable wind generation unit, check to see if the local governmental authority allows such a unit to be erected on residential lots. It would also be prudent to find out if any home owners association with a say over your residential location even allows such a device to be erected on your property.

Thanks for sharing Eugenian.
Different locations have different resources available.
Assess what you have and make the best use. What a concept!

FROM THE ARTICLE:

A mid-size, portable wind turbine, called the Portable Power Center, from Uprise Energy, a San Diego-based wind energy company. The 50-kilowatt device is designed to provide affordable, practical electricity for remote, off-grid communities. Set-up requires one technician and one day; maintenance is minimal and done at ground level, according to Uprise. The energy produced is affordable, the makers say, less than utility, solar and diesel power.

cadillac said: "Someone below said, 'A typical home requires peak energy of up to 15 KWH during hot or cold weather.'"

A typical GROW house, maybe.

Sounds like this sort of technology could be used in disaster situations where utility power would be out for an extended time period. Earthquake, flood, hurricane, etc.

Could be used to provide emergency power for evacuation centers (shelters) or to power other emergency services (hospitals and the like). Being portable the equipment could be brought in by the National Guard wherever it might be needed.

cadillac, your description of electrical measurements is not quite right...

A 100 watt bulb does NOT use 100 watts in an hour. It is expending 100watts continuously. In an hour, it will consume 100 watt-hours of energy. In ten hours, 1000 watt-hours, or one KWH.

watts is 'rate' (Power)
watt-hours is amount used (watts x hours) (Energy)

The article claims that is turbine produces 50 KWH of electricity. More than most houses can use at one time. Be nice to know how much it costs.

OnEmptyMO, I'm absolutely sure of my numbers, as I had the bill right in front of me as I was using the numbers.

And when I was taking my electrical technicians course it was plainly stated what a KWH was.

A kilowatt is 1,000 watts, and a KWH is the number of kilowatts used in one hour.

Now you use the numbers I supplied for my 'very less than typical' August usage and you see what you get.

I was charged $45.00 for the first 600KWH @ 0.075/KWH, and a further $35.50 for the other 403.456 KWH @ 0.088/KWH, for total of $80.50 for the 1,003.456 KWH I used.

The numbers are all there for anyone that wants to try them.

Someone below said, " A typical home requires peak energy of up to 15 KWH during hot or cold weather."

If any house is using 15 KWH (15,000 watts per HOUR) that isn't a 'typical' house and they are using way too much electricity.

I think some people below misunderstand the numbers when it comes to electricity.

First off 1 kilowatt is 1,000 watts.

When any device expresses its wattage that number is determined by how much wattage is used IN ONE HOUR.

As an example, a 100 watt light bulb would use 100 watts IN ONE HOUR.

Therefor, if the wind generator is described as a " 50-kilowatt device" that means it delivers 50 kilowatts PER HOUR (50,000 watts every hour), each and every hour it is in operation.

My August electric usage was 1,003.456 KWH (kilowatt hours)and that was only because my A/C unit was running constantly because it was low on refrigerant.

But, even if we use that unusually high number, when it is divided by the 31 days in August, it comes to 32.369kilkowatt hours PER DAY.

And, if you further divide that up by 24 hours, you get 1.348 kilokwatts (1,348 watts) used PER HOUR, so the wind generator could easily deliver enough electricity to power 15 homes with an output of 50 kilowats PER HOUR.

Like I said above, if any house is using 15 KWH (15,000 WATTS PER HOUR) that isn't a 'typical' house and they are using way too much electricity.

They would have to have every light and every electrical device they own going all at the same time for that whole hour.

You notice, every time there is an article announcing a save-the-world device, never is cost mentioned, nor where-you-can-buy-it.

Claims that it can power up to 15 homes is exaggerated. A typical home requires peak energy of up to 15 KWH during hot or cold weather. That would mean a total peak demand of up to 225 KWH. The wind turbine only produces 50 KW. Where is the other 175 KW coming from?
