Will my 115V water pump get damaged from a 120Vac power source?

I have a timer system in place that takes in 120Vac as input power and i have it set up in a way to use it for my loads (water pumps). According to my specs my water pumps require 115V to operate. I notice there is a 5V difference in power being supplied and power requirements. So what happens? Will my pumps get damaged from excess power? My water pumps are submerged in my ponds when they are operating.

I need some input on Wind Power Generator Savings!?

Hi Folks,

I’m considering installing a wind power generator on my property as well as several solar panels. Where I live, I have hot water baseboard heating and an electric hot water heater. My property is well positioned for this type of application. I have 3 acres right by a lake and the wind blows 50 to70% of the time. I’ve got a local representative coming over in a few days to do a complete assessment of my property. My power bill is $320.00 per month. Can someone give me and idea of what your power bill or actual CASH MONEY SAVINGS IN YOUR POCKET have been as a result of installing solar applications on your property? I think it is a tremendous investment and I see only high energy costs for the rest of my life. I just retired and don’t like what I see. I’m looking at investing over $20,000 to get this done. This includes a wind power generator cemented into the ground. Does anyone have these wind generators installed on their roof? Thanks folks!

I am interested in wind power and its practicality in my area.?

I would like to find out cost vs. output, average wind speeds and generally how cost relates to the use of wind for private and comercial use. Any input would be appreciated.

free energy- 5 times more than input!

generator which creates 5 times more energy than the actual input.

In a wind turbine, what is the ratio of the input wind speed (to the turbine) to the output windspeed?

If we had 2 wind turbines one directly ahead of the other, would the wind exitting from turbine 1 produce the same power in turbine 2?

What are your experiences with solar power?

We are thinking about going completely off grid. Any input is welcomed. Thanx!
REAL “ADULT” ANSWERS PLEASE!!!

Richie..you make no sense..just say thanx for the 2pts and move along…
Wind isn’t a good option for us, we’ve checked the wind pattern map for our area..

Phyics confusing problems smart people only!!?
