Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
The guys from google have developed a power source the size of a parking space that could produce 100kw for a minimum of 10 years. The price is a little steep at $800,000 or $400 a kw. They say they are trying to get the price down to $3000 for a home size unit. Article here

"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen."

$50million
7-10 years of power
20k homes
Its basically a self contained nuclear battery buried and connected to a steam turbine.
rural/military applications hmmmm!
WE live 3 miles from utility power. Been living off-grid for 5yrs. Power our home with a wind turbine and PV. Installed the system myself.
Glad to answer any questions regarding wind turbines and PV.
I assume the wind turbine and PV setups are all tied together? Did you build the WT yourself or was it purchased? Cost and output of the WT setup?
Yes, wind turbine and PV is tied together charging the same batteries. The wind turbine I purchased is a Proven WT2.5. It is on a 70' freestanding tower. Picked the the Proven for it's reputation of surviving harsh wind sites. I have a harsh wind site. Last January had a peak gust of 102.6 mph. The turbines peak output is 2800 watts @ 30 mph. Last January with a average wind speed of 15.6 it produced 636 KW hours. The cost, 18K doing all the work myself.
PV consist of 2200 watts of panels.
Between the PV and the wind, it produces more than enough to cover our loads. Also have 12KW propane generator for a backup.
Welcome to the forums. That's a lot of power. 24V I take it? how many AH of storage do you have?Originally Posted by offgrid
I see you running, tell me what your running from
Nobody's coming, what ya do that was so wrong.
48 volt system. The advantage to 48 over 24 is lower current, smaller gauge wire $, single series string of batteries.
1180 AH battery bank, 24-2volt cells. A nominal 50V's x 1180 = 59, 000 watts capacity. We use about 8 KW's a day. Battery bank gives us 3 day storage discharging down to 50%. Very rare to go 3 days w/o sun or wind.
