I like the Idea of off grid power, I think everyone has a point here, but with the proper precautions it can be pulled off given the right location, property etc.
If your gonna be dropping that much $ on a genny Im sure you'll be able to find a way to hook you up with diesel in a low key fashion.
Buy a 1000 gal res, bury it and start filling way before you do your op. I dont know about running it 24/7 unless you have some serious land even then you always run the risk of it taking a crap on you like fishwhistle said. Then your royally fucked trying to get another 25kw genny lol.
Good luck with it bro, keep us posted
Heres a post from OBS back in the day on Gennys
"multiquip whisperwatt ultra silent 25kv $$$$ .. the very best generator and least noise
60 days running 15k will run around 950=1100 gl
i recall figuring aprox $193 in fuel cost to produce 1lb
bigger generator had a lower operating cost per lb until you go up to the 80kv then costs went up . the 70kv was most cost effective but uses 2x fuel but runs more than double the light of the 25kv ... i recall the 70kv runs $148 in fuel per lb ..
these are rough but close number but figuring running at 75% capacity , now the 25kv is rated to only be able to run 9k watts in it's amperage rating but in reality we have run 20k watts on the 25kv genny .. the key is the start up you need to set it up to fire only a few ballast at a time until all are on .... hid draw their biggest amps at start up so ... nowirenuts.ca can build a sweet lighting controller to do this"
