I just checked the Generac Generator site, and they do claim that there 8K generator uses 119 cu.ft an hour. So I guess the Honda Generator at 3/4 load probably uses 82 cu.ft. an hour.
Please double check my math, maybe its way off then??
There is nothing wrong with your math. I have no experience with natural gas - the only nearby sort-of equivalent is LP. I heat with diesel, and two of my neighbors with very similar houses heat with LP. It winds up being more expensive for them even though the cost per gallon is cheaper because of the reduction in BTU's.
I do know that the package co-generation plants use natural gas because it is far cheaper than alternative fuels. At .17/kwh for fuel costs, it would be be much more economical for you than some of the high-tier PG&E users down here. Hope it works out for you, and keep us posted.
I think you have a good idea here if you scrub and vent the heat in the house it would almost be enough to heat your house in the winter in the summer vent it in your sewer line

Ya, detach garage, so do need to figure out how to handle the heat, I mean there won't be a ton of heat running 3000W(Five 600 Watters in a Heath Style Tree Grow) but it still needs to be addressed, that really is the last equation...... Definitely thinking sewer line will be the only way to go?????
Anybody have any other creative ideas for getting rid of heat? My garage ceiling is vaulted so can't dump it in the attic. I would run the lights on cycle at night so there would be a little less heat to deal with than running them during the day when you have the building being heated by outside as well.
Spoke with the guys that make the Tri Fuel conversion for the Honda generator and they said I can expect the generator to be good for 4000-5000 hours. Much better than I thought actually. Even at 7 hours a day I could get 2 years from 1 generator. What I would do is just change it out every year and sell the generator. $4500 for a generator from these guys, comes with a 2 wire start so the generator will fire up on its own off of a trigger plus a auto primer so there's no issues with firing up on natural gas. After a year of use I bet I could sell it for $1500!!!! Transfer switch is about $1000 for a good one, that would last years, battery's I would only need about $3000 worth since they will never actually be taking any of the load on there own. $2000 for a good invertor/charger and $4500 for the generator. Total initial investment of $10,500 + tax + shipping about $12,000. That would be paid off after 1.5-2 grows(total of 11-12 grows a year)!!! After initial investment year, it should only cost me around $3000 a year after selling the used generator!!! not bad at all. Then after 5 years, once it's time to replace battery's you could work that out to costing another $3000 or $600 a year for 5 years. Pretty damn economical way for being stealth
Onto the next problem A 4 inch drain pipe for getting rid of heat. If the pipe is 125 ft long with two 90's and two 45's. How many cfm do you think I'll be able to draw from the room and what kind of fan?? Not sure if a 8" or 10" fan can be reduced that much without causing the motor to overheat???
125' that's long you must have a huge house I'd get a threaded joint for the cleanout then put a back flow preventer or plumb it up to the ceiling then have a fan and dryer flap to prevent gasses from getting in case of a shutdown. I'd run a few 4inch fans to keep it moving down the line and two 45s might be better than a 90 with fans pulling air from your room still use a scrubber and even test the sewer first by just taping a fan to the trap to be sure it works leave it for a couple of days.
