[Gasification] Where is Everyone? - 4 houses off grid

Tom M.,

The mention of 5000 hours/yr is an average of 14 hrs per day.   But how 
much power do they need?   Minimum expectations, average, and maximum 
and peak requirements are all very different.   If the 4 houses want 20 
kW each, that is different from power for basic LED lighting and fans in 
gas heating and a refrigerator running.   5 kW max and 3 to 4 kW 
sustained for 14 hours is withing reach.

What did your requester specify?    Any mention of the available 
biomass?   In what climatic region?    Summer houses in Wisconsin that 
are only occupied for 4 to 8 months are different from Alaska 12 month 
residences.

ANY size of operational system will find some people who will want it.   
Then the question becomes the price they are willing to pay.
