[Gasification] Wood Gasifier Alaska, Q & A

[Ken Calvert]

Greg,
 that is very interesting and obviously 25 years of progress on
what we used to do with two lightbulbs in series accross each phase.
One juggled the throttle until the moment when all the three pairs of bulbs 
were out, then you threw the switch!
If they are prepared to let you burn your own power first and then their's 
later
that means that you are getting the equivalent of full retail price for your 
power! Which is Great!
However, I am guessing that what power you do manage to export will be paid 
for by them at a much lower figure?
The next question is,  how do you govern your gas engine accurately enough 
to keep exactly in phase
with the grid?  Surely there must be a bit of lag or lead to hold your 
generator rather than your gas engine
accurately in phase??
Ken C,   whose living and learning every day!
