I agree. To make gas in one place and to transport this gas to another
place where the gas would be burned is very complicated. But this is not
what I am suggesting.

Again, I feel this this approach is too complicated.

Imagine that we load a small quantity of biomass pellets into a stainless
steel reactor no taller than about 8 inches (200 mm). A small fan with a
variable speed control would supply primary air at the bottom of this
reactor. An electrical coil producing infrared heat would be used to light
the pellets. The lighting would take place in less than 20 seconds and
would generate very little smoke. The speed of the fan determines within
limits the amount of gas produced. The turn-down-ratio is at least 4 to 1.
A burner is placed on top of reactor and serves at the same time as the lid
of the reactor. The burner produces a beautiful blue flame that resembles
that produced by a modern gas stove. When the process would be finished,
the fan would automatically shut down. The reactor is emptied of biochar,
and it is eventually sold as a soil amendment. It has a greater value than
the pellets from which it was derived. Such a stove could be operated
within a modern kitchen. Of course it would not be the only cooking
apparatus there.

I have not yet designed or produced such a stove.

But there are a lot of people on the stove list who are far more clever
than I.
They surely could make it happen.

Thanks.
