[Stoves] Very small stoves and reheating food

[Paul Anderson]

Crispin and Alex and all,

Successful "dribble" or "trickle" feeding at very low cost will be a 
great addition to small stove technology.

Of course gravity is the least expensive.   But "assisted gravity" might 
be relatively low cost.   I am thinking of a small tapper or vibrator 
that can be set to giggle the fuel chamber periodically or when some 
sensor sends a signal.

Alternatively there could be some shape of rod that is inside the fuel 
chamber.  There are many ways to giggle/wiggle/twist/tap/lift/drop to 
have minor movement of the rod to assure the gravity flow of the fuel in 
the hopper.

Alex is doing it the right way:   Start with uniform fuels like pellets 
or quality (screened) wood chips.   When a method works there, then 
start looking at the more difficult fuels to make flow.
