The Mayon Turbo Stove is the first commercially available stove I saw that used a tap to feed and there are some complaints about the need for attention to keep it going, partly because of the rice hull fuel being so light and low power. The possibility of using another feed method is attractive.
So I am looking for a way to use the burning of the fuel right at the hopper outlet to do the job of releasing fuel now and then or 'often'. It doesn't look good at the moment but it might! Never assume anything. Alex I am booking to see you mid Nov as I have to collect a piano from the Carrying Place area.

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.
