So much depends on where one is located in determining the benefits of
mass-production.

Here in Vietnam a skilled welder received about $100 US per month. But even
at such a low wage, this welder cannot compete with  mass-production
equipment that can make thousands of parts in a day. I think that a day is
coming soon when high-quality gasifiers will be situated in many households
in Asia. Bottled gas is getting too expensive, and people to not want to go
back to burning low-grade biomass. So we must have the means to make a lot
of units at a very low cost using quality materials. Also I intend to
supply hard-to-make parts to workshops so that they can get units out the
door in an efficient manner.

Similarly when we turn to China to buy fans, we get a far better price if
we buy 10,000 fans instead of 200. This is the logic of mass production. It
makes it possible to produce quality items at a reasonable price for a
large number of people.
