Dear Anil
Sadly, it looks like Imperialism is still alive and well.
Best wishes,

*Dear Prof Nurhuda,*

*It is a very impressive development and you are right in
expecting a suitable rate of return on your intellectual property.
Such requests for waiving rights have also been received by us for
our ethanol stove work before from some members of the group.*

*All the best.*

Dear Prof. Anderson,
The equipments used to produce the stove are actually the standard
equipments used in the kerosene stove production. They are
hydraulic
press, welding equipment, roller, and still many other equipments.
The number of personals are 30 persons, but those are involved
in the
production, due to still lower demand, is only 6-10 persons.
The maximum production capacity, at moment, around 500 units
in week. But
we can increase up to 1000 units in week. It depends on the
difficulty
level, the stove dimension and still many other things.
The expenses used in the development of new stoves are mostly
for research
and purchasing or build new equipments. We have spent more
tens thousands
US$ from our start in the mid 2008. I therefore disagree to
any proposal
to intelectual right removal, as you ever wrote about it to me
two years
ago.
Kind regards
M. Nurhuda
