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

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
