Dear Ronald
I was struck by the apparent parallel between "Classic Old Time Imperialism" in the Physical world, and "Technology Capitalism" in the "Stoves World." Examples of the "Classic Old Time Capitalism" would be of the Romans who conquered Countries for their Resources, and the Spaniards conquered the Mayans and Incas for their Gold, as compared to "Technology Capitalism", where a Member or Members of the "Stoves List World" seek to take New Technology, "The Gold of the Stoves World" from "lesser powers."
Imperialism is defined at http://encyclopedia2.thefreedictionary.com/imperialism Classic Imperialism usually involved exploitation of a smaller or weaker Country or people by a more powerful Government or Country, where "the Imperialist" takes labour and tangible resources from the Country or people it dominates. The parallel with "Classic Imperialism" is perhaps weak, in that neither Governments nor tangible resources are involved, but rather, Individuals and abstract Technology.
Perhaps my parallel was "too big a stretch." What do you think?
Best wishes,
Kevin

Dear Kevin,
Please define "Imperialism" since it's not clear from the context what you mean.
Thanks,

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
