[Stoves] Philips Stove. Was Re: Jatropha press cake as a fuel

[Paul S. Anderson]

Dear Paul v.d.S.,

Thanks for the info, and I have now seen Dr. Karve's comments about cost
estimates.  The number US$35 (approximate and estimate) sticks in my 
mind.  The
Reed Woodgas Campstove is sold on the Internet for $55.  But Tom R. mentioned
recently about possible manufacturing in India.  (Can Tom R. please elaborate
about that.)

I do not doubt the usefulness of the TEG.  I just stated that we have not seen
the stove unit with the TEG incorporated.  Because the TEG can be damaged by
high heat, I am curious about where it is positioned in the stove.  The 
website
info does not show that, from what I have seen.  Can you tell us about that?

Also, there was mention of Philips making proprietary claims (patents or trade
secrets).  Can you tell us briefly what aspects of the stove are being
protected at IP (Intellectual Property)?

Good to be in contact with you directly.

Paul A.
