[Stoves] Questions to Paul van der Sluice

[Ron Larson]

Paul:
    1.  I have been off the stoves list for some time and so was unaware of 
the tremendous progress made by Philips and yourself.  I have reviewed all I 
could find on your stove - and see you have done a really admirable job. 
Congratulations.  Maybe especially for using the stove - as you describe 
below.

2.  I saw a Philips press release saying you would start sales this summer. 
Has that begun?  If not, when?  No price was then available.  What is the 
price or what is the present schedule for establishing that price?  Will it 
be available on some site for worldwide delivery - or restricted just to 
India or similar spot?

3.  Below you say your use is for "summer half-year".  Can I take this to 
mean that you recommend use only outdoors?  I have read your patent 
literature - and see discussion of using the stove for space heating.  Do 
you have models in process with a chimney or vent-hood?  I saw reference to 
Approvecho giving you a very high rating - anything new in this area?

4.  My own stove interest is now mostly on charcoal making.  Do you have any 
tests that might suggest you could achieve reasonable looking charcoal by 
simply inverting the stove into a bucket of water about half way through an 
otherwise normal run?  Does Philips have any interest in the "terra preta" 
area?

5.  I wonder what range of power levels (turn-down ratio) your electronic 
fan speed control unit has shown is achievable?  I like your establishing 
four modes for the fan/battery control.

6.  You have a really fine-looking thermo-electric generating system with 
battery. Could you expand on how large a watt-hour generation rating is now 
and what might be achieved with a stove of the size you have been 
developing - so as to place this form of decentralized electric generation 
into competition with photovoltaic generation?  Or are there reasons that 
one should not place the two systems in parallel - so as to be able to 
reduce the  panel and battery requirements of both PV and biomass?  You have 
mentioned a radio; how many hours of use have you found possible?  Or maybe 
put this answer into number of LED lamp-hours pr 100 grams of fuel?

7.  The name of your home town Eindhoven was dominant on this (stove) list 
10 years ago.  Do you have some personal association with that excellent 
work?  Is there any on-going stove work at Eindhoven University?

8.  In one of the sites found by googling, I saw your interest in carbon 
credits from use of stoves such as yours.  Where does that possibility lie 
at this time?

9.  I hope you will pass this note on to the appropriate managers of 
Philips - who saw the wisdom of getting into this area.  They are to be much 
congratulated for having a strong "sustainability" program and for 
supporting you in your passion.

Ron
