Mr. Comeau,
Thanks for your response and willingness to continue this dialogue.
I would like to ask you;
What is your take on the basic concept that I am developing; that being to
design, develop and offer internationally a basic furnace design that can be
made in any country and then used to convert solids from sawdust sized
particles to large bales into heat, power or biofuels using direct
combustion, pyrolysis and/or gasification and be scaled from small to any
size needed and be operated by manual or automatic means as desired?
I see this as a novel approach to empowering humanity to rapidly adjust its
fuel mix from fossil fuels to renewable energy to address sudden climate
change (before it is too late) by building tens of thousands of small,
modular and widely distributed power plants and biofuels producing plants in
developing as well as developed countries.
In other words I am undertaking to put one more tool in our collective tool
box to fix climate change through also empowering the worlds poor to achieve
a better life through renewable energy in the process.
Is it already too late or should I keep trying?
Les Blevins
