[Stoves] Fwd: from K Smith [stove] Smoked out: Coal and health

[Jock Gill]

David,

I would like to agree with Paul and disagree, some what, with you.  Firstly, if there is too much CO2 in the atmosphere, adding more is intellectually dishonest.  Secondly, I agree with you if we do not also address the demand side for energy.  Too often we simply ignore the demand side. Why is this?

We also need new economics, politics, and social structures that accurately address the fact that we live on a finite planet with no external supplies other than solar energy.  Our current systems do not accurately reflect this simple, but inconvenient, fact.

Lastly, I suggest that you would gain if you compared and contrasted combustion vs pyrolysis. The term "burning" is too vague and fraught with opportunities for misinterpretation.

Regards,

Jock

Consider England, at one time it had huge supplies of wood, now there is little growing.  The forests were burned as fuel and used as masts for wind powered ships, the forests are no more.

Take all the "waste biomass" from the fields and suddenly there can be a problem which requires adding something back to hold and supply some of the nutrients.
