How to slow climate change for only $15B

[bik0]

Great idea...

Weaning humanity from its fossil fuel habit will take decades, and it will take decades more for global warming to stop. But one simple measure could slow warming in some of Earth’s most sensitive regions, effective immediately — and it would cost just $15 billion.

That’s a rough price tag for providing clean stoves to the 500 million households that use open fires, fed by wood and animal dung and coal, to heat their homes and cook. Those fires produce one-quarter of all so-called “black carbon,” a sooty pollutant that’s adding to the planetary heat burden.

“We know how to cook without smoke,” said Veerabhadran Ramanathan, a University of California, San Diego climatographer. “A clean stove costs $30. Multiply that by 500 million households, and it’s only $15 billion. This is a solvable problem.”

1. But you have to wait YEARS for f***ing Sears to deliver them. nt

2. Picture here of the Ecocina Stove:

:P

Of course, solar ovens are good to for many places...

3. Also very effective in reducing particualte pollution that significantly effects the health

of the populations using open fires for heat and cooking.

4. Very nice.

But it's still burning wood.

That's why I like the pilot programs that have been taking place in places like India and Africa, where the village sewage is turned into methane and piped to cooking stoves.

It's a much cleaner, more elegant solution -- eliminates human/animal waste (potential source of disease) and provides clean gas for cooking and even generating electricity.

5. Ecocina uses 60% less wood - reduces carbon output by 70%

After an exhaustive investigation of the cultural and technological factors surrounding open fires, the new, fuel-efficient Ecocina stove was developed by StoveTeam International. It is economical to build and operate, saving up to 60% of the wood currently used while also reducing particulate matter and carbon output by 70%.

6. Oh, it's *definitely* an improvement!

I'd never say it isn't. And it's a wonderful step in the right direction for those places that have an adequate wood supply available (though many don't).

It's just that trees and wood have other value, as well -- whereas human/animal waste must be disposed of, and biogas manufacture accomplishes more than one goal by transforming it to good use.

I'm just one of those people who is always looking for multiple-function systems. :D

7. Eco stove, methane digester, YES

just do it, get on with it and hurry every chance you get.
