Clean coal

Achieving the reality of 'clean coal' by doing scientific research and development, might be as difficult as putting a man on Mars. How would we ever colonise Mars, if we get there and find there is no coal on the planet ?

How about clean air and water instead?

Trump proves how the very rich can, at the very same time, can be totally stupid.

What really makes me laugh, is that some people talk about 'clean coal' as being an established process. They base suggestions for sustainable eco-friendly electricity generation on it. I'm a scientist, and I still haven't heard about the break-through. Yet the arm-chair experts all know about it.

Don't know about clean, but you can polish it.

Somehow . . . . . :idea: no one is worried about the millions of tons of CO2 released from Diet Coke and plain old beer. :shock:

The Greens should push a "flat beer" movement.

Apparently the moo-cows are a major source of methane emissions ? - Still wouldn't induce me to become vegetarian.

yes acotrel, there were people/farmers in the past who put a kind of balloon above the cow shed in order to collect the methane gas, it soon came to nothing when someone set this alight with a lit fag :!: :shock:

Not too long ago I wondered why coal wasn't being molecularly broken down into the same fractions as crude oil. Well, it is (can be). The issue is high CO2 emissions that evolve during the process(es). Capturing and stabilizing the CO2 makes the process too expensive, and with the amazing abundance of natural gas in the US (that can be polymerized into any length carbon molecule you'd like) makes coal a fossil in many more ways than one.

I was captivated by the movie "The Formula" with George Scott and Marlon Brando, where Brando, as a Big Oil Fat Cat, tells Scott that during WW II the Germans didn't have crude oil, but they had plenty of coal...For years I wondered whey Big Oil didn't capitalize on this, turns out that the Germans did not have a catalyst that could break coal molecules into anything useable. The ME 262s ran on a slurry mixture of coal.

I did hear a rumor that the South Africans are actually converting coal regardless of the CO2 emissions, ' can't say for sure.

The usual way of capturing CO2 in industry is to turn it into sodium carbonate using sodium hydroxide solution, however I think the sodium hydroxide is made from sodium carbonate by burning lime.

No need to change, we (humans) have a very different digestive process and gut biota and as a result our main by-product is hydrogen which is not a greenhouse gas.
