It seems that coal is trees that died ages ago and got buried but didn't rot. (and therefore didn't release their carbon content).
To reduce CO2 in the atmosphere and ,as a side-effect, produce coal for future civilations (human or otherwise), can't we grow loads of trees, but ensure we bury them
somewhere the bugs can't get to them ?

Sure you find out how to move the trees and bury them without using energy and destroying ecosystems and I'll bun this. |
|
| |
So basically we would have to ensure that we didn't pump out more CO2 in the process of cutting/burying trees than we are locking up in the trees... |
|
| |
I guess this is a long shot..... |
|
| |
The real trick is to plant more trees so that at any one time there is more CO2 trapped in the plant matter.
To be honest, given the reduction in the Amazon rainforest, just getting back to break even is nigh on impossible. |
|
| |
I tried ordering a rainforest online. |
|

I once tried to get e bay. |

No more coal production, please. Fishd. |
|
| |
Why bury it? Build wood pyramids in the desert instead. |

People won't even know about coal's existence in a few decades. They will have moved on to better fuel soures, such as pure hydrogen. Hopefully, this will come before the fossil fuel companies go totally bankrupt. The people in power want to keep that power for as long as they can, and they're not going to give it up until they can't give us any more fossil fuels, and I hope we're not caught without an alternative when they run out all of a sudden. |

Wood pyramids - great idea - something for the tourists as well then. |
|
| |
[epic], why? Producing a tonne of coal would reverse the environmental impact (at least, the CO2 release) of burning a tonne of coal. In terms of pollution, the process would be carbon neutral. |
|

Pure hydrogen, Kevin? Where do you get this pure hydrogen? |

"Pure hydrogen, Kevin? Where do you get this pure hydrogen?" |

Electrolysis. Sir Harry Kroto (the guy who discovered Bucky Balls) said in a lecture at my university that we're going to have to learn how to use Hydrogen, and I fully agree. I've been recently reading some patents about how to use Hydrogen efficiently, both in production and use. |
|
| |
Yes, I know, but where do you get the energy to make it? Do you use electricity? Do you burn coal to make the electricity? |
|
| |
It doesn't make sense to grow trees purely for the purpose of burying them. On the other hand, using pulp trees to make paper which is then landfilled has pretty much the same effect but with the added ability to get use out of the paper. |
|
| |
The best use is to make expensive furniture. |
|

First, most coal doesn't come from trees. Most comes from the plant matter that fills in bogs which is called peat. Burying and heating it turns it to coal. Second, there isn't really a world shortage of coal. On the topic of hydrogen, Iceland is producing hydrogen using geothermal power. |
|
| |
Bury 'plant-matter' instead of 'trees' then..... |
|
| |
The primary idea wasn't to create coal, which would take millions of years - it was to reduce Carbon Dioxide in the atmosphere.... |
|
| |
If we were to use nuclear power to create the electricity and other forms of electrical generation to create the hydrogen then there would be a none polluting way of putting the CO2 back underground. |
|
| |
Not quite right to say that Nuclear Power is 'non-polluting' - however I take the point that it doesn't generate huge amounts of CO2 like burning fossil fuels does. |
|
| |
I don't think this idea's gonna work..... |
|
| |
Maybe it would be simpler to force all car owners to have a small CO2-hungry plant in their car. |
|
| |
Wouldn't scrub anywhere near as much as the car is producing, but at least it would use up some CO2 - and there's be lots of them. (And it would still work when the car wasn't runnning). |
|
| |
Maybe scrap the tax disk (or whatever is the local equivalent) and replace with a small shrub. (Details could be written on the plant pot). |
