hasek, That's not a good idea, it costs too much and quite a risk involved. Coal is not an ideal fuel for industries, and many people against using it. Many power plants already converted to natural gas, future vehicles too, more natural gas will be used. Company should concentrate on developing properties & techniques on producing rare earth elements. Right now China controls almost all REE productions worldwide, and the prices are sky high. Industries need those minerals, and have no choice but to pay for such high prices. It will take time but worth it years & decades down the road.
