I do not subscribe to conspiracy theories and fantastic gossip. It just does not go with me. I trust science. Every day of my life. If the Taiwanese team did something of the sort you are saying I would like to know about it. Did they create a functioning marketable aluminium air batter? Or perhaps they have created a safe opto-electric nuclear battery? If they have, where are they? In fantastical folklore of Taiwan or they actually exist?
Here are some advice in the video below, on how things should really be done. Even the biggest consortium started small some day. Specially listen to the one at 05:09
Natural gas is actually much cleaner than oil or coal. In fact natural gas is considered a fuel just between renewable and fossils since it has the lowest carbon to hydrogen ration out there among the fossil fuels. As for the rest, there is a renewed interest in nuclear technology since this is the only type of energy which can sustain humans for millions of years at an increasing rate of consumption. With upcoming 4th generation reactors, SMR technology and the fast breeders or in future with travelling wave reactors or possibly fusion reactors, fossil fuels will not be able to compete.
