There have been thorium reactors (one molten salt, and several
others, e.g. ball pile) in operation. All of them have been strictly
experimental, and none of them a resounding success. Molten salt
cores have interesting advantages, in theory. In practice, when
rolling out reactors you build certified, commercial products.
If one would want to start developing a molten salt thorium
reactor, it would take somewhere in 15-20 year time scale to
roll out first ones, and about as much (assuming the project
is a success) to make a difference. We cannot wait half a

To be able to streamline requires a working process.

This is not at all obvious, and we're talking about electricity
half a century from now. A little bird tells me thin-film PV
will blow away everything.

The last (nonrenewable Fischer-Tropsch) synfuel plants were
shut down in early 1980s. What we need is developing a mild
CO2+H2 (electro)synthesis process and scaling it up to gigaton
Given that nobody is even working on it our chances to switch
over to renewable gases and liquids are not good.

It does of course make above far more difficult. As do
other negative factors.
Notice that the voters are completely oblivious to this
extremely basic issues, so of course their representatives
(about as much oblivous and/or ignorant) see no need to
address them proactively. The result is quite predictable.
