I say every MTR station should install a couple of these, I wonder if this thing would help in crowded HK

I wonder how much particles are generated powering that thing.
Depends on the power source right... This is why clean energy generation, at source, is important
For instance, as much as I love Tesla and what they represent, in certain countries, *cough* Australia *Cough* for example, they are not all that clean since their power comes from dirty old fossils.
The sooner the world moves to clean(er) energies, the better - at least HK gets some of it's energy from the atom.
My point was the rate of change . A few years ago it was nearly 100pwrcent . To go from that to 100 percentage renewable in some hours (or hour or minute )is remarkable . And not actually good for the system .
Seriously? You are comparing a reactor destroyed by a tsunami to the intermittency of a wind farm or a solar panel?
Nuclear is an excellent baseload option for zero carbon emissions. However it's also expensive. But the majority of the costs of nuclear comes from the safety - safety on top of safety on top of safety. Fukushima was one of the world oldest reactors and didn't have quite as many layers of safety as modern ones. And it still didn't kill anyone.
