Sia has come up with a really good incentive structure to ensure that hosts don't pull the plug. When a host and renter create a storage contract, both pay in. If a host goes offline then she loses her collateral.
Have you ever hired someone who was great in the interview and on paper but didn't work out? Any idea why?
I think a great, brief handbook could go a long way.
One of the main hurdles is that we have poured money into our modern-day reactors, and have constructed hundreds of plants. If we were to switch to thorium, we would have to essentially start from scratch - new research, new plant designs, new training, etc. It is very difficult to justify a complete switch from uranium, as it would be incredibly costly.
In other countries, however, thorium reactors could be very beneficial. Countries using thorium would not be able to produce nuclear weapons, which would give the world great peace of mind. This could minimize risks in unstable countries - we wouldn't worry if Iran was building a thorium reactor, for example.
There are also other types of reactor designs that use nuclear waste to create power. I believe our nuclear future lies with these types of reactors, rather than with uranium or thorium.
