Accidental nuclear war - NOT amateur radio

Although totally unaware at the time, the world was on the brink of nuclear war in 1983. The USSR detected incoming missiles (actually a false alarm) and only the actions of one man prevented a retaliation.

You wonder how the world would manage today with people like Trump and Putin at the helm. A nuclear war by accident is more likely than by plan.

Failed missile test - NOT amateur radio

So, the North Korean missile test failed. I am not that surprised as I feel the USA had something to do with this. Of course, I may be totally wrong, and indeed I hope I am.

The Trump administration would be unable "neutralise" the North Korean nuclear threat without unpredictable consequences, but the USA Secret Service was probably in a position to do something to put a "spanner in the works".  Of course, the USA never uses such underhand techniques.

Nuclear Fusion - NOT amateur radio

There is lots of research going on into nuclear fusion.

Unlike nuclear fission which is used today and results in long-term nuclear waste, nuclear fusion could use the almost endless supplies of non-polluting deuterium in seawater. It is probably decades away from being commercially possible as the technical challenges are immense. Research is starting to yield results though.

Nuclear fusion holds the potential for almost endless, low cost, energy. It could hold the keys to the future, but it is not yet possible, although the research must continue. This is one area where worldwide collaboration would benefit us all.

As for electric cars, although a "good idea" I think range is a real killer. Most journeys are short, I know, but ranges of several hundred miles on a charge are really needed and I just can't see this even with the best battery technology likely in the next few decades. Replacement batteries for electric cards are very expensive. No, this is an area where a lot more research is needed both in transport for the masses in an age beyond carbon and in battery technology. We need some "thinking outside the box" in these areas. Cars that do not need diesel or petrol are essential. We have to crack this one and come up with good solutions.

Cynical, me? - NOT amateur radio

OK, I know I am becoming a grumpy old man but I was not impressed by the latest statements that the exchange of nuclear waste with the USA would benefit cancer sufferers. To me, this sounds like "spin" which we can well do without. We are NOT stupid.

China and our nuclear power - NOT amateur radio

So the UK government is to "guarantee" China's £2 billion investment in a new nuclear reactor at Hinkley Point in Somerset. So, we are happy for China to be involved, have access to all our nuclear details? We must be desperate! Investing in better insulation, clean renewables etc. would render this totally unnecessary.

And what about the spent fuels that need safe storage for a very very long time?

Nuclear submarines + UK Trident nuclear deterrent

There's a programme on BBC TV tomorrow about the design and building of the UK's latest nuclear submarine. The preview said that each costs 1 billion UK pounds to build!! Couple this with the 100 billion pounds we are likely to spend on upgrading Trident nuclear weapons and we are talking about a huge amount of money.  I find these sums on such weaponry obscene and plain wrong. If similar amounts were invested in the search for sustainable energy sources I'd be much happier.

Nuclear Fusion breakthrough?

Some recent research may have helped the dream of unlimited and pollution-free energy from nuclear fusion become a big step closer. Scientists in the USA have demonstrated that containment of atoms for fusion using laser beams is far less problematic than first thought. Unlike current nuclear fission, nuclear fusion reactions create no radioactive waste materials. Potentially nuclear fusion reactors, if created on a commercial scale, could dramatically help supply clean energy the world so badly needs. See http://news.bbc.co.uk/1/hi/sci/tech/8485669.stm
