Physicist: There Was No Fukushima Nuclear Disaster

The terrible toll from Japan's tsunami came from the wave, not radiation

I have watched a TV programme called ‘Fear Factor.’ In the series there are contestants who have to confront their worst fears to see who bails out and who can fight the fear and get through.

People who are afraid of heights are made to Bungee-jump off a high bridge, and people who are scared of spiders or insects are made to get in a bath full of spiders.

In virtually all cases the contestants later say that the fearful experience was not actually as bad as they feared. So the fear of the fear was greater than the fear itself ‘when the chips were down.’

This is often the case in life, that the fear of some factor turns out to be worse than the experience itself. The human mind builds a very scary image in the imagination. The imagination then feeds the fear.

If the picture in the imagination is not very specific or clear it is worse, because the fear factor feeds on the unknown.

This is what has happened in the public mind concerning nuclear power over the last half century. Concepts concerning nuclear reactions and nuclear radiation are in themselves complicated and mysterious.

Over the last couple of decades physics advances in fields such as quantum mechanics, which is linked to nuclear processes has compounded matters for the public. The image of strong and mysterious forces and effects is now well entrenched. There are Hollywood movies and TV programmes about space travellers or alien invaders who use time travel and quantum forces, and then battle to evade the dangerous intergalactic nuclear zones.

Lawrence Solomon: Fossil Fuels Now Beat Wind And Solar On Environmental As Well As Economic Grounds

Wind and solar power – the darlings of environmentalists and multinationals alike – meet but a picayune proportion of the world’s energy needs and even then they need a crutch – generally in the form of fossil fuel backup – to sustain them. Because the Sun doesn’t always shine and the wind doesn’t always blow, society would be vulnerable – unsustainable – if these renewable technologies tried to meet human needs on their own.

The environment would be vulnerable, too. When governments and industry try to impose renewable technologies on us on a large scale, they lay waste to nature. Industrial wind farms have become major killers of birds, from the majestic bald eagle to tiny songbirds. Last year, according to the United States Geological Survey, wind turbines killed some 900,000 bats, in the process harming farmers who depend on bats for pest control – the USGS pegs the value of bats to the agricultural industry at $23-billion annually.

Wind’s ecological trail of destruction extends back to China, which supplies most of the rare earths required in the construction of wind turbines. When we in the West erect a wind turbine, reported an investigative article in the UK’s Daily Mail, we help create “a vast man-made lake of poison in northern China” that, according to locals, withers their crops and kills their animals.
