Scientists losing the Climate Change Plot

You would have thought that the scientists who work on climate change science would be only too pleased to share the data they gather, upon which they base their climate change calculations. After all every scientific theory needs tested and retested and tested again by as many different qualified people as possible. It is only by such a process of peer review that the science gains credibility and with credibility comes public acceptance. Climate change certainly needs to be studied by as many people as possible because it is important that the public accepts the theory. Continue reading

The Decline of Western Civilisation

Our Western culture – the civilisation of Europe and the USA and Canada has dominated the world for many centuries. It has been the most affluent and successful society in these times.

Is our Western society going to remain dominant or will the cultures and civilisations of China, Arabia and India overtake us and dominate us? Is our culture in decline or are other cultures simply developing to compete with ours? Continue reading

The Renewable Heat Incentive Premium Payment Scheme

On Monday 1st August a new UK government incentive is available for up to 25,000 homes for householders who opt to install a renewable heating system. A householder can get a grant of as much as £1,250 towards the installation costs of solar heating panels, air and ground source heat pumps and biomass boilers. Those who are not on the gas grid network will get precedence as they will almost inevitably be heating their homes and their water using electricity or heating oil, instead of natural gas, which is the cheapest and most environmentally friendly of all the fossil fuels.

Frost Damage in Heat Pipes

German manufactured products are famous for being rigorously tested. One of the leading test institutes is TUV Rheinland which has a special expertise in testing thermal solar evacuated tubes. Evacuated tube solar collectors were originally designed by Dornier in Germany. There are various kinds of evacuated tubes but one popular and expensive kind is the tube which contains a heat pipe – a sealed pipe which usually contains a fluid which expands and contracts according to the heat and delivers heat through a manifold through which a freeze resistant glycol is passed as a heat exchange medium.

We’re Having a Heat Wave

For nearly a week the mid-east of the United States and Canada has been experiencing record breaking heat. Newark, Washington DC. Baltimore, Portland, Concord, Providence have all had record temperatures at or very close to 42C. In fact some 220 individual heat records for July have been broken.

In most places the humidity has been high, so it feels even hotter than the temperature records. Continue reading
