Why we must go back to the Moon

Economic growth is being constrained by resource scarcity.  The environmental cost of ripping minerals out of the ground is also probably becoming too high a price to pay.  In addition to this, the vast amounts of energy needed for mining, extraction and refining of minerals makes a significant contribution to the carbon added to the atmosphere.
It is likely that the Moon contains an abundance of valuable minerals, including rare earths, It also has a vast amount of totally predictable solar energy, There is therefore a pressing economic imperative to go back to the Moon, and soon.  The minerals required for our economic well being could be mined and refined on the Moon using solar energy.  It is likely that there is sufficient water for the manufacture of rocket fuel which would be needed to send the refined product back to the Earth. 
All of this would be done with very little environmental impact on the Earth.

You do see some funny things in St Ives.  I knew times were hard at the BBC but really....

Nuclear Energy

Royal Society of Chemistry  organised a great public debate at the Royal Society of Chemistry's Chemistry cetnre, which took place on Thursday 7 July.

The pros and cons of nuclear energy were discussed by an expert panel of people consisting of two pro nuclear (George Monbiot and Malcolm Grimston) and two anti (Doug Par and Roger Levett).

The debate  can be watched on the link.

The motion in favour of nuclear energy was carried by 63 votes to 9.  A conclusive result favour of this environmentally benign source of electricity.
