Tuesday Tip

For our year end special we have not one but two tips. The Copenhagen conference doesn't seem to have been much of a success but we have two major tips for governments of the world to use or loose.
From Rowlyone, the love of my life
As you know, when you put a heavy object into water the mass of the object displaces water, making the water level rise. So, it stands to reason that if all the boats, yachts, ships, schooners, container vessels etc were removed from the sea, the sea level would of course drop.
But there's more
My theory is that someone should invent a paint that changes from black to white according to light and temperature. Every roof in the world would be painted with this special paint. In the winter the paint would be black, absorbing heat and retaining it. In the summer the roofs would be white, reflecting the heat away from the earth, thus reducing global warming while allowing the houses to remain cool.
Go well and prosper
