UK engineer Mayflower has developed a new engine which could reduce fuel consumption by 40% and noxious emissions by half. Based on the combustion engine, the 'e3' design adds a pivoted lever arm between the crankshaft and piston, enabling the 'big end's' motion to be changed from circular to elliptical.

Mayflower claims this means more fuel can be burned, generating more power and fewer emissions.

The city of New York is urging patriotic American citizens to subscribe to a £670M bond that will provide funds to help clear up the World Trade Center site.

The 'recovery notes', backed by tax receipts, are tax exempt and offer a yield of 2.1%. They are being marketed by investment bank Bear Stearns.
