NYTimes.com: Building a Bridge of (and to) the Future
By HENRY FOUNTAIN
Carbon- and glass-fiber fabric tubes filled with concrete offer strength, light weight and resistance to corrosion.
"Long the stuff of surfboards and pleasure boats, and more recently used in aircraft wings and other components, plastic polymers reinforced with fibers were first researched for use in bridges in the 1980s. Civil engineers were attracted to them for the same reasons other designers were — their strength, light weight and corrosion resistance."

Rockets Able To Run On Toffee
For real!
The UK's The Scotsman (10/7) reports, "Rockets can run on toffee, a scientist has proved. Jem Stansfield demonstrated a hybrid rocket powered by the sweet on BBC1's Bang Goes The Theory." Ray Wilkinson of the University of Hertfordshire "suggested the experiment could help scientists find environmentally-friendly materials to fuel rockets."
The rocket was capable of powering a bicycle ridden by Mr Stansfield at Buckinghamshire Railway Centre. Hybrid rockets require nothing more than a cheap solid that burns and a gas – in this case nitrous oxide – to provide oxygen, he said. Ray Wilkinson, principal lecturer in aerospace design and rocket propulsion at the University of Hertfordshire, suggested the experiment could help scientists find environmentally-friendly materials to fuel rockets.
