A tensile strength of 150 GPa for a CNT wire? Currently, the record stands at 52 GPa, in line with theoretical predictions from the strength of the carbon-carbon bond. I'm quite afraid that the challenge is a dud, simply because they are asking for a material that is made of atoms, but held together more tightly than atoms can hold on to each other. If a clever bloke manages to solve that little problem, he deserves more than a measly $50,000, he deserves the Nobel prize weighing in at over $1,000,000!
