Could 'Fire Paste' Replace Shuttle Tiles?

pipingguy writes "Troy Hurtubise, of bear suit fame, claims to have invented a physics-defying substance called fire paste. "I could coat the belly of the NASA space shuttle with fire paste for $25,000 (US), instead of the $60 million it costs for them to put tiles on it," Hurtubise said. "It can stand up to the heat of re-entry to the earth's atmosphere, and then they can simply wash it off.""
