USGS reports: “The government-run “Cash for Clunkers” did much more than just stimulate the economy and raise awareness of carbon emissions. It also caused demand for a little known and little used mineral compound called sodium silicate. The program required that buyers of clunkers immediately kill the engine of the car — a task most efficiently done by running the engine with sodium silicate. When a vehicle runs for a few minutes with this compound in place of engine oil, the engine seizes, and it cannot be reused.”
