I watched the Hagerty documentary on the Turbine Car the other day, and he said it melted a turbine and the regenerators. It sounds like it overheated for some reason. There's an aerospace company that's taken on the replacement parts, but the regenerators are the hard part. They're very old-school high tech. Apparently, Chrysler ordered all the engineering drawings destroyed, but there are still some Turbine project engineers around who are volunteering some of their time.
