Similarly, I think the article dances around the issues of lifespan and reliability. We know the engines run for somewhere between 20 minutes and a whole racing season without breaking down. They state that a plastic engine was used in IMSA in the 80's, but we're not told if a new engine was used for every race. We're also not told about potential issues with ambient temperature changes. (Plastic tends to become very brittle at cold temperatures.)

For an article that is advocating a radical new technology, it is awful short on facts. I strongly suspect that there are some major issues with this kind of engine that the article completely ignores. I'd also think this would attract manufacturers and racing teams if the technology was so promising.
