My dad had a mate who worked at CSIRO in Australia. It's the Australian government arm in charge of industrial research.

Because of the harsh weather in Australia, they developed house paint that was indestructible. When painted on to the exterior of a building, it would last forever. As in literally forever. This stuff would outlast religion.

They shelved it because no company wants paint that will never need to be refreshed, never needs to touch up for fading, and won't flake off eventually.

No paint company wants to sell just one last can of paint.

That’s the kind of thing the government should be in the business of making.
