It’s toxic. It's damaging. And long-term painters have suffered from cancer and lung problems. It’s so unsafe you shouldn’t walk into a room right after it’s been painted. But paint is big business and information about it is tightly controlled. In this episode of Leading Ideas, Zoe Piper, Director of ecolour, and her colleagues are offering an alternative: Non-toxic paint for the same price. Host Dr Graham Philips also speaks to Dr Anita Ho-Baille who has developed solar paint that can absorb water and vapour and split it to generate hydrogen and basically run your entire home (eventually). Plus a solar material that can be sprayed onto walls.
