Question: If you became big and you had an idea to change the world what would it be.

It would definitely be to use the materials I’m working on to stop global warming, and make lightweight roll-up TVs. What I’m working on is something called plastic electronics, which basically means we make design special materials and make conducting inks. We can control lots of things about these inks, like the colours that they glow if we put electricity for them (great for TV screens and mobile phones) or the colours that they can absorb if we shine light on them. We can use things like your printer at home to print these inks on plastics, but unlike when we print at home our designs can conduct electricity ! This is all really great for light, bendy electronics.

It is also great for the environment. When we use electricity at home it is usually made from things called ‘fossil fuels’. Fossil fuels (coal, oil and natural gas) are pretty bad for the world and are making the temperature go up. That’s pretty bad news for some animals. We can make clean energy though, from things like wind or solar power. Normally, solar panels (devices that turn sunlight into electricity) are made on glass and are super expensive. With our new materials we can print big sheets of solar cells on cheap plastics really quickly- soon we’ll be printing them like they print newspapers. We can print huge sheets and roll them across deserts, or wrap them around our homes or on the roofs of our cars. My friend took our materials to Brazil and they are already on the cars there! That means we can get clean energy all of the time.
