 When you think about electricity, when you think about how much power is used worldwide, you sort of don't think about the fact that a lot of it is wasted getting from the power plants to the house. So I work on making more efficient wires, making wires that actually can transport electricity without losing any of it. It's called a superconductor. Superconductor carries electricity without losing any of it. I'm working on new ways of making them. The major problem is that you have to keep them quite cold, meaning liquid nitrogen temperatures, super freezing cold. I'm trying to solve another problem that there is with superconducting wires, which is that they crack quite easily. They're very brittle. They're made of a ceramic material which is a little bit like pottery. So if you think about trying to make something like clay pottery into a long wire, well, that's just going to break the minute you apply any pressure to it. So what I'm doing is creating a superconductor that's some powder mixed up with a liquid. So the liquid can be spread into any shape. We spread it along the outside of something that already is a wire. So then we have a flexible wire with a superconducting coating on it. I really like the potential of superconductors to be really far-reaching. And at the same time, there's a lot of intricate details which are sort of fun to learn.
