Robots can do a lot for us: they can explore space or they can cut our toenails. But do advances in robotics and artificial intelligence hold hidden threats? Three leaders in their fields answer questions about our relationships with robots.
A whole range of alternative technologies will be needed to fill our huge appetite for energy and reduce our dependency on finite resources. Echo Ouyang, a PhD student in the Department of Engineering, is making an important contribution to research into the development of geothermal energy technology which might one day heat (and cool) our homes.
