Steam

Prostate cancer is usually treated with surgery and radiation therapy, but these can have drastic side effects. A new clinical trial is exploring the safety and efficacy of killing the cancer cells with a blast of steam.

A team of researchers at the University of Central Florida have developed a prototype steam-powered space probe using water as a propellant. The World Is Not Enough spacecraft can operate indefinitely by topping off on ice gathered while visiting asteroids and other bodies to fuel future travels.

Working at MIT’s Department of Mechanical Engineering, scientists claim to have created a sponge-like graphite-carbon material that helps convert water to steam using sunlight only one-hundredth as bright as that required by conventional steam-producing solar generators.

The CSIRO has claimed a world record for the highest temperatures ever recorded using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. This achievement is touted as a breakthrough for solar energy production.
