German scientists have constructed a powerful new light system that can focus energy equivalent to the radiation of 10,000 suns onto a single spot. Eventually, they hope, this "artificial sun" could be used to produce environmentally-friendly fuels.
A 220m-tall wind turbine featuring 35 tonne blades has just set a new world record, producing a whopping 216,000 kWh of energy over a span of 24 hours. That's enough to power an average American household for 20 years.
Typhoons are generally associated with mass destruction, but a Japanese engineer has developed a wind turbine that can harness the tremendous power of these storms and turn it into useful energy. If he's right, a single typhoon could power Japan for 50 years.
