From tattoo batteries to paint that powers a car, from floating solar farms to wires made from DNA, catch up on the year's most exciting energy news.
While fossil fuel energy represents the most common class of power generation, solar power just made a big leap forward, hitting 46 percent efficiency. Trace runs down the details and sees how the breakthrough stacks up against other power systems.
Nuclear power delivers about 19 percent of energy in the United States, and while it has many pluses, its waste and potential meltdown issues still make some people nervous. Julian explains how molten salt reactors might be the best nuclear option.
Two MIT engineers have designed a better reactor, one that deals with the industry's biggest problems: waste and safety.
Tech does double duty this week, as we look at floating gardens that clean rivers, houses that produce oxygen and drones that create a Wi-Fi network.
Built like oil rigs, offshore reactors would be safe from earthquakes, too. Continue reading →
You may have seen that image purportedly showing the alarming spread of Fukushima radiation across the Pacific. But dig deeper and you'll find that's not the case at all. And that's not the only piece of false information about this nuclear disaster.
According to some scientists, we must begin using more nuclear power to keep global warming from accelerating. But that creates a huge nuclear waste problem. A University of Sheffield team thinks it might have found a unique way of handling it.
