Five Technologies That Could Change Everything
It’s a tall order: Over the next few decades, the world will need to wean itself from dependence on fossil fuels and drastically reduce greenhouse gases. Current technology will take us only so far; major breakthroughs are required.
What might those breakthroughs be? Here’s a look at five technologies that, if successful, could radically change the world energy picture.
They present enormous opportunities. The ability to tap power from space, for instance, could jump-start whole new industries. Technology that can trap and store carbon dioxide from coal-fired plants would rejuvenate older ones.
Success isn’t assured, of course. The technologies present difficult engineering challenges, and some require big scientific leaps in lab-created materials or genetically modified plants. And innovations have to be delivered at a cost that doesn’t make energy much more expensive. If all of that can be done, any one of these technologies could be a game-changer.
