It's a fact that the more advanced humanity gets, the more energy we need. Between 1965 and 2015, the world's energy consumption nearly tripled. Who knows how much energy we'll need in another 50, 100, 1,000 years? Scientists assume it's no different for alien civilizations. There will be a point when the energy resources they can tap from their planet's surface are no longer enough. Never fear — they'll probably have a Dyson sphere.
In a medical emergency, you need a medic who can get on the scene fast, who won't panic, and who has all the right tools and knows how to use them. Or better yet, who is all the right tools. That's right: a team of Russian scientists has come up with a flying drone that doubles as a defibrillator, meaning medical help can take a path that's as short as the crow — or the robot — flies.
Imagine a future ruled by robots. Across this mech-dominated landscape stalks one particularly capable bot. Its six precise arms bear it inexorably forward as its three eyes whir and scan the horizon for its prey. Finally, it finds what it's looking for. Deftly stepping over any obstacles in the way, the spider-like thing clambers until its quarry is in its clutches — then it comes scurrying back with a chocolate bar for its human master. Meet HEXA, the spider-bot that does whatever you ask, and looks as creepy as possible while doing it.
One quick and easy way to induce anxiety is to misplace your phone charger. You're stressed out just thinking about it right now, we know. What if instead of dealing with your wiry bundles and ports and mats and plugs and cords, you could just...walk into a room? That's basically how Wi-Charge works.
One of the sad truths about materials is that if they're strong, they're also probably heavy and cumbersome; if they're lightweight, they're also probably weak and breakable. That's what makes Braeön so cool: a single ribbon of the stuff can pull 2,000 pounds (900 kg), but an entire roll weighs less than a football.
