Solar panels are a double-edged sword. On one hand, they’re a great way to get clean electricity. Unlike fossil fuels, sun power isn’t radically altering our climate, and we won’t be staring down the barrel of a “peak sun” problem for at least another 5 billion years. On the other hand, they are relatively expensive … Continue reading

Cheap, Clean Power for the Rural Poor
Which location do you think is better prepared for the transition to clean energy: the wealthy, green-minded city of San Francisco, or the poor, rural villages of East Africa? If you picked the African villages, believe it or not, you’re on to something. An incredibly innovative startup called Off.grid:Electric has spent two years working to … Continue reading
Grabbing Free Energy from Train Tracks
It’s not exactly breaking news that freight trains produce enormous vibrations. But until now, it’s never occurred to me that it might be possible to capture that vibrational energy and convert it to electricity. From NBC News’ FutureTech, engineering professor Lei Zuo has invented a device to do just that. It attaches to the tracks … Continue reading
Radical Ways to Fight Extinction
Look, here’s a picture of a tiger: A century ago there were about 100,000 of these guys in the wild. Today, that number has dropped more than 95%, meaning tigers might soon be gone forever! And there are thousands of other species in peril too (some estimates range as high as 30% of all species on … Continue reading
Advances in Sea-Powered Energy
From Fast Company’s Co.Exist series, check out 8 of the latest advances in ocean-powered generators. Most of the devices are being developed in Scotland, which is apparently a world leader in marine energy investment – who knew? They’re all well beyond the design stage, with working prototypes being deployed and tested in the rough waters … Continue reading
Bicycles Are the Future of Transportation
This may come as a surprise, but the future of transportation has been around for two centuries already. Of course, back when ol’ Baron Karl first put two wheels together and rode them around 1817 Mannheim, he just thought he’d made a kind of a re-usable horse. He certainly had no idea his invention would … Continue reading
My Interview for iCoolhunt
iCoolhunt is a social, location-based game that encourages people to seek out blossoming trends around them. These “coolhunters” can then capture, share, analyze and discuss their discoveries on the website. It’s certainly a novel way to think about the future. I especially like the way it creates a community focused on discovering – or even … Continue reading
10 Ways for the World to End
There’s something fun about pondering the end of the world, as many movie fans can attest. The end of a single life might well be a tragedy, but the end of all human civilization is so epic that it’s hard not to be awed. And unless you think humans will be around forever (which I’m … Continue reading
The Algae Revolution
It may look like pond scum to you, but one day, the plant-like organism known as algae could rule the world. How can such an immobile, simple-bodied eukaryote pull this off? For one, many of these little guys are photosynthetic. “Big deal,” you say. “Every plant on earth can claim the same thing, from the … Continue reading
Hacking Civilization
What’s the future of human civilization? Cosmic Revolutions has looked at a lot of big questions, but this one’s as big as they come. Indeed, everything I’ve posted so far has tried to fill in a piece of the answer. But today, I want to step back, way back, and try to catch a glimpse … Continue reading
