Powering Society With Poop and Pee
Have you ever had your power knocked out by a storm? If so, you know that with no electricity, your lifestyle regresses about 100 years into the past.

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 »

A longer lifespan, plus reduced risk of Alzheimer‘s and cancer, is all the justification I need. No, I’m talking about … Continue reading »
Peak Oil: Disaster or Salvation?
Oil is a finite and non-renewable resource. This is not a political position, nor a scientific theory, but a straightforward fact. “Peak Oil” is the time at which worldwide extraction begins to slow. Wells won’t run dry overnight, but beyond peak oil, dwindling supply will make oil ever more difficult and expensive to produce. The … Continue reading »
Welcome to the Urban Planet
In the last couple of years, our planet’s human inhabitants have crossed two major thresholds, one of which indicates major problems ahead, and the other of which offers a glimmer of hope. We’ll get back to the hopeful bit in a minute, but let’s begin with the problem, which you’ve probably seen in the news … Continue reading »
Solar Power, meet Microfinance
Since my day job is at a non-profit with tight budgets, it’s not often it introduces me to new technology. But thanks to a mid-October workshop hosted by our international department, I had the chance to get hands-on experience with a remarkable innovation: it’s a deceptively simple device, yet it has the potential to lift … Continue reading »
