An easier-to-build solar cell
Solar cells are not easy to build, but a new technology from Notre Dame could, someday, change that. It involves a nanoparticle paste made from t-butanol, water, cadmium sulfide and titanium dioxide. Here, you watch the process of constructing a solar cell this way and see why it could be easier and cheaper than current options. The downside: [...]
Flip-flops with a secret compartment
These flip-flops have got an arch-support with a hidden pocket where you can leave your keys and wallet while you're in the water. I have no idea whether the rubber is stiff enough to make walking on your car keys comfortable, though. ArchPort Flip Flops with Hidden Storage
The Flip is dead
As has been widely reported, in a cost-cutting move Cisco has determined to set its Flip pocket-camcorder division adrift. No, correct that, much as it pains me to say so, “set adrift” implies that there’s some possibility that—despite low rations, little water, and floating some 2,000 miles from the nearest land mass—a Divine [...]

Tsunami vs Japanese Harbor
This eyewitness video of the March 11 tsunami striking Japan shows how, in under 10 minutes, a harbor in Oirase Town, Aomori Prefecture goes from business as usual to, well, gone. While other videos have shown massive destruction or endless floods, this one shows a huge dry area that completely fills with water, making it easy to see just how [...]
Blood Falls in Antarctica
There is a five-story, blood-red waterfall pouring slowly from the Taylor Glacier in Antarctica's McMurdo Dry Valley. Its back story, at Atlas Obscura, is simply remarkable... Roughly 2 million years ago, the Taylor Glacier sealed beneath it a small body of water which contained an ancient community of microbes. Trapped below a thick layer of [...]
What We Talk about When We Talk about Bandwidth
Cellular carriers' competing claims as to what constitutes 4G (fourth-generation) cellular data networks got me to thinking about how speed is only one part of the story about why allegedly faster networks are being built. I've been writing about Wi-Fi since 2000, and that informs my thinking, because Wi-Fi has matured to a point where raw [...]
