Extracting Power from Seawater without Nuclear Fusion

Every once in a while, I find it refreshing and stimulating to stop thinking about circuits and to ponder where we will get all of the electricity to power those circuits in the coming years. During a recent trip to the big island in Hawaii, I got a reminder. My wife and I visited NELHA, the Natural Energy Laboratory of Hawaii Authority, located between the ocean … Read More → "Extracting Power from Seawater without Nuclear Fusion"

Tons of LEDs – One at a Time

It just seemed so wasteful to him! All he needed was a thin coating of flour on the chicken, but the only way to do that was to dredge the piece in a pile of flour. Like, about 100 times more flour than he really needed. He could reuse the flour for any other pieces, but, once you were done for the night, he’d be throwing away more … Read More → "Tons of LEDs – One at a Time"

AI Meets AC/DC

“For those about to rock, we salute you.” – Brian Johnson

Let’s play a game! First, we’ll divide the players into two teams. The first team includes fluffy kittens, nuns and orphans, baby ducks, and Delta blues guitarists. The second team includes patent trolls, the Ebola virus, personal-liability lawyers, and Brussels sprouts.

Which team does … Read More → "AI Meets AC/DC"

Full-Power WiFi at Half the Power

In IoTland, communication is king. It puts the Internet in the IoT. But how to communicate? LTE? BlueTooth? WiFi? It partly depends on the application and the location, but it also depends on how far you are from a wall plug.

Because many IoT devices are small, portable, and – this is key – battery-powered, they will forever be infinitely far away from the wall plug. While WiFi has … Read More → "Full-Power WiFi at Half the Power"

It’s Getting Hot in Here

We know that energy is all around us, but how exactly do we harness it? To start things off this week, we take a closer look at an interesting new energy harvesting technology developed at MIT called a “thermal resonator.” By utilizing the gradual ambient temperature changes that occur over the course of a day, this technology can literally pull electricity out of the … Read More → "It’s Getting Hot in Here"
