Chris Connors of MAKE has a post about "a new way of generating electricity with the slow moving currents found in most of the rivers and oceans of the world." (Video here.)
VIVACE is the first known device that could harness energy from most of the water currents around the globe because it works in flows moving slower than 2 knots (about 2 miles per hour.) Most of the Earth's currents are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently.
VIVACE stands for Vortex Induced Vibrations for Aquatic Clean Energy. It doesn't depend on waves, tides, turbines or dams. It's a unique hydrokinetic energy system that relies on "vortex induced vibrations."
Ocean currents can power the world, say scientists

Marginalized Native American communities throughout the United States could have better access to high-speed internet if the Federal Communications Commission (FCC) decides to allow tribes to use the Educational Broadband Services (EBS) spectrum for services like telemedicine, transmitting medical records electronically, or an online high school.
U.S. Federal Communications Commission Chairman Ajit Pai proposed a new rule to allow carriers to block robocalls. “The American people are fed up with illegal robocalls,” he said.

Kudos to those of us who have chosen a less wasteful third option to “paper or plastic” at the supermarket or club stores. Tote bags are reusable, but they can be a pain to tote around. Here’s an upgrade to that planet-saving measure. The Club Cart Lotus Trolley Bag is that rare tote you’ll want […]
