The Energy Observer is a boat that makes its fuel out of seawater

The Energy Observer is a boat that makes its fuel out of seawater

"We test and mix a number of different [energy-generation] technologies, but the secret is in the mix," explained project manager Louis Noël Vivies. The vessel is covered in 168 square meters of solar panels, both laminated onto the shell and in rigid racks over the hull. The latter are double-sided, too, to pick up light…
Renewable energy can generate billions of dollars in health benefits

Renewable energy can generate billions of dollars in health benefits

Ten states across the Midwest and Great Lakes region of the US could see $4.7 billion in health benefits in 2030 if they stick with current renewable energy standards, according to a new study from MIT. That’s about a 34 percent return on the $3.5 billion price tag associated with actually building out that infrastructure…
Energy Vault raises $110 million from SoftBank Vision Fund as energy storage grabs headlines

Energy Vault raises $110 million from SoftBank Vision Fund as energy storage grabs headlines

Imagine a moving tower made of huge cement bricks weighing 35 metric tons. The movement of these massive blocks is powered by wind or solar power plants and is a way to store the energy those plants generate. Software controls the movement of the blocks automatically, responding to changes in power availability across an electric…

Estimate the Energy of an Utterly Massive Wind Turbine

It's amazing that we can get electrical power just from the wind, but that's exactly what happens with a wind farm. It's a collection of wind turbines in a particular location with abundant wind. And as with many things, bigger is better. The Hornsea Wind Farm, for example, is being built 75 miles off the…
