Take a Cool Guess—The Fun Quiz on Renewable Energy and Environmental Sustainability. Today’s Topic: What Happens Upstairs
Question: The aircraft we come in contact with on a day-to-day basis flies in the troposphere, i.e., under about 50,000 feet. Are there aircraft that function in the layer above that, i.e., the stratosphere? If so, how are they powered and …
Concept in Energy Storage Features New Idea, Old Technology
Here’s a novel concept in energy storage: a wind turbine integrated with its own mass that can be moved against gravity to generate and store potential energy which is then converted via a generator to electricity when required. It’s akin …

Energy Storage Making Progress
As a colleague of mine likes to say, “Even sushi has a better storage model than energy.”
How Feasible Is This Energy Storage Device?
Here’s a question for you mechanical engineering types out there: Can you please comment on this energy storage device? I saw this at a conference a few years ago, but forgot about it until just now.
Intro To Renewables
Here’s a video designed for newcomers, an introduction to the subject of energy storage, making the point that batteries are making progress via new technology.
Integrating Wind and Energy Storage
As noted here, the huge Chinese wind turbine concern Envision Group is buying Nissan Motor Company’s battery manufacturing business.
ABB on Energy Storage
The industrial giant ABB was a client of mine in the late 1990s. I have a distinct fondness for them, though they represent the only business trip I regret not being able to make; due to a conflict in my …
Energy Storage
Those looking for a primer on energy storage will enjoy this piece in the New York Times, complete with wonderful animation. For some reason, they failed to include flywheels, which is ironic because I happen to be taking on a …
Concept in Energy Storage
A fellow in Sudan wrote to ask me about energy storage by compressing a large spring, pointing out, quite correctly, that the force associated with compressing a spring is a function of the distance over which the force is applied, …
