Advanced Rail Energy Storage
Can be done. Cost inefficient as hell. Huge energy losses. Highly doubt the Swiss built one. They’re not morons.

Energy Storage
When I first came across the click-bait garbage at left, I was reminded of an earlier post I wrote on the subject of the history of this form of energy storage. Various countries in Europe began using the potential energy …

Gravity-Based Energy Storage
Hardly. Gravity-based energy storage for electricity has been in use since the 1890s. Storing mechanical energy with heavy objects goes back to ancient times.

Pumped Hydro Soon to Go Into Its Second Century
These people claim: An American startup just unlocked hydropower from dry land — with no rivers or dams. In a radical rethinking of water-based energy, an American startup has developed a closed-loop hydropower system that works without a natural river …

Sodium Ion Batteries: Vapor?
Sodium-ion batteries have been around for about 30 years, and there are people who believe that a handful of developers may be close to commercializing this class of technologies. That said, if you have to tell us that your investment …

Is This a Good Clean Energy Investment?
Well, first let’s answer a vitally important question: What is it? What exactly do these people do? To find the answer requires some work; it’s not revealed anywhere close to the top of their website. It turns out, it’s solar …

Energy Storage Investors Should Study This One Carefully
Sodium ion batteries have been under development by the world’s best minds since the mid-1990s, meaning that they’re hardly “unknown tech.” These people (who have no apparent technology value-add whatsoever) just might make you rich, claiming to help investors turn …

Energy Storage
A reader notes: Here is a 10 MB hard disk from the 70’s that I was told cost $40k. Sitting on it is the 1 terabyte hard drive from my laptop. The cost (and size) of data storage is a …

“Gravity Batteries”
Below is a claim about a type of energy storage that exists in great abundance today in the form of pumped hydro. We take off-peak electrical energy and use it to lift a mass against the force of gravity, converting …
