Possible Breakthrough in Energy Storage
Gary Tulie writes: Hi Craig, This could be big. An ultracapacitor made of low-cost non-toxic materials with energy density as good as lithium ion batteries, with many times the charge and discharge rate. Yes, this sounds like it really could …
From 2GreenEnergy Intern Fabio Porcu – An Introduction to Batteries
In my last post, I covered the various types of energy storage. Now it’s time to analyze in detail the possibilities that the batteries offer in this field. We will discuss the various types of batteries, and note the characteristics …

Liquid Ammonia as Fuel – More on the Subject
I figured that my posts on Renewable Energy World on liquid ammonia would eventually get some response. I had been wondered how it could be possible that so few people were working on projects in this area, as it really …
Have a Great Solution in a Huge Market? Consider Making It Too Cheap to Steal
As I’ve noted previously, the eminent venture capitalist Vinod Khosla advises “Since one fails often, address markets that make it worthwhile when one does succeed.” This, of course, is solid advice. But unfortunately, not everyone is a position to swing for the …

Electric Vehicles and Better Place
David Holden writes: I am no adherent of Shai Agassi’s dubious scheme, but it does show the willingness of power companies to support EV. development. As long as think has come up, here are my thoughts on Better Place. 1) …
Electric Vehicles and Issues with Lithium Ion Batteries
Alex C. goes on: In early 1900’s many cars were EVs and then they lost out to gasoline engines due to better cost and performance. 1970’s a large EV wave came in with the fuel crisis that caused gasoline prices …
