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.   612 more words

Energy Storage

Colours + Compounds = Colourful Compounds

Isn’t it interesting to find out that some compounds are in variable colours (which are really pretty) while others are colourless (you can just see straight through the compound)? 468 more words


Analysis of Metallic Oxides
