Ability to store electricity efficiently

Interesting innovation, cannot comment or compare with other storage systems available. But if humans can innovate a safe and efficient way to store electricity then it has many interesting application
1. Full potential of solar electricity for that matter any renewable energy can be fully achieved
2. City planners can work out energy efficient light systems. That can help country like India which wants to increase penetration of availability of (reliable) electricity
3. Has interesting application in hybrid cars/trains it can save a lot of energy

Interesting to see how this space of storing electricity efficiently is evolving.

Economics to layman

I have always been fasinated by economics but got bogged by the way it is communicated to layman like me. But this site is amazing in presenting such complex information/data in an easy to understand visual form.

I can now understand why they say "A picture is worth a thousand words"
