Bill Gates invests in the future of electricity storage – Liquid Metal Batteries

Liquid Metal Battery Corporation, an MIT spin out that’s developing new technologies for electricity storage, has raised $15 million in funding from Khosla Ventures, Total and Microsoft co-founder Bill Gates. The technology behind the company was developed by Dr. Donald Sadoway (his famous TED Talk), a professor at the Massachusetts Institute of Technology who was recently named one of Time Magazine’s 100 Most Influential People in the World.

“Large-scale electricity storage will be a critical part of reinventing the global electric grid infrastructure, and LMBC has developed the most innovative chemically-based solution that we’ve seen,” said Andrew Chung of Khosla Ventures.

Bill believes that creating large-scale batteries to store energy is a critical problem to solve if solar and wind energy are to become mainstream. In this video, Bill and MIT Professor Donald Sadoway discuss the importance of new battery storage technology and Sadoway’s focus on the development of a “liquid metal” battery.

To get more technical, the liquid in the all-liquid battery is molten salt and liquid metal, which:

“…avoids cycle-to-cycle capacity fade because the liquid electrodes are reconstituted with each charge – similar systems have operated in a lab environment for more than 17 months with daily cycling and no reduction in performance. The molten salt electrolyte combines high conductivity with abuse tolerance at low cost. Self-segregation due to three immiscible liquid phases of different densities (e.g. oil and water separation) allows for robust operation and ease of manufacture. Together, these attributes will enable the liquid metal battery to exceed 70% round-trip AC efficiency for over a decade without degradation.”

Photos from inside Apple Headquarters

It’s the Chocolate Factory for tech nerds.

Search the web for “Apple HQ,” and most of the results you get will be pictures of Apple’s Cupertino headquarters — from the outside. Usually with some fanboy standing next to the “1 Infinite Loop” sign. But what we really want to see is what’s inside the ultra-top-secret place where all our favorite gizmos are dreamed up.

This discussion will be moot a few years down the road when Apple opens its gigantic new wheel-shaped campus. But for now, this is the ultimate Nerdvana.
