Revisiting Jay Whitacre's Innovation Story

Earlier today energy storage startup Aquion Energy announced that the cost of its breakthrough saltwater battery technology should fall by 50% in as little as 2-4 years, instead of the 10 they originally predicted. That's an incredibly confident statement to make for a company in one of the world's most…

How to calculate salt activity

My work in membrane processes for desalination and blue energy often requires me to calculate the thermodynamic properties of salts. The tricky part of this is determining something called the activity of the salt. As long as I know the salt concentration, I just need to find the activity coefficient…

How to add MathJax to a Ghost blog

I recently migrated this site to Ghost, and since some of what I write about is technical, I wanted to have the ability to enter LaTex-style mathematical equations and have them display nicely. Mathjax is an excellent cross-browser solution, and it turned out to be easy to add to Ghost.…

The untapped source of clean energy you’ve never heard of

Blue Energy makes electricity from saltwater Emerging “blue energy” technologies are on the verge of unlocking a new way to generate electricity from water. Blue energy systems extract energy from a difference in salt content between two kinds of water. Where rivers flow into the sea, for example, fresh river…
