A new generation of batteries as the missing link to robust renewable energy

Donald Sadoway, a professor at MIT, has helped develop a new type of battery, and he proposes that such a device is critically needed for America to make use of sustainable energy technologies such as wind and solar:

If we're going to get this country out of its current energy situation, we can't just conserve our way out. we can't just drill our way out. We can't bomb our way out. We're going to do it the old fashioned American way: we're going to invent our way out working together.
He starts the talk discussing the history of the battery. The problem is that there is no battery yet available to meet today's main needs: "uncommonly high power, long service lifetime and super low cost." (min 4). He indicates that it needs to be made out of abundant elements--"dirt cheap." His proposed liquid-metal battery consists of magnesium, antimony and salt (min 10). He adds that prototypes have worked well, and they have "no moving parts . . . minimum regulation . . . no thermal runaway . . . designed to work at elevated temperature that come from current surges . . . reduced cost by producing fewer larger units . . . "

Or maybe we could say, “Good for the Chinese”

When someone from another country does something impressive, Americans are well-trained to be threatened. We are teaming with ressentiment. Here's an example from the July 18, 2011 edition of Time Magazine. Notice the photo on the right. It is an image of a brand new extremely long bridge, the longest sea bridge in the entire world. It is more than 26 miles long. It's extremely impressive. It is something that reminds me that the Chinese people have excelled in many ways. But notice the text under the photo. Especially notice the line: "The Jiaozhou Bay Bridge is yet another Chinese nose thumbing." Where does this writer get the idea that the Chinese have built the world's longest bridge to make the United States look bad? I hear this attitude all the time, exemplified by statements like this: "America is the world's greatest country." Despite the fact, of course, that there is much room for improvement in modern day United States. Many of these comments I hear uttered by Americans are aimed at the Chinese; for many Americans, anything impressive done by Chinese people is a threat to America. More disturbing, I fear that this ressentiment of outsiders builds into paranoia about outsiders and fuels the "need" for exhorbitant and irresponsible warmongering by the United States. I remember that in the months prior to 9/11, there was intense building hostility aimed at the Chinese. Then we got distracted by the Middle East. It seems that Americans intensely need an enemy, and that if they don't actually have one, they invent one. That is a destructive technique most of our politicians use to maintain power and obeisance of the governed. I'd recommend that Americans, especially those involved with the American media industry, work harder to keep their ressentiment in check. Time should have reacted to this amazing bridge by saying something like: "That's amazing engineering and construction! Well done, Chinese people." I'm afraid, though, that this attitude of being happy for the successes of others has become thoroughly un-American.
