Although in development since the 1960s, NASA has recently completed two years of cycling in low earth orbit to prove the sodium sulfur cell's viability for future space missions.
It uses sodium and sulfur as the electrodes, and a solid beta alumina ceramic as the electrolyte. The end result is a battery that produces 150 W-hr/kg on the cell level, and weighs half as much as nickel-hydrogen technology.

A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
