My company invents all kinds of new technology in lots of different areas. And we do that for a couple of reasons. We invent for fun - invention is a lot of fun to do - and we also invent for profit. The two are related because the profit actually takes long enough that if it isn't fun, you wouldn't have the time to do it.
The depressing thing about battery technology is that it gets better, but it gets better slowly. There are a whole bunch of problems in materials science and chemistry that come in trying to make existing batteries better.
If you had a really good - battery, it wouldn't matter that the sun goes down at night and the wind stops blowing sometimes. But at the moment, battery technology is nowhere near good enough to use at utility scale.
The NeXT purchase is too little too late. The Apple of the past was an innovative company that used software and hardware technology together to redefine the way people experienced computing. That Apple is already dead. Very adroit moves might be able to save the brand name. A company with the letters A-P-P-L-E in its name might survive, but it won't be the Apple of yore.
Within NASA, the shuttle is perhaps the least-groundbreaking project. Recall that Apollo was about creating brand-new technologies that did something unprecedented - putting men on the moon. The shuttle is, by comparison, a relic designed to make going into orbit routine.
