The significance of this is Elon Musk, who is the self-driving Uber of dot.com billionaires and is the hero of our times.
Well, I knew Steve Jobs well enough, and have met a few civilian astronauts and a bunch of other rich people. None of the others seem to have done so much for the long-term future of the human race as Musk has in leading the path to more affordable spaceflight.
Seriously, we need people actively looking into making those new type of batteries instead of just researching them and never do anything with the research, like we've seen for the past 5 to 10 years.
That's right! That's why my cell phone which uses more power than my cell phone of 10 years ago with a battery less than a third the size lasts significantly longer - because everyone's been "never doing anything with the research", right?
Good research results make news. Their employment in commercial products generally doesn't.
I don't "misunderstand" anything, that is exactly what the device did. It didn't precool anything, it didn't ramp anything down, it just randomly shut off when too many people had their AC on (aka, when it was hottest). And in Iowa in July, even if you did know when it was about to go off and tried to "precool" (which I assure you, does not work well), you'd be burning up long before the AC kicks back in.
Right. I should have redone my entire house in order to get a device to shut my AC off during the hottest point in the day. Got it.
Well, it beats making them into the world's most complicated airplanes as with the space shuttle. SpaceX has proven that they can do vertical landings of the first stage intact onto both land and a seagoing barge; after a trip out of the atmosphere and to about 1/5 of orbital velocity but not into orbit. They plan to do a parachute-less vertical landing of the Dragon capsule after a heat-shield re-entry. That turns out to be far less expensive and complicated than a space plane. It does turn out we need a lifting body for much larger vehicles. It still doesn't have to be a plane, though.
We don't need wings.
Not a clue. My power could have been free for all I cared, I still would have had it removed. I would have rathered live in an air-conditioned tent than a house with no AC during the hottest part of the day.
