Stainless steel is for the outer skin since it has to survive launch and re-entry multiple times.

The space shuttle used thermal tiles, wasn't very light either... and were a PITA to maintain.

How do you short SpaceX? They're not even public.

They're not "limited" in that they suddenly stop working after 1000 charge cycles; that's just the rated cycle count before they expect a 20% drop in capacity.

Lithium batteries can also do a lot more shallow charge/discharge cycles; Keeping the charge within 20%-80% and it the cycle count goes up to 5000+.
 
  Even the oldest Model S on the road still have at least 90% of its original capacity.

How much is your car's fuel cost?

Wikipedia requires submitters to cite openly verifiable sources... which is something conspiracy sources won't bother doing... they are usually are self-referencing (bad source A citing bad source B, and vise-versa).. or they're deliberately obfuscating any factual data that contradicts their message.

It depends what you use it for. An RP is a great for learning and for dedicated devices..... but we know it's far from being a modern desktop replacement. My "seat of my pants" feeling is that an RP3 is about as fast as a high end Pentium 3 (Circa 2000).

There are a *lot* of dedicated use devices that need much less power then a full fledged PC. The great thing is that PC technology doesn't stand still, and that a RP20 (or whatever the equivalent of an RP3 is in 15 years) will probably be as fast as today's PC.

In this case they've been doing their "minor part replacement" is 5 years late and $4 billion over budget. They could have built a natural gas only plant with the same capacity for $700 million.

Actually, the natural gas is about half the price as coal right now (in MBTU/$) thanks to fracking. It's one of the reasons almost all major utilities are retiring coal plants or converting them to natural gas.... Aside from the other benefits of lower emissions (no ash waste, no exhaust scrubbers needed), and it's easier to ramp power generation up or down depending on demand.

It's a false comparison... Ritchie was *very* well known with computer guys; particularly programmers/developers... which Jobs hired many.

Jobs did what he did as a business, yet he also had a thorough understanding of the technologies involved; such as OOP- otherwise he wouldn't have had the rational in choosing Objective-C as a basis for his NextStep OS in the mid 1980's.. which eventually evolved into Mac OS X and iOS.

Pretty soon computers can be programmed to identify people by their behavioural norms -- such as walking gait and other body language.

Switzerland require all gun owners to pass an annual psychological evaluation to retain a gun permit. Fat chance of passing that law in the U.S.

The Clipper chip was in final development long before a Democrat took the White House in 1993... Those things don't pop out of nowhere.

Now I don't think the party of the president has a huge bearing on what those 3 letter agencies try to do.... but I can attest to a Republican presidency that shoved the PATRIOT Act down our throats.

.... What's old is new again!
