Comment Re:NOT Samsung Exynos (Score 1) 47

Realize what now? The description said an Exynos for $30, and it isn't.

The Pi is too slow to do things at which it would otherwise be well suited, like for digital signage applications. A cheap little machine that can be stuck on the back of a TV doing nothing but running a fullscreen web browser would be handy.

Comment Re:SLS and comparing to spacex (Score 2) 132

He did state publicly that he promised NASA that he could build a rocket comparable to the SLS on a fixed-price $2 billion contract (meaning NASA would not pay a dime for budget overruns), although that price didn't include any second-stage upgrades NASA might require to meet its needs.

SpaceX is actually going ahead with their SLS-like competitor (Codenamed "BFR", I think you can guess what that stands for), and they're supposed to start testing on the methane-powered engines (Raptor) soon, which are supposed to be both more powerful and more efficient than the F-1 engines used in the Saturn V. However, without any customers paying for the R&D, BFR will take a lot longer to build than it would have if NASA contracted SpaceX to do it.

So, yeah. SpaceX offered NASA a contract to build an entire replacement for the SLS for less than a year of SLS funding.

Battery swaps are unbelievably more complex to swap than switching a standardized propane tank. EV batteries (for long-range EVs) are massively larger and heavier than a propane tank, and in some cases are actually structural parts of the vehicle. Tesla designed an automated system that works for the Model S, which knows where the bolts are on the battery to remove it from the car as well as exactly how much to tighten the bolts. It'd probably also work on the Model X, which uses the same battery packs. But what about the Model S, which won't? Now you've got to handle two different kinds of battery packs, potentially different sizes and shapes, with bolts in different places... And then, handling it for other manufacturers? It's not hard to create a charge station adapter, but handling battery packs that are completely different sizes/shapes? No way. They'd have to standardize to a degree that would be a severe restriction in car design.

Tesla is just starting their expansion, sure, but the plan shows three superchargers between Montreal and Toronto alone...

They build them along popular routes, with the plan being to have them ever few hundred kilometers. They're programmed into the satnav, so planning a road trip shouldn't be any more complicated than plugging your destination address into the car and hitting the gas peddle, with the car routing you to superchargers as required.
