"What can I do to reduce my emissions" is the wrong question to ask, because most people don't care that much about reducing their impact. Even if everyone who cares could somehow cut out 100% of their emissions, it would o

I think the patent-sharing thing is an interesting point, because I agree that it suggests a certain amount of altruism, but at the same time I think it's still the right business choice for Tesla. Instead of looking at the situation t

This analysis leaves out a critical factor, which is that the distributed system will start re-replicating each partition once nodes are declared to be lost. Clearly, if this can be completed before any other nodes fail, no data will be lo

For a more in-depth analysis of these kinds of effects, see: http://web.stanford.edu/~skatti/pubs/usenix13-copysets.pdf The authors basically try to determine "if all data is replicated to N nodes, how can we

Well, to be fair, a malicious person could just as easily shine a beam into the optical sensors on my face. If someone really wants to cause an accident, it's kind of hard to stop them, regardless of whether you're in a self-drivi

I agree with you that this is probably overblown. But, just to play devil's advocate, it seems plausible that sunlight might activate some kind of defense mechanism in the eye that protects it from the effects of the higher energy part

> Tesla is neither at scale nor profitable. They're selling barely 15,000 cars per quarter, compared to Toyota's 2.5 million. Tesla's sales last quarter were 24.5k cars, hardly "barely 15,000". Q4 is expected to

Some do that. The Mercedes B-Class Electric is one example. Tesla is more "honest", so you actually get to see the full capacity. This does mean that you can see the capacity very slowly decrease over months and years, but I would

Republicans already had a majority in the house and senate, and have tried to repeal the ACA many times. They still don't have a supermajority in the senate, though, so I expect Democrats will continue to filibuster any attempts to rep

Yes it would. But if we can switch from a losing game to a zero sum game, that could still help prevent more climate change in the future. Right now, the best solution in most cases is probably renewables and batteries. But this could be a

The Tesla battery pack comes with an 8 year, infinite mile warranty on all cars. Some small amount of capacity loss is considered normal over time, but from what I've read it's generally been pretty minimal. My own Model S is only

Yeah if there were parking garages or lots where every parking space had a charging port, that would be awesome, and could actually be part of a practical solution in the long term. Unfortunately most garages I've seen have somewhere f

Unfortunately, most of the public charging stations out there are pretty pointless due to their slow charging speed. Without faster charging, you can't do long-distance travel (nobody wants to stop for 4-8 hours in the middle of a road
