Comment Re:Too good to be true. (Score 2) 165

It doesn't work like that. Radiative heating/cooling works via exchange of IR. You're not just giving it up; everything you're radiating at is proportionally radiating back at you. So you cool the most when you're radiatively exchanging with something that's very cold. Aka, you want to be radiatively exchanging with the cosmic microwave background, not with low-altitude clouds. That's the whole point of radiating at low absorption frequencies in the atmosphere: so that you're exchanging with space, not with atmospheric air.

Comment Autonomous car harder to do than Elon Musk thinks (Score 1) 107

Elon Musk is on record for saying that Tesla cars would drive themselves by the end of 2017, adding that it would mean full autonomy with a reliability greater than that of a human.

In my opinion, the reason why Apple and Google have pulled out is not that the technology does not work, but that it is not yet demonstrably sufficiently reliable, and that cheap sensors that make the technology both feasible and economic are not out yet.

Meanwhile the traditional car makers are content with a partnership with the likes of Mobileye just to exist in this space.

Personally I believe full car autonomy is feasible, safe and useful on highways, and has been for some time. I'm not sure about economic. The other use cases are not so clear cut.

Comment Times Change and so Should Laws (Score 1) 907

First would dispute some of your logic. The second amendment of you constitution says: "A well regulated Militia, being necessary to the security of a free State...". So to me the clear intent was to make sure that the early US government had a body of armed and trained civilians to call on to defend it should Britian, or any other European power, decide to invade. This goal did indeed make a lot of sense 200+ years ago but not so much today. However importantly the clear aim was the defence of your country i.e. not to fight against your government but to fight for it against foreign invaders. If you want to have a look at a "well regulated militia" today try Switzerland. They arm, but also train their citizens. The result is a well regulated and trained militia but very few deaths due to gun violence.

Secondly though there seems little point for the law in today's world. The US has a huge military force and it is just about inconceivable that it would ever need to rely on armed citizens to defend itself. That same force means that even you interpretation, that citizens need guns to hold the government to account, is also irrelevant today. There is no way that they could possibly defeat the US armed forces if they continued to follow the government's orders. The best defence of democracy today is the same as it has always been: the will of the people. Governments are made up of people and if enough people refuse to serve it, and many resist it, it will fall.

So I agree that there was a very good reason for the law initially. However now the actual aim of that law is being completely ignored and, in today's world, the aim is irrelevant anyway. If you cannot change your laws to deal with changing circumstances you will end up in a lot of trouble.

Comment Re:do you want $100+ oil changes at the dealer shi (Score 1) 221

Anyone that owns a performance car has been paying $100 oil changes at even a quickie lube for a while now. MY dealer oil changes are $160.00 If I buy the oil and filter myself it comes out to be $65.00 to do it in the driveway.

I'm guessing that you have not owned a car and taken it in for an oil change cince 1980? Even my Honda Civic was $70 for an oil change just yesterday at a Valvoline quick lube.

Oh and they own your docx files because it is in their format.

Comment Re:Terrible Idea (Score 1) 221

Ebay always sides with the buyer, open the case and ebay will simply refund the money paid if returning the item is too difficult. in international cases from china ebay wil even say, "here is your money, keep the item" because if the auction is marked "no returns" that means that the seller does not want it back for any reason at all even damaged so the buyer can get a refund and keep the item.

If he did not open a case with ebay then he is either very stupid or just started using ebay.
