    It may not necessarily be batteries, but some sort of localized storage may be useful for subway and light rail. The size of the train system's electrical infrastructure needs to be sized to the peak electrical demand, which is greatest when the train is accelerating. Being able to have some storage on the train would allow for regenerative braking. Right now, all the kinetic energy of the train's motion, which is an awful lot, is lost every time the train slows or stops.

    I think for pretty much any system running on wired electricity, regenerative braking is used to dump the power back into the grid - at least I've been told that this is done for trolley buses. I would think that if the grid system is able to supply X amount of power for acceleration without difficulty, it should have little difficulty with coping with the excess energy of deceleration.

    Apple has manged to convince the "unwashed masses" that their eco-system and devices are easier to use than the alternatives, and in fact their systems are pretty well thought out and easy to use and their control of the whole eco-system has made interoperability of software and hardware pretty seamless. Non-Apple sellers have the difficult job of convincing most buyers that their possibly better features are more valuable than Apple's "ease of use", even if the "ease of use" of their devices are as good or better than Apple's. The perception of Apple being the one source for hardware, software and content (through the single iTunes channel), as well as info-syncing (iCloud) is comforting to many. The competition has a number of places the consumer might feel they need to go for hardware support (Samsung perhaps), software support (Samsung, Google, and others?), content (Amazon, iTunes, etc), and services (Google and others?). Even if there is one vastly dominant company in each of these areas, they are still going to be perceived as more complicated than getting it all from Apple - even if it is not more complicated.

    Tangentially, I think smart phones are approaching the same point that personal computers reached not that long ago - for the vast majority of customers the increased power and features of new devices are insufficient to justify upgrading their current device. When everyone in the world already has a decent smart phone the market for new phones is going to get much smaller.

    experiment (since IANAP), I do want to say that there seems to be a troubling trend amongst the best and the brightest in many STEM fields to mistake theory for reality. Theory is great and proceeds under the scientific method from empirical observation, but as we've seen throughout history, new phenomena and corner cases to arise and require theory to be amended.

    While it is certainly worthwhile to keep an open mind and question our assumptions, there are a variety of different levels of confidence we have in different ideas. The major conservation laws (linear momentum, energy, angular momentum) are mathematically equivalent (via Noether's theorem) to symmetries of the space. If the laws of motion are independent of position then linear momentum is conserved. If linear momentum is not conserved, than the laws of motion are not independent of position. (similarly for rotation invariance angular momentum conservation and time invariance conservation of energy).

    http://en.wikipedia.org/wiki/Noether's_theorem

    So this goes way beyond understanding of EM theory - if we have a case where momentum is not conserved, that will fundamentally change how we think the universe is put together. In my mind it is much much much more likely that there is error or fraud or psychosis than momentum is not being conserved.

    Back to the USA, there are already some interesting private/public delivery programs that promise to keep service costs low, too. As an example, Smartpost is an economical FedEx service that uses the USPS to deliver the last mile. Expect more of this stuff in the future.

    That last mile is where the bulk of the delivery expense is. Are you sure those other low cost delivery services aren't basically externalizing their unprofitable business expenses onto, I mean taking advantage of, the Post Office?

    "Using the Post Office" can't be "taking advantage of" in that the USPS is selling a service. Using it to deliver things in-town is what every local person is doing. I doubt very much that Smartpost is underpaying for their use of the USPS. Last mile delivery may be where all the expenses are, but the USPS is already paying most of those costs every day anyway, even if not used by Smartpost for example.

    I suspect that advertising decisions are not as influenced by actual data as we might think, and even those influenced by data, probably much of it is data that does not mean what the advertisers think it means. Listening to podcasts from Freakonomics as well from Terry O'reilly http://terryoreilly.ca/ I get the feeling that advertisement is still very much a "that feels right" type of business, and that evidence based advertisement is still the exception rather than the rule.

    Stereotypes do not always exist because of an "overwhelming preponderance of anecdotal evidence", but often because of a few experiences compounded by a lot of repetition and selective memory. It does not take much for an individual to form a negative stereotypical opinion of something - doing so has survival benefits.

It's just that I'm not 100% convinced Mr. Randi is actually trying to test for these things, and not just using the "debunking of junk science" as a rather lucrative way to become and stay an extremely wealthy man.

    I don't know how this would be particularly lucrative. "Hey everyone, I'll give you a million bucks if you can demonstrate some specific claims!" That doesn't seem like a very good way of making much of a profit. Clearly he has some incentives to not make it easy to get the money, but since it isn't his money in the first place, I don't see how it helps him become or stay wealthy.

    In this case, it clams he can heat a cup of water to 97degrees Celcius by his hands. That seems like an easy thing to test unambiguously. If true it would be an amazing blow to our understanding of human physiology and basic physics, and would have tremendous value in our search for knowledge in addition to the potential economic benefits that would come with understanding the new science involved.

    Then I think "humm, which is more likely, he isn't doing the test because it is 'too much bother' or he isn't doing the test because he knows he is a fraud?" Then I feel fine to ignore him.

    In this particular case, it is not clear exactly what Pajkic is supposedly able to do. If he is merely surprisingly resilient to electricity, I don't know that would qualify as "paranormal" - people with particularly conductive or non-conductive skin might be "special", but not outside the bounds of scientific understanding. If he can actually generate electricity or heat or light or store it and later release it, that type of thing would be pretty amazing.
