    He actually once showed up at a speech badly burned and trying to cover it up because he had installed a UV lamp but went way overboard on using it.

    It is a totally BS excuse. The real issue is the timing. The Swedish Court system just smacked down his most recent appeal, eliminating any hope that they're going to be dropping the case any time soon. I think he's finally starting to come to the realization that running from the accusations and trying to negotiate or blackmail them away just isn't how the world works. He's got a probable cause of rape finding from the Svea Court of Appeals, upheld by the Swedish Supreme Court, and with the warrants upheld at every level of the British court system up to and including the Supreme Court. You can't "maneuver" your way out of that. Real life isn't a spy novel.

    Honestly, I thought this realization would come after his run for the Australian Senate, under the theory that the UK wouln't dare stop an Australian senator (his campaign fell apart when he overrode the democratic vote of his party in order to break their alliance with the Greens and instead caucus with the Neo-Nazi "Australia First" party and other right-wing parties, leading to mass desertions). But... better late than never. If he does, actually, come out, that is.

    Tilbit is absolutely correct, though. Nicholai Tesla did some great work, mainly in his early years, but he increasingly started making claims without any serious experimental or theoretical backing whatsoever to drum up public interest, many of which are in complete violations of the laws of physics. A lot of his claims were based on "evidence" along the lines of "It was 30 degrees yesterday and it's 40 degrees today, therefore next year Earth will be vaporized." And in a lot of cases he appears to have outright just made stuff up.

    This isn't to diminish his earlier work. He was an excellent tinkerer and ran across some really useful concepts and worked out equations to describe and utilize them. But he increasingly abandoned that for hype as time went on.

    That makes absolutely no sense, and I fail to see what relevance it has to my comment.

    It makes perfect sense, so you clearly have no conception of what the person is proposing.

    You're talking about flying where someone holds onto a stick and manipulates control surfaces, They're talking about flying where they punch in "123 Maple Street" and the computer flies them there. One could of course allow both modes of flight, but the latter is what most people envision (or at least what I thought most people envision) when they hear "flying car".

    Beyond that, I would like to add that while flying introduces new risks for manual piloting, it also removes a lot of them. Both commercial pilots and long-haul truckers in remote locations have similar roles in terms of spacing between vehicles and time behind the wheel, but only one's job is easy enough that they can have an autopilot do it for them for 90% of the trip. Yeah, someone cruising at 20.000 feet might be doing their makeup or texting on their phone, but at least they're not going to hit a tree while doing it.

    (and yes, I know that if you replace all cars with planes, the skies get a lot more crowded, which is why I compared to a remote-location trucker, just to point out that the basic situation is easier in 3 dimensions where one's "lane" is much wider, there are no ground obstacles to hit, no hills, no bends in the road, etc, and traffic is split up among many well-spaced layers that are easy for a plane to maintain... no, millions of drivers cannot fit into our ATC system as-is, and I'm not claiming that, it requires a new system with greater automation)

    Also, I'll add that you missed the obvious criticism of flying cars - the "dropping out of the sky upon failure" one ;) Any realistic "flying car" is going to have to have some really dang good failsafe mechanisms not only to protect its occupants in such a case, but people on the ground as well.

  9. Re:Supplant Niche on Where are the Flying Cars? (Video; Part Two of Two) · · Score: 1

    Disagree. A good car doesn't have down force (beyond gravity), downforce means aerodynamic drag, a good car should rely only on the force of gravity for its grip. The things that help a plane also make a car more fuel efficient - streamlining and lightweight construction. Cars have slightly different streamlining reqs due to operating near the ground, but the general principles are the same. Of course you've got wheels out there, but so do many light planes. Lightweight construction is often described as the opposite of crash safety, which is very important in cars, but with foam core composites you can have both.

    As for the GP's comments: I don't think anyone really expects your average driver of a flying car to be behind the stick controlling flight surfaces; I think most people envision something more like a good quadcopter where everything is managed for you by control software that maintains position and attitude (despite changes in balance, wind, etc) or even fly preset routes / automated traffic management. People don't envision runways, they envision VTOL. They envision not a helicopter (non-roadworthy, giant exposed spinning prop), but something roadworthy with nacelles.

    One big former problem with flying cars was the weight, size, cost and complexity of the sort of high power engines you needed for them, and if you needed multiple engines (quadcopter-style), then all the more problem. It pretty much ensured that your flying car would have a supercar price tag. But electrification of transportation looks to be solving that one - high power outrunner electric motors are very simple and have just ridiculous power to weight ratios. Battery energy density is still a problem (and would be even more of a problem if your lifting surface area is limited and you lose a little efficiency to your prop geometry), but it's constantly improving, the percentage rate of growth on electric passenger airplanes is even faster than that of electric cars (although starting from a much smaller starting point, mind you).

    No, I'm not saying I envision the world suddenly switching over to flying cars - far from it. I'm just pointing out that the problems aren't as intractable as folk often make them out to be.

    Both are terrible, and started going downhill around the same time, racing each other to the bottom - beginning in 2005 (when you started getting shows like Deadliest Catch and Decoding the Past, which became the prototype for many future series of increasingly less "reality"), and then full force by 2007 where you start getting too many shows to name.

    One thing that drives me crazy almost as much as the blatant pseudoscience presented as fact is the extensive acting presented as reality. I mean, okay, I get it, a purely "reality" program is pretty much impossible, the very requirements of filming it make it so. Even in stuff like Les Stroud's "solo" work he always had a base camp just a couple kilometers away from him and stayed in communication with them by radio. But now the stage guidance, product promotion, and "weekly scripted adventures" have gotten so absurd and obvious, they don't even try to hide it any more. I thought that they couldn't get any lower than the bogus survival show Man vs. Wild (where the host pretended to be living in homemade shelters and surviving off wild food, when he was actually staying in luxury hotels and show consultants prepped everything from making "rafts" for him to releasing "wild" animals for him to catch). But now almost all of their shows are like that or even worse. And the product promotion, my god - have you seen the Pawn Stars plugging for Skype? If you're going to have your "reality show" stars plug a product in your show, at least get people who can act.

    The changes are so visible with time, too. Take Mythbusters for example - watch some of the early eps and compare with the modern eps and look at how much more is obviously staged acting with everyone reciting a script (not to the extent of Smash Labs, but still). Apparently Discovery Communications has decided that this is what people want to see - bad actors going on "daily adventures" and having "witty banter".

    My BS detector went off when I saw that graph, so I had to actually read the paper... and now I understand the graph and it's not at all what it seems to be.

    See that giant circle for silver? That doesn't mean "a massive amount of silver", or even "a massive amount of environmental impact from silver". These circles are sized proportionally to how much more of a resource is needed than in the current generation mix, if all power came from that source. Since almost no silver is used in the current generation mix, anything that actually uses silver - even if a rather small amount - will dramatically inflate its circle.

    In all of the study's graphs, the amount of silver used is so small that the bars don't even register one pixel tall, so you can't really estimate how much they're talking about. The only graph where you see any height at all, Fig 8, is the graph relative to total world production - but even in their highest scenario it's less than 0.5% of world production. And the study itself notes, "Silver in PV cells might be replaced by other metals". Silver has only a 6% better conductivity than copper, it's not a big difference. And if you're willing to use slightly thicker or more frequent connects, you can use cheap and hyper-abundant aluminum. Either way, the amount of metal involved is practically irrelevant, the interconnects we're talking about here are practically microscopic.

Your mere 700 commercial-scale wind turbines (less than 2% of the US total) would have long ago driven to local extinction any bats in your area.

    The reality, of course, is that estimates for all bat deaths from wind turbines in the US combined range from about 30k per year to 800k per year. All combined.

  23. Re:More Range Needed on Stanford Team Creates Stable Lithium Anode Using Honeycomb Film · · Score: 1

    Actually, 800 is quite a sensible number. At an average speed of 60 miles per hour (aka, factoring in driving / bathroom / meal breaks), that's 13 1/2 hours of driving - a good day's drive. Throw in a few more hours driving time / a couple hundred miles more range if you charge while you're taking your breaks. Once you get that sort of range, charge speed becomes virtually irrelevant because it happens while you're sleeping (and getting ready for bed / getting up in the morning). A regular Tesla home charger could handle that sort of load.

    I agree with you that a half hour charge isn't actually that onerous, but it definitely will scare off people who are used to filling up faster. And charge stations that can do half hour charges on 300 miles range (150kW+ for an efficient car, more like 250kW for a light truck) are exceedingly rare as it stands. A charger that powerful isn't some aren't some little wall box with a cord hanging off of it, it's the size of a couple soda machines put together (bigger if you add a battery buffer so that you don't need a huge power feed) that feeds so much power that its cable has to be liquid cooled and which costs around $100k installed. Ten minute charges are, of course, around three times that size. I've only ever come across mention of *one* charger in the ballpark of the required 750kW to charge a 300 mile light truck in 10 minutes - an 800kW device custom made a couple years back for the US Army Tank Command. I have no clue what it cost, but I'm guessing "Very Expensive".

    I'm not saying that the problem is intractable, by any stretch, I totally believe that we're going to transition over to EVs. I just question the sort of time scales that a lot of people envision. The average car on US roads is 10 years old. Implying an average 20 year lifespan. And many cars don't get scrapped then, they just go to the third world. Even if you suddenly switch all new car manufacturing over to EVs, you're talking decades to replace them. But of course you can't just switch over like that - even if everyone was right now sold on the concept of EVs with current tech, you're talking at least a decade, possibly more, to tool up to that level of production. But of course, not everyone is right now sold on the concept of EVs with current tech.

    Realistically, you're looking at maybe a 40 year transition. I hate to say that, because I love EVs, but I'm not going to just pretend that the reality is other than it is.

    I'll also add that while fast chargers are big and expensive, the size and cost actually are comparable to building a gas station on a per-pump basis, and the economic argument works out for making them even if there's only a reasonable (50% or less) surcharge on the electricity sold and if they're only selling electricity a couple percent of the time. But you need to get a couple percent of the time usage to economically justify them - one person stopping for 10 minutes every few days just isn't going to cut it. And not every EV is going to stop at every charger even if they're driving on the same route - if your chargers are that far apart, then that means you're pushing people's range so much that they're not going to be comfortable driving that route. All together, this means that if you want to have fast charging infrastructure economically justifiable in an area you need high EV penetration, where several dozen EVs driving long distances will be going by each charger every day - even out in the boonies. And when you're talking at prices on the order of $100k per unit, you're no longer talking about a range where peoples' goodwill toward EVs or interest in having a loss leader outside is going to pay for them.

    Basically, while busy interstate routes on the coasts and the like can economically justify them with a small fraction of a percent of people driving EVs, out in the boonies, they're going to be stuck with smaller, cheaper, slower chargers for a good while. Unless people are willing to pay a big surcharge on the electricity sold, that is (500% surcharge instead of 50% = 1/10th as many vehicles needed).
