Agreed, in my relatively car-friendly city I find for distances between 0-2 miles per hour biking is almost always faster, over longer distances the car will win, but there's almost nothing i NEED my car for
I don't find that depressing at all. As nice as H2 sounds on paper, when it comes down to it, we're already using the ideal fuels for transportation. Liguid hydrocarbons have far superior energy density compared to other options, they're liquid at room temperature, stable, require no special containment, are basically insensitive to temperature extremes, and very scalable.
Until there's and alternative that does nearly as well in all these categories, i think the most feasible eco-solution is finding ways to displace conventional petroleum (biofuels and whatnot)
according to Engadget, not only is it wildly expensive, but it's painful to type on. I wish form followed function a little more often in the gadget world.
The article doesn't say the device is good for 60%, it states IF they are able to design it to work with with high-temperature ceramics, and IF it is able to reach 600C, then CARNOT efficiency is 60%, of which this device will obtain some fraction.
I didn't see any details on how this is any better than century-old heat engine ideas, unless the solid state design allows dirt cheap mass production, in which case he might be onto something...
The weight distribution will be such that the rear wheel is loaded more heavily (%wise) than any driven wheel of a 2wd car.
This car is probably not going to be a good choice for a climate with a lot of winter weather. Were this type of car to gain widespread acceptance, a model could be designed with tiny wheel motors in the front two wheels (maybe a few HP), something to help the car get going on low traction surfaces without contributing much weight. The rear wheel would still offer most of the motive force at speed.
The reverse trike configuration has fantastic possibilities for efficiency. Right off the bat you save rolling resistance by losing a wheel, and lower drivetrain losses as well. The weight and cost savings of doing away with driveshafts, universal joints and differentials are significant. The layout also lends itself to aerodynamic 'teardrop' shapes where a 4 wheel layout makes this difficult.
Dynamically, a reverse trike with correct weight distribution will handle just like a 4wd car, or better (google t-rex). The four wheel layout is statically indeterminate, and as such, when cornering one wheel is carrying no load. A properly designed 3-wheel won't overturn much easier than a car with four wheels either.
If the option to do so were available, I'd be first in line to lose that 'extra' rear wheel.
I currently have to use several programs and a manual fan controller to for half the capability this system offers. To read temps I have to use different programs for motherboard, case, and GPU, and several fans aren't even controllable, in hardware or software. I have little understanding of the temperature distribution in my case. Getting all this information and more into one integrated hardware/software package is a feature I'd gladly pay more for.
It's really nice to see a story of good engineering getting some play. It seems whenever engineering is in the news it involves a building collapse or something dreadful like that.
It seems like a lot of franchises are going dead due to the passing of the rights from one developer to another. This is why some sequels that fans are hoping for go unmade. I suspect the same would be true for remakes.
That being said, I'd love a System Shock 1 remake. I just recently replayed the game on modern hardware and was stunned by how well it had held up graphically for a 13 year old title. And the story and gameplay is great. I think remakes are useful only when there is a storyline worth preserving (more like movies in that regard)
While the stealth=aggression argument is a slam-dunk for bombers, I would disagree with this assessment for a fighter. A non-stealth fighter would have great difficulty successfully defending against a stealth-capable agressor. I don't think this aircraft will encounter treaty difficulties.
I've seen almost this exact post elsewhere, but it bears repeating, thanks for posting.
To be honest, I felt slightly sick seeing the words "cannot cause visible, permanent injury" There are *a lot* of groups that should never have this capability.
madness. pork tenderloin is AMAZING. But then again I'll eat most flesh. I tend to draw the line at "obvious land mammal organ tissue" Any other meat or seafood is probably fair game.
Light cars have the advantage of handling and braking better than heavy cars (all other things being equal). That's a big +2 for safety for all you keeping track at home, it also 'counts' way more frequently (how many times a year do you swerve or stomp on the brakes, vs how many catastrophic head-on collisions per year).
Mass is a penalty in almost every situation, the only exception I can think of being impact with a less heavy vehicle. It's unfortunate that some think this outweighs all the other benefits to low mass vehicles.
I dream of a day when I can buy a sporty 2000lb or less car that's not an Elise or a homebuilt.
TFA states that the camera takes 20 frames per second. Aren't most exposures of deep space objects on the order of seconds or minutes (or longer). Seems like 1/20th of a sec wouldn't cut it for all but the brightest objects.
Lowering the limit is an example of going at the problem from the wrong side. If you lower the limit to.05 for example, suddenly you'll be prosecuting people who blow between.05 and.08, you'll be nabbing no more drivers at.08 and up (in fact maybe fewer due to the time spend bringing mr.06 down to the station). How does this get any more of the real dangerous drivers behind bars? I think during relevant hours, cops on the beat should be looking for drunks, period, sure they can pull over someone going 100, but sitting around and pulling over someone doing 80 in a 65 is really going after the low-hanging fruit. You're only going to see someone weaving in and out of lanes if your out looking for it. You might even stop some tired/destracted drivers while you're at it (a traffic stop will wake you right up)
All those people who got tickets for doing 80 arent going to kill anyone, the one guy who crosses that centerline will, that's the side of the problem that should be worked on, not the threshold number (especially when devices aren't perfect)
Why do I feel its only a matter of time till the design leaks out and dick teenagers start buying them on ebay and carrying them around. I hope this doesn't work as advertised.
I wholeheartedly agree. I can not stand having mass I don't want in my car coming from equipment I don't want. I can see myself looking at kit cars in the future to get around this nanny-state legislation. I'm particularly worried about the upcoming all-cars-must-have-stability control laws. I sure hope it can be turned off.
The Gamecube version was less 'sheer madness' than the first? Good lord, I've only ever played the gamecube version, but that one already takes only 15 min to burn my eyes and melt my brain.
Steel rusts too, thats why we paint it. If either a paint or coating can be used with it, or if its water solubility can be solved, this could be a huge development.

Thanks to my tv tuner card I'm doing *both* muahahahaha...
more seriously, I question this study's results, mostly the wisdom in lumping PC power requirements entirely under the 'internet' umbrella

I wish the next one were 'Gnarly Goat', that strikes me as very funny for some reason
No comments about the semi-invisible spiders in SS2?
Those things upset me to no end, mostly because you often heard that rattling long before you ever saw anything.
I don't know if games or movies are scarier, but I don't enjoy horror movies, horror games OTOH are great.
Absolutely. Twice in fact (non-consecutively (boy I'm tired)).
but seriously, where can't you find Google these days?

He should rewrite the book "Left Behind" but with a 'geek rapture'. I'd read it!
Move all the data centers to Minnesota or Canada and use them to heat people's houses.
Or better yet! DatacenterBurgerKing with CPU-broiled whoppers.
