Metro Pittsburgh: no problems. Spotty service near Wilmington, NC and unuseable in carolina beach. Yet Jacksonville, NC is great. Had issues in past with spotty service in mid Long Island but ATT must have upgraded there. Service was good on last trip. Queens/JFK area is also OK.
Funny you would call diesels gutless. Why would GM, Ford and Chrysler rate their biggest V8 Gas pickups at ~10,000 lbs maximum towing capacity when their 6 cylinder Diesels are rated at up to 18,000 lbs? Why do 18 wheelers use diesel engine instead of gas? Because they're gutless?
The problem is less about the concept of drones and manned aircraft in the same airspace than it is about the absolute explosion of drones circling to monitor traffic for the TV stations and traffic speeds by the highway patrol once the cost of doing it falls by an order of magnitude by removing the labor cost and weight of the pilot from the aircraft. Unchecked, there will be five times as many aircraft in the air around big cities. This kind of traffic level is totally unmanageable. And drones will fall out of the sky just as manned aircraft do. And when they do, the sheer quantity of aircraft in the sky will mean they likely take other aircraft with them. That's what has the FAA scared shiftless.
Yes or we could triple the thermal efficiency of the Internal combustion engine to 90% and overnight cut by two-thirds the worlds motor fuel requirement. This could be a simple retrofit to any gasoline or diesel engine and shouldn't cost more than US $5.00 per car.

This car solves two problems, first how do we efficiently store energy on the order of gasoline, Batteries don't cut it and ethanol is not going to replace oil ever, there's not enough farms to grow enough corn or sugar cane. Hydrogen looks like the only alternative. But who is going to invest in a hydrogen distribution infrastructure until there are cars to use it? And who is going to buy a hydrogen car until there are hydrogen filling stations? This car can use conventional oil or hydrogen, thus a bridge technology to hydrogen fuel cell electrics.
Electric motors are more efficient than what? The motor itself is great but how do you power it? Batteries are vastly inefficent (ever feel how hot your laptop gets when you charge it or use it, that's wasted energy), heavy for the power they store and the transmission media to get the power to the battery charger has losses associated with it. the manufacture of batteries is very environmentally unfriendly. Also batteries don't store energy well long term - they go flat. Hydrogen isn't a power source, it's rather a energy storage medium, like a battery. and the weight of an equivalent amount of energy in hydrogen is much lower than that in any battery. That's why NASA uses hydrogen fuel cells and hydrogen rocket engines.
Battery technology has had a lot of money thrown at it by GM, DARPA, NASA and the computer industry for years. It's time to throw some money at hydrogen technology as an alternative. Oh and as a side benefit of hydrogen, it can be used in vehicles such as these BMW's which solve the chicken or egg problem of do you buy a hydrogen car when there's now hydrogen filling stations or do the oil companies start creating a hydrogen distribution infrastructure when there are no cars to use it?
Yeah that's exactly what we need. More misguided laws to try to correct the unintended consequences of the last set of misguided laws. It's simple folks. If burning fossil fuels is bad, tax the consumption of fossil fuels. Then free economies will decide the most cost effective alternative. It's obvious that's not ethanol.
One other thing though. Just because the developed world quits using fossil fuels doesn't mean that all the developing countries(China inclueded) in the world won't just compesate our conservation by burning more. After all, once we stop using it, it will become a lot cheaper.
Yes and centrally planned and regulated economic markets work so much better than the free market. Look at the successes of the Soviets, North Korea and East Germany. We just need to force those awful oil companies to build new refineries in Yosemite and drill the North Slope, and produce, produce, produce!!!!
Or maybe not. Maybe we need to force them to build wind farms and solar panel farms and produce, produce, produce!!! never mind that the electricity they produce will cost 10 times the going market rate and that they'll be bankrupt in 2 years. After all, they're just evil corporations.
I agree with everything you say in the first three paragraphs but your conclusion is where it all falls down. the bottom line is our government is lining up to put mass fortunes into "cultivating" the ethanol industry for a very small 1.3 to 1 return. It doesn't make economic sense. And to waste any more limited financial (especially public money) or intellectual capital on ethanol is wrong. Rather than an earmarked subsidy for ethanol, why not a level playing field subsidy for all alternative energy technologies that show potential to reduce oil imports, or greenhouse gasses or whatever the problem is that we're really trying to solve. Better yet, just tax oil at a higher rate and let the free market find the most efficient alternatives. My guess is that 90% of that solution would be greater conservation.
Battery technology has been the stumbling block for electrics/hybrids for as long as they've been talking about them. And a viable battery has always been a few years out on the horizon. GM has sung this tune before, I'll believe them when they ship the car.
Yes but how dare Apple create their own DRM. They should have rolled over and paid licensing fees to MS for their DRM. At the same time they should have killed quicktime and abandoned the industry standard.mp4 format and used.wma for the iPod. The nerve of Apple!!! Steve Jobs just doesn't know his place!
The people that built the damn internet don't manage the systems any more. Take a gander at OMB Circular A76 (for those that don't know and don't care to llok it up, it's a directive from the Office of Mangagment of Budget that directs agencies to contract out for their help). Bid out all your IT administration to the low bidder and see what happens. Right now if the agency I work for buys me a new Dell, the IT contractors may get around to configuring and installing it for me within six months. It's obsolete before it ever makes to my desktop. And they won't give a senior level electrical engineer administrative rights to his own desktop, so you can't do it yourself.
Yeah cringley and Dvorak only post this drivel to drive traffic on their web sites. just like Slashdot and all the other news sites that have already posted Cringley/Apple/Adobe headlines today. But it's fun to read and dissect wild speculation. Otherwise there wouldn't be so many posts on/. to this column.

Time to launch a new initiative: "One Warranty per child"

Nothing to do with the L-M contract which is flight service stations and not Flow control (where the Linux boxes will be used).
This is one system used for flow management (planning of routes and clearances but not actually Air Traffic Control)
TMS was hosted on Apollos using Sys5
ETMS migrated to Sun/Solaris
TFM-I upgrade replaced ETMS
You'll be pleased to know that the Air Traffic Control radar systems dont use Windows either.
