Comment Re:Subs as aircraft carriers (Score 1) 75

Cruise missiles work great for blowing stuff up, but there are a great many operations that call for extraction of soldiers or intelligence. Submarine-based aircraft could do this very well.

Some security strategists have proposed the florida-man-piloted-gyrocopter was allowed to land safely on the capitol lawn in order to give the North Koreans a false sense of confidence in their secret submarine-based gyrocopter assault project currently under development near PoonYang.

Actually gyrocopter rotors and helicopter rotors use exactly the same types of airfoils. The only difference is that a helicopter can use an engine to turn the rotor, while the gyrocopter uses the airflow through the rotor to turn it. Helicopters do exactly the same thing when we glide with the engine shut down/disconnected. There are many different designs, but generally speaking gyrocopter and helicopter rotors are identical except that helicopters may use an engine to power the rotor.

If you want to check out a couple links on my helicopter website that discuss this:

Your blowing it out of proportion. The guy didn't endanger anyone.

So if that gyrocopter developed trouble on his approach, and veered 20 degrees to the left on its way down, which would have put him into a crowd of kids and tourists, no big deal?

Granted, only a few hundred people have died in gyro accidents since they became popular.

Actually I think you're the one blowing it out of proportion. The no fly zone isn't there to protect the kids and tourists, otherwise there would be no fly zones over every major city and populated area. It's there to prevent terrorist attacks which this guy took some reasonable (but not foolproof) steps to make sure nobody thought was what was going on. Yes, if he had aircraft problems he could have endangered people, but that's the case with every airliner flying into every major city. As a helicopter pilot with a couple hours in gyrocopters, I think it's pretty safe to say that he posed a very small and manageable risk to kids and tourists on his approach path.

My only problem with the stunt (I think it was pretty funny/cool mostly) is that the government will no doubt feel they need to further tighten security around D.C. in order to prevent future embarrassment. Luckily I'm in Boston with few requirements to ever fly in that airspace - in general I would avoid it like the plague but this will probably make it even worse.

As a pilot, I would never fly an aircraft which has a remote capability to take control away from me.

Fair enough, why? What specific objective reason(s) causes you to oppose the idea completely? I'm not for or against the idea but I'd like to hear why it is a good or bad idea. I understand the issue of situational awareness by the remote operator could be an issue. What else?

Because when I'm the Pilot In Command it means exactly that: I'm in command, and I'll pay with my life for the mistakes I make. That won't be true of people on the ground. If you don't want me in command, don't put me in command in the first place. I again refer to United Airlines 232. Why did that crew save 2/3 of the passengers when subsequent attempts in the simulator by other crews failed 100% of the time? One reason was probably motivation. Their lives were on the line. As a passenger I much more likely to trust the crew who's lives on are the line, than some guy on the ground trying to second guess them.

Also, I very much doubt you can construct a safe system which allows you to take control away from the crew. How do you implement that in a way which can't take control erroneously, yet can't be disabled by a suicidal crew? I very much doubt it can be done.

To suddenly decide that we can't trust the crew despite the fantastic safety record aviation has is just ludicrous.

Agreed though that also doesn't mean we shouldn't analyze the situation thoroughly to see if anything can practically be done. I generally share your sentiment that the safety record of aviation is great but it got that way by carefully examining disasters to see if any improvements could be made. Maybe there is an opportunity of some sort here to introduce improvements.

I said that in the original posting - more screening and evaluation of crew is probably needed. And the USA rule of "never one person alone in the cockpit" should be adopted world wide. But trying to take command away from the crew while in flight will cause many more problems then it would ever solve.

As a pilot, I would never fly an aircraft which has a remote capability to take control away from me. As a passenger, I would never fly in an aircraft in which remote control could be taken away from the crew. I don't even think the "remote copilot" is a good idea. There are a lot of good reasons to fly with a crew of 2... it's not just workload and risk of incapacitation. When things get weird, it's good to have another person to bounce ideas off of. United Airlines Flight 232 is a great example of that, and there are plenty more.

This isn't the first time we've seen suicide by the crew, but it's extremely rare (I can think of maybe 5-6 in 40 years). It sucks to be the people in the back when that happens, but it also sucks when an airplane drops on your house and kills you and your family. I'm as worried about one than the other which is: not very. We can improve the situation some: better screening of crew, USA style "always two people in the cockpit" rules... To suddenly decide that we can't trust the crew despite the fantastic safety record aviation has is just ludicrous.

 

Comment Re:Cut the vitriol, talk science (Score 1) 330

Interesting calculations. I'm going to suggest that they may be weighted worst case for the EV though. I think it's very unlikely that you're going to see 100% of the fleet need battery replacement at 100,000 miles. What nobody knows for sure is what that number will actually be, but my gut tells me it'll probably be somewhere between 150,000 to 300,000 miles typically. But let's ignore that for a minute. The other assumption you used was 20K for the 85 kWh battery pack in the Tesla. But the Tesla is the luxury car of the EVs. I'd like to offer some other numbers (For my Honda Fit EV). Now, my car is a lease only, but I think the Leaf owners can comment that I think the Leaf will be pretty close. The Honda Fit EV has a 19 kWh battery. Let's assume for argument's sake that we prorate the cost of replacement based on the capacity, so $4470 @ 100,000 miles instead of $20,000. I'll still use the 100,000 mile figure even though I think it's way too conservative. I'm also going to work the calculations assuming $0.12/kWh which is what I pay. I've been seeing 100 miles in the summer and 50 miles in the winter, so I'll assume 75 miles from the 19 kWh battery, even though it's probably better than that (winter isn't 6 months, but we'll assume it is).

100,000 miles: electricity==$3040, battery replacement==$4470, total==$7510/100000 or $0.08/mile
150,000 miles: electricity==$4560, battery replacement==$4470, total==$9030/150000 or $0.06/mile

an ICE car assuming 30 mpg @ $3.00/gallon here in the US right now:
100,000 miles: gas==$10,000, oil changes==$1,000 regular 30/60/90 inspections==$1,000 total==$12000 or $0.12/mile

So, assuming the battery pack cost is proportional, a small EV like the Leaf or the Fit EV is cheaper to operate than the ICE car even assuming 100,000 mile battery pack replacement. But it's probably not even that bad, because as someone else pointed out, once EVs are popular there will almost certainly be shops that will replace bad cells in your pack for a nominal fee. If we assume that for half the cost of the battery pack we can get the car to make it to 250,000 miles (which I think it will probably make without pack servicing) then we see numbers more like:

250,000 miles: electricity==$7600, battery servicing==$2235, total==$9835/250000 or $0.04/mile.

I don't think that's overly optimistic, but it's certainly not pessimistic. I think the ICE numbers are overly optimistic - I don't think many ICE cars make 100,000 miles with only $2,000 of scheduled and unscheduled maintenance, but even if we go with those numbers, a smaller EV is substantially cheaper to operate than a comparable ICE car. I also think that if you rework your numbers to compare the realistic cost of operating a BMW M5 versus the Tesla, it will be a lot closer than your numbers initially indicate. I'd actually expect the Tesla to be moderately cheaper than the BMW when you figure in all the maintenance costs on the M5...

The thing that still makes EV expensive is the initial cost. Right now the small EVs are probably carrying $10,000 to $15,000 extra cost over the ICE version of the car, so if you add that into the equation for the Fit EV it brings the price up to around $0.18/mile which IS more expensive than the ICE car. If we can see manufacturers get the initial price down to be more in line with the ICE cars, then I think the EV can easily be price competitive.

In closing, I'm glad you worked out some hard numbers instead of the regular hand waving that's so typical on Slashdot, but I hope you'll consider that your equations might have been a bit skewed and that the reality is that even with EVs being brand new on the road, the operating costs are more than competitive with ICE, and hopefully we'll see initial prices drop to make them overall competitive with ICE cars.

BTW, the Honda Fit EV is a great car and I'm sorry that Honda doesn't seem to want to compete in the EV market (hydrogen is dumb, I think). I'm anxiously waiting to see what the Tesla Model 3 ends up looking like: if it's competitive with the BMW 3 series for $45K or so, I'm planning on buying one.

Comment Those Katrina trailers cost $19,000 (Score 1) 79

These exo shelters are not meant to satisfy the requirements of the FEMA trailers used after the hurricanes, first of all. Those trailers were issued to people months after people had applied for them. It was a long distribution process with people living in group shelters waiting for the trailers to arrive.

Per this article, they also cost $19,000 in 2005 dollars. Much more than the $4000 you're estimating.

These exo shelters are a more immediate shelter solution. Deployable within hours of an emergency event. Consider the people recovering in Haiti after their big earthquake or the people sleeping on the floor of the Superdome after Katrina. FEMA trailers were not available or provided to those people in the hours and days after the disaster. These exo shelters are a possibility, though.

Comment Re:Cost (Score 2) 79

The exo shelters massively dominate over FEMA trailers on the criteria you have proposed here.

These nest inside each other, so you can lay about ten or so on a flatbed trailer. I think you could get two FEMA trailers on top of a flatbed trailer.

Cost? Well, a FEMA trailer needs to be constructed to highway transportation standards. Do you think that's cheaper than building something to "more durable than a tent" standard (exo shelter)?

Comment Halliburton builds the robot factories (Score 1) 294

Terminator isn't the scenario Elon and Steve are talking about. But it's a model that still fits their concerns.

Automation applies economic coercion to the laboring humans to serve the interests of the automation. For instance, Watson is an AI technology that is being positioned to lay off a lot of people in phone call centers and taking orders for drive-up windows. Actually, Watson is being aimed at a lot of jobs. All those displaced workers cascade to flood the job market. Maybe they get some training to compete for trades such as electricians, plumbers, and taxi cab drivers. With so many available applicants, the wages for those jobs go down. The economy for the middle class tanks. With people desperate to feed their families, do you think they'll really scrutinize that ad looking for workers to build the drone factory? The drones that are intended to fire missiles at the 'terrorists'?

AI is a wealth concentrator. That's what Elon Musk and Steve Wozniak are talking about. It is increasingly developing the capacity to eliminate millions of blue collar jobs in order to enrich people with white collars. The Terminator series is a colorful depiction of this process.

Absolutely correct. Neither godaddy or network solutions are technology innovators. They are merchants of a commodity service. They are running a business model of attracting suckers as customers and providing minimal service (i.e. outsourced to India) while sneaking fees in at any given opportunity.

Good analysis here, Shanghai.

In terms of the prediction of "$360/TB off a $30/TB investment", does that take into account redundancy to protect their liability for drive failure? I'm thinking they have at least two copies of everything a customer uploads. Maybe three. It's still great money, but I think the numbers are more like $360/TB off a $60/TB investment.
