New Orleans is right on the ocean, so the salt water in the air is more likely to cause corrosion problems.
New Orleans is not unique in being near salt water. If the traffic lights have a problem because of that, then they're badly designed. And yes, I have designed electronic equipment to work in salt fog, etc. Testing for those conditions is common practice. Traffic lights are not some consumer item that you have to baby. They're expensive, and they should be able to take all kinds of conditions and keep working.
First, are you talking about traffic lights or street lights? Second, if the older style bulbs produced enough heat to de-ice the fixtures, then the combined power draw of the LED's and the heaters need be no more than the draw of the old lights. Even in tropical Minnesota, you don't get snow or ice ever day. They even have a month of something they call "summer".
You're right, but they're replacing high pressure sodium vapor lamps (the ones with the fugly pinkish orange color). Metal-halide are bright white, take a while to warm up, and are usually used in places like school gyms. Occasionally I've seen them used in parking lots.
Why would I trust anything Canadians say? Underneath those obsequious manners and maple syrup, they're planning to invade America. Never let it be said the British Empire gives up easily.
Part of my town (the main streets) have LED street lights, and we have no problem with snow or ice. BTW, LED's are in the neighborhood of 20-30% efficient, so they don't run ice cold (pun intended). It may seem so though if you've only touched indicator LED's (flashing lights on equipment).
The number of crashes from buggy software is much higher with human drivers than computers. How many computers hit the wrong pedal and slam into buildings?
And you know this how? Please don't say Google, because they just say "cool, X zillion miles without an accident, blah, blah, blah". We have no idea what the driving conditions and other factors are.
Agreed. Legislatures rarely pass laws that restrict the games that lawyers can play, because so many legislators are lawyers. It's nice to have your union reps running the government.
Customer-suit exception. There's no question that one of the practices that has been seen by Congress as abusive is the tendency to use patents to go after end users of a technology rather than the company that created it. Under the Goodlatte bill as drafted, if a manufacturer and customer agree, litigation against a customer can be stayed while the patent holder and the manufacturer battle it out.
That's a good start, but needs to go further. AFAIK this is a recent practice (some idiot judge said it was ok), but it's absurd to expect a customer to be responsible for whether or not any product they buy infringes on a patent. That's the manufacturer's responsibility. How many products do you own that could, according to some troll, infringe on "their" patents. Of course they won't go after John Doe, but it's another issue when the customer has deep pockets. This happened to a company my friend works for. They lost, or at least had put on indefinite hold, sale of a lot of equipment to a very large customer, because a patent troll threatened to sue the customer. The manufacturer might take them on, but do you think any customer, no matter how large, is willing to deal with that? Talk about restraint of trade.
SSDD. Companies that complain the loudest about "not being able to find people" generally pay squat and/or are a miserable place to work. Oddly, the companies that pay decently and are decent places to work have much less of a problem finding qualified people. Glad you found a better job.
Otherwise some patent troll will go after the dolphins. This may be the only way to kill the trolls - they can be cited for interfering with wildlife or something. Kind of like getting Al Capone on tax evasion, though if you ask me, Al's business model was more ethical than the trolls'. At least he delivered product.
It involves clutter (e.g. bubbles) having non-linear reflections (presumably because they're compressible), hence they have both even and odd harmonic reflections. Something from a harder object will have only odd harmonics. Adding the reflections from two pulses, one of which is inverted, will cancel the even harmonics of the clutter.
Lawmakers have a tendency to pass laws that would crush private industries unless they intervened.
Which explains why, in the 1950's and 60's for example, when spending on lobbyists was a fraction of what it is today, the economy was destroyed by laws that crushed private industries. Or was it one of the biggest growth period in our country's history? I forget. Screw it - ideological assumptions trump facts.
To be fair, the battery technology for a true replacement electric vehicle is just getting there now.
They've been working on battery technology for over a century. They've certainly improved, but not at a dramatic rate. The next big breakthrough is always around the corner.

Ever hear of pedestrians?

Nobody said they worked underwater.

I don't think I've ever seen it snow upwards.
Never seen a good blizzard?

Yup, GIGO. Let's assume that this tech works great under real-world conditions. Then we know that it will be a big improvement. Wow, such insight.

It's more clever than that. Here's a sonar explanation anyway:

How come there's no button for Score:-17, Bad Pun?
I just realized how ironic it is that there are no umlauts in the word "umlaut".
Maybe you'd get there.
The fact that Michael Powell went from the FCC to lobbying for the very god damn companies his former office was supposed to regulate is baffling.
Baffling? No. Utterly corrupt? Yes.
To add insult to injury, you'd never have even heard of this guy if his father wasn't Colin Powell.
You're equating military service and parking spots? Wow.

to provide electricity for my flying car
I know you need 1.21GW peak power, but what's the total energy requirement?
To be fair, the battery technology for a true replacement electric vehicle is just getting there now.

I'd rather rely on experiment than speculation about how some of hydrogen's properties make it more dangerous.
I'm not saying the technology might not prove itself within a few decades
Toyota will start selling it's hydrogen fuel cell car in 2015.
The bottom line is that fuel cells work, and hydrogen storage is at least as safe as gasoline. On of the big stumbling blocks is cost. Toyota has managed to reduce the platinum requirement from 100g to 30g.
