My ICE car has effectively unlimited range as long as I stop to refuel

FTFY.

And you're conflating range and convenience. that's a no-no.

So while it takes several hours for a model S to get 100% charge, it reaches 80% charge (and therefore range) in only 30 minutes at station with a Supercharger station. And I don't know about you, but I need to stretch my legs and rest a bit after driving 180ish miles. so stopping every 3 hours is still roughly in line with typical driving practices, especially if you have the family (and kids!!) along.

The breakeven point for that 12k price difference between you and the GP (assuming for a rate of 10k miles/year and fuel economy of 30mpg) from the cost of gas is between 8 and 14 years (includes the cost of electricity to charge the car).

The average ownership length across all cars is 10.5 years, and creeping up.
The average ownership length of new cars is 6 years, and increasing even faster.

Costs of EVs are coming down, rebates and tax credits increasing, range increasing.

The economics of it just keep getting better and better every year.
I expect parity within 5 more years, and an EV surge following that.

EVs cost significantly more than gas cars

Only if you only compare upfront costs and costs over the life of the vehicle.

don't have the range of gas cars

Depends on model, but as a blanket statement it's patently false.

apartment dwellers have no way to charge them overnight

Depends on your complex, but as demand increases it's not at all unreasonable to think that charging hookups will become more common in parking areas, particularly of residences like apartment complexes.

Comment Re:LED based street lights and movement sensors? (Score 1) 307

normally I dismiss this "internet of things" as silliness. but here is an exception, where our autonomous cars can communicate to the road and the low power high efficiency streetlights can turn on as required (predictively, from knowing our destination) as we travel, and shut off again once we pass by.

as for retrofitting existing sockets with sensors, yes. home depot, lowes, grainger, and other building supplies stores sell them in various capacities (higher ones need more specialized suppliers like Grainger or WESCO).

No, you won't find this on a small cruiser - but you also don't find the poor little cruiser out in the middle of the ocean by itself.

Actually, yes, you do. The Navy does a lot more than just sail around in full carrier centric battle groups.

I imagine newer boats have full on CNC machines.

They don't.

I hate being only able to see a few dozen stars at night, and I'm live in a fairly rural area, and out "city" isn't all that big.

Travel a couple hours any direction, and it gets better, enough that it literally dropped my wife's jaw (she'd never seen it before), but it's still not like I used to get see in the middle of the Nevada desert or from the top of a ridge in the Northern Sierras at night.

As much as it's oh so fashionalbe to break into hysteria "Them Drowne ownas iz flaan ovah MA Prawperdy, and iz lookin at my loveley teenage dawder!" and rabid slashdotters are at the ready to go apeshit about it - it might be handy to watch the drone owner's video of the tracking of the drone.

http://www.wdrb.com/story/2967...

At that height, I doubt the drone owner would be able to have seen the shooter's lovely teenage daughter. It was certainly interesting to see how the tracker folloed the drone as it lost altitude and crashed.

So I suspect in the end, I think the Shooter was just trying to prove his point and have something to talk about at the local bar. He'll be a legend to the terminally fearful, protecting hiz dawder from drowne flyin' preverts. At around 200 feet. I have a drone, and they just aren't designed to spy on people like that.

It's a good thing he didn't shoot down that pistol packin' drone we heard about the other day - that would have violated someone's second amendment rights, and started a 21st century Hatfield/McCoy war.

I'm not sure what sort of shot the accused used, but if it was your typical bird shot or target load, shooting into the air is hardly more dangerous than being outside when it's hailing. Very different from, say, firing a 9mm up in the air.

Those would probably not have taken down the drone, except by a very lucky hit.

US Navy ships have machine shops on-board, because they often need to fabricate objects while at sea.

Other than carriers and large support vessels however, the machine shops are generally pretty basic and operated by relatively unskilled/inexperienced people. (They're trained in the operation of the tools, but it's not their full time job.)

3D printing is a game changer even for the Navy in that it requires essentially no skill or significant training.

Britain Shuts Off 750,000 Streetlights With No Impact On Crime Or Crashes 307

Flash Modin writes: English cities are hard up for cash as the national government dolls out cuts. And in response, the country's councils — local governing bodies — have slashed costs by turning off an estimated 750,000 streetlights. Fans of the night sky and reduced energy usage are happy, but the move has also sparked a national debate. The Automobile Association claims six people have died as a direct result of dimming the lights. But a new study released Wednesday looked at 14 years of data from 63 local authorities across England and Wales and found that residents' chances of being attacked, robbed, or struck by a car were no worse on the darker streets.
