Gas Prices Jump; California Hardest Hit
New submitter jefery23 writes with this excerpt from an Associated Press article (as carried by the Denver Post): "Californians woke up to a shock Friday as overnight gasoline prices jumped by as much as 20 cents a gallon in some areas, ending a week of soaring costs that saw some stations close and others charge record prices." Friday's jump followed another big one just a day earlier, too. Texas gas prices have gone up, but not quite so dramatically ($3.59 at the station nearest to me); how are they in your neck of the woods? Those Bloom boxes and charging stations can't arrive too soon.

When you have to lie to make a point, you should realize that your point is not worth making.

can't believe you pay what, $3.60 per gallon. jesus we had such prices 20 years ago. Calculating from litres to gallons,and from USD to EUR, they charge $8.64 a gallon here, in germany. everyone excluding me stop complaining;)
I live in California. We are paying the price for years of anti-business policies and nimbyism.
No, you're paying the price for turning the state into one big freeway. Gas in CA is more expensive because it uses a special formula, without which air in the state would be unbreathable.
Wow. You manage to bring in one thing to explain this thing and get it spectacularly wrong. As someone else pointed out, the Columbus Day weekend is the traditional ramp down time for refineries in the U.S. as they rejigger their formulation for fall (You didn't know refineries changed formulas for the season?). Also, several major supply routes got messed up:
From California gasoline prices soar amid refinery and pipeline shutdowns By The Associated Press:
As for Krugman and this being all the fault of QEx: there's a reason gas is not part of the core measure of inflation. Last I checked, we aren't in an inflation cycle yet. Gas is a volatile price (no-pun intended) that jumps way up and down responding to things like, you know, refineries having fires and pipeline shut downs. It's left out of most inflation conversations among economists.
Anyway, thanks for playing! Here's a home version of the game "The Eeeevil Fed Is Coming For Your Savings!!"

Right now it's a comparison of industrial strength electric motors with consumer gas engines. As the electric car will become more popular, the same trade-offs will be made (weight, durability, price) as for consumer gas engines.
Umm, what? Lets take this whole thing point by point. You're clearly suffering from a lack of actual knowledge. Let me help you with that. To put this in perspective, I work for an industrial transportation company. We have a large commercial fleet of vehicles, some of them EVs, most conventional. We also have a large warehousing and freight forwarding operation which makes use of vast quantities of industrial electric motors. So, we can be described as having a pretty good perspective on all of the various technologies involved, as well as what would be described as expert knowledge of the operational profiles of the most industrial equipment available.
Window wiper motors, window motors, fan motors all die multiple times before the engine fails. Most cars are wrecked with a capable engine. Most engines are not economic viable once difficult-to-reach seals need be replaced. Nevertheless, gasoline engines have a huge tolerance for maluse and neglect (excessive play, valve problems, etc.), electric tends to be more of the ON/OFF type.
Without regular maintenance (weekly oil and water, Three month PMI, yearly state inspection and daily pre-trip inspection of our vehicles, they would quickly become dangerously non-functional. Engine problems are the usual trouble and engine failure is frequent enough that our vehicle specifications require easy engine replacement procedures compared to passenger vehicles. We typically go through 2 to three engines in a vehicles operational life of fifteen years. Typical mileage on the vehicles at retirement is between 300k and 600k miles. 400k is considered quite good for one of our engines (They are rated for 10,000 hours or 300k miles). By contrast, most of our vehicles are taken out of service with the original wiper motors, fan motors (only a small percentage of the fleet has electric fan motors) or water pumps. Even more telling, we can use the stats for the belt drive motors in use in our local warehousing facility. The drives are rated at 18kW continuous with peak load handling of 30kW for 10 seconds. We have around seventy five of them in our warehouse. I have been stationed in this building for ten years, and in that time, we have had one drive motor fail after a new variable speed controller was installed wrong and overloaded the motor (and itself). The MTBF on our motors from the manufacturer are 100,000 hours continuous operation, and 75,000 hours for 50% rapid duty cycle operation, but in our operation we have many motors that are well past the 200,000 mark, and none that have failed in service. The manufacturers don't even list MTBF information because its pretty meaningless. I had to go digging to even find Baldors specs on it, and they have a disclaimer that they really don't know what the expected life span is because almost all of their motors are decommissioned long before they fail. Whenever you hear about motor failures, its always because they're being overloaded / pushed beyond spec.
When both applications are compared in the same industrial environment, large freighters, heavy machinery, I've seen electrical (sub)engines always need be replaced multiple times, under far less demanding conditions. wartsila.
Yeah, whatever. Making electric motors last is a matter of correctly sizing the motor for the application. If you're constantly frying motors, its because you used a motor that is not large enough for the application. Going to the next size up will fix most of that problem for you. A sufficiently sized and maintained electric motor can and will last decades. We have several 275kW Baldors in our building that have been in service since the 50's. They are never run past 25% capacity which keeps them nice and cool. B
