Hurricane Maria Knocks Out Power To Entire Island of Puerto Rico (cnn.com)
An anonymous reader writes: Hurricane Maria's eye has left Puerto Rico, but the mammoth storm is still lashing the island with devastating winds. Maria weakened to a Category 3 hurricane Wednesday afternoon, hurling winds of 115 mph. But hurricane-force gusts topping 74 mph still extend over much of Puerto Rico, the National Hurricane Center said. Maria's brute force wiped out electricity to the entire island. "We are 100% without power," a spokesman for the Puerto Rico governor's office said Wednesday. The storm also ripped trees out of the ground and caused widespread flooding. "This is total devastation," said Carlos Mercader, a spokesman for Puerto Rico's governor. "Puerto Rico, in terms of the infrastructure, will not be the same. ... This is something of historic proportions." Maria is expected to dump a total of 12 to 18 inches of rain on Puerto Rico before barreling toward the Dominican Republic starting Wednesday night.
The cat3 hurricane ENGULFED THE ENTIRE ISLAND.
Real news would've been all the power staying on!
"We are 100% without power," a spokesman for the Puerto Rico governor's office said Wednesday.

What a horrible stroke of luck. Hopefully we can gather important data from this disaster, and potentially improve upon our infrastructure.
Got family there, and they went out of communication around 4am. Pictures coming out from their city show some massive destruction, which looks pretty widespread across the island. It's going to take a long time for them to recover from this.
San Juan still didn't have power in parts due to Irma when this one hit. I wonder how long it's going to take to restore power after this. Months, at least.

In 155 MPH winds? Why am I not surprised?
Actually, the issue will be power transmission lines.... Not generation capacity, unless they got really unlucky...

Puerto Rico only has electricity because racist white men put it there.
It is now reverting to its holy unblemished natural state.
shakng, sinking, & being shot at all over the world again today.. better days ahead.. guaranteed
Anyone with a modern 2010 or later house built to hurricane standards and a Tesla solar roof and Tesla storage batteries, by definition, has full power.
I think you meant to say "grid electricity to Puerto Rico will be offline for 4-6 months".
Even people with wind power could have taken the wind turbine housing inside during the storm and put it back up after it passed. It's a fairly simple operation.
Same goes for generators - you take it inside a secure location built to hurricane standards until after it passes and then move it outside.
Does nobody on this site understand modern energy production?

You just have to take the turbine blade off during the storm. It takes a few minutes, you put it inside a secure 2nd floor closet, and you put it back up once the storm has passed. I used to do that all the time. Are we seriously saying people are so stupid they don't take basic off-line power actions?

Please remember that Puerto Rico is our responsibility. This something we need to be talking about.

A lot of Puerto Rico's electrical network is badly neglected. Much of the system is suspended on old fashioned post-war power poles and overloaded with too many cables. It looks like something from 19th century New York. None of this is terribly surprising: it's a government run power system that is absurdly dysfunctional.
The whole thing fell over. Big surprise. Not.
Maw! Fire up the karma burner!
If you have family members in Puerto Rico and want to do them the greatest favor possible, buy them a 3000-3600 watt inverter-type generator, four 5-gallon gas cans (empty, of course), and one or two Carbon Monoxide detectors (or smoke alarms with CO detection built in), then FedEx (NOT UPS) it to them tomorrow so they'll get it by Monday.
Why 3000-3600 watts? Big enough to start the air conditioner & refrigerator, with enough spare capacity to throttle it down to half-speed to keep them both running overnight. Trust me... if the climate in Puerto Rico is anything like the climate in Miami, air conditioning isn't a luxury, it's life-support.
3000 watts is also big enough to run a second window a/c unit or a washing machine (tip: don't use the dryer... even if your generator is big enough, dryers cause large amounts of outside air to get sucked into the house... including outside air with lots of carbon monoxide from the generator sitting 10 feet away from the door or window that's cracked open so you can feed the extension cords through it.)
Why inverter-type? Fuel efficiency. They're going to be using it for a few weeks, minimum. A traditional 10hp 4800-5600 watt generator burns through about 15-25 gallons of gas PER DAY. It's kind of like comparing a 1970 Cadillac Eldorado to a Toyota Prius. An inverter generator will literally pay for itself in gas savings after 2-3 weeks. Post-Irma, I spent more than $250 to keep my old generator running until the power was finally restored a week later... and THAT was with 4-8 hours/day of non-usage. They're also a LOT quieter than conventional generators, especially when running in "Eco" mode. Imagine trying to sleep over the noise of a typical window a/c AND two lawnmowers running in the back yard... that's what it's like trying to sleep with a traditional generator.
Why gas cans? Gas cans are utterly IMPOSSIBLE to buy for at least a few weeks after a major hurricane. With an inverter generator, four 5-gallon cans should be enough to let them get away with going to the gas station every other day. Five or six are even better, but I was BLOWN AWAY last week when I saw how expensive gas cans are now (I paid $10/can post-Wilma and felt ripped off... now, they're more like $25-30 apiece AND have shitty new safety spouts that turn refueling into a 10+ minute exercise... if you have any old gas cans, treat their spouts like gold).
Why the carbon monoxide detectors? Safety. Carbon monoxide can easily get into the house, and the fumes WON'T wake them up if they're asleep. Put one detector near the door/window that's open for the extension cords, and another next to wherever people are sleeping.
Another tip to share with them: a typical American electric water heater (one or two coils, 240v, approx. 4500 watts) can be powered with 120v from a generator without problems. It'll draw 1/4th the total wattage (ie, around 1100 watts at 120v) and take longer to heat up the water, but it definitely works. Wire it up as follows: generator 120v "hot" to water heater's "240v hot #1". generator's "neutral" to water heater's "240v hot #2". generator's ground to water heater's chassis ground. Try to use an extension cord with at least AWG14 wire or better... AWG16 will work in a pinch, but you'll end up wasting 10-20% of your wattage heating up the extension cord instead of the water.
Other nice features for the generator to have: bluetooth or wifi so you can check remaining fuel/runtime and current power draw using your phone or tablet. Push-button starting (esp. if someone who's not very strong has to start it).
A generator able to sustain 1800W and surge to 2500W might be OK, but inverter-type generators in THAT range tend to have absurdly small gas tanks. Trust me... getting up in the middle of the night to refuel really, REALLY sucks. Especially when it's 89 degrees and 80% humidity outside.
Typical current draws I noted after Irma:
6000 BTU air conditioner: 5A, 550 watts
8000 BTU air conditioner: 8A, 900 watts

My thoughts and best wishes go out to the people of Puerto Rico, the Virgin Islands, and others devastated by hurricanes. I can't imagine the destruction and chaos this has caused.
Way ahead of you soj51 dot org
Of course, the most likely way it becomes reality is if California secedes.
... the hurricane is damaging Puerto Rico almost as much as the treatment it gets from the federal government.
(whoosh)
Shut the fuck up will. You are a fucking idiot. Yea let's take a wind turbine and store it on the second floor. Fucking idiot.
Almost back to a pre-Columbian era. And looks what happened to them. Stay safe, PR.

There is no possibility that Fedex nor any other shipping service will have restored operations that quickly. They certainly didn't in Florida after Irma.
A friend with family in Puerto Rico contacted three family members living in three different cities after this quote became public and all had power. Perhaps they rounded to the nearest 100%. That isn't to say it isn't bad. After having just spent eight days without power due to Irma, I feel for them.
UPS, I totally agree, is fucked and hopeless. They probably won't even acknowledge the location of packages already in transit until the end of next week. They suck.
FedEx might be do-able early next week if the package were held for pickup at their main facility in San Juan.
Ditto for 3-day Priority Mail. According to USPS.gov, a 55-pound box measuring 22x22x20 would cost around $90 to mail and arrive on Monday, 9/25 (with caveat that their air freight capacity is limited & might sell out at any time)
The only catch is that a 3200-watt generator would probably weigh too much to send via air, so you'd probably have to settle for a 1800-2200 running watt (2500-3000 starting watt) generator.
There's actually another nifty fact I discovered last week: contrary to the official instructions that come with most inverter generators, you don't HAVE to use the manufacturer's official parallel cable, nor do you have to use two identical generators.
Most parallel-capable inverter generators will sync up to ANY source of live voltage they see, regardless of source. You can even use a DC-AC inverter to add a few hundred watts of surge capacity to the generator (say, if your generator is big enough to RUN your air conditioner, but not quite big enough to START the air conditioner without a little extra help).
All you need is a homemade "Y" cable (take two outdoor extension cords, cut off the plugs and receptacles leaving 18-24 inches of cord, then splice the wires from the two plugs onto the receptacle). The main thing you'll lose by making your own hacked cable instead of using the official one (with banana plugs) is passive safety... the official cables are designed so that if someone pulls the cable out from one of the generators, the live voltage will still be at least somewhat shrouded against accidental contact. If someone yanks out one of the plugs on a homemade cable, the pins on the plug will be carrying live voltage. Electrically, though, they're the same as far as the generator is concerned. Behind the plastic panel, those banana plug lugs are wired directly to their corresponding prongs in the receptacle.
Just to add... if you hack your own parallel cable, you can also do something like pair a cheap $109 800W Harbor Freight generator with a more expensive 1800-2200 watt inverter generator. Just connect the homemade Y cable to both generators, start up the Harbor Freight generator first, then start up the inverter generator second... it'll see the voltage from the Harbor Freight generator and sync up to it. Once you've gotten everything that needs lots of surge power started up, you can turn off the Harbor Freight generator and leave the inverter generator running.
The winds are stronger at turbine height due to less friction. You'd never run a turbine in a hurricane because you'd destroy it. That's why there are mechanisms to prevent turbines from operating if the winds are too strong.
Puerto Rico is actually a lousy place for wind power, anyway, just like most of the tropics. The wind is driven by differences in temperature, which cause differences in pressure. There isn't much of a temperature gradient in the tropics, so the winds are generally weak relative to higher latitudes. Puerto Rico is, however, a pretty good place for solar power. The cloud cover is low enough and the sunlight is pretty direct at the low latitude that solar power works pretty well there.
... Do you know how big the blades are for turbines on this scale?
"So long and thanks for all the fish."
Are we seriously saying people are so stupid they don't take basic off-line power actions?
Well, I've seen them put up and take down a wind turbine on Alaskan Bush People, so yes. Definitely yes.
Most mobile turbine blades come off. They're not very large, and they fold up for storage. In fact, that's how they ship them.
Most residential wind power has blades about the size of your arm. You can literally put it on the corner of your upstairs deck.
You're thinking industrial wind turbines.
"... on this scale." Yes, I'm thinking industrial. The smaller ones are pretty much useless for whole house power. Residential wind turbines don't really make a whole lot of sense for most people, certainly not in the tropics.
"So long and thanks for all the fish."
Username checks out.
Residential wind turbines don't really make a whole lot of sense for most people, certainly not in the tropics.
They make a great deal of sense. Emergency power in a compact unit, that isn't even as fragile as solar panels, let alone as bulky?
You can be sure, a lot of people would LOVE to have even a 100-watt wind turbine now.
A thousand-watt unit that can keep medicine cool, light some bulbs, even boil small amounts of water? Get me one now.
It's all about the application, KGIII, all about the application.
