Ocasio-Cortez comes alive

AOC showed up to speak at Astoria Park to boost the Green New Deal during a protest against the proposed power plant coming to Astoria.

Sorry for the shakes but the audio's alright.

Ocasio's 14th CD only, starts right under the Hellgate Bridge and runs northward at the top end of the park. That's right folks - the physical division between Maloney' and Ocasio's districts runs right through the park. Maloney has the vastly greater physical share.

Even if you covered that whole sight inch to inch in the best high output solar cells, you would only get around 2 megawatts. --Enough power to run perhaps a single small 6 car subway train or a school and a couple homes during the daytime. The problem is our utility's, TVs, ACs, HVAC, Computers are still to inefficient running on the same 60Hz 110 VAC as 100 years ago and that's were the focus should be.
Not one school, college or energy company will tell you this.

The greenest way to benefit such a dense population with towers is perhaps a small nuclear plant or cover all of Roosevelt island in solar panel's.
When it comes to city's, green energy, free energy are myths like Loch Ness monsters, RooGarux, ChupaCabra's . You cant change ohms law or the laws of physics.
Example 1 volt into 1 ohm=1 watt, and you cant get 20,000 BTUs of AC or heating out of 1 watt, You need more like 1000 watts, which is four high grade 250 watt solar panels full sunlight taking up a 12X15 foot print. And that doesn't include the losses in inverters and voltage regulation to turn DC into stable 120VAC 60Hz sinewave

Sorry pal. but computers INTERNALLLY use +5/+12 Volts in general, CPUs, memory 1.35-1.45 Volts.

The PSU in your system is the most IMPORTANT piece, good quality, stable power needs to be delivered from 110/220 Volts - not an efficiency issue since ALL COMPONENTS work at low voltages.; Monday, April 26, 2021
Gino said...: Some genius writes: (Sorry pal. but computers INTERNALLLY use +5/+12 Volts in general, CPUs, memory 1.35-1.45 Volts)

LOL--Another jackass, or is this MIT graduate AOC herself ?
Internal or external 100 feet away how do you think all those different DC voltages are derived from 120 AC home electric and derived isolated from the AC bus (BLACK or RED) at that ?
Clue--Not one of AOCs college professors or the same place Jack got his beanstalk beans that's for sure!!

Answer:
(With exception of boats, aircraft, Space satellites running directly off 12, 24 VDC which is then direct regulated down.
95% of computers use switching supply's where
120 VAC line voltage is rectified and filtered into 160 volts DC.
(You get 160 DC from the peaks in the AC sinewave)
This now 160 DC voltage is then chopped into high frequency AC Squarewave through a switching transistor(yes back to AC again) to drive a transformer with several different windings to give you secondary's windings & taps for 1.35-1.45,3.3/ +5/+12.
The transformer also provides Isolation from the 120VAC mains to meet UL safety codes.
Each one of those now isolated low voltage windings must then be rectified & filtered back to DC a second time where its then passed through regulators and current limiting. Now add a fan sucking 300-500MA to keep all the crap cool--And that's just the power supply fan!!
Even with the best MOSFET transistors, Schottky diodes, low ESR capacitors computer power supply's are no better then inverters that incur 20% or more insertion loss.
Switching power supply's are actually the worst with huge losses through all this AC-DC-AC-DC conversion and regulation.

Anonymous: Go sit in a corner till you know what your talking about, stop listening to AOC, Bidon, your idiot teachers, college professors and all the other clueless dumb fucks feeding and repeating horseshit another dumb fuck told them. I assure you nobody in that chain is a real hand on electrical or electronic engineer.

80 Plus rating means anything to you?

For your information at 20%-50%-100% is at least 80% efficient.
An 80 Plus Titanium (the highest rating) is between 90%-94% efficient.
Most power supplies on the market today are at least 80 Plus rated for a very good reason.

"Now add a fan sucking 300-500MA to keep all the crap cool--And that's just the power supply fan!! "

Most new power supplies don't even have a fan or it can be turned off.

"This now 160 DC voltage is then chopped into high frequency AC Squarewave through a switching transistor(yes back to AC again) to drive a transformer with several different windings to give you secondary's windings & taps for 1.35-1.45,3.3/ +5/+12."

Wrong!
Transformers are used to step down the voltage to a primary 12V line and a secondary 5V line. The main 12V line is then stepped down further using DC-to-DC converters to 5V and 3.3V for the PC to use. A secondary 5V line is used to supply the 5V standby power circuitry so that the computer can turn on from the front power switch.
Since only 12V is created from the main transformer, DC-to-DC converters are used to create the 5V and 3.3V.

The quality of the power is the most important! VRMs anyone?

HEAT! You can run an OVERCLOCKED CPU very efficiently today, thanks to AI in the modern power supplies with simple air cooling via CPU fan.

Hardcore overclockers use liquid cooling, has nothing to do with the efficiency of the power supply - the chips need to be kept cool. Goes for video GPU, CPU.; Tuesday, April 27, 2021

Your still going through the initial switching lossy transformer, rectifiers, filtering to create that high amperage 12V DC line you idiot. (What I said in the first place).
80 Plus rating (ER) is not good enough, it also depends on how the product is used
2:No home computer or TV & LED backlit screen should be using over 60 watts at 100% CPU and video usage let alone 300 or more efficiency!

You can buy any energy rating sticker you want here, stop listening to the government and Department of Energy's Energy STAR program making these study's and ratings which are all fluff in most cases.
The corporations selling the shit and Chinese assembling have them all the pockets.

Anonymous said...: Gino you need to relax, obviously you don't know much about computers or the power supplies in them. Your knowledge is a bit dated.
Trying to balance you lack of knowledge with AOC and snide remarks, but makes no difference.

Switching:
Switching clumps a few actions together to achieve the same effect, allow electricity to flow through to the rest of the power supply. Other functions of switching include
protection circuitry, such as overvoltage, overcurrent, overpower, and short circuit protections.
Provide basic feedback to the computer, the most important one being the power good signal, which tells the motherboard that the PSU is good to go.
Create a high-frequency (in the tens of kilohertz range) AC output. The reason is that this allows the transformers used in the next step to be small.
Switching requires feedback from the output in order to work properly. This is done by tapping into the output voltages that feed into the computer.

Got it?

***2:No home computer or TV & LED backlit screen should be using over 60 watts at 100% CPU and video usage let alone 300 or more efficiency!*****

60 Watts at 100% CPU? Dude you really have no clue what you are talking about.

Ok, AMD has 65W models, but mostly 105W models. Intel has a lot 125W plus models.
Regardless, the video cards use most of the power anyway. Like an RTX, BigNavi.

Power consumption on the LED screens is size dependent in the same technology branch! OLED, IPS, LCD aren't exactly the same you know.

80Plus is the minimum and is very good at being efficient!
Don't believe me? Don't have to. Check you Con Edison bill.

Not sure what your background is, but is not computing that's for sure!

Here is the power draw per average components:

Low/Mid-range graphics (like GTX 1660) ~165-200W
High-end graphics (like RTX 3080) ~350W
Mechanical Hard drives ~9W each
Solid State Hard Drives ~3W each
Intel/AMD Consumer CPU (i5-10600 or Ryzen 5 5600X) ~75-125W
Intel/AMD Pro CPU (Intel Xeon or AMD Threadripper) ~140-200W+
Motherboard ~30-80W
RAM ~3W per stick
Optical Drives ~25W

Not to sure about that, and I think he's Sicilian. Anyway the game playing trolls are admitting they are consuming huge electric. Those lines "As a hardcore gamer" and that list of "power draw per average components" says it all, including stupidity.
These guys are just cutting and pasting specks and clearly ignorant in electronics & electrical engineering. Todays version of kids building Mopar gas guzzling hotrods, Bradley kit cars & buggys from prebuilt motors, frames and parts back in the good days. I also remember the gas lines and shitstorm you got if you badmouthed one of those cars for any reason.
Advance to 2021 with a twist:
Now its young shithead gamers out in full force in defense of wasting huge electricity to playing games on rodded cranked to the max computers yet complain "we want free or cheap green energy to power our 800 watt gaming computers"
Holy Shit, What a huge oxymoron written by actual morons.
Typical Millennials, Shit brains and Bidet-a-boo's !!
If they are going to do this crap they should do as AOC says "conserve" and use laptops or phones till actual advances in desktop technology gets the power usage down.
That list of "power draw usage per average components" is absolutely obscene and disgusting, it pretty much says what Gino was complaining about.
As much power (or more) then a midsize bedroom window air conditioner to play video games? Cell phones have the horsepower to play those games on battery power for days. Elon Musk has satellites beaming internet to millions from space on the power usage of a laptop. All these desktops "gas guzzlers" in near every home running 365 a year are at best, still just that "gas guzzlers" consuming a huge piece of the pie making green energy's near impossible to feed.

Check Wikipedia about it while you checking PSU operations.

Cryptocurrency mining is done mostly via specialized hardware, not PC-s.

Gino said...: Knuckleheads -- 160DC is the rectified and filtered 120AC, its across the primary electrolytic in the power supply after the line chokes and diodes.
If the in from the wall outlet is 120VAC it will be 169.70 to be exact after rectification and the primary filter capacitor.
Its called VRMS
Wall AC is a 120 volt AC sign wave (Volts RMS)
The full voltage between positive and negative peaks of the waveform go through the rectifier diodes then into the primary capacitor. This is, the sum of the magnitude of the positive and negative peaks of the 120VAC sinewave.
This magnitude of the positive and negative peaks is called Vpp (Volts Peak to Peak)

Anyway you gamers and tinkers are so upset you are completely missing the point.
Which was desktops in homes use too much electricity.

Yes, wall 120V wall AC becomes 160-170 volts DC when its converted to through a full wave bridge rectifier and filtered into DC.
The capacitor fills in the ripple voltage it then heads to the switching stage.

The power supply is designed isolated so you never would.
To find that 160 DC you would need to open up the PSU, get to the primary side of the board and line transformer. Its across one of the large 250 volt or more electrolytic filter capacitors. (the low output side has the 1000uf or more 16V and 25 Volt caps)
The PSU would also need to be plugged in with the board slid out with your test leads on the trace side. (some better PSUs have test points, sometimes you can access this measurement off a diode or power transistor from the topside)
I talked to computer repair guys, they don't do time consuming bench tech component level troubleshooting & repairs on anything that needs desoldering.
They are trained to just replace the whole PSU, boards, cards, etc and move on.

PS: I learned by figuring out and fixing computers people threw to the curb as a hobby with a little help from a friend Jimmy H who worked at the IT dept at Bank of America downtown.
He would come over and see me desoldering capacitors on a PC board and laugh "smoke, are you kidding me, throw it out and replace it with a new one" Response: "But, Jimmy I don't have a replacement or new one, I got to fix this to use the computer" Unfortunately Jimmy passed around 10 years ago.

Gino said...: Easy Kato, you don't need all that math and formulas.
You take your 120 wall AC and multiply it x 1.41
That's your peak voltage the filter capacitor develops and holds after rectification (around 168/170 no load)
That's the formula for sinewaves RMS to Peak to Peak without all the bullshit.
I try to keep it simple so readers here can understand it an learn.
Don't they teach you anything in school, or did tech schools and the UFT toss physics and ohms law out the window also? Its a common issue, most these computer repair people and gamers don't know crap. They complete repairs by swapping out boards and power supply's, not actual electronic component level troubleshooting bench work that takes time, special skills, equipment and effort.
Its become a lost skill and dam shame at that.

Actually I'm a licensed electrician, plumber and contractor.

NOPE WRONG !
Look closely, not even on the power switch which accesses TTL controls that allows the PC to turn on, sleep, wake up, wake up on LAN etc.
