Notice it has cooling fins. That alone tells you it's wasting a good bit of energy

Controlling fan speed to only move enough air as needed is for sure going to save energy. Even closing the shutters is going to lessen the energy consumed by the fan. Put your hand over your vacuum cleaner hose and you will hear the motor speed up because you have taken the load off of it. Same goes with centrifugal pumps. Put an ammeter on one and shut off the valve on the discharge. The amperage draw will go down because now the pump is no longer doing "work"

Electricity is not some magical energy amplifier, all the conversions are a net loss of energy. It's called "entropy"

entropy 

A thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.

There is no escaping it. Whatever horsepower is required to run the fan to cool that engine, is going to be drawn from the crankshaft. Every step you add is a net energy loss. Belts are losses, alternators are losses, the wire is a loss, the electric motor is a loss. Introducing more steps into the energy flow makes things less efficient. Every one of those steps turns some of the energy to heat, and then it gets lost into the environment without doing work like turning the fan blades and moving air.

"The first law of thermodynamics states that energy is conserved and cannot be created or destroyed, only transferred or transformed from one form to another. The second law of thermodynamics states that in any natural process, the total entropy of an isolated system always increases. "

After a rain shower I noticed that I had a puddle of water on the floor.

That was always my problem with those things. Seemed like they always leaked when it rained. Lots of times they cracked the roof too. Maybe they weren't installed correctly

issue with the beer for me is the weight gain. last week or so for me attempting to meet a weight number before this up coming appointment ; NO beer/ eating healthy stuff. DR will kick my ass if I'm over weight. last saw him I was 200lbs (6ft) . today scaled in at 183.4 

Towards the end of my marriage in the late 90's I was stressed out and eating a lot, not to mention drinking tequila like it was water I got up to 360 and I'm 6' 3". Somehow I was still working like crazy climbing stuff, up on top of loads, rebuilding truck engines, doing clutches. I used to eat kielbasa and eggs for breakfast and wash it down with swigs of tequila and then go to work. I was running a steel nose 1974 DM with a roll off on it, no air conditioning, rough as hell looking, moving containers full of scrap metal all over Philly. I used to hit the scale at the scrap yard way overweight on 3 axles I remember sometimes over 100,000. I really don't know how I got away with it, or for that matter even lived through it.

After my divorce I stopped drinking and eating so much and lost about 100 pounds in about 2 years

Oh God. Please don't let there be an Obama Pope

And all those third world turds with degrees got them from places like Axact. None of the HR C^nts check up on that kind of stuff. They are all too lazy or afraid they might offend some non-white

Well, that happens to me all the time I’ve cut back considerably since I quit working, but I still go overboard occasionally without realizing it it sneaks up on you and yes, I’m sure you’re quite familiar with that

Yeah I wasn't as sick as the time I was drinking Everclear and orange juice and I woke up on the garage floor with my head in a cardboard box full of puke, but that time I was in my early 20's and I could bounce back better. BTW the reddish blonde was involved in that night, she was sleeping across the front seats of her CJ7 inside the garage. When she saw what I looked like she ran away.

So yeah I've been there

ive never had yukon jack,but i do like crown royal.....it doesnt have quite the big bite like the jack danials i usually drink.lol.bob

I haven't drank since my 40th birthday when the last thing I remember was talking to a chick with purple hair in a bar, and then waking up at my mother's house laying on the bathroom floor clutching a bottle of Nikolai Vodka that smelled like hand sanitizer, being sick as all hell, and thinking I'm too old for this crap. So I really don't remember what any of it tastes like. Well I remember the Nikolai Vodka tasted like lacquer thinner. Probably best I remember it that way

They only list a max Hp of 1.25 Hp for their fan motor.

I've pull heavy over the Big Horn mts, 3/4 of an hour wide open at less than 25MPH, Glad I had a mechanical fan drive and didn't find 1/2 way up that the electric couldn't cut it.

That is a hard test of any equipment.

There is just no way a 3 bladed fan can move the air of a 7 or 9 blade of the same diameter. Now most have a "ring" on the ends of the blades to prevent the air being thrown off the ends of the blades, and the hole shooting match is in a shroud to duct the air flow.

This is the place that he is talking about:

As I stated, no way I'd go down that road.

And going from mechanical to electrical, and then back to mechanical from electrical is two extra times entropy is going to rear it's ugly head

It's just adding more I2R and friction losses to the system;

If you go down the line of thinking that you can make energy appear out of nowhere, or make energy disappear, you end up believing in things Like Stan Myers "it runs on water" or this rediculas thing of Mr Yoon's

Yeah, the reddish blonde one has been a problem since I met her when she was dancing in The Nutcracker during Christmas of 1976. The brunette was my buddy's sister, Pictures are 1985ish

also if i was rich,,,i would have them all removed,,,,,last i heard they charge thousand bucks an inch to get rid of them,,,,and that figure was like 30 years ago

Wow, I didn't know that much

The electric fan thing is doomed to failure. You are talking about at least 25 HP to run a fan. The motor on that fan in the picture is nowhere near 25HP.

25hp x 746 watts / 24 volts = 777.083333333 amps. And that is not even allowing for losses. 

I'm sure the globalists were plotting and scheming for at least a decade before this happened

Thirty years ago last Friday, 17th June 1992, I went to Seattle to attend a two-day seminar by W. Edwards Deming. At the time I was the VP of Engineering at Compass Design Automation, meaning I was in charge of all product development. I just looked on Wikipedia and Deming was born in 1900, but in October, so he was 91 years old when he presented that two-day seminar. He would pass on in December the following year at 93. In the coffee and lunch breaks at the seminar, he was gracious enough to sign copies of his books. That's my copy of Out of the Crisis in the photo below, signed by Deming on 18th June, the second day of the seminar.

Until very late in his life, he was ignored and largely unknown in his native country, the United States, but he was worshiped as a hero in Japan. Indeed, the annual Deming Prize was established in Japan in 1951, over 40 years before I was at that seminar. It is awarded both to individuals for contributions to Total Quality Management (TQM) and companies that successfully implement TQM. Deming basically invented TQM. The prize is not restricted to Japanese individuals and companies. It has been won by companies such as Florida Power & Light (the first non-Japanese winner of the prize), Lucent (the first American manufacturer to win), Tata Steel, and Pentel ("a first for the stationery industry")

When I went to Allentown for training when V-MAC first went into production we used a laptop and the software used DOS commands.

I  spent a lot on that Bendix monochrome laptop with Windows 3.1 on it.

Yeah, it's like they have gone backwards. Fontella Bass was an an attractive and entertaining negress. They were doing well until LBJ's Economic Opportunity Act of 1964. In the late 50's and early 60's negro births had a slightly higher legitimacy rate than white births.

They try to run everything from the Midwest on a computer

Yeah they all want to sit in their cushy offices and never set foot in the plant. They rely on reports coming from the next level below them. And that level is just as stupid and not to mention are always lying to cover their ass.

There was another plant with a molding line that was all timed off of a line shaft that ran the whole line. Somebody got the bright idea that gearboxes on the line were old and should be replaced. The original gearboxes were like 39.5 to 1. Someone in upper management was told by someone that the originals were no longer made. So they had someone custom build gearboxes for the machine that were like 40 to 1. They thought that was close enough. They shut the line down for like a week. When they started it up, about 5 or 10 molds got squirted full of product, and then the product started missing the mold trays and squirting on the floor. They had to shut down for another week and install all the old gearboxes.

Two weeks production lost, the custom gearboxes were over $750,000 and God only knows how much in labor. And that was like 25 years ago.

So plant management hid the new gearboxes in the corner of a warehouse with a tarp over them and some stacks of pallets around them and act like the whole thing never happened. Like 3 years go by and some big shot from corporate comes to the plant and gets curious what's under that tarp in the warehouse. Now he wants to know what all the brand new gearboxes are there for. By that time the wrong ratio guy has retired. So he has my friend who was a maintenance supervisor investigate.

He already knew what had gone on and how the idiot above him tried to cover his own ass. Now he contacts the manufacturer of the molding line in Germany and when they get back to him they tell him the original gearboxes for that machine are still being made and they have some of them in stock.

It's only getting worse
