It's basically a small capacitor. It does help with electric motors as they startup, however, the capacitor is so small it isn't going to help that much. It would probably pay for itself in 30 years or so.

 

Looks like someone's get rich quick scheme to me.

 

I was raised being told, if it looks to good to be true, it likely is.

Thats why i questioned it.

If its that easy to cut your electric bill in half, i wondered why everyone had not already done so.

 

Get those programmable thermostats that basically lower itself during the night ... since we are sleeping we dont know wtf is going on anyway lol

 

Excuse me if this is a duplicate -- I don't see my first one.

Anyway, places with large industrial motors need capacitors to correct their power factor. The inductive load causes a problem for both the consumer and the electric company. Thay's why they hang capacitor packages on power poles near industrial areas.

Should not really be a problem for the average home. If you have large enough electric motors to suspect that it's an issue, I'd still look elsewhere.

Their ad says rated for 65 kw. That's 65000 watts -- at 110 volts, it would mean almost 600 amps. Sure. Even if that's an error, the ad just doesn't ring true for me.

 

I smell BS. Here is the seller every time he cashes somebodies check;

 

They are selling those Hydrogen generator ripoff's for your car too. If anything that is a great page to keep track of all the scam's that are out there. I bet he has a resistor mod for your car on there somewhere too.

 

Sounds and looks like the "Tornado" for your car.

I'll bet that box is nothing more than an extension cord with the recepticle in said box.

"Uses NO power". (Because there's nothing in the box!)


I smell something. It smells like a rip-off.

Is Billy Mayes advertising this thing?

 

If you act now, We will throw in a double order of Sham wows and a free Snuggie!

 

I like how they say "Make payments of only $49.95" but they never tell you how many payments you have to make... 100?

 

Just start making them and I am sure they will contact you when you have made enough.

 

If you notice, it says "cut your electric bill in 1/2". Pair of snips can do that.

It does not say it actually saves you that much money or what % it will reduce your bill. It just promises a reduction. If it saves $5 a month, you would need 101 months/8+ years to recoup the investment.

Sounds like 90 days of scams and then *poof* he is gone.

 

Snake oil.

 

When I was a fresh engineer working my first job in an industrial factory, I had the job of installing a capacitor bank to correct the "power factor" for the operation. In industry, electricity is billed on the basis of "KVA" (kilo-volt-amps), not watts. Where I worked, we were billed on the average of the two lowest of the three highest "KVA" demands during the billing period.

Watts are usually considered to equal the system voltage times the amps (current) drawn. In a 3-phase distribution system used in industry, however, this isn't necessarily true because the high inductive load caused by many motors running simultaneously causes a "phase shift" between the voltage and current sine waves. This shift is called the "power factor", and is a number between zero and 1. The true power consumed is equal to the volts times amps times the "power factor". For example, at 100 volts and 5 amps, a "power factor" of .7 would only produce 350 watts of useable power, not 500 watts (100 times 5) as you'd normally believe. However, the power company still has to generate the 100 volts at 5 amps, and that's what they want to get paid for. Therefore, in this example, my measuring the KVA instead of watts you get (100 times 5)/1000 or 0.5KVA. The power company doesn't care that you're only getting 70% efficiency out of the electricity you're buying, just as long as they get paid for the total KVA. Theoretically, if the "power factor" went to zero, you could consume 100,000 volts at 1,000,000 amps and get absolutely no usable power out of it at all - but you'd sure have a large electric bill!

Capacitors are connected to the distribution system to push the "power factor" close to 1.0, thereby increasing the real power available for a given amount of KVA.

Power factor only figures into three phase systems. Since homes are single phase, adding a capacitor into the system would have absolutely no measurable bearing on the watt meter reading. Therefore, this device that's advertised here is similar to the magnet that's sold to be put around the gas line in a car or truck to "ionize" the gas and give better mileage. It's useless.

And FWIW, "power factor" doesn't exist in a DC system, like in your car. There, volts times amps truly does equal watts.
