### Re: 700 mile charge in 1 minute

punxor has the same numbers I got with my calculations. I sometimes take a full 4.1v battery and connect it to a 3.0v battery to get it up to chargable voltage and the wire connection gets warm in a hurry. I'm a retired power company lineman, among other types of employment and have had huge plasma ...

### Re: 700 mile charge in 1 minute

I took a stab at calculating the battery pack needed for 700 miles, then figured 450 Whrs/mile and my calculator went blank. Have to figure what voltage and amperage before calculating, then figure in 1 minute charge ?? I just don't see it happening.

### Re: 24V/48V UPS as an inverter for mini power-wall

Ok then. In the link I provided, the guy took 2 SMART APC UPS's, which are true sine wave not modified square wave, and they were not equal output. One was 950 W and the other 1500W if I remember correctly. Been watching videos quite a bit lately, because wife and I are both under the weather. He us...

At hillhater Yes you have to sync the 2 inverter sine waves.

### Re: 24V/48V UPS as an inverter for mini power-wall

I have 2 of the older 24v 1400 Kva SMART APC UPS's. They put out a true sine wave. I believe I can parallel them to get twice the amp capacity and add computer fans and use them as my inverter for my partial off grid system with Chevy Volt modules. You tube has some really smart people that show how...

### Boost 110v AC to 120v AC or slightly more

The power company down here keeps the voltage on the house side to around 108-112v. I keep after them to boost it up to 120v or so, where it should be. As long as I am the only one complaining, they just ignore me. As anyone with AC voltage knows, 108-112 is extremely low. In my shop when I try to u...

### Re: Rubber cushion drive in rear motorcycle wheel

I think I would look at it the other way around. Is there anything to be gained by removing it?
Yes, there are 5 of the fingers to be removed, and, no way to attach it to a flat disc to bolt it to the wheel. I also reduce nearly 1.5 inches of width so it all fits in the swingarm.

### Re: Rubber cushion drive in rear motorcycle wheel

This will be a toothed belt similar but more stout than a timing belt. No shifting under load and a 3 to 1 ratio for less stress at takeoff.

Will wait for a few more comments and appreciate those already posted.

Thanks guys.

Dauntless, he stated it was a 1981 auto and he posted under alt energy section. According to my search, it's a 50A alternator.

OEM wants to build stuff as cheap as possible.

### Re: Using an old car alternator to generate electricity...

Don't know if you are capable, but, if you take the alternator apart and carefully/forcefully separate the 2 halves of fingers/claws on the rotor, you can remove that field coil inside and replace it with 2 ring magnets and press it back together. Then you don't need the brushes that will eventually...

Ever think about a front bumper mounted ball hitch ? Heavy angle bolted through the bumper and mount the ball. That way, you can SEE what you are doing, and get quick response on turning.

In that warm climate, if you don't debark those logs and get them off the ground, you will have scrap logs within 2 years. IF you happen to get to sawing them, keep an eye out for the " Denim Pine". It will be blue stained and sell for more than regular pine.
