Texas Power Rolling Outages

It will start to freeze in 49 minutes

Actually there’s a serous flaw in the setup. Can you find it?

Good question. My formal electronics training didn’t go much past Ohm’s Law, but the following initially stood out:

  • One usually sees an alternator in these setups; I believe that in order to provide current the motor would have to be of the permanent magnet variety
  • The use of a diode on the battery cable suggests AC current, which is apt to be a tad inefficient charging a battery. And one might want a diode on both leads?

But a little googling shows that the MY1016 is a 24V DC motor, which is apt to make a typical 12V SLA unhappy. Powerbright inverters can be had in 12C and 14V flavours. You could drop to ~12V with enough diodes inline but that’s also inefficient.

The diode is to keep the battery from running the motor as a motor. And a 24 volt motor will put out 14-15 volts for charging at a likely more reasonable RPM than a 12 volt motor will. In fact, the battery will pretty much limit output voltage, and extra effort above the RPM required for the current battery voltage plus diode voltage will have more effect on charging current than voltage.

All that along with you have an unregulated voltage going to the battery. That battery is going to become very unhappy/short lived. Gel cell will tolerate some of this. Lithium - all bets are off.

Possible better set up. Replace batt w/ cap. Connect to buck-boost regulator. Set output to run batt charger ckt. Connect to batt and run the world.

Interesting fact - 1 hp ~= 750 watts. Your average bike pedaler ain’t gonna come close.

Trip through the way back machine. Family vacation to Chicago. One of the museums had a bike set up w/ generator. Was connected to 100 watt light bulb. The incandescent kind. Managed to get the bulb to light up, but not for very long. Don’t think they were to worried about someone burning out the bulb.

It is no secret the Russians and Chinese have been working on antisat capability. Add to that they have their own “GPS” network and it is clear what they want to do…

Just like cell phone jammers, gps spoofing/jammers are available. We’ll learn how to spoof/jam those new system. And if we’re smart, we’ll learn how to use those new systems. Learning old school methods is a good backup.

The US has the GPS System,
The Russians have the GLONASS System,
The Europeans have the GALLIEO System,
The Chinese have the BEIDOU System,
and the Japanese have the QZSS System.

Most of the GPS Receiver chips out there are programmed to read any of these satellites. But, then again…all it takes is for a country during war time to simply upload a different set of firmware to their specific satellites, then all bets are off.

Lol, Thankfully I know how to read a paper map.

Check out the real story at U.S. Navy Brings Back Navigation By The Stars For Officers. A very chilling story that also talks about the Russians and Chinese.

Yeah, I prefer hardcopy road map over the nav system in the car. Use the nav system as a backup to the map. Works good when you have daylight to spot landmarks etc. Navigating an unknown area in the dark gets interesting very fast. Things get more interesting when there’s no landmarks matching your map.

Wonder if they’ll update this book -

Looking forward to an article on this massive failure in IEEE Spectrum.

Then there was selective availability.

Supposedly, it will not be used in the future, but can you blame potential foes for not believing?

I used to partake in the “all you can eat” maps benefit at the auto club for road trips.

In 2012, I relied totally on GPS navigation for the first time due to traffic problems. It was an interesting experience especially following the actual route on physical maps later that night.

There are periodic reports of GPS nav directing drivers onto railroad tracks or impassible unpaved roads.

Like all technology, it is good to know how to do it manually.

Isn’t that basically what differential GPS was? A built-in small error that could be corrected for if you knew the current secret? That error could be made large.

Some guy just spent a week stranded in the mountains because his GPS took him up a random unplowed back road.

Just as valid today…

Human food generation uses a ton of power to get to your mouth, then heat losses in digestion before it becomes ATP from fats. Then heat losses with muscle contraction. Our food to energy losses are about as bad as a gasoline engine. I prefer solar.

This doesn’t seem like a new problem :slight_smile:
