Q:What is this bank account charge from STC travel entertainment?
Tell the bank that now that you have power of attorney, you have discovered a fraudulent charge on their account. See my source. You should probably close the account and open a new one for them.
Q:How to charge a flash capacitor bank?
A DC power supply that can deliver about 290 volts (NOT over 300 volts) will do that. A series power resistor based on the current output of the supply will limit the peak charging current to a safe value. For example, a voltage doubler from the 120 VAC line will deliver 330 volts DC. If you can find a transformer with a 200 volt 1 amp secondary, that will produce about 280 VDC. A 100 ohm power resistor in series will limit the current to 3 amps. Peak power in the resistor would be 1000 watts. Resistors in this capacity are very expensive. I'd try 3 120 volt 200 watt light bulbs in series instead. Under that setup, charge time will be: time constant is 100x10x0.16 160 seconds, and several time constants will get you charged up. EDIT, I'm taking your word on the caps size, and the above calculations reflect that. But I think they are actually 160µF, not 160mF. The latter would be much too large to fit in a cameral. Capacitor manufacturers tend to use m when they mean µ for some reason lost in history. In that case, the series resistor need only be a 500 ohm 50 watt unit and the charge time will be a few seconds. .
Q:What documents do the states get their powers from?
From the 10th Amendment and their own State Constitution. To regulate banking , all business and such for their own state without it stepping over or giving itself more power than the U.S. A.
Q:what kind of solar power?
You need to allow for the sun not to be shining all the time, so have enough battery backup to allow for this, depending on how much you will use the lamps. What voltage are the outdoor lamps? The best solution is to use car batteries and 12v bulbs, as these do not need an inverter (which do wear out). You can buy 12v CFL's quite easily. Then it's a matter of working out the load (wattage) of what you intend to run off the panels and buying about half as much again, to allow for the lack of sunlight, cloud cover etc.You'll also need a charge controller.
Q:Nuclear Power Plants Pros and Cons?
Pros Once constructed they operate virtually carbon neutral Very large amount of electricity from a small area of land (compared to wind and solar - even hydro floods massive amounts of land, just look at all the towns destroyed on the Yangtze River in China) Creates lots of jobs for the local population and beyond Warm (non-radioactive) water used for cooling the steam which runs the turbines is discharged to local waters sea or estuary (if located by a river cooling towers are used) encourages breeding of fish. Cons Risk of major accident: Very Low - Hazard from major accident: High (if it does go wrong, you'd know about it!) Has to be located far from large populations which increases power loss through having to transmit electricity via inefficient power cables Lack of knowledge by the public of the risks involved with site safety, environmental impact and dealing with waste can lead to unjustified and disproportional fear of nuclear power.
Q:Why are banks so greedy?
like hell their not greedy
Q:Does the fact that the Federal Reserve is owned by private banks and charges us to run the system bother you?
Yes it bothers me and it particularly bothers me that I am not allowed by law to use a competing, metal-backed currency which would actually hold its value independent of the federal reserve's self-serving inflation techniques. Several answers here have summed it up very well, so I only want to add a couple of things for anyone interested in this extremely important issue. First, something that has not changed in a thousand years, and never will:     Bankers have no loyalty except to money, and no nationality but Profit. Second, a prophetic quote from one of our first presidents: History records that money changers have used every form of abuse, intrigue, deceit, and violent means possible to maintain their control over governments by controlling money and its issuance.” — James Madison
Q:Example of concurrent power?
No, don't think so. The two are somewhat related and do meet at times but the relation is more complex
Q:How do I stick a power bank to the back of my phone?
Buy a cheap phone case then glue it to the back of that. Use a strong plastic glue and a hard plastic (not silicone) case. That way you can remove it from the phone easily and it will be strong enough to resist everyday use.
Q:Is it wise or stupid to save a lot of cash in your bank account?
Money in the bank will lose buying power. This is because the rate of inflation is greater than the rate of interest which banks pay. You may want to keep enough money in your bank account to carry you through a year in case you lose your job (if you're working. You didn't give your age.) Then speak to an investment broker about very stable investments and about money market funds. Money markets pay slightly more than bank accounts. However an investment broker's loyalty is first to himself, secondly to his employer, and thirdly to you. I suggest you get a book named Investing for Dummies, Third Edition [Paperback] by Eric Tyson. Please don't be offended by the name. For Dummies is a publishing company. Eric Tyson has written quite a number of books dealing with Finance. Google Eric Tyson. For Dummies contracts with authors who are experts in their field, and also have the ability to put information into plain English. This book won't make you an expert. However, it will give you the background to ask questions and understand the answers. I also suggest you google How to select an investment broker. Remember that the higher the financial reward the higher the risk. The lower the financial reward the lower the risk.
