@dnyberg2, your question is fundamentally flawed. Using the bucket analogy again, if you have a 5 gallon bucket and a 1 GPM water source, you are asking if there exists any exotic high tech bucket that can be filled faster than 5 minutes. There answer is no, there cannot exist one even in...

Induction motors run at slightly less rpm than the synchronous speed. This is called slip and it depends on the load. We could guess a 5% to 10% slip for your motor. The synchronous speed depends on the AC frequency and the number of poles in the stator ##n_s=\frac{120f}{p}## rpm...

With the observation that @DrGreg has already answered this in #2, take a full stop here and analyze the conclusion in your last sentence. Why do you think your setup implies your conclusion, what implicit assumptions are you making without even realizing it, and how can you test experimentally...

@Crushforce, I think you just need one more NAND in the diagram from post 5 to invert the carry from bit 0, so you'll need 14 gates total for your 2-bit adder. But this is not a full 2-bit adder because it doesn't have a carry in, your bit 0 is a half adder, so you can't chain them to make an...

Gravitational acceleration does not affect clock rate, you said so yourself, it's the potential that causes the rate difference. This is also true in an accelerating rocket in the absence of gravity, the clock at the back is slower than the clock at the front even though the accelerations of the...

Have you understood A Lazy Shisno's example? I too prefer the scenario with a single flash of light originating in the middle of the train instead of Einstein's two flashes starting at the ends, but they are both equally valid and illustrate the exact same thing. In A Lazy Shisno's example...

For a Newtonian analysis draw ##\vec g## vectors on each ball pointing towards the center of the Earth. Now project those ##\vec g## vectors on the line of separation of the balls. Which way do the projections point? Does it matter if the car is going up or down?

Do you have an audio amplifier that you don't mind frying by accident? Hook up the waveform generator to the input and power the solenoids from the output. If it's stereo you can use both channels, one per solenoid. It also allows you to adjust the output with the volume knob.

Those gravitational waves arrived here a long long time ago. They were gradually increasing in amplitude and frequency as the binaries were getting closer together and were detected when they exceeded the sensitivity threshold of the instrument. There was no discrete arrival moment. The gamma...

Judging from the word "generator" in the title I think the OP is wondering about some method of extracting energy from sea water, not a (rechargeable) battery as an energy storage device. I'm pointing out to him that the energy in a galvanic cell is in the electrodes not in the electrolyte.

The salt water is not the source of energy in such a battery, it is just the electrolyte. The energy is stored in the electrode (anode) material. Take a magnesium rod and a graphite rod, stick them in salt water, or even in your back yard soil, hook up wires to them and you have a 1.8V battery...

Give these videos a try, they might have the answer you need. https://greatscottgadgets.com/sdr I watched them quite a while ago and found the concepts very well explained and easy to follow.

@HellRanger2558, apply for an internship at SpaceX and impress Elon Musk! :wink:

You need to know the heat capacity of the fluid, flow rate, inlet and outlet temperatures. This allows you to calculate how much heat is transferred to the fluid itself, the rest goes elsewhere. It gets more complicated if you have phase change (boiling) of the fluid.

While one can never say never, from what I've read about them they sound pretty much indestructible, designed to survive a rocket explosion during launch or crashing back to Earth from space. A space scientist or engineer can make that call. Another interesting advantage is that the probe could...
