@cnh1995 , can you tell us what's going on with India's plans to raise the grid's highest transmission voltage to Megavolt range, in what phase of development are these things?

"The beam of magnetic field" is not good way of describing it. I guess you are asking if there is some way to make magnetic field to die away more slowly with distance from it's source? I'm affraid not much you can do in that respect. Possible are little improvements with changing the geometry...

Nevertheless, according to the source they had few exercises before: "Meanwhile, an official on the condition of anonymity said power demand may fall by 10 GW to 12 GW during the blackout, which will have no bearing on stability of the national power grid. The official further said this is not...

If you want to increase distance and still have a reasonable charging efficiency, you may want to try principles of resonance using magnetically coupled tuned circuits. About such principles you can read on this wiki page Don't know if anything of that is available on the market for cell phones...

What on Earth the pyramidal structure of the puzzle has to do with that sequence recursive relation?

The Load Rejection can cause potential problems. The consequences depend on many factors (grid interconnection structure, size of the grid, percentage of hydroelectric PPs in the grid, percentages of the rejected load with respect to max load capability of the network, type of load etc). If the...

I hope not...

DC source current is simply divided between wire and ground in proportion Rground/Rwire. In a well designed DC network this isn't an issue since allowed voltage drop is small and Rground>>Rwire. If local ground currents are sufficiently strong that may cause unwanted DC corrosion effects...

Total loses are difficult to calculate accurately for tiny motors. Only msms would give real picture. Here is the graph max efficiency vs motor size for small "BLDC" and classical brushed DC permanent magnet motors: Bellow m ≈ 1.3 g and output less than ≈1 W it is nearly impossible to attain...

Come on guys, Tesla invented or predicted all that :-p

They are if the scalling on the same type of motor is applied. The point is if you want to have more realistic simulation you need to know η(rpm) curve for a given motor. For smaller motors the influence of the small efficiency figures is bigger than for bigger motors. If you want to...

And hard disc motor efficiency is?

I don't understand why do you want to simulate electromotor powered by 1.5 V and less than 1W input. Do you know how low is the efficiency conversion of electrical input to mechanical output for a very small motor (even of brushless DC type) at high RPM? Very low. Much less than 50%

What was the purpose of your experiment? Small level of ionizing radiation can speed up the charge build up, but once the charge is collected, the build up almost completely stops in low fair weather conditions (charge depends on external field and size/elevation of the metalic structure). If...
