No. It might move a swing, but that says nothing about space travel, where there is no rope or tensile force. The swing, and the tree that supports it, rotates with the Earth on its axis. How would the energy required for a propulsion system enter the sealed box?

It cannot be a "nuclear" EMP, but is can produce an EMP that interferes with radio reception. The atmospheric charge is stored in the electrostatic capacitance between separate parcels of air. Ionisation of the intermediate insulating air, increases the conductivity, which discharges the...

The limitation is on the thermal insulation that is required between each layer of Peltier junctions. You must build colder insulated spaces inside cooler insulated spaces, like those Russian dolls. https://en.wikipedia.org/wiki/Matryoshka_doll Even with perfect peripheral insulation, there is...

Then lightning could not occur as the atmosphere would discharge quickly at a low voltage. It takes a meteor to leave an ionisation trail sufficiently long to reach the ground. It does, and the UV from the first strike triggers the nearby parallel breakdown. The observed size possible in the...

Then the simulation model would be a four terminal, two winding transformer, oriented for common mode current. The primary and secondary in that mode are indistinguishable.

The trick is to delay all the minor strikes that will occur during a storm, until the last possible moment. The first UV flash will then trigger breakdown between the cloud and the ground over a large area. That makes it a parallel Marx current pulse generator...

That looks like an earth leakage detector or a common-mode choke. If the currents are equal and opposite, there will be no MMF due to the balanced circuit current.

Partition the problem. It needs a spark, air, fuel and a sense of timing. Starter motor. Does the engine turn at normal speed, and in the right direction? Fuel. Does the fuel cut solenoid operate? Is there an engine immobiliser? Is the fuel tank and pump full of water? How long was it...

Mobile phones usually have poor service in elevators. Are you saying it is recommended that you put your mobile phone in aircraft mode when you ride in an elevator, to prevent it from receiving a call, or trying to hand-shake with cell sites?

Their fear is probably real, but it is a paranoia, not based on reality. Their personal phones dominate their RF exposure. Maybe the residents just don't like the power company because they have to pay their bills, so they are going to punish the company by being obstructive. What legal...

Then the power provider should pay for and install the repeater. It will save them from needing to employ the meter readers. What has that got to do with the people who live on the floors above? You don't need the discussion.

Then they should throw out their mobile phones and Wi-Fi connections, because those affect them more running standard power close by, than the ones in the basement running at maximum power in an attempt to get through. That is not true, since it supposes wrongly that the meters could be...

How can they emit more RF than they should? More or less RF energy is irrelevant, as they are unable to transmit dangerous levels of RF. Who spends any time in the basement with the meters? What happens when 15 people get in a lift/elevator, with their 15 mobile phones. Do the phones all...

That diagram is misleading. The bar graphs do not show polarity. There is no reference ground marked. The red arrows, B, consistently point in the same direction as the current. But the polarity of B, will depend on whether the inductor is wound with a left-hand or a right-hand helix, and if...

The energy levels and frequencies involved, are no more of a hazard, than a handheld mobile phone, which is considered safe. A booster for the basement would also improve mobile phone coverage in the basement.
