Researchers team up with architects to create bladeless wind electricity generator It takes advantage of wind moving over the inner grid—positively charged water particles are carried (via spraying) away from the small inner tube mesh, leaving negatively charged particles behind. That causes a decrease in the voltage of the system and allows for ...

You can implement your Kelvin air-dropper or air-squirter if you can ionize the gases, first. Radioactivity can ionize the gases as they exit the first rings. Everyday objects such as smoke detectors use radioactive sources — Americium — to make the air charged to sense particulates indicating smoke. Your air-squirter will operate until the source ...

The only way that I see to extract electricity directly from flowing air without moving parts is by magneto-hydrodynamic separation of charges (separation of charges by the Lorenz force in a magnetic field) To get to this, one would need to make the air conductive and the ionization ratio should be (much) higher than the charges one expect to collect. Which ...

Old steam locomotives were run by steam engines. High-pressure steam was produced in a big boiler and directed through the steam engine. The same type of engine can be supplied with compressed air and be used to drive the electric generator. As Zeiss Ikon commented, steam engines are not compatible with compressed air. Therefore the solution is pneumatic (...

There is no way to do anything efficiently with compressed air. Compressing gasses is one of the most irreversible forms of energy storage you could name. When you compress air to, say, 10 atm., it gets almost hot enough in the cylinder to ignite a fuel (diesel engines typically run between 14:1 and 20:1 compression). That hot air then loses heat into the ...

Dynamotor, and you're done. You can make DC transformers. You just have to spin them. Now, you will get into some commutation issues as you push the voltage higher. You can make the commutator larger and larger (although increasing commutator wear as you do, since the linear speed is the wear issue). But you can probably get about 5000 volts out of ...

Having Edison "invent" the vacuum tube may be viable, but you must suggest a way to produce them in the 1880s Edison is the inventor of the electric bulb - except with a carbon filament. You will need: convince him to declare an armistice with Tesla and push the tungsten filament ahead of time use the so discovered/applied technology, and invent the ...

One easy generator to make is a faraday disk or homopolar generator. And it should easily fit in your specified 2032 battery dimensions. In the image the power is developed between the center axis of rotation and the outer edge, as the disk spins. These power sources generate a great deal of current at a low voltage and have been used to power welding ...

Assuming that this ability was not a big deal prior to the Middle Ages, for simplicity's sake, we'd have some pretty radical changes rather quickly: Blocking electric attacks will be done. Faraday Cage type armor would be work to develop, but it would happen. A metal pole with an insulated handle or gloves for positioning would make an excellent shield. ...

Impossible to use bioelectricty as a deadly weapon between closely matched opponents. If it is deadly for a recipient similar to you, it is deadly for you, as the source, too. The same current needs to pass through you (as the source) as through the destination - being similar to you, his body has a resistance (or impedance) in the same range as you. If that ...

There Would Be Nothing Medieval About It All of human history and behavior would be so radically changed by the ubiquitous ability to shoot lightning that warfare is the least of the changes. Take fire for example. We had to invent bow drills, flint and steel, matches and lighters to start fires. But if you can just zap things there’s absolutely no reason ...
