The possibility of creating a frequency-tunable function generator with rectangular and triangular pulses of constant amplitude and electronic synchronous control of equivalent capacitances in the ...

HDW Electronics' SWG series surge generators are designed with switchable, multi-stage surge capacitors and three voltage ranges. This design offers an advantage over single-stage capacitor units by ...

A new water-integrated droplet electricity generator produces high electrical output while floating on water surfaces. Raindrops are not only a source of fresh water, they also carry unused energy ...

Chinese researchers have recently developed a floating hydrovoltaic device that harvests electricity from raindrops.

I took apart the little freebie 'E-Charger' plane that came with my Aero Ace. All there is to it is a small electric motor, some contacts for the charger, and a big capacitor.<BR><BR>The charger, when ...

Among generator starting professionals, it is widely accepted that the most prevalent reason for generator set (genset) failure-to-start is issues with the lead-acid battery starting system. Service ...
