Discussion Overview

The discussion revolves around the possibility of stepping up power output (watts) using a limited amount of energy (joules) over a shorter time frame. Participants explore concepts related to energy storage and discharge, including electrical and mechanical analogies.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant proposes that with 10 joules, it is possible to produce 10 watts for 1 second, questioning if this energy can be stepped up to 20 watts for 0.5 seconds.
  • Another participant suggests considering energy storage systems, such as rechargeable batteries or capacitors, to release energy later.
  • A participant emphasizes the limitation of having only a fixed amount of energy available and suggests that reducing the time of output is the only option.
  • Some participants discuss the function of rechargeable batteries and capacitors in storing energy and question the feasibility of discharging at a higher power for a shorter duration.
  • There is a reiteration of the idea that while theoretically possible, practical efficiency issues would prevent achieving 100% efficiency in energy storage and discharge.

Areas of Agreement / Disagreement

Participants express varying viewpoints on the feasibility of stepping up power output with limited energy. There is no consensus on whether this can be achieved practically, as discussions about energy storage and efficiency highlight differing perspectives.

Contextual Notes

Participants acknowledge the limitations of their proposals, particularly regarding efficiency and the nature of energy storage systems. The discussion remains open-ended with unresolved questions about practical applications.

TL;DR
Can I step up watts using some kind of transformer ?
Hello, if I have an available amount of Joules say 10 I believe I can produce 10 watts for 1 second.

Is it possible to use some kind of step up system using my available 10 Joules to step up to 20 watts but for only 0.5 seconds ? And so on like a kind of electrical ratio system.

Can you think of anything that can be used to store electrical energy and release it later?

Or if this does not need to be electrical energy, think about what a water tower does.

I can't store it to build it up because I only have the available energy. All I can do is reduce the time to output the electricity.

What does a rechargeable battery do? Or a capacitor?

If I have an available 10 w of 1 second, if I had a capacitor or battery with 100% efficiency I could store 10 w. Could I discharge it at 20 w for 0.5 seconds ?

Just as an example obviously the efficiency won't be 100 %

Yes I've just confirmed it, thanks very much
