SUMMARY

This discussion centers on the feasibility of stepping up electrical power output using stored energy, specifically exploring the concept of using 10 Joules to produce higher wattage for shorter durations. The user inquires whether a system can be designed to discharge energy at a higher rate, such as 20 watts for 0.5 seconds, utilizing energy storage devices like capacitors or batteries. The conversation highlights the principles of energy storage and discharge, emphasizing that while theoretical efficiency can be 100%, real-world applications will experience losses.

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
