Energy lost to hydrogen fuel cell
So I have a question about an experiment we did in class.
We used a fan to blow air at a little wind turbine to generate electricity, we connected the turbine to a reversible PEM fuel cell to ...

Can you use the water flow exiting a hydroelectric generator to generate more energy?
In videos of hydroelectric generators I often see that the water that exits a turbine is still moving with significant velocity.
Example of a turbine that has exit water flow with significant velocity:...

Producing Pressurized Hydrogen Underwater Then Using it To Do Work
This is a bit of a weird one but I didn't know where else to ask this.
I was recently talking to my brother and he told me about an idea he had talked with his boss about how to create compressed ...

Can we use the power of ice to float to make free electricity?
ice and water have a volume to weight ratio of 12/11
so 11 tons of ice will support 1 ton of weight
1 ton of ice takes 1000 watts or 12000 b.t.u. of energy to be produced
question is, at what depth ...

How do solar panels and wind turbines prove the law of conservation of energy?
The law of conservation of energy makes sense to me in certain systems but in others I can't seem to comprehend it. For example, a car moves because the stored chemical energy within its fuel is ...

Water turbine power generation for large and small turbines
If you have a small water turbine and a larger water turbine in a river, would the larger turbine produce more power or would they produce the same because of the equal speed of the river?

Optimal speed for the water wheel
The hydroelectricity plants extract the potential energy of highly deployed massive object (water) as it falls down. Without turbine, all that energy would be converted into speed (kinetic energy) at ...

Where does the electricity, generated by a solar panel, go if you don't use the electricity?
I'm sorry if this question is too trivial for this Q&A forum. I am a layman when it comes to physics (though I did cover the high-school physics courses).
I was wondering what happens to the ...

Would a thinner atmosphere (such as high altitude) yield better solar panel energy generation?
I am curious. If you were to put a solar panel up in high altitude or on the surface of the moon, both of which have much less atmosphere to reflect/refract light, would that solar panel produce more ...

Energy storage and battery banks [closed]
Why is it not possible to store windfarm energy in battery banks? A lot of energy isn't being used when wind farms are at peak and we have no way of storing it. This is wasteful. So why don't we use ...
