Can We Harness Gravity As Energy?

I am an amateur astronomer but at the present time, do not see how gravity could be harnessed. Maybe it will be feasible in the remote future.

Why would we need to? Gravity doesn't even begin to register at the macroscopic level unless you're comparing objects many, many orders of magnitudes different in mass. Weakass and pathetic compared to the other 3 fundamental forces. And weak force translates to weak energy.

oh you're an amateur astronomer?

tell us more about your fisher-price telescope.

So what is the strongest fundamental force?

Well strong force can overcome electromagnetism... and it's strong.

Electromagnetism is one of the 4 fundamental forces of universe?

The strong- and weak nuclear forces have limited ranges of influence in contrast to the electromagnetic force and gravity.

Yeah, I'd say "limited range", for sure. Let's go with less than 3 fm.

Meaning...

It is not as feasible, in some applications to "harness' the strong force. Oh, hey, nuclear weapons.

That said. What I was getting at was the range of influence, which is the second factor when it comes to how much energy you'll be able to harness from the strong- and weak nuclear forces.

According to Prof. Moriarty at Nottingham University, courtesy of this Sixty Symbols video, if you were to compare the ratio of the strength of gravity to that of electromagnetism, it would be like comparing the ratio of the weight of a 1 gram object to that of "4 million billion billion billion airbuses". EM is what gives protons their positive charge and makes them repulse each other, but it's the strong force that overpowers that charge and forces them to stick together in an atom's nucleus. It's why so much energy is released when you split an atom.

Then you're breaking the color interaction, a component of strong force. It would send a proton's (or neutron's) quarks flying. Actually you can just watch Scishow's series on the fundamental forces, beginning with strong force and color interaction. Here's the first video:

This is very Interesting topic

And yet both the strong and weak forces have successfully yielded great amounts of energy in the laboratory, and both have had successful military applications, with at least one being a viable(although somewhat expensive) energy source which has already been commercialized.
As far as electromagnetic force is concerned, don't even get started on how successful humans have been in that particular field.

Gravitational force, while having impressive astronomical ranges, simply can't compete with its counterparts in this department.

Any energy that could be gained from falling mass would first require energy to raise that mass. The output just wouldn't be worth the cost. Unless of course mass was taken out of the equation, directly touching on the source of gravity--which would mean observing the mysterious graviton. I'm sensing repulorlifts and andti-grav sleds here.

Nope, I was talking about a device which can literally harness energy from gravitational based interactions, not some gravity dam or other such variation.

Hydroelectric dams don't use solely gravity, which is what I think he wants to hear about. The only reason water flows is due to the Sun, which bombards us with EM.

The general principle is the same as displacing quarks or leptons in fields of the strong- and weak nuclear force, respectively, to generate energy.

The only reasonable conclusion one can draw from your replies is that neither of you have any idea of what you're talking about.
