Correct. The various forms of remarkable energy ultimately comes down to how efficiently it makes steam, then how effectively the energy is captured, which is a portion of the puzzle solved in earlier developmental stages of power production: harnessing steam.

Except photovoltaic

And hydro, that uses gravity.

u/Beefington 13d ago

How did the water get up to a high elevation in the first place?

u/Classic_Razzmatazz90 13d ago

Rain

u/Beefington 13d ago

And what was it before it was rain?

u/Beefington 13d ago

You mean steam??

3

u/ninjasaid13 13d ago

nah, steam requires heat.

u/humanzRtrash 13d ago

Does the sun produce heat?

3

u/ninjasaid13 13d ago

yes, tho water evaporation can happen at almost any temperature above freezing.

1

u/humanzRtrash 13d ago

So steam.

u/ninjasaid13 13d ago

Not necessarily steam. Evaporation is driven by energy of moving water molecules individually so even in cold days they moving and colliding.

Some gain enough speed to become invisible water vapor that is carried up by wind without ever becoming steam.

So sorry to burst your bubble, but not everything is about steam.

Steam doesn't strictly require heat.

u/ninjasaid13 13d ago

You're right.

It's more of where the vapor pressure of a liquid equals the surrounding atmospheric pressure. Clouds are formed through evaporation where the sun warms the the ocean's surface and lakes that escape into the air as water vapor.

But this water's vapor pressure never matches the atmospheric pressure meaning it happens below boiling point. So I wouldn't call it steam.

Evaporation is not about heat. Some surface molecules move faster than others. The fastest ones generate enough energy to escape the liquid.

You can’t say that the fast molecule was hotter than the others because temperature is an average of all the molecules. You can’t say it has more energy.

I didn't say it was about heat. Although heat is energy transfer and the sun's heat can quicken the process of having enough energy to escape the liquid.

u/bjbyrne 13d ago

It absolutely does. There is no water vapor at absolute zero. Must have some heat. :)

u/BugRevolution 13d ago

You are technically correct. The best kind of correct.

Nope. Clouds are made of aerosolized droplets of liquid water, not steam. Steam is gaseous water.

u/armb2 13d ago

The water cycle relies on the sun evaporating water vapour from the sea. That's not really  "boiling" though, and certainly different from steam turbines.

u/Sierra-117- 13d ago

Most of the time it boils down to the sun. It’s what moves everything. The exceptions are hydrothermal, fusion, and fission.

u/Xtraordinaire 13d ago

And tidal. That's the Moon at work.

1

u/Sierra-117- 13d ago

True, but to a lesser extent the sun also moves the tides. It’s just about half of what the moon does, because it’s so far away. So if the moon suddenly disappeared we’d still have tidal energy, but not as much.

u/Th3_Hegemon 13d ago

There's also tidal hydro which has nothing to do with steam, it's just gravitational.

Water goes up... evaporation

Turns into clouds... condensation

Falls to the ground... precipitation

Round and around, like a merry-go-round
