Our nation is mostly run on fossil views and other nonrenewable technologies, I personally think this will keep us content for roughly 70 years. After, we will be in a rut, and hopefully, before we run out of sources, we could invest in renewable energy.

If you believe in renewable energy, what source do you think would be the wisest? (Wind Power, Hydropower, etc.)

Solar power is the best option, (In my opinion) especially after looking at the Pros and Cons.

i like how my 8th grade teacher described solar energy conservation

solar panels are so expensive, if you buy them for your house now you'll start actually saving money in 30 years!

It would probably take more energy transporting it

the sun already transports it to the ground, thats why you feel heat... if your talking about after you get it isn't that what cables are for?

Transporting it? You would get so much energy off that, it wouldn't really matter the cost of energy transporting it. And, remember, it's energy. Not matter. We can transport it via EM waves. Energy is not matter. Energy is massless and moves at the speed of light.


Not really... we currently do not have the technology to harness solar power to even 10%. According to popular science, after studying photosynthesis scientist have come up with a way for 20% electricity harness. To transport the energy, you'd have to store it, otherwise it would disperse. The technology for wireless charing is only effective for up to a few feet (otherwise people would stand near power lines stealing electricity)

Also, cold fusion is an option, but what happens when you run out of the right materials? You could try fissioning, but then you'd run out of the right materials too. You'd end up with iron in both cases, which gives no energy from fission nor from fusion.


No the final final product for fission is lead, after all the atoms have decayed into the most stable state.

The final product for Fusion is just water. there is no iron in any of them, but good try.

Your science is outdated. The final final product for radioactive decay is lead, but the final product for fission and fusion is iron. In the core of stars, elements are fused, until finally, the hydrogen and helium run out, so the stars fuse bigger elements, until they try to fuse iron. When you try to fuse or fission iron, it takes exactly the same amount of energy to fuse or fission it as it releases. That is why large stars go supernova when they try to fuse or fission iron. So if you just continue fusing and fissioning elements, all you'll end up with is iron.

Derp

Yea thats what I meant.

Yea my science and knowledge on fission is from 5 years ago when I was in 8th grade. It is hella outdated.
But I will look into this and provide a suitable rebuttal.

You'll still end up with vast amounts of iron, with nothing to do with them.

But I have to go to bed now, so I will leave it up to you to see the wisdom of my words.

Ok, usually when you do localized hot fusion you don't fuse iron.

In AP (advanced placement) physics they don't teach theories, they teach real stuff, and electricity...

...No theories in AP physics??? (Yes, I do know what it means.) What is this world coming to????

And anyways, of course you don't fuse iron, you won't get any energy from it! That's the whole point!

exactly so the final product of a normal fusion is water!
and fission is like Bi and something else, and after it finishes decaying, lead.

ummm...And then you try to fuse water...and get repeatedly heavier elements until iron. And when you fission Uranium, yes, you do get Bi, and Krypton, but if you continue fissioning those, you will get iron. And nuclear decay and nuclear fusion are two almost completely irrelated things. XD Well, at least in this conversation.

You actually would not continue fusing/fissioning them because.
1. fusion is currently only in the thought process, but once the Hydrogen pellets are spent the energy output is actually less than the energy inputed to sustain fusion so you would not continue fusion.

2. You would not continue fission of the products because like stated above the energy output< input. So it is inefficient to continue fission on a commercial level

I'm sure the stars do that, probably because they only have a set amount of material, while nuclear power plants receive fuel rods use it, then dump it.

Actually, you could fission things past uranium, but once you get to iron, then the energy output<input. But, again, what happens when you run out of uranium and plutonium? (Actually, plutonium is a transuranic element, not found on the earth, so it is made from uranium-238)

But, you know, technically, this post is sorta useless, read this story.

Yea that I actually know from AP chemistry

But generally when they dump the fuel rods it is no where close to all Iron, because then it wouldn't be radioactive would it.
