" ways to make one." Not manufacturing a battery for mass market. There are plenty of battery tech that has been discovered which hasn't made its way into the general public, but is easily capable of being made with very little equipment. But my goal is to focus more on finding better and better...

There in lies the issue. I'm not talking about creating a battery. I'm more discussing the science behind it. Talks on the technology and ways to make them better, etc etc. I'm not saying we would make a business and sell said batteries...

I understand that's the consensus, but there have been quite a bit of breakthroughs that require little to no expensive equipment. With that said, it would be a place for providing the knowledge. Obviously, people don't really agree with that, so it's fine. That's why I asked. I just feel many...

But what is the real limiting factor? Is it power source, heat sinc or what? I mean what exactly makes a laser more powerful? It can't be the power given to the atoms because that just creates a higher excited state, so it simply means a different wave of protons. Do you pack more atoms in a...

I believe many of you might have misunderstood what I mean. I don't mean an open source battery based on modern battery tech like lithium ion. I mean experimentation and discussion on new ideas for superior batteries. It would essentially be more on material sciences with the goal of a better...

What's up everyone. I've been interested in batteries for quite some time now, as practically every project I ever undertake is hindered by current battery technology, and it seems every potential startup is hindered by gaining capital, etc etc. I was curious what people here felt about a open...

If you excited the atoms and injected them with different wavelengths, it could theoretically create a multicolor laser then? Obviously the colors would mix though. I would think this would be easier than keeping it at one wavelength. Then again, they wouldn't be as tightly grouped and...

Thanks for the explanation. I figured you could, but there are clearly far more efficient items to use.

It seems there is a ceiling for how powerful a laser can be in a certain size. I was wondering if this is due to material costs or if it is literally impossible to have like a 50 watt laser the size of a pen. I have no doubt it comes down to power levels etc. I'll bet many of you are excited for...

What's up everyone. I'm really liking the idea of lasers and I find it really interesting how they can burn small things with just a beam of light. The thing is that I can't really find anywhere that a person actually builds the laser from the ground up. Is it possible to build everything like...

Basically, what I understand is that when the atoms are excited and then lower into the ground state, they "shed", for lack of a better word excess energy as a photon. Then, as the photons bounce back and forth through the mirrors, this makes the excited atoms that haven't gone back to the...

I meant photon. My mistake. Shed photons, and I also didn't really mean shed, but I couldn't think of the word.

Also, you could use an LED to cause the atoms to go into an excited state, right? I think that's what he was asking. I don't really know why you couldn't. It would just be used instead of say electricity. Now, the LED would have to be pretty powerful to do that of course.

I guess I'm a little confused now. I thought I was correct in my assumption. I understand a population inversion is required. That's why I mentioned that different wave lengths can cause this, but I didn't know most atoms only shed 2 protons with one particular wavelength. I knew that certain...

Oh okay. So does it require a particular gas because certain materials can only stimulate photons at certain frequencies, but that gas can stimulate photons at multiple frequencies?
