​@Tristan M My apologies if I misrepresent your argument; it's hard to parse. Especially the part where little Force-generating things publish papers. * I don't understand how you can say that patents _aren't_ a monopoly. That is literally their purpose-they give the patent-holder the exclusive right to use or license whatever the patent is for. That is a monopoly. * Governments do have a monopoly of force, yes. I don't see how that's relevant to my statement, especially since I never said that a government holding the exclusive rights to use/license/etc graphene tech would be a good thing. * Ideally, graphene-related technology would be in the public domain, like e.g. paper-making and the printing press are. I understand the logic behind intellectual property rights, but that doesn't mean I have to like the effects it can have when corporations hold the rights to their employees' inventions. Especially when, as is often the case, the research was funded by government grants. * I'm not sure if I should criticize you for your regurgitated anti-intellectualist rhetoric or your poor grasp of grammatical conventions, like capitalization and sentence structure. But I suppose those two go hand in hand. English teachers are probably in on the conspiracy.

While the use of phosphorus was a good choice due to the allotrope analogy, phosphorus is in the nitrogen column. It also has 3 electron holes generally available for covalent bonding. The tetrahedral allotrope demonstrates this by how each atom is bound to three others. It's not my intention to be pedantic, but the statement about the bonding sites was in error. Carbon's next twin chemically would actually be silicon. This columnar period behavior on the table shows why lead is so bad: being in the same column, it occasionally replaces carbon atoms in organic molecules, making removal of lead problematic for organisms. In practice, yes, phosphorus can also donate 5 electrons, but that's a rarer configuration, and if I recall correctly that's more common in ionic bonding.

I often forget to like your videos because they are so professional I forget that I am watching on youtube.

apparently researchers have found a way to actually generate a usable current with graphene from the thermal motion of atoms, aka Brownian motion. something previously thought impossible. graphene just keeps getting better.

NGL Isaac that's one of the worst mispronunciations of my last name I've heard. I'm impressed lol. In all seriousness working on this episode with you all was awesome. I need to get back into our brainstorming and editing sessions soon. Once my job lets up a bit.

What’s your opinion on turbostratic graphene? It’s sometimes known as flash graphene. Do you think it has a future?

Hi Isaac. I listen to your voice so much, I've grown to love it. Can you answer a question? What is the name of the allotrope of carbon I'm thinking of? A picture would help, but I don't think I can post pictures in KZbin comments. It is also a 2D sheet, but composed of hexagons, squares, & dodecahedrons, in a regular pattern. Do you at least know the name of the pattern of which I speak? Anyway, the dodecahedrons would make good holes for molecules to go thru, when you need holes.

One quick note on hydrogen embrittlement and how graphene can prevent it. Hydrogen embrittlement is one of the main problems the space shuttle hydrogen tank had (the big orange tank) and why we're tending toward methane as a primary rocket fuel instead of hydrogen even though hydrogen gets you higher isp. If you had a hydrogen tank, but lined on the inside with graphene, it would negate that problem entirely, possibly reopening the door for hydrogen as a primary rocket fuel.

I wonder what impact a space elevator would have on the ozone layer? Would it tear it up like a rocket, or leave it preserved?
