Earth

“It's currently forecasted that we're going to lose up to 50% of all biodiversity in the next 25 years.”

“You can squeeze water out of a rock, but why? There are better ways to do that right now on Earth.”

“Nuclear electric NEP propulsion is going to be important for going out to the outer planets. If you're staying near earth or even between earth and Mars, probably solar electric is, is, is, is going to outperform it on, on cost and performance just because sol…”

“I think the moon is more important than Mars in the near term, and I think the same thing I was talking about earlier, using the resources of space to offload the crush of resource on Earth.”

“It will cost less to move goods, manufactured goods, processed ore precious metals from the Moon to a specific point on Earth. It will cost less to do that than to ship it using any other terrestrial conventional method, whether that's a boat, an airplane, or …”

“You gotta be going 5000 miles an hour to escape the moon's gravity well, You have to be going 25,000 miles per hour to escape Earths. So, from an efficiency, an energy efficiency standpoint, it's much better to leave from the Moon than to leave from Earth.”

“Humanity has totally dominated the planet, And we keep our closest living relatives in glass boxes so they don't go extinct. And so there's a real history here of greater intelligence being very dangerous.”

“I think it is very possible that the first people to live to a thousand are alive right now. And I think it might be many more people than you think. It's not gonna be like one or two people on earth today.”

“There were three major coronal mass ejections that happened in a row. Two of them kind of combined and hit the earth at the same time. And we had the highest level recorded geomagnetic storm, which was G five.”

“You can completely power Earth with solar panels and batteries and there's no shortage of anything.”

“The window of opportunity to make life multi-planetary exists now for the first time in the four and a half billion year history of Earth.”

“I think we'll have enough mass transferred to Mars within like roughly 30 years to make Mars self-sustaining, such that Mars can continue to grow and prosper, even if the resupply shifts from Earth stop coming.”

“It's a convenient quirk of the scale of the objects in our solar system that if you make the earth a basketball, this is the earth, then the moon is a tennis ball. So in this scale, it's 24 feet.”

“In terms of energy we can give every man, woman, and child on Earth the amount of energy we enjoy here in the United States, which is about 20 barrels of oil per person per year with something like six percent of Earth's surface under solar, which is, It's a, …”

“We will obviously have a lot of solar in space, but I think mostly it'll be for powering applications in space. I don't think people are going to be beaming power down from space to the earth anytime, anytime soon.”

“If you like grow up on the moon, you probably just like can't come to earth because literally just your entire body system will just collapse because it has just not been built around a full one G.”

“When earth is going to encounter an outside force is going to be one of the most unifying forces for our entire planet.”

“First, if you look at it, the active ingredients in pharmaceuticals are fundamentally the highest value, you know, sort of objects by unit mass on the planet Earth.”

“We are now, the earth is now warmer on average than at any point it's been in the last 100,000 years.”

“I feel like with nuclear energy and things like tunnels around our major cities and stuff to get rid of traffic entirely, cause you can have like arbitrarily, you know, large amounts of going in and out. It seems like there's no reason we couldn't have a hundr…”

“At the rate that we consume rare earth minerals and materials, we now have pristine areas that would have to be strip mined to find the last bastion of materials that we're looking for. We don't want to do that. We don't want to destroy our earth. So if there'…”

“We will need to produce five times more energy than we make on Earth today by the end of the century”

“So my personal forecast is the cost of solar electricity will drop by another factor of four. By the time electricity is, by the time solar is about a third of all electricity generation on Earth.”

“We're not that good at building companies. We're not that good at building products. We're not that good at making teams. We're not, like that earth is like maybe a three out of 10 on, on, on, on, on, on, on the score of this.”

“It probably makes a lot more sense to try to take care of this planet and not screw it up than to treat Earth as being disposable and say, oh, it's okay, we're gonna go, we'll have Mars. Because if you keep thinking that way, you're gonna screw Mars up too.”

“The earth has been leaking 40 terawatts, twice as much energy as we humans consume.”

“From a pure geophysics point of view, by some estimates, we have ten billion years of energy reserves below the crust of the earth that we can access in the form of nuclear reserves, geothermal power, and that's excluding, you know, some of the, you know, the …”

“I think we've got 200 years left, maybe, before the Earth is unlivable for humans, and once all the humans are gone, the planet will rebound, the animals will come back, everything will be fine, and a new species will take over.”

“We're gonna run out of phosphorus in about a hundred years. That's how much we're mining out of the ground, and how little there is left.”

“When you combine the unleashed energy potential of plasma fusion systems with the theoretical laboratory scale potential of nuclear synthesis that we see in labs today, And you fast forward a 150 years. I think it's theoretically feasible on a first principles…”

“So arguably someone is alive on planet earth today that could live past the age of 200.”

“Because it's a four and a half hour light travel time. So essentially round trip is nine hours.”

“It seems to me pretty damn clear that the increase in the carrying capacity of the planet over the next century will way outrun the increase in the actual population of the planet.”

“The textile and the garment industry, because it is the second largest polluter on this earth.”

“On the ground, kind of, we're limited to measure things that are that have a signal frequency, which is more than five or 10 hertz or something like that, so we can go a little bit below the human audio band, but not much, and the reason for that is that the e…”
