Two Martians Walk Into A Bar

Two Martians walk into a bar, and Elon Musk turns to the other Martian and says, "I heard Earth is flat." The other Martian looks at him incredulously and says, "Elon, you're an alien! You've seen the curvature of the universe with your own eyes!" Elon just shrugs and says, "Eh, I guess I just haven't been paying attention." The bartender overhears this exchange and chimes in, "Well, I guess this bar is the only place flat-earthers are welcome."

Elon Musk's Neuralink Is No Scam, Just A Startup With A Long Horizon


Trying to collect digital information from a drop of blood should be much less challenging than playing piano with the brain, and Elizabeth Holmes had 10 years before she was hounded out as maybe a thief and a scammer, but Musk's Neuralink has already run for five years, and I don't think the promised delivery will be made in another five. Both have had Steve Jobs comparisons. I think Musk is validly compared to Jobs. 

2020, the year of the Coronavirus, is the Netscape year for biotech. 

The elephant in the room is gender. Musk seems to have a longer runway because he is a man. And I do think Musk is quite off on the idea of human habitation of Mars. The rocket part is fairly easy, though plenty challenging. The hard part is the human body is designed for the earth's surface. Lack of gravity is disorienting and debilitating for many organs. Mars is more hostile than the deep ocean, and we have not colonized the deep ocean. I'd rather fund the Green New Deal than attempt Mars. It is fairly basic biology. If you can't get the eyes, you should not attempt the brain. Eyes start bulging out during prolonged loss of gravity leading to permanent sight damage. 

I am strong on Tesla. I have consistently been. I am also strong on robotic mining of asteroids.

NEOM Beats Mars

If you have read three articles on NEOM, it is fair to say you are no NEOM expert, and I am no NEOM expert. I expect to read up on it a little bit more. But sometimes it is an advantage to have read less. That gives you a freshness of perspective.

NEOM: Wide Participation Will Enhance Chance Of Success
NEOM, Jerusalem: Twin Cities?
My Take On NEOM, The City
NEOM: A City

Every astronaut has been an athlete. You need to be in an absolute great shape physically to experience that pressure on your body when the rocket accelerates at rocket speed to get out of the clutches of earth's gravity. This means everyone who buys a ticket from Elon to go to Mars will have to attain that athlete status. And that's for the first part of the journey when gravity is a big problem. Then you have a nine-month journey of being in a no gravity zone. That actually is harder on the body. Lack of gravity is very challenging for your bones, for your eyes, for your body in general. And there no amount of physical training can prepare you.

But NEOM does not have that Mars problem. NEOM is on earth. Mars has been sold as a fresh start for humanity. NEOM can be that fresh start. But it has to be a fresh start in many ways. It has to be a fresh start politically, economically, technologically.

NEOM needs peace. NEOM needs the Saudi-Iran regional cold war to end. NEOM needs genuine peace between Israel and Palestine. Peace is necessary infrastructure.

Also, NEOM is not going to have, so what air do we breathe issues. It is not going to have radiation issues. Earth has a magnetic field that protects it from solar radiation.

There are also psychological issues. If you keep people in a small space for too long, many get claustrophobic. And they start acting up.

Is Elon Musk Just Getting Started?
Elon Musk's Giant Blind Spot: Human Beings

Humans Will Never Colonize Mars The Red Planet is a cold, dead place, with an atmosphere about 100 times thinner than Earth’s. The paltry amount of air that does exist on Mars is primarily composed of noxious carbon dioxide, which does little to protect the surface from the Sun’s harmful rays. Air pressure on Mars is very low; at 600 Pascals, it’s only about 0.6 percent that of Earth. You might as well be exposed to the vacuum of space, resulting in a severe form of the bends—including ruptured lungs, dangerously swollen skin and body tissue, and ultimately death. The thin atmosphere also means that heat cannot be retained at the surface. The average temperature on Mars is -81 degrees Fahrenheit (-63 degrees Celsius), with temperatures dropping as low as -195 degrees F (-126 degrees C). By contrast, the coldest temperature ever recorded on Earth was at Vostok Station in Antarctica, at -128 degrees F (-89 degrees C) on June 23, 1982. Once temperatures get below the -40 degrees F/C mark, people who aren’t properly dressed for the occasion can expect hypothermia to set in within about five to seven minutes............. The notion that we’ll soon set up colonies inhabited by hundreds or thousands of people is pure nonsense.......... Gravity on the Red Planet is 0.375 that of Earth’s, which means a 180-pound person on Earth would weigh a scant 68 pounds on Mars. While that might sound appealing, this low-gravity environment would likely wreak havoc to human health in the long term, and possibly have negative impacts on human fertility. ........ the unfulfilled visions proposed during the 1940s and 1950s........ “Back then, cover stories of magazines like Popular Mechanics and Popular Science showed colonies under the oceans and in the Antarctic,” Friedman told Gizmodo. The feeling was that humans would find a way to occupy every nook and cranny of the planet, no matter how challenging or inhospitable ........ “But this just hasn’t happened. We make occasional visits to Antarctica and we even have some bases there, but that’s about it. Under the oceans it’s even worse, with some limited human operations, but in reality it’s really very, very little.” As for human colonies in either of these environments, not so much. In fact, not at all, despite the relative ease at which we could achieve this...... Unlike other fields, development into human spaceflight, he said, “has become static.” Friedman agreed that we’ll likely build bases on Mars, but the “evidence of history” suggests colonization is unlikely for the foreseeable future........ astronauts on the ISS, who are subject to tremendous muscle and bone loss, try to counteract the effects by doing strength and aerobic training while up in space. As for treating the resulting negative health impacts, whether caused by long-duration stays on the ISS or from long-term living in the low-gravity environment of Mars, “we’re not there yet” ........ It’s a dangerous delusion to think that space offers an escape from Earth’s problems. We’ve got to solve these problems here. Coping with climate change may seem daunting, but it’s a doddle compared to terraforming Mars. No place in our solar system offers an environment even as clement as the Antarctic or the top of Everest.

There’s no ‘Planet B’

....... Martian terraforming is a pipedream, a prospect that’s “way beyond any kind of technology we’re going to have any time soon” ....... radiation on Mars is far worse than we thought, adding that “we don’t have the long-term solutions yet, unless you want to risk radiation illnesses.” Depending on the degree of exposure, excessive radiation can result in skin burns, radiation sickness, cancer, and cardiovascular disease........ Life in a Martian colony would be miserable, with people forced to live in artificially lit underground bases, or in thickly protected surface stations with severely minimized access to the outdoors. Life in this closed environment, with limited access to the surface, could result in other health issues related to exclusive indoor living, such as depression, boredom from lack of stimulus, an inability to concentrate, poor eyesight, and high blood pressure—not to mention a complete disconnect from nature......... we don’t see colonists living in Antarctica or under the sea, so why should we expect troves of people to want to live in a place that’s considerably more unpleasant? ....... for prospective families hoping to spawn future generations of Martian colonists, it’s borderline cruelty. ...... Studies of astronauts who have participated in long-duration missions lasting about a year exhibit troubling symptoms, including bone and muscle loss, cardiovascular problems, immune and metabolic disorders, visual disorders, balance and sensorimotor problems, among many other health issues. ...... Some astronauts, like NASA’s Scott Kelly, never feel like their old selves again, including declines in cognitive test scores and altered gene function. ........ The regolith, or soil, on Mars is toxic, containing dangerous perchlorate chemicals, so that also needs to be avoided. To grow crops, colonists will likely build subterranean hydroponic greenhouses. This will require specialized lighting, genetically modified plants designed specifically for Mars, and plenty of water, the latter of which will be difficult to source on Mars.........

We may be stuck on Earth.

Elon Musk's Giant Blind Spot: Human Beings

There is this no small detail called gravity. It is big, it is fat.

And gravity is physics. And Elon Musk has a degree in physics from U Penn. He must know his physics because he seems to send rockets out into space at will.

But Elon was no biology major, looks like.

There is this funny thing called gravity. The human body needs the earth's gravity. That is why long term human habitation on the moon is a bad idea. Robots? Yes. Human beings? No, no.

In absence of gravity, your eyes might bulge out. Your joints might start getting, well, disjointed. Your bones need gravity to stay bones.

But Elon stays oblivious to the fact. He says everyone who signs up for Mars will get 10 cubic meters of space inside his spaceship, "which is a lot."

And that's just gravity. Radiation will have to be another blog post. Radiation might make those ten cubic meters a microwave experience, which is a lot. Like, too much.

It is not like Elon does not have enough on his plate. There are trillions to be made through robotic asteroid mining. Spices used to be like gold. Gold can become like spices. I want his 10,000 satellites to provide gigabit broadband every point on earth. I like the idea of any point on earth to any other point on earth in 30 minutes. You escape zero gravity before the bones figure it out. Hyperloop is massive. I have an entire real estate tech startup around the Hyperloop concept. Tesla? I want one. Solar tiles on the roof? I want. Super cheap, super boring tunnels? I want them. Although it could get literally boring down there unless the walls of those underground vehicles come alive and are entertainment.

Save earth like this is the only planet we got. There is no other. Plant a trillion trees. Elon should design some drones that will plant those trillion trees. And his satellites should map out the earth to find out every patch of land where trees can be planted. And let's get it done and over with already.

Somebody drop an apple on Elon's head.

Africa Is Mars

Mars is undoable. Mars is undesirable. There is this funny thing called gravity. The human body does not do well in the absence of gravity. Send robots. They are gravity neutral. But people? Africa is plenty undiscovered. Plant a trillion trees instead. Save this very planet instead.

When you plant the Australian eucalyptus in a new climate, there is havoc. Imagine a microbe from Mars coming over to earth. What could happen?

The best point for rockets are one step further and one step closer. I am all for robotic mining of the asteroid belt. Countries used to go to war over spices. Gold is the new spice. I am all for internet access on every point on earth through 10,000 or more satellites.

But I am all about Africa, not Mars. Ray Youssef has an edge over Elon Musk in that regard. Mars might be Elon Musk's masterstroke in marketing, not an actual place he wants to go to. Look, Mars! He says. And then builds boring tunnels and exciting cars.

Both Ray and Elon are immigration success stories. Both are out of Africa. Elon might look like he has white skin, but you just have to read his life story to realize the sickness that was apartheid also brutalized him. Elon grew up in South Africa. Ray's parents came from Africa. Ray is a New Yorker. And now Ray is America's gift to Africa. These two inspiring entrepreneurs are in stark contrast to the stupidity emanating out of Washington. So much garbage is being talked about immigration. To Ray I might say, go back to Africa. But looks like he is already there.

Asteroid Belt And Earth On The Way To Mars

Spending a year in weightless space is a nightmare for the human body. But the push for Mars might have benefits closer to home. And robotic travel will harvest the asteroid belt. A few hundred years ago spices were scarce and literally gold. The asteroid belt could turn gold into a commodity.

Delhi to Tokyo in 30 minutes, says Elon Musk. That translates to anywhere to anywhere on earth in 30 minutes. That is more alluring for human tourism (and commerce) than zooming vertically to the boundaries of from where all you see is pitch black before you come back.

But if you move information well enough, fast enough, in large enough quantities, securely enough, and from every point to every other point on earth, human beings perhaps can get by on less travel in the first place. The vision of 4,000 satellites carrying the bulk of internet traffic is sound. And it beats going to Mars. Such a spacenet would be indispensable for the Internet Of Things with its hundreds of billions of sensors, its top use being to keep the earthly ecosystem at its optimum best. Human safety and security would be a whole new paradigm.

Elon Musk: To Mars Or Not To Mars

I say no Mars. It is basic. I don't mean to spoil the fun and sound like I were saying the emperor is naked. But the human skeleton is not designed for Mars gravity. Or for the months of space travel. It would simply give up.

But reusable rockets are a great concept. The financials are in the robotic mining of the asteroid belt and, more immediately, in the network of 4,000 satellites that would carry a big chunk of the load of internet traffic. The need for bandwidth is going to grow exponentially. Both would be tremendous money makers. And robots don't have skeleton issues. Good thing.

The earth is the only home. And Elon Musk should really double down on solar. Create a Musk Law whereby costs are halved every two, or three or four years. Dirty needs to be driven out of business.
Electric vehicles go hand in hand with that.

And what's up with the hyperloop? Again, I have human body questions. All that acceleration and deceleration, how would the human body react to that? But if the hyperloop be possible then you will see an Amazon size forest in America before 2050. Good thing. People would congregate in the big cities of the world.

Mars is for the Curiosity rover. Robotic exploration is the best way.

Watch NASA’s Dawn Spacecraft Buzz Dwarf Planet Ceres in the Asteroid Belt
Ceres accounts for 25% of the mass of the asteroid belt, and unlike most of its irregularly shaped neighbors, it is massive enough to be nearly spherical like a moon or planet. ..... Models of the dwarf planet’s interior suggest its mantle may consist of a slurry of water and dirt that contains more fresh water than Earth. .... early images from the Dawn mission showed mysterious bright spots on the surface .... highly reflective patches of surface ice are one possibility. ...... Discovering water on Ceres would have implications for space exploration. Water is a potential source of hydration, breathable air, and rocket fuel, and will therefore prove a precious resource for space wanderers. .... Ceres would make a good extraterrestrial outpost. Its low gravity makes landing and taking off less energy intensive, and resources on the surface could resupply missions—perhaps even trips to the outer solar system.

Internet Satellites? Now You Have My Attention, Elon

Mars is esoteric to me. I already know what's on Mars. Earth is way more exciting. Glad to have you back on earth, Elon.

$100 Billion Plan To Save The World
Elon Musk’s Next Mission: Internet Satellites
Elon Musk shook up the automotive and aerospace industries with electric cars and cheap rockets. Now, he’s focused on satellites, looking at ways to make smaller, less-expensive models that can deliver Internet access across the globe ..... launching around 700 satellites, each weighing less than 250 pounds ...... it would cost $1 billion or more ..... hopes to bring the cost of manufacturing smaller models under $1 million

Mars Is Kind Of Far

What will humans do that robots can not? Mining the moon for energy is a better proposition, I think. But never say never.

The Deferred Dreams Of Mars
people communicating with a large and sophisticated piece of equipment 150 million miles away as it began to carry out experiments that should enhance our understanding of whether the planet has or has ever had life ..... six astronauts could be sent on six-month flights to Mars and what they would do there for a year and a half before their six-month flights home ...... NASA could perpetually remain 20 years away from a manned Mars mission. ..... a Mars crew would see Earth shrink into just one of billions of twinkles in space ..... the astronauts would have to survive in a freezing, windswept world with unbreathable air and 38 percent of Earth's gravity ...... systems for feeding them, sheltering them ..... the benefits are mostly intangible ..... right now Curiosity is exploring these very questions, firing lasers at rocks to determine their composition and hunting for signs of microbial life ..... Because of such robotic missions, our knowledge of Mars has improved so much in the past 15 years that it's become harder to make the case for sending humans. ...... "For the cost of sending one human to Mars, you could send an entire flotilla of robots." ....... the space shuttle would fly 135 times from 1981 through 2011 .... Going into space for more than two years would subject the astronauts to an unprecedented degree of isolation and extended weightlessness; the longest stay in space so far has been 14 months. Poten­tially deadly cosmic rays, which are blocked by Earth's magnetic field and atmosphere, would hit the spacecraft in flight and threaten the astronauts on Mars. ..... the sky crane used to land Curiosity wouldn't work for landing humans, whose craft could weigh 30 times more ...... something entirely new: protect and feed humans on another planet over a long stretch ...... "closed loop" life-support systems in which water and air are recycled ....... possible to extract oxygen from the carbon dioxide that makes up 95 percent of the Martian air. ..... dehydrated food that astronauts inject with water on the space station can retain adequate nutrients for five years ...... Pressure-treating the food ..... make the habitat inflatable, so it could be packed tightly en route to Mars. ...... the bone loss, blurry vision, and other problems astronauts suffer when removed from Earth's gravity ...... compared with the money and effort that get spent in the service of "greed and our ancestral urge to beat the crap out of each other." ...... colonizing the moon, stimulating space tourism, and harvesting solar energy from geosynchronous Earth orbit
