New (?) ideas for utilizing space for business: hypergravity for isotopic enrichment

Posted by in categories: business, energy, space

One night, as I was putting my daughter to bed and waiting for her to fall asleep, I tried to think of some new markets for space utilization.

We often hear about attempts to find industrial uses for microgravity for growing crystals, for purification of electronic materials (which is an actual thing with ACME Advanced Materials: http://www.a2-m.com/), maybe growth of certain metal foams, etc. However, in space, you’re in both a hard vacuum and not physically resting on anything, so you can spin up something, and it will simply keep on spinning (stably, if you spin it around the correct axis) nearly indefinitely without any additional energy input and no wear on bearings or anything. So in fact, you can get basically any gravity level you want, including HYPERgravity, nearly for free.

What are the applications of this?

Spinlaunch has $40 million to fund development to first centrifuge space launch by 2022

Posted by in categories: energy, space

SpinLaunch Inc. has closed a $35 million Series A funding round with a powerhouse syndicate of investors. Investors include Airbus Ventures, GV (formerly Google Ventures), and Kleiner Perkins. This syndicate joins institutional investors including Lauder Partners, ATW Partners, Bolt, and Starlight Ventures to total $40 million. Investment funds will be used to scale the team and technology, through first launch by 2022.

SpinLaunch is revolutionizing access to space by developing a kinetic energy launch system designed to provide the world’s lowest-cost orbital launch service for the rapidly growing small satellite industry. Their environmentally responsible approach is unmatched in the industry. SpinLaunch is currently considering four different states for potential launch sites within the United States.

Spinlaunch use large centrifuges to store energy and will then rapidly transfer that momentum into a catapult to send a payload to space at up to 4,800 kilometers per hour (3,000 mph). If successful, the acceleration architecture is projected to be both lower cost and use much less power, with the price of a single space launch reduced to under US$500,000.

Scientists Investigate Bacteria That Could Make Oxygen for Future Martians

Posted by in categories: energy, space

Between the dust storms, thin atmosphere, and frigid temperatures, future Mars colonists are going to have it rough. But they won’t even get a chance to battle the Martian elements unless we figure out a way to supply them with life-giving oxygen. It may seem impossible to do so organically on the barren red planet, but a new Science paper suggests a single Earth organism might be able to do the trick.

In the paper, published Thursday, an international team of researchers report that cyanobacteria, a huge family of tiny organisms that thrive in extreme environments, show promise as oxygen sources for future Mars colonists. Because they are photosynthetic, cyanobacteria thrive on carbon dioxide and energy from the sun, burping up oxygen as a byproduct — just like plants. They’re the ideal fresh air source for Mars, as long as they don’t demand too much sunlight.

“This might sound like science fiction, but space agencies and private companies around the world are actively trying to turn this aspiration into reality in the not-too-distant future,” said study co-author and Australian National University Emeritus Professor Elmars Krausz, Ph.D., in a statement published Wednesday.

Why fascism is so tempting — and how your data could power it

Posted by in categories: business, cybercrime/malcode, energy, holograms

In a profound talk about technology and power, author and historian Yuval Noah Harari explains the important difference between fascism and nationalism — and what the consolidation of our data means for the future of democracy. Appearing as a hologram live from Tel Aviv, Harari warns that the greatest danger that now faces liberal democracy is that the revolution in information technology will make dictatorships more efficient and capable of control. “The enemies of liberal democracy hack our feelings of fear and hate and vanity, and then use these feelings to polarize and destroy,” Harari says. “It is the responsibility of all of us to get to know our weaknesses and make sure they don’t become weapons.” (Followed by a brief conversation with TED curator Chris Anderson)

In desert trials, next-generation water harvester delivers fresh water from air

Posted by in categories: energy, habitats, sustainability

Last October, a University of California, Berkeley, team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight.

The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017: that the harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

“There is nothing like this,” said Omar Yaghi, who invented the technology underlying the harvester. “It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert. This laboratory-to-desert journey allowed us to really turn water harvesting from an interesting phenomenon into a science.”

Berkeley’s desert water extractor is taking us one step closer to harvesting water out of thin air

Posted by in categories: energy, sustainability

Right now, there are roughly 16 sextillion liters of water suspended in the atmosphere. The air around you is a river, you just can’t see it.

Harvesting water from air would be a game-changing solution to tackling freshwater scarcity, which is increasing as the world warms. It would be especially vital in places with very little humidity in the air, like the desert. But while it’s technically possible—you just need to get the water content in the air to condense around something—doing so efficiently has been difficult, until now.

The challenge with this technology is cooling. Water vapor will only condense into a liquid if the material it condenses on is cooler than the surrounding air. That’s why droplets of condensation will appear on a soda can the moment you take it out of the fridge. But how do you leave a piece of machinery in the desert sun all day and keep it cooler than the surrounding air? One way would be to install a cooling system. But it takes a a lot of energy to perpetually cool an object in a hot place, and isn’t feasible in places where energy is expensive. We also don’t want to increase the amount of energy demand in a world already struggling to reduce emissions.

Gym Generates Clean Energy

Posted by in category: energy

I remember about maybe 4’ish years ago someone was working on a sitdown bike looking thing, where if you pedaled it for 30 minutes you could generate enough power to power an average american home for a day. Does anyone know what ever happened with that?
