There 7.68 billion acres of arable land. if everyone did this and lived one one tenth of an acre then that’s room for 76 billion people just on the arable land where there is actually 36 billion acres of land on the planet.

If farming were turned into vertical farming building with ten floors a piece at 1/10th and acre per level that’s 760 billion. At 100 floors that’d be 7.6 trillion. I would need to review an Isaac Arthur video about the maximum occupancy of the planet, there may be heat problems with trillions of people on the planet.

A tenth of an acre would be a square around 65 × 65 feet, or so.

Already renowned for its potential to revolutionize everything from light bulbs and dental fillings through to semiconductors and motorcycle helmets, graphene can now add innate superconductivity to its repertoire. Scientists at the University of Cambridge claim to have discovered a method to trigger the superconducting properties of graphene without actually altering its chemical structure.

Light, flexible, and super-strong, the single layer of carbon atoms that makes up graphene has only been rendered superconductive previously by doping it with impurities, or by affixing it to other superconducting materials, both of which may undermine some of its other unique properties.

However, in the latest research conducted at the University of Cambridge, scientists claim to have found a way to activate superconduction in graphene by coupling it with a material known as praseodymium cerium copper oxide (Pr2− xCe xCuO4) or PCCO. PCCO is from a wider class of superconducting materials known as cuprates (derived from the Latin word for copper), known for their use in high-temperature superconductivity.

If you’ve never heard of an exascale computer before — known unofficially as a super-supercomputer — don’t worry, it doesn’t even exist yet.

But 2017 could be the year that all changes, because China just announced that its world-first exascale supercomputer prototype is due for completion in the coming months. If this thing works as it should, it will be the fastest computer in the world, capable of performing 1 quintillion (a billion billion) calculations per second.

The country’s National Supercomputer Centre announced this week that completion of their prototype is way ahead of schedule, and is expected to be completed in 2017, rather than 2018, as originally predicted.

It’s one of those philosophical questions we occasionally ponder: What is nothing? Can nothing be something? If not, then how can something come from nothing?

If there’s one scientific field on the forefront of such conceptual paradoxes, it’s quantum theory. And in quantum theory, nothing actually is something … sort of.

See, according to quantum mechanics, even an empty vacuum is not really empty. It’s filled with strange virtual particles that blink in and out of existence in timespans too short to observe. Nothingness, on the quantum level, exists on a level of intuitive absurdity; a kind of existence that is paradoxical but, in some conceptual sense, necessary.

I never heard of this sort of making bubbles. And the details given are slim. Anyone here of this?

The first Death Star had a diameter of between 140 and 160 kilometers. The second Death Star’s diameter ranged from 160 to 900 kilometers.

There are two near term technologies which could be applied to making Death Star sized structures:

1. Space bubbles

Nice and will be very useful for many in QC.

Scotland-based route optimization specialist Route Monkey, a unit of telematics and big data company Trakm8, is working on a new generation of transport and mobility algorithms for quantum computers.

Route Monkey already works with Heriot-Watt University in Edinburgh on creating and enhancing innovative algorithms for transport and travel (earlier post). The two are now joining forces with the Networked Quantum Information Technologies Hub (NQIT), led by the University of Oxford. Together, the three organizations will develop, test and commercialize quantum algorithms.

The leap forward in the capabilities offered by quantum computing opens up a whole new field. We can create algorithms that deliver even faster and more accurate answers, to ever more complex transport and mobility challenges.
