Next Big Future

Gigawatt Scale Moon Base

SpaceX had published a picture of a moonbase with multiple Starships and a solar farm. On earth, a photovoltaic solar plant producing about one 1 GWh per year, will require around 2.8 acres of land. The moon has no atmosphere, so a 300-watt panel on Earth would produce 400 watts on the moon. A GWh…

Chinese Hypersonic Missile Engine Triples US Duration Record

A team led by Fan Xuejun at the Institute of Mechanics under the Chinese Academy of Sciences has developed a type of scramjet that ran continuously for 600 seconds in a ground test, Weihutang, a program on military affairs affiliated with state broadcaster China Central Television (CCTV), reported on over the weekend. This broke the…

Early SpaceX Starship Will Stay as Moon Bases

Elon has tweeted out that early Starships will stay on the moon as part of moon base alpha. The SpaceX plan is what Nextbigfuture described in last months article “A Sky Full of Starships”. The SpaceX Starship will have six Raptor engines but will still be larger and cheaper than the external fuel tanks of…

Reviewing the World and the Rest of Your Life

18 months ago, Nextbigfuture looked at the World and the rest of the life of a middle aged person. There was a consideration super-technology, debt, growth, jobs and living the next 45 years. World Jobs Now 18 months ago the world was at 5.6% unemployment. Now, the UN’s International Labor Organization predicts 1.6 billion informal…

Each SpaceX Starlink Satellite Has Over 60 Computers

SpaceX software engineers answered questions on Reddit. Each launch of 60 satellites contains more than 4,000 Linux computers. The Starlink constellation has more than 30,000 Linux nodes (and more than 6,000 microcontrollers) in space right now. Starlink shares its Linux platform infrastructure with Falcon and Dragon. Starlink get the benefit of our more than 180…

Progress to Large Scale Memristor Neuromorphic Computing

1. A memristor has been proposed as an artificial synapse for emerging neuromorphic computing applications. (Nature Nanotechnology) To train a neural network in memristor arrays, changes in weight values in the form of device conductance should be distinct and uniform. An electrochemical metallization (ECM) memory typically based on silicon (Si), has demonstrated a good analogue…

Finally, Commercialization of Wafers of Carbon Nanotube Transistor Chips

Carbon nanotube field-effect transistors or CNFETs can now be made 1100 times faster so significant commercialization will finally happen. CNFETs are more energy-efficient than silicon field-effect transistors and could be used to build new types of three-dimensional microprocessors. They found that dry cycling, a method of intermittently drying out the submerged wafer, could dramatically reduce…

Tesla Battery Control Electronics Are Vastly Superior

Sandy Munro tears apart Tesla EVs to understand exactly how they are made. Sandy says that Tesla is able to control power output to 2-3 millivolts for every group of 46 batteries. Tesla made the right choice to use cylindrical batteries. Everyone in the car and electric car game thought that thousands of cylindrical batteries…

Tesla Could Become the Largest Global Car Maker by 2025

Tesla has 80-90% of the electric vehicle market share in the USA. The traditional carmakers have failed to make good electric cars. This seems likely to continue for another three years. The cars that have been announced will not get ahead of the vehicles that Tesla will be making. All of the new electric vehicles…
