Startup Launches Refueling Station Into Orbit, Gets $10 Million in Funding

Posted by in categories: energy, satellites

In June, San Francisco-based startup Orbit Fab launched a prototype refueling station into Earth’s orbit — but rather than allowing astronauts to venture into deep space, this system is meant to give old satellites a new lease on life.

That’s a compelling idea, and now the company has locked down $10 million in funding to further it. Our planet’s orbit is getting cluttered with old and new satellites, increasing the risks of a collision and adding to an existing space junk problem.

Orbit Fab’s Tenzing Tanker-001, an early prototype satellite fuel tanker, launched into orbit as part of SpaceX’s Transporter-2 rideshare mission on June 30.

Quantum mechanics for plants

Posted by in categories: economics, energy, quantum physics

Circa 2004


To what extent do photosynthetic organisms use quantum mechanics to optimize the capture and distribution of light? Answers are emerging from the examination of energy transfer at the submolecular scale.

The first law of photosynthetic economics is: “A photon saved is a photon earned.” Research into the factors behind this principle has been burgeoning, and has recently culminated in a paper in Physical Review Letters by Jang et al.1 in which the authors look at photosynthetic energy transfer at the quantum level.

A spoonful of sugar opens a path to longer lasting lithium sulfur batteries

Posted by in categories: drones, energy, engineering, food, sustainability

Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.

The Monash team, assisted by CSIRO, report in today’s edition of Nature Communications that using a glucose-based additive on the positive electrode they have managed to stabilize lithium-sulfur battery technology, long touted as the basis for the next generation of batteries.

“In less than a decade, this technology could lead to vehicles including electric busses and trucks that can travel from Melbourne to Sydney without recharging. It could also enable innovation in delivery and agricultural drones where light weight is paramount,” says lead author Professor Mainak Majumder, from the Department of Mechanical and Aerospace Engineering and Associate Director of the Monash Energy Institute.

Transforming ‘sewer gas’ into clean hydrogen fuel

Posted by in categories: chemistry, energy, engineering, sustainability

Scientists have found a new chemical process to turn a stinky, toxic gas into a clean-burning fuel.

The process, detailed recently in the American Chemical Society journal ACS Sustainable Chemical Engineering, turns —more commonly called “sewer gas”—into . Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

The process detailed in this study uses relatively little energy and a relatively cheap material—the chemical iron sulfide with a trace amount of molybdenum as an additive.

Entergy Restores Power To Half A Million Customers But Large Parts Of Southeast Louisiana Are Still Dark

Posted by in category: energy

Entergy has restored power to more than half a million of its customers, Louisiana’s largest utility said Tuesday morning.

But there are still roughly 370,000 customers without power across the state, with about 50,000 of them in New Orleans. Entergy expects 90% of its customers in the city to have power back Wednesday.

Some neighborhoods such as Venetian Isles will likely take longer due to more damage in those areas. Details of power restoration timelines for specific neighborhoods in New Orleans can be found here.

This Insane Bus Was Pure ELECTRIC & Didn’t Need Batteries

Posted by in categories: drones, energy, sustainability

All the way back in the 1940s, in Switzerland, work was underway on a breakthrough Bus that would be pure electric, and not need batteries. Introducing the Gyro-bus, a innovative look at storing energy in a flywheel! Mechanical Energy storage baby, and we’re doing a deep dive this week on Two Bit da Vinci!

BAE Systems unveils world’s smallest M-Code military GPS receiver

Posted by in categories: energy, military

BAE Systems unveiled its ultra-small MicroGRAM-M global positioning system (GPS) receiver compatible with next-generation M-Code military GPS signals that are resistant to jamming and spoofing.

According to the defense company, about the size of a postage stamp, MicroGRAM-M is “the world’s smallest, lightest, and most power-efficient M-Code embedded GPS receiver.” The GPS receiver is intended to enable assured positioning, navigation, and timing (PNT) for size-constrained and other micro-applications.

MicroGRAM-M features rapid, secure GPS signal acquisition, enhanced security and resiliency, anti-jamming, and anti-spoofing capabilities. At its heart is a proven, tamper-proof M-Code Common GPS Module that encapsulates classified data and signal processing, according to the manufacturer.

“Liquid Electricity” at a Filling Station Near You?

Posted by in categories: energy, transportation

Dear Reader.

Despite what the mainstream media have been telling you for decades now, the future of consumer and commercial transportation is not electric.

It also won’t be gas-powered…
