German company Schaeffler has just revealed an innovative new drive system for electric bicycles that eschews traditional bike chains and belts for an entirely electrical-driven system. The new system is known as the Schaeffler Free Drive and marks the entry of one of the most divergent electric bicycle drivetrains we’ve seen in years.

The Free Drive, which was co-developed with electric bicycle drivetrain specialists Heinzmann, is based upon a generator installed at the bike’s bottom bracket.

The rider’s pedaling action powers the generator and converts the energy from mechanical to electrical energy.

The growing interest in deep-space exploration has sparked the need for powerful long-lived rocket systems to drive spacecraft through the cosmos. Scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have now developed a tiny modified version of a plasma-based propulsion system called a Hall thruster that both increases the lifetime of the rocket and produces high power.

The miniaturized system powered by plasma—the state of matter composed of free-floating electrons and , or ions—measures little more than an inch in diameter and eliminates the walls around the plasma propellent to create innovative thruster configurations. Among these innovations are the cylindrical Hall thruster, first proposed and studied at PPPL, and a fully wall-less Hall thruster. Both configurations reduce channel erosion caused by plasma-wall interactions that limit the thruster lifetime—a key problem for conventional annular, or ring-shaped, Hall thrusters and especially for miniaturized low-power thrusters for applications on small satellites.

With hundreds of times more food per acre than regular farms.

Vertical farming is a revolutionary form of agriculture. As its name suggests, it’s a form of agriculture that is specifically designed to facilitate agricultural production inside vertical structures. These farms can be created inside old warehouses, used shipping containers, greenhouses, or other buildings, saving space and energy.

As a more sustainable method of farming, vertical farming tends to require much less energy than regular farming which is estimated to be 95% less water since the used water in farming can be recycled and reused.

Syngas is an important feedstock for modern chemical industries and can be directly used as fuel. Carbon monoxide (CO) is its main component. Direct conversion of widespread renewable biomass resources into CO can help to achieve sustainable development.

Conventionally, bio-syngas is mainly produced through thermal-chemical processes such as pyrolysis, steam reforming or aqueous reforming, which require high temperature and consume a lot of energy.

Recently, a research team led by Prof. Wang Feng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences, in collaboration with Prof. Wang Min from Dalian University of Technology, developed a new method to directly convert bio-polyols into CO.

After centuries of failure, there is finally a way to use solar power to desalinate salty water, produce pure water for home and farm use and have housing in the raw desert.

The key energy driver is the Suns River desalination modules linked with Aquastill’s Membrane distillation – the process in which pure water is separated from contaminated water (salt water, for example) by means of evaporation through a membrane. The combination of Suns River and Aquastill brings productivity up to 50 liters/m2 or the equivalent of 6 times the solar energy input.

The venture is currently in the design phase to expand the 400 square meter demonstration site to produce 80 Cubic meters of pure water per day, expanding food production by 100 times. The site is off the electric grid and uses only solar and wind energy, meaning it has a zero carbon footprint. The demonstration site has been in operation for over two years.

Clean energy sources generated a record 834 billion kilowatt hours (kWh) of electricity, or about 21% of all electricity generated in the US in 2020, the US Energy Information Administration (EIA) reported yesterday. That includes wind, hydroelectric, solar, biomass, and geothermal.

Whether or not a $15 million gift is truly equivalent to $1 billion is up for debate, but there is no doubt that Scott is single handedly upending the model of how billionaires give away fortunes while supporting causes that look to disrupt the status quo and promote social justice. She is also questioning the system that put her into this position of power. “We are all attempting to give away a fortune that was enabled by systems in need of change,” she said this summer.

The third richest woman on the planet, MacKenzie Scott (Jeff Bezos’s ex-wife) is using her vast fortune to revolutionize the world of philanthropy and challenge what she says is the massive accumulation of wealth that’s been concentrated in too few hands.

Less than a week before the Christmas holiday, French IT services company Inetum Group was hit by a ransomware attack that had a limited impact on the business and its customers.

Inetum is active in more than 26 countries, providing digital services to companies in various sectors: aerospace and defense, banking, automotive, energy and utilities, healthcare, insurance, retail, public sector, transportation, telecom and media.

It burns about half the fuel of the same-sized rotorcraft.

In 1989, Vox conceptualized fixed-wing vertical take-off and landing airframes (VTOL), along with a plethora of sketches that looked straight out of a sci-fi movie, for a way to innovate the idea. Several prototypes and component tests later, the aircraft is in its final stages of assembly, and testing is expected to start next year.

Revolving around the concept of increasing the safety and convenience of the passenger, this hybrid aircraft can also fly three times faster than a helicopter.

“Our aircraft can travel at turboprop speeds and land on nearly any helipad in the world,” Brian Morgan, the COO and EVP of engineering at Vox, told Robb Report. “Like any helicopter, it provides the flexibility and ease of point-to-point travel, but at two to three times the speed, with more comfort and the ability to fly above the weather, all while burning about half the fuel of the same-sized rotorcraft performing the same mission,” he said.
