Nova Innovation to Develop Tidal Array in Canada

A Scottish energy firm was granted a licence to deploy a tidal array in Canada.
Edinburgh-based Nova Innovation said that the move would lead to 15 new turbines being installed in the Bay of Fundy, Nova Scotia, by 2023.
The project will provide enough electricity to power 600 homes.
In 2016, Nova said that its offshore tidal array at Bluemull Sound off Shetland had become the first in the world to deliver electricity to the grid.

First Liquid Hydrogen Ship Debuts in Japan

The world's first liquefied hydrogen carrier made its debut at a shipyard in Japan, a step towards tapping the carbon-free energy potential of the element. Kawasaki Heavy Industries christened the tanker Suiso Frontier at a ceremony at the Kobe Works yard.
The ship will be used for technology demonstration to establish a hydrogen energy supply chain. The construction is expected to be complete by late 2020.

ISRO Launches Radar Imaging Satellite RISAT-2BR1

In a big boost to India's space-based surveillance, Indian Space Research Organisation (ISRO) successfully launched Radar Imaging Satellite RISAT-2BR1 from Satish Dhawan Space Centre (SDSC) in Andhra Pradesh's Sriharikota. This was PSLV's fiftieth mission. With RISAT-2BR1, PSLV is also carrying nine other commercial foreign satellites from countries such as the US, Italy, Japan and Israel under a commercial contract with New Space India Limited (NSIL). The 628 kg Earth observation satellite is set to be positioned at an orbit of 576km altitude.

'Horse Ridge', Intel's New Chip for Commercial Quantum Computers

Quantum computers aim to carry out tasks in just a few minutes that would take today's best conventional computers thousands of years. But in nearly every photograph of the devices, there's a tangle of wires in the background connected to equipment that controls the quantum computer.
Intel Corp announced a chip that it hopes will change that. The Santa Clara, California-based chipmaker announced a chip called "Horse Ridge" that is designed to take all the work being done by the wires and shrink it down to a chip and electronics about the size of a tea cup saucer.
Quantum computers remain years away from everyday use but have drawn the interest of major technology companies. In October, researchers at Alphabet Inc's Google said they had created a machine that can outpace conventional computers. Other major technology firms such as International Business Machines and Microsoft Corp are also pursuing the technology.

Sustainable New Material for Carbon Dioxide Capture

In a joint research study scientists have developed a new material for capturing carbon dioxide. The new material offers many benefits -- it is sustainable, has a high capture rate, and has low operating costs.
The new material is a bio-based hybrid foam, infused with a high amount of CO2-adsorbing 'zeolites' -- micro porous alumino silicates. This material has been shown to have very promising properties. The porous, open structure of the material gives it a great ability to absorb the carbon dioxide.

SpaceX Delivers Mice, Worms and Robot to Space Station

SpaceX made an early holiday delivery to the International Space Station (ISS), bringing muscle-bound "mighty mice," pest-killing worms and a smart, empathetic robot.
The station commander, Italy's Luca Parmitano, used a large robot arm to grab onto the Dragon three days after its launch from Cape Canaveral.
The two spacecraft soared 420 kilometers above the South Pacific at the time of capture.
It marks the third visit for this recycled Dragon. Flight controllers quickly secured the capsule to the orbiting lab, paving the way for the hatch to open and the unloading to begin. The capsule holds 3 tons (2,720 kilograms) of supplies, including 40 mice for a muscle and bone experiment.
There also are 120,000 roundworms, or nematodes of a beneficial variety that are part of an agricultural study aimed at controlling pests here on Earth.
The capsule also has a large, round robot head with artificial intelligence and the ability to sense astronauts' emotions. Named Cimon, it's an improved version of what flew up in 2018 to be tested as an astronaut's helper.
