Tesla batteries help power new solar water desalination plant in Africa

Posted by in category: sustainability

GivePower has deployed a new water desalination plant in Africa using Tesla batteries and solar power that is now providing clean water to thousands of people.

The system has been deployed in Kiunga, a rural village in Kenya where the lack of clean water had people sometimes rely on saltwater wells or even contaminated water.

Finland ends homelessness and provides shelter for all in need

Posted by in category: habitats

In Finland, the number of homeless people has fallen sharply. The reason: The country applies the “Housing First” concept. Those affected by homelessness receive a small apartment and counselling – without any preconditions. 4 out of 5 people affected thus make their way back into a stable life. And: All this is cheaper than accepting homelessness.

Read this article in German here.

Finland is the only country in Europe where homelessness is in decline.

Ford says reservations for its first-edition electric Mustang are full

Posted by in category: futurism

Ford is no longer taking orders for the first edition of its new electric Mustang, the Mach-E.

The company will still be taking pre-orders for other versions of the crossover, including premium and GT, according to a press release.

Ford unveiled the Mustang Mach-E in November and began taking $500 refundable reservations before the Mach-E makes its debut next year.

V-Coptr Falcon bi-copter has a flight time of 50 minutes

Posted by in categories: drones, robotics/AI

Zero Zero Robotics has publically released its latest product, the V-Coptr Falcon, a v-shaped bi-copter. The drone can achieve a flight time of 50 minutes thanks to its two motors, which are attached via tilting arms. The V-Coptr Falcon also has a 4K 3-axis stabilized camera, obstacle avoidance, and a 7km transmission distance.

On This Day in Space! Dec. 30, 1930: 1st Photo of the Curvature of the Earth

Posted by in category: space

On Dec. 30, 1930, the first-ever photo of the Earth’s curvature was taken.

This photo was taken by Lieutenant Colonel Albert William Stevens, who was an officer in the U.S. Army Air Corps and an aerial photographer. He also happened to be a balloonist, and he once broke a world record for a high-altitude balloon flight. Stevens took this photo while flying in a balloon over South Dakota.

Chip-to-chip quantum teleportation and multi-photon entanglement in silicon

Posted by in categories: computing, quantum physics

Integrated optics provides a versatile platform for quantum information processing and transceiving with photons1,2,3,4,5,6,7,8. The implementation of quantum protocols requires the capability to generate multiple high-quality single photons and process photons with multiple high-fidelity operators9,10,11. However, previous experimental demonstrations were faced by major challenges in realizing sufficiently high-quality multi-photon sources and multi-qubit operators in a single integrated system4,5,6,7,8, and fully chip-based implementations of multi-qubit quantum tasks remain a significant challenge1,2,3. Here, we report the demonstration of chip-to-chip quantum teleportation and genuine multipartite entanglement, the core functionalities in quantum technologies, on silicon-photonic circuitry. Four single photons with high purity and indistinguishablity are produced in an array of microresonator sources, without requiring any spectral filtering. Up to four qubits are processed in a reprogrammable linear-optic quantum circuit that facilitates Bell projection and fusion operation. The generation, processing, transceiving and measurement of multi-photon multi-qubit states are all achieved in micrometre-scale silicon chips, fabricated by the complementary metal–oxide–semiconductor process. Our work lays the groundwork for large-scale integrated photonic quantum technologies for communications and computations.
