Scientists have developed a novel system that recovers energy normally lost in industrial processes.

Each year, energy that equates to billions of barrels of oil is wasted as heat lost from machines and industrial processes. Recovering this energy could reduce energy costs. Scientists from Australia and Malaysia have developed a novel system that is designed to maximize such recovery.

Heat can be converted to electricity by devices called thermoelectric power generators (TEGs), which are made of thermoelectric materials that generate electricity when heat passes through them. Previous studies have attempted to use TEGs to recover energy from the heat generated by, for example, car engines, woodstoves and refrigerators. However, TEGs can only convert a small amount of the heat supplied to them, and the rest is emitted as heat from their “cold” side. No previous studies have attempted to recover energy from the waste heat that has already passed through TEGs. Researchers from Malaysia’s Universiti Teknologi MARA and RMIT University in Australia set out to develop a system that can do this.

Mercedes-Benz has unveiled a rugged new EQC 4×4 electric off-road SUV to show that electric vehicles can also be adventure vehicles.

That’s actually very much Rivian’s mission with the R1T electric pickup truck and R1S SUV, which it describes as “adventure vehicles.”

As for Mercedes-Benz, instead of making a new vehicle, they decided to modify their existing EQC electric SUV.

My hero my love.

Last week, Tesla CEO Elon Musk made a rather interesting announcement for all-electric vehicle enthusiasts in India, when he mentioned that Tesla is planning on entering the Indian automobile market in 2021. The announcement comes after years of waiting for the Indians to get their hands on a Tesla, and it definitely has got the public buzzing with excitement. Now, Musk has also stated that Tesla will be coming up with a Booking Order Configurator for the Indian customers which will be going live in January 2021.

Elon Musk is among the few people on Earth that are working towards changing the course of humanity’s future in a drastic way. He founded SpaceX in 2002 to make life multiplanetary –colonize Mars. Since then, SpaceX has developed some of the world’s most advanced rockets and spacecraft. Throughout the years Musk’s bold ideas, ambitious goals, and ability to lead teams to achieve greatness has earned him a place in history. Hollywood actor Channing Tatum seems to be inspired by Musk’s space venture that he is now planning to produce an HBO drama television series about Musk and his journey at SpaceX.

According to Deadline reporters, who first reported the news, Tatum’s film production company, Free Association, will produce a six-episode scripted series. The story will be about how SpaceX started with a rocket that almost did not make it to orbit, to returning human spaceflight capabilites to the United States. “The project will be penned by Star Trek Beyond scribe Doug Jung based on Ashlee Vance’s book Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future, first published in 2017,” Deadline reports, “Free Association’s Tatum, Reid Carolin and Peter Kiernan will executive produce with Vance and Len Amato, HBO’s former President Of HBO Films, Miniseries & Cinemax.”

The world’s small-scale farmers now can see a path to solving global hunger over the next decade, with solutions—such as adopting climate-resilient crops through improving extension services—all culled rapidly via artificial intelligence from more than 500,000 scientific research articles.

The results are synthesized in 10 new research papers—authored by 77 scientists, researchers and librarians in 23 countries—as part of Ceres2030: Sustainable Solutions to End Hunger. The project is headquartered at Cornell University, with partners from the International Food Policy Research Institute (IFPRI) and the International Institute for Sustainable Development (IISD).

The papers were published concurrently on Oct. 12 in four journals— Nature Plants, Nature Sustainability, Nature Machine Intelligence and Nature Food —and assembled in a comprehensive package online: Sustainable Solutions to End Hunger.

The combination of rooftop and utility scale solar met 100 per cent of demand in South Australia for the first time on Sunday, reaching a milestone that will surely be repeated many times over – and for longer periods – in the future.

The milestone was reached at 12.05pm grid time (Australian eastern standard time), with rooftop solar providing 992MW, or 76.3 per cent of state demand, and utility scale solar providing a further 315MW – meaning all three of the state’s big solar farms, Bungala 1m Bungala 2 and Tailem Bend were operating at full capacity.

Huanghe Hydropower Development has connected a 2.2 GW solar plant to the grid in the desert in China’s remote Qinghai province. The project is backed by 202.8 MW/MWh of storage.

Chinese state-owned utility Huanghe Hydropower Development has finished building the world’s largest solar power project in a desert in the northwestern Chinese province of Qinghai.

Chinese inverter manufacturer Sungrow, which supplied the inverters, said that the 2.2 GW solar plant was built in five phases. It involved an investment of RMB15.04 billion ($2.2 billion) and includes 202.8 MW/MWh of storage capacity. The company announced the storage system as a solar+storage project in mid-May, but at the time it did not reveal that it was to be connected to a giant solar plant.

Circa 2018

In the 2015 movie “The Martian,” astronaut Mark Watney survives on Mars by growing potato plants in his own waste. The scenario is fictional, of course, but it underscores a real-world challenge for NASA: How can the space agency ensure an uninterrupted supply of safe, nutritious food for astronauts who are tens of millions of miles from the nearest supermarket?

The successful launch of SpaceX’s Falcon Heavy rocket marked a big step toward developing the technology needed to transport colonists to Mars, though the strategy for keeping them and deep-space astronauts fed remains a work in progress.

At Pennsylvania State University, researchers think they’ve hit upon a solution. They’ve devised a compact recycling system that uses astronaut poop and pee to fuel the growth of edible bacteria. As described in a paper published in November 2017 in Life Sciences in Space Research, the bioreactor breaks down human waste into salts and methane gas; the latter is used to fuel the growth of a protein-rich “microbial goo” that’s similar in consistency to Vegemite.
