While Facebook and Google recently pulled the plug on their solar-powered internet drones, another company with a lot more experience is having success with the idea. Airbus announced that its solar-powered Zephyr S HAPS (high altitude pseudo-satellite) flew for 25 straight days, setting a time aloft record for any airplane, ever. It shattered the previous record of 14 days, marked by a previous prototype Zephyr aircraft.

The Zephyr flies on sun power alone at over 70,000 feet, an altitude that just a few aircraft like the Concorde and SR-71 Blackbird have reached. That’s well above any weather, and lets it perform reconnaissance, surveillance and communications/internet duties. “[It fills a] capability gap complimentary to satellites, UAVs and manned aircraft to provide persistent local satellite-like services,” Airbus said in a press release. A video of the takeoff (below) shows that it can be lifted and launched by hand. Once aloft, it can be operated for a fraction the cost of a satellite.

Wealth-generating, flat-pack solar houses and a profit-sharing scheme that incentivises retrofitting are bringing sustainable living to people who would otherwise not be able to afford it.

“One of the biggest problems that we see right now is (the creation of) a big gap between the lower and the middle classes. Everyone is talking about this growing inequality gap,” said Bart Glowacki, co-founder of SOLACE, a start-up based in Warsaw, Poland, set up with the aim of making sustainable housing widely affordable.

Tighter mortgage controls, job insecurity and high student debts in Europe has meant that it is increasingly difficult for young people to buy their own homes.

While Elon Musk owns 20% of Tesla, more than $60 billion would be needed to buy the business from public shareholders.

Saudi Arabia’s sovereign wealth fund is in talks that could see it becoming a significant investor in Tesla as part of Elon Musk’s plan to take the electric car maker private, according to a person with direct knowledge of the fund’s plans.

The Public Investment Fund, which has built up a stake just shy of 5 percent in Tesla in recent months, is exploring how it can be involved in the potential deal, the person said on condition of anonymity. Discussions began before the controversial Aug. 7 tweet by Musk, who is Tesla’s co-founder and chief executive officer, saying he was weighing a plan to take the company private.

If the global population adopted recommended North American dietary guidelines, there wouldn’t be enough land to provide the food required, according to a new study co-authored by University of Guelph researchers.

The researchers found that global adherence to United States Department of Agriculture (USDA) guidelines would require one giga-hectare of additional land—roughly the size of Canada—under current farming practice. Their findings were published in PLOS ONE today.

“The data shows that we would require more land than what we have if we adopt these guidelines. It is unsustainable,” said Prof. Madhur Anand, director of the Global Ecological Change and Sustainability lab where the study was undertaken.

By allowing them to launch higher-power small satellites on smaller rockets, as opposed to the larger, and more expensive rockets that current technology requires.

Made in Space is developing power systems for small satellites that can provide up to 5 kW of solar power and is enabled by the company’s Archinaut on-orbit manufacturing and assembly technology. Current small satellites are typically constrained to 1 kW of power or less.

The production problems Tesla has faced with its Model 3 have been well documented. Now, sources say the company is facing similar issues with its solar roof tile initiative. According to Reuters, former and current employees have revealed that assembly line problems, plus CEO Elon Musk’s exacting aesthetic demands, has delayed production, causing tension with partner Panasonic, and rattling officials that are keen to see a return on significant state investment.

The “Solar Roof,” produced at Tesla’s factory in Buffalo, New York, is designed to look like and function as a regular roof while also generating energy. According to sources, technical challenges have delayed production, as has Musk’s design plans. Speaking to Reuters, one source said that “Aesthetic look is the key point that Elon is not always satisfied with. That’s the big issue.”

Neither Tesla nor Reuters’ sources have revealed current production figures for the roof tiles, but the delays are such that Panasonic — which the initiative depends on for solar components — has been forced to find other buyers for the parts it had built to sell to Tesla. According to a former Panasonic employee, the company has been shipping “large volumes” of its photovoltaic cells as samples to other prospective buyers, due to low demand from Tesla. Panasonic declined to comment on the issue, stating only that it “believes Tesla will use Panasonic cells when it mass-markets the Solar roof.”

This is not sustainable!

Every summer the U.S. Central Plains go dry, leading farmers to tap into groundwater to irrigate sorghum, soy, cotton, wheat and corn and maintain large herds of cattle and hogs. As the heat rises, anxious irrigators gather to discuss whether and how they should adopt more stringent conservation measures.

They know that if they do not conserve, the Ogallala Aquifer, the source of their prosperity, will go dry. The Ogallala, also known as the High Plains Aquifer, is one of the largest underground freshwater sources in the world. It underlies an estimated 174,000 square miles of the Central Plains and holds as much water as Lake Huron. It irrigates portions of eight states, from Wyoming, South Dakota and Nebraska in the north to Colorado, Kansas, Oklahoma, New Mexico and Texas in the south.

We’ve shown that the Tesla Model 3 has the ability to Supercharge quickly already. Just wait until you see the impact of Gen 3 Superchargers.

Europe baked in near-record temperatures on Monday but hopes were for some respite after weeks of non-stop sunshine as people come to terms with what may prove to be the new normal in climate change Europe.

Here is a roundup of recent developments:
