There are many directions we could go when it comes to the future of sustainable energy—but the UK made a bold move when it announced a huge investment (220 million pounds huge) in a prototype fusion power facility that could be functioning as a commercial power plant by 2040.

Researchers from the University of Houston have reported a new device that can both efficiently capture solar energy and store it until it is needed, offering promise for applications ranging from power generation to distillation and desalination.

Unlike solar panels and solar cells, which rely on photovoltaic technology for the direct generation of electricity, the hybrid device captures heat from the sun and stores it as thermal energy. It addresses some of the issues that have stalled wider-scale adoption of solar power, suggesting an avenue for using solar energy around-the-clock, despite limited sunlight hours, cloudy days and other constraints.

The work, described in a paper published Wednesday in Joule, combines molecular energy storage and latent heat storage to produce an integrated harvesting and storage device for potential 24/7 operation. The researchers report a harvesting efficiency of 73% at small-scale operation and as high as 90% at large-scale operation.

Heliogen is a startup that wants to “replace fuels with sunlight.” And the Bill Gates-backed solar startup, which has flown under the radar until today, has made a major green-energy breakthrough for heavy industry. Heliogen “has created the world’s first technology that can commercially replace fuels with carbon-free, ultra-high temperature heat from the sun.”

There are different kinds of solar panels. The one most typically used is a type that generates electricity from the sun through a physical process called the photo-voltaic (PV) effect – when light exposure on certain materials generates an electric current. Another type generates electricity from heat through thermal processes – when the sun is hotter and Earth is cooler, and the difference in temperature can be converted into usable energy.

That second kind of solar panel is the one that inspired a team of researchers at Stanford University in Palo Alto, California to develop a new system that can harness energy in darkness. It’s based on the concept of using heat to generate energy but an inverse version of the solar panel. While the solar panel uses the heat difference between the sun and Earth with the Earth being the cooler side – their system makes use of the heat difference between the coolness of the night atmosphere and the Earth with the Earth being the hotter side. The study has been published in the scientific journal Joule.

Study author Shanhui Fan, Stanford electrical engineering professor, told Gizmodo:

Nikola Motor, the Phoenix-based startup that wants to disrupt trucking with futuristic electric semis powered by hydrogen, says it has developed a new type of battery cell with double the energy density, only 40% of the weight and half the cost of current lithium-ion batteries used in Teslas and other consumer-market electric vehicles.

But it’s not providing many details for now, and public demonstrations won’t happen for about 10 months.

Insect farming is a small – but growing – industry globally, with bugs touted as a sustainable and cheap food that is high in protein, vitamins, fibre and minerals. Their cultivation, meanwhile, has much less environmental impact than meat.

With predictions that the insect market could grow significantly, it is not just scientists cooking up ways to put bugs on the menu but also some of the world’s largest food and agricultural companies.

Tesla’s first Gigafactory in Reno, Nevada, has a well-documented place in the company’s history, both for how it helped Elon Musk ship his first mass-market electric car and because production problems there nearly doomed the automaker. But what’s been harder to come by is an account of the impact the factory has had on the town it was built for — until this week, that is. USA Today’s The City podcast spent an episode vividly retelling how Tesla’s first Gigafactory came to Reno with a deep dive into the way it’s changed the city.

Researchers in Sweden have created a molecule that offers a way to trap heat from the sun.
