Eviation, which has been described as the “Tesla of aircraft” for working on the first compelling long-range electric aircraft, has unveiled the production version of its Alice aircraft.

It has a shorter range than previously announced.

After Eviation unveiled the prototype of its Alice aircraft back in 2017, the company attracted a lot of attention and comparison with Tesla because the aircraft was amongst the first all-electric plane that was viable for actual commercial use.

UC Santa Cruz is investigating this method as a possible generator of solar energy that would allow for the saving of 63.5 billion gallons of water from evaporation annually, a massive windfall for a state that sometimes rations water and which regularly suffers from droughts.

If mounted above irrigation canals, the shade of solar panels would reduce evaporation by 63 billion gallons, while generating clean energy.

The world’s animals and wildlife are becoming extinct at a greater rate than at any time in human history. Could technology help to save threatened species?

A device that can generate electricity while desalinating seawater has been developed by researchers in Saudi Arabia and China, who claim that their new system is highly efficient at performing both tasks. The device uses waste heat from the solar cell for desalination, thereby cooling the solar cell. It also produces no concentrated brine as waste, cutting its potential environmental impact.

In many parts of the world, climate change and population growth are putting huge demands on freshwater supplies. In some coastal regions, desalination – removing the salt from brackish water or seawater to turn it into fresh water – is increasingly being used to meet demand. Indeed, there are now around 16000 desalination plants around the world producing about 95 million cubic metres of freshwater every day.

Elon Musk and Jeff Bezos have been feuding publicly for years, but the Tesla chief recently came out in praise of the Amazon boss.

The researchers were inspired by bone and cartilage when designing the new membrane.

You’ve likely heard of solar energy, but what is osmotic energy?

Researchers have created an unusual new alloy made up of not two, but five different metals, and put it to work as a catalyst. The new material is two-dimensional, and was able to convert carbon dioxide into carbon monoxide effectively, potentially helping to turn the greenhouse gas into fuels.

The new alloy belongs to a class of materials called transition metal dichalcogenides (TMDCs), which are, as the name suggests, made up of combinations of transition metals and chalcogens. Extremely thin films of TMDCs have recently shown promise in a range of electronic and optical devices, but researchers on the new study wondered if they could also be used as catalysts for chemical reactions.

The thinking goes that because reactions occur on the surface of a catalyst, materials with high surface areas will be more effective catalysts. And as sheets only a few atoms thick, TMDCs are almost nothing but surface area.
