Drones doing the dirty work, improving precision and safety
At the Juktan hydro power plant in northern Sweden, autonomous drones are revolutionising operations. The drones navigate kilometre-long dark tunnels, ensuring precise documentation and navigation, while improving personnel safety and significantly enhancing accuracy.

The race to decarbonise aviation
From electric planes to biofuels, hydrogen, and electrofuels, the flight industry is charting a more sustainable path forward. Mikael Nordlander, Director of Industry Decarbonisation at Vattenfall, highlights the important role of fossil-free electricity in reducing air-traffic emissions.
Fast charge, loads of cycles
A new lithium metal battery has been developed by scientists at Harvard's John A. Paulson School of Engineering and Applied Sciences (SEAS). Capable of at least 6,000 charge and discharge cycles, this innovation offers rapid recharging capabilities, reaching full charge within minutes – a technology that could transform your daily life by powering electric vehicles that travel further and charge faster, and by boosting the battery life and charging speed of smartphones and laptops.

The balcony boom
Germany has long been one of the leading nations in terms of generating solar power from residential homes, especially rooftop panels. Now, the government is encouraging people to install solar power on their balconies. (euronews.com)
A heat pump revolution
Air conditioning units in the windows of brownstone houses and skyscrapers have been one of the iconic features associated with New York. However, they may soon be replaced by heat pumps. (wired.com)
Final countdown for coal
For much of the 20th century, coal was the United Kingdom's primary source of electricity production. But over the past 20 years, coal power stations have been shut down one by one. Now it is time to say a last goodbye. (theguardian.com)

How footsteps reduce CO2 footprint
Small kinetic movements can have big energy effects, as shown by a pioneering energy project in Paris. A system engineered by students from the Junia Graduate School of Science and Engineering, which converts turnstiles into mini turbines, utilised the movement of 27,000 daily commuters to generate electricity. This technology could potentially reduce Paris's CO2 emissions by 30,000 tons annually.
