Concentrated CO2 enables growth spurt in algae

A new technology captures CO2 from ambient air efficiently and inexpensively. Researchers at the University of Twente used the CO2 captured to cultivate algae, but the technology can also be used in a closed cycle to store ...

Battery-less computers can now be reprogrammed wirelessly

Computers are getting better with each day. They are becoming so energy-efficient that we can now think about cutting the final cord that connects them with the outside world: a power supply cable. A great example of such ...

And the beat goes on: The reliable heartbeat of hibernators

At the current temperatures, all hibernators have probably emerged from their winter hibernation and are enjoying the warm weather. However, this is quite different during the cold season. Many small mammals such as marmots, ...

Developing inorganic lead-free perovskite for broadband emission

Artificial lighting accounts for one-fifth of global electricity consumption, and developing efficient and stable luminescence materials is critical to avoid unnecessary waste of electric energy. The single emitters with ...

How ambient energy could power the Internet of things

In the modern world, we are increasingly surrounded by digital sensors, cameras and communications devices sending data cloud-based analysis services. Those devices need power, and designers are finding new ways to draw it ...

A smart faсade that saves energy and reduces bills

Imagine a hot climate in a residential building at noon: the shutters are down. There is no breeze but the air is not stifling. This is possible thanks to a ventilated façade that circulates fresh air saved the previous ...
