Using skyscraper lifts to store energy when there's a surplus and generate it when it's scarce. That's what a team of researchers aims to achieve with a new gravity-based system, details of which have been published in the journal Energy. We analyse the potential and the limitations of this technology.

In the midst of a series of global crises—energy, climate and political—many powers have strengthened their commitment to nuclear energy. Although this type of energy aims to reduce greenhouse gas emissions, it suffers from the same old drawbacks: high costs and the need to manage the radioactive waste. Have we learned to control its risks?

It aims to end its dependence on Russian oil and gas through energy efficiency, renewable energies and diversification of supply.

Revolutionary inventions such as the compact disk, high-definition television and 3D printers have been unveiled at the CES trade show over the past few decades. We analyse the gadgets and technological trends that will likely gain momentum in 2022, according to the announcements made at the latest edition of the biggest technology fair in the world, which has just been held in Las Vegas.
