Google has partnered with Kairos Power and plans to power its data centers with small modular reactors. The aim is to secure 500 MW of zero-emission energy by 2030. The ambitious plan faces both technical and societal challenges.

In a time when the energy demands of data centers and artificial intelligence are rapidly increasing, technology giants are seeking alternative energy sources. Google has taken a bold step by partnering with the startup Kairos Power to build seven small modular reactors to power its data centers. This step promises to add approximately 500 megawatts of zero-emission electricity to the grid.
Google's collaboration with Kairos Power is not unique. Other tech companies like Microsoft and Amazon are also turning to nuclear energy. Microsoft has partnered with Constellation Energy to restart a reactor at Three Mile Island.
Conversely, Amazon plans to establish a hyperscale data center directly connected to a nuclear power plant in Pennsylvania. Thus, nuclear energy is increasingly being seen as a reliable and zero-emission source for energy-intensive data centers.
Kairos Power is among the new generation of startups focused on small modular reactors (SMRs). These reactors promise lower costs and quicker construction compared to traditional nuclear power plants.
Kairos takes it a step further by using molten salts of lithium fluoride and beryllium as coolant instead of water. While the innovative approach has received approval from regulatory bodies, it also represents a technological challenge.
The economic aspect of SMRs has not yet been proven in practice, and the use of molten salts deviates from decades of experience with water-cooled reactors. Public opinion also poses a significant hurdle.
Although support for nuclear energy is growing, there is still a significant portion of the population opposed to its use. Google expects the new plants to be operational by the end of the decade. Kairos Power originally planned to commence commercial operation in the early 2030s, so the 2030 timeframe appears ambitious.
Furthermore, Kairos finds itself in a race with fusion startups that are also aiming to launch commercial plants by 2035. Whether Google and Kairos Power will be able to overcome these obstacles and realize their vision of nuclear-powered data centers remains to be seen.

Connecting to the internet today is not just a matter of speed but also of trust. Networks handle more and more devices, sensitive data, and services that communicate almost constantly. This is why an approach called zero trust has emerged, where nothing is automatically considered safe. The article explains why this model was created and how it subtly influences everyday internet functioning.

It happens that the battery life decreases faster than one would expect, even when the device is not particularly stressed during the day. Often, it's not a single specific error but a sum of small influences that gradually accumulate. This article explains what has the greatest impact on battery life, when idle draining occurs, and why this can turn into an issue causing the phone not to last even one day.

Connecting to the internet during a flight is no longer an exception, but it still doesn't work as you're used to at home. In-flight Wi-Fi depends on the technology used, the type of aircraft, and network congestion, and paying for access doesn't always mean fast connection. In this article, we'll explain how in-flight internet works, why it can be slow, and when you can rely on it.

RCS chat is appearing more frequently in mobile devices, especially with the arrival of iOS 18 and the gradual phasing out of older networks. It is a method of communication that uses the internet, offering higher quality sharing of photos and videos than traditional SMS. We'll explain what RCS means and when it makes sense to keep it enabled.

A first mobile phone can make a child's communication and daily orientation easier, but it also opens topics that are good to address in advance. These include safety, sharing, communication, or screen time. How to prepare a child for their first phone so that they use it safely, calmly, and wisely?

Cities around the world are seeing an increase in autonomous vehicles as part of their transportation systems. However, their reliability varies significantly by region. We will explore where this technology is already commonly transporting passengers and what autonomous driving means in practice today.
