In a momentous occasion at the Reaching the Last Mile Forum 2023 during the United Nations Climate Change Conference (COP28) in Dubai on December 3, 2023, Bill Gates, the co-founder of Microsoft, delivered a keynote address that marked a pivotal shift towards sustainable energy. This address set the stage for an unprecedented collaboration between Bill Gates’ advanced nuclear reactor company, TerraPower LLC, and the United Arab Emirates’ state-owned nuclear company ENEC. The shared vision between these entities is geared towards exploring and developing advanced reactors, reflecting a collective commitment to expanding nuclear energy capacity globally.
A unique solar reactor promises to overcome the high costs and transport difficulties involved in developing green hydrogen. The first pilot plant will go into operation in Switzerland in February 2024, but the innovation is also attracting interest abroad.
This sobering assessment underscores the urgency of addressing the escalating climate crisis. The revised prognosis from scientists at the Global Carbon Project paints a disconcerting picture, deeming the crossing of the critical 1.5°C global temperature increase threshold as “inevitable” and projecting its consistent exceedance over the coming years.
“We are at the exact location of the future reactor!” exclaims American billionaire Bill Gates, standing in front of a construction site. It is on this site in Kemmerer, Wyoming (United States), that the first mini-nuclear power plant is expected to be operational by 2030. Founded by Bill Gates, the startup TerraPower aims to use sodium to cool these next-generation plants.
Lebanese engineer Raja Yazigi has embarked on a visionary quest to reshape the energy landscape through his revolutionary invention—a solar panel that defies convention by generating electricity not only during the day but also throughout the night.
