Islandwide blackout hits Cuba as it struggles with energy crisis

Officials in Cuba report an islandwide blackout in the country of some 11 million people as its energy and economic crises deepen. The Ministry of Energy and Mines notes a “complete disconnection” of the country’s electrical system and says it is investigating. Cuban President Miguel Díaz-Canel on Friday warned that the island had not received oil shipments in more than three months and that it was operating on solar power, natural gas and thermoelectric plants. Cuba has blamed its woes on a U.S. energy blockade. U.S. President Donald Trump warned in January of tariffs on any country that would sell or provide oil to the island.

🔄 The Peltier Effect: When electricity moves heat

In 1834, Jean‑Charles Peltier discovered an electric current could make one junction cool while another warms. This thermoelectric effect powers portable coolers, stabilizes lasers, and regulates spacecraft instruments, all without moving parts.

👀 Ah, the age-old tale of #lasers and #thermoelectric generators—because obviously, what clean energy needed was a 15-fold increase in jargon and buzzwords. 🚀 Apparently, all it took was some femtosecond laser magic and a healthy dose of thermal management—because who knew solar power wasn't just about sunshine and rainbows? 🌞✨

15-Fold increase in solar thermoelectric generator performance through femtosecond-laser spectral engineering and thermal management - Light: Science & Applications

A spectral engineering and thermal management strategy is developed to significantly increase STEG power generation. It consists of a fs-laser-treated W-SSA, a greenhouse chamber, and a fs-laser-treated μ-dissipator.
