Milliarden-Grab oder Effizienz-Wunder? Der steinige Weg zur EU-Interoperabilität
Die EU-Kommission verspricht 5 Milliarden Euro Ersparnis pro Jahr durch vernetzte Ämter. Doch ihre erste Bilanz zeigt: Bisher wurde vor allem Papier produziert.

Reservoir thermal energy storage offers efficient cooling for data centers
The rise of artificial intelligence, cloud platforms, and data processing is driving a steady increase in global data center electricity consumption. While running computer servers accounts for the largest share of data center energy use, cooling systems come in second—but a new study by researchers at the National Laboratory of the Rockies (NLR), formerly known as NREL, offers a potential solution to reduce peak energy consumption.

DOGE was never about efficiency.
It was the shotgun marriage of Project 2025 and
“We need something for Elon to do.”
America’s veterans paid the heaviest price for this Frankenstein’s monster,
which spent months clumsily strip-mining the federal government in order to make the rich richer.
Three stories illustrate how DOGE damaged our veterans most of all.
First, the early warning signs:
firing veteran federal employees en masse, pushing GI Bill mortg…

The Greatest Victims of Trump’s Greatest Grift Are America’s Greatest Heroes
The so-called Department of Government Efficiency (DOGE) no longer exists, but its negative impact on veterans will last for decades.

JinkoSolar just shattered the world record for solar cell efficiency, hitting 27.79% with their n-type TOPCon technology—and they're targeting 28% by 2028.
Even more impressive: they achieved 33.84% efficiency with a perovskite-silicon tandem cell. These breakthroughs could be game-changing for renewable energy.

JinkoSolar achieves world record efficiency of 27.79% for TOPCon solar cell
The Chinese manufacturer says Germany’s Institute for Solar Energy Research Hamelin (ISFH) has independently verified the result.

"Theoretisch könnte ein perfekter Verbrennungsmotor […] Wirkungsgrade von deutlich über 60 Prozent erreichen. In der Praxis bleiben selbst modernste Motoren weit darunter."
"Technische Optimierungen wie Turboaufladung [… uvam.] haben die Effizienz in den letzten Jahrzehnten zwar spürbar verbessert – doch die Schallmauer bleibt: Der Carnot-Wirkungsgrad markiert das absolute Maximum, das auch mit noch so viel Ingenieurskunst nicht überschritten werden kann."
