The Dutch offshore wind programme is in trouble. While 4.5 GW is in operation and another 1.5 GW under construction, the plan was to rapidly build out capacity to 21 GW by 2032. That is now out of reach.
My thoughts on how this happened, and what to do about it!

Denmark to tackle deepfakes by giving people copyright to their own features
Amendment to law will strengthen protection against digital imitations of people’s identities, government says
The Danish government is to clamp down on the creation and dissemination of AI-generated deepfakes by changing copyright law to ensure that everybody has the right to their own body, facial features and voice.
The Danish government said on Thursday it would strengthen protection against digital imitations of people’s identities with what it believes to be the first law of its kind in Europe. Continue reading...

Sébastien Moitzheim, CTO of @Powall, gave a great talk on continuous production of nanocoated powders at #aldale2025. He showed how to deal with particle mixing & precursor injection. #ALDep at 1bar, not using the high-purity semicon precursors, is a cost-efficient and scalable solution for coating.
