The UK’s energy regulator is using a variety of tricks to keep speculative data center projects from plugging into the power grid. The country’s AI ambitions hang in the balance.

Fusion startup Pacific Fusion broke ground on a demonstration facility in New Mexico that it says will generate enough energy to power itself.

Capacity will rise by a record 45GW this year, according to S&P Global Energy.

Tesla's solar roof was an experiment that never really caught on for the company. But does that mean the concept of roof-integrated solar is dead?

Fusion power startup Inertia Enterprises reduced the fuel filling process from a week to just a few hours. It's one of ten hurdles the company must overcome to make a profitable power plant.

Y Combinator alumnus Apollo Atomics is shrinking a key nuclear reactor part, which promises to slash the cost of electricity below natural gas.

TerraPower's nuclear power plant possesses a strategic advantage over competitors, especially when chasing after data center deals.

Companies including Tesla and Base Power are vying for a piece of the rapidly growing market for home batteries. One technology has made it all possible.

This isn't a syntax error or a bug in the query — it's Power Query's Formula Firewall refusing to combine data from more than one source until it knows whether that's actually safe. Combining a private/organizational source with a public one (an internal database and a public web API, for example) can leak data from one into the other; the firewall blocks it by default rather than guessing. Why This Exists Every data source in Power Query has a privacy level — Public, Organizational, or Private — set the first time it's connected to. When a query's steps end up needing to send data from one source into a call against a different source, Power Query checks whether the privacy levels involved allow that combination.

Fusion startups have raised $7.1 billion to date, with the majority of it going to a handful of companies.

Utility-scale solar leads by a mile, followed by batteries. Fossil fuels, not so much.

A massive new gas plant in Texas will be built with much less efficient technology than regular gas plants. It’s far from the only data center power project to rely on dirty turbines.

Tesla wants to build a massive solar factory in Texas, but first it wants the state to chip in to defray the costs.

Fusion power startups are turning to Kyoto Fusioneering to supply components for future power pants. The Japan-based startup just received a grant to build a part of the fuel system.

Looking for Contributors to Build Zentrail IDE — An AI-Native Open Source Desktop IDE Hello everyone! 👋 I'm building Zentrail IDE , an open-source, AI-native desktop IDE designed for the next generation of software development. The goal isn't to build another code editor. The goal is to create an IDE where multiple AI agents can collaborate with developers in a single workspace to plan, write, review, test, and manage code. We're still in the early architecture and planning phase, and I'm looking for developers, designers, and AI enthusiasts who want to help build it from the ground up. 🎯 Project Vision Create an AI-first development environment that combines: 🧠 Multi-Agent Collaboration 💻 Native Desktop Performance 🤖 AI CLI Integration 📦 Plugin & Skill Ecosystem 🌍 Open Source Community ⚡ Modern Developer Experience ✨ Planned Features Workspace System Multi-project workspaces Workspace memory Persistent sessions Task management AI Workspace Agents Multiple AI agents running simultaneously Shared workspace memory Parallel task execution Intelligent task orchestration AI CLI Support Claude Code Gemini CLI OpenAI-compatible providers Local AI models Custom AI CLIs Git Automation AI-assisted commits Pull requests Code reviews Branch management Repository insights Skill System Install reusable AI workflows with a single command.

Base Power’s $1 billion round will help the startup ramp production of its home batteries.

One thing Microsoft is not good at is naming things, and sadly it's happened again. But let's go back to the beginning: what are Skills? Skills are targeted prompts/context that are modular, so they are not always included in the LLM session. They are Markdown files with selected metadata in YAML, all in a file normally named skill.md (the parent folder and YAML metadata identify it). They were created by Anthropic (Claude) and were designed for both the user to add in a prompt ( /Skill ), or for the LLM to decide. Similar to Skills are Plug-ins. These can (and often do) include skill.md files, but can also have scripts, MCP servers, and other tools. So back to Microsoft naming things badly. Copilot Studio (Azure Bot Framework version) had skills, but they were not skills. The new Copilot Studio has Skills, but they are not Skills, they are actually Plug-ins. Plug-ins include Skills, so why does it matter? Well, it doesn't really, but I like to moan, and it means sometimes cool functionality can be left on the table because we presume Microsoft names things accurately. Anyway I digress (I like to do that), now we understand what Skills/Plug-ins are I wanted to dive into them within Copilot Studio and cover: Why Are They Cool Building Powerful Skills Adding Scripts/Templates Using Skills 1. Why Are They Cool I often go on about skills being cool, but why? There are a few reasons. Context Management Before skills, the standard approach was to give the LLM everything and let it figure out what it needed. The problem with this is twofold. First, more context equals more tokens, which equals more cost. Second—and more importantly—too much unrelated context can have a detrimental impact on the LLM response. LLMs work by using input tokens to predict the next token, so polluted input tokens can make the LLM predict the wrong next token (this is a huge simplification, but you get what I mean). Transferable As skills are simple Markdown files, they can easily be transferred

Everything looked perfect. I had mcporter 0.7.3 configured with the Exa MCP server: mcporter list exa # ✅ exa (2 tools) — "Search the web for any topic..." Healthy. Ready. Then I made the first real call: mcporter call "exa.web_search_exa(query: \" ollama cloud models\ ", numResults: 5)" JSON parse error at position 1. Every. Single. Time. I tried every quoting trick known to PowerShell: Backslash escaping --% stop-parsing operator cmd /c wrapper Single-quoted outer strings Same error. The shell was eating my quotes before mcporter ever saw them. This is the full story of how I debugged it, verified on Windows PowerShell 5.1 on July 31, 2026. Chapter 1: The Root Cause - PowerShell 5.1's Dirty Secret PowerShell 5.1 strips ALL embedded double-quotes at the native-argument boundary when passing args to external programs. There is no $PSNativeCommandArgumentPassing in 5.1. That is a PowerShell 7.3+ feature. So this: mcporter call --args '{"query":"test"}' Literally becomes this before Node.js even starts: { query:test } The JSON is destroyed. No shell-level trick can fix it. Stop fighting the shell. Chapter 2: The Hero - A 10-Line Node.js Spawn Wrapper The fix is to bypass the shell entirely with spawn(..., { shell: false }) . Node passes a real argv array, no re-quoting happens. Create mcporter_exa.js : // mcporter_exa.js - The hero const { spawn } = require ( ' node:child_process ' ); const args = process . argv . slice ( 2 ); // --tool <tool> <base64Json> mode, or default web_search_exa const tool = args [ 0 ] === ' --tool ' ? args [ 1 ] : ' exa.web_search_exa ' ; const payload = args [ 0 ] === ' --tool ' ? args [ 2 ] : JSON . stringify ({ query : args [ 0 ], numResults : Number ( args [ 1 ] || 5 ) }); const child = spawn ( process . execPath , [ require . resolve ( ' mcporter/dist/cli.js ' ), ' call ' , tool , ' --args ' , payload ], { shell : false , stdio : ' inherit ' }); child . on ( ' exit ' , ( code ) => process . exit ( code ?? 0 )); Usage: # Web search - que
