Executive Branch held a launch party that included members of President Donald Trump’s administration as well as wealthy CEOs, tech founders and policy experts.

“Simply put, the United States cannot afford to fall behind, or worse, lose the race entirely.”

The Portuguese grid operator — REN — is out with a diagnosis of what happened with the huge power outage today:

• Due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in very high volatge lines, something called ‘induced atmospheric vibration’
• These osculations cause synchronization failures between the electrical systems
• It’s a complex phenomenon and there is a need to rebalance electricity flows internationally, it could take a week to fix

That’s fascinating.

Here is how DeepSeek explains it:

Induced Atmospheric Vibration (IAV) in high-voltage power lines refers to low-frequency oscillations (typically 0.1–10 Hz) caused by corona discharge effects near the conductors. Here’s a brief breakdown:

1. Cause:

   • When high-voltage lines operate near their corona inception threshold, ionization of surrounding air molecules occurs, creating space charges (ions and electrons).

   • Under
     certain conditions (e.g., high humidity, rough conductor surfaces),
     these charges interact with the electric field, generating periodic electrohydrodynamic (EHD) forces.

2. Mechanism:

   • The EHD forces induce pressure waves in the air, causing vibrations in the conductor or nearby objects (e.g., insulators).

   • Unlike aeolian vibration (caused by wind) or galloping (large-amplitude motion), IAV is driven purely by electrical-atmospheric coupling.

3. Effects:

   • Usually low amplitude but can contribute to fatigue over time.

   • May exacerbate other vibration modes or cause audible hum.

4. Mitigation:

   • Smooth conductor surfaces (e.g., polished or coated wires).

   • Optimized voltage gradients to minimize corona.

IAV
is less common than mechanical vibrations but is studied for its unique
electromechanical interactions. …

The vibrations can lead to fatigue cracks and loosened hardware.

Trump has held up tariffs as a negotiating tool with China and claimed talks are ongoing, but Beijing says so far there have not been any negotiations.

Temu, which sold customers on the ability to “shop like a billionaire” started adding “import charge” to orders in response to Trump’s tariffs on China.

Palo Alto Networks is acquiring Protect AI for an undisclosed sum to strengthen its defenses against emerging AI-driven cyber threats.

The GBPUSD is extended another new high as the stocks move to a close and the day to an end.

The pair is extending above the high from last week at 1.3423. The high off my chart from September 2024 reach 1.34333. The high price to reached 1.34393. That takes the price to the highest level since the week of February 20, 2022. Going back to that time, there is not a lot of resistance until 1.3486, and above that 1.36446.
