The 1km Colas Wattway Solar Roadway in Normandy in France is finally being scrapped.
Press F in the chat.
€5M of taxpayer money down the drain. That money could have bought a 5MW commercial solar farm that produced 15 times the output power, and lasted decades longer.

An in-depth look at the engineering inside a quantum computer, and also demonstrating the operational results live and how they are measured.
With Professor Andrea Morello who is the Scientia Professor of quantum engineering in the School of Electrical Engineering and Telecommunications at the University of New South Wales, and a Program Manager at the ARC Centre of Excellence for Quantum Computation and Communication Technology.

Previous in-depth discussion on how quantum computers work: https://www.youtube.com/watch?v=jDW9bWSepB0

00:00 - 🔬 Discussing job opportunities and showcases a quantum computer experiment at the Fundamental Quantum Technologies Laboratory in Australia.
7:14 - ❄️ A refrigerator that can cool down to 4° Kelvin using helium gas.
13:23 - 🔬 The design and purpose of a filter box used in low temperature experiments to filter out high frequency signals.
20:11 - 🔬 Research and new science are being done with prototype chips that can stay in a fridge for up to four years.
27:14 - 💡 The video explains how a transistor works and how the movement of electrons can cause a shift in the pattern.
33:36 - Silicon is a practical choice for quantum computing due to its semiconductor properties and isotopic purity.
40:39 - 💡 Magnet quench is when a superconducting wire goes from being a superconductor to a normal resistor, causing a significant amount of power dissipation.
47:41 - 🔬 How a refrigerator is used to cool down the electron electrochemical potential in order to populate the spin down level for magnetic resonance.
54:30 - 🧪 Designing a cancer cure on a classical computer is computationally complex due to the quantum nature of the problem.
1:01:14 - 🔬 A startup has developed a commercial machine for Quantum control that allows users to manipulate and operate a large multi-dimensional Quantum system.
1:07:29 - 🔬 Advantages of using silicon MOSFET over other materials for spin-based operations.
