 Quantum Computing

Most people can be forgiven for this one. Gaining a low-level understanding of quantum computing generally requires knowledge of quantum physics which is beyond anyone who hasn’t studied the subject academically!

However, at a higher level, there are also a lot of common misconceptions. Quantum computers aren’t simply computers that are much quicker than regular “classical” computers. In other words, quantum computers won't replace classical computers because they are only better at a narrow range of very specialized jobs. This generally involves solving very specialized mathematical problems which don’t usually come up as day-to-day business computing requirements. These problems include simulating quantum (sub-atomic) systems and optimization problems (finding the best route from A to B, for example, when there are a lot of variables that can change). One area of day-to-day computing where quantum computing might supersede classical computing is encryption – for example, securing communications so they can’t be hacked. Researchers are already working on developing quantum-safe cryptography because there are fears that some of the most advanced cryptographic protection used for security at government level could be trivially defeated by quantum computers in the future. But it won't let you run Windows faster or play Fortnite with better graphics!

Fossil Fuel not dead yet

Fossil Fuel not dead yet “Old energy” will carry most of the load during the early years of the transition, as it guides “new energy” to the pinnacle of global power production. Producing an electric vehicle (EV), for example, requires about twice as much energy as producing an internal combustion engine vehicle. That’s because EVs are essentially batteries on wheels… and batteries are basically just hunks of metal. Mining and processing all of that metal demands a lot of energy. To unearth enough raw ore to produce a  single  midsize EV battery, for example, mining operators must excavate about 250 tons of terrain. After that, they must transport roughly 50 tons of ore to various facilities around the world that can extract the targeted metals and then refine them to battery-grade standards. With a few exceptions, every step of the process consumes some form of fossil fuel. Most other renewable technologies are even more energy-intensive than EVs. Therefore, far from replacing fossil

3D Printing

  3D Printing 3D printing saves time, Cost, and Waste while creating radically new parts.  3D printing is a form of additive manufacturing that builds objects layer-by-layer. 3D printing reduces the time between design and production, moves power to designers and reduce supply chain complexity and at a fraction of the cost of traditional manufacturing. 3D printing will revolutionise manufacturing, privacy, costs and timescales of creating a prototype. Applications include Medical Devices, Testing Devices, Training and Visualization aids, Personal Protective Equipment, Personal Accessories, Emergency Dwellings. 3D printing can be used for prototypes, molds and tools and End-Use Parts. Other 3D opportunities include Hobbies, toys and Games Semiconductors and Semiconductor equipment Die Sets, Jigs and Industrial Molds Foundries and Metal Products Footwear Plastic Products Healthcare equipment and supplies Machinery Automobiles and Auto Parts and Equipment Aerospace This is a massive game

All is flashing in 2023 for a good year

All is flashing in 2023 for a good year The  Breakaway Momentum    indicator compares the number of advancing stocks to the number of declining stocks in the market over a 10-day period. And it’s triggered when the amount of advancing stocks outnumbers declining stocks by about 2-to-1. This is very rare and usually only happens when bear markets are ending and bull markets are starting.   The  Whaley Breadth Thrust  indicator is similar. It compares the number of advancing stocks to the number of declining stocks in the market over a five-day period. And it’s triggered when the amount of advancing stocks outnumbers declining stocks by about 3-to-1. This, too, is very rare and usually only happens when bear markets are ending and bull markets are starting.  The    Triple 70 Thrust  indicator was also triggered. This happens when the percentage of rising stocks in the market exceeds 70% for three consecutive days. This is also a rare indicator, and it also tends to mark the start of a ne
