What is an Axial Flux Motor? To skip to the patent data click here. An axial flux motor is an electromagnet based motor technology that uses pulses of electromagnetic charge to create a rotating force . Axial flux motors are great because they avoid the use of a drive-train altogether. The problem with a drive-train is that it includes a drive-shaft, crankshaft, propeller shaft, and transmission (gearbox). These components connect together and when working use the kinetic pressure between themselves to transfer power as torque. However, the connections cause friction and this friction between components results in a loss of energy. If you look at the image of the gearbox below, you can see how complex and exact the contact surfaces are, but there is still energy loss at each of those contact points. A traditional automotive drive-train is inefficient due to the transfer of kinetic…

The Goal of Reducing Climate Change The OECD advisory on climate change (Green Grown Studies) states that a multi-pronged approach is required to reduce, stop, or reverse climate change. The critical stages in the energy lifecycle that need to be addressed include: Energy generation Transportation Conversion Storage Consumption Smart-grid technology Smart-homes Smart Manufacturing Smart circuits and computer chips Of all the green / renewable sources of power, nuclear fusion has the biggest potential impact. Nuclear fusion is the holy grail of renewable green energy sources and has the potential to drastically reduce CO2 output by replacing other fossil fuels such as coal-fired electricity plants. Other potential sources of renewable power such as solar, wind, geothermal, and hydro offer benefits over non-renewable power such as coal, and oil and gas, but none have the potential to output as much clean energy as realizing commercial of nuclear fusion. However, a future global…

This short introduction to cyber-security covers fundamental concepts. These concepts are the basis for all other cyber-security topics. If you are studying for CompTIA Security+ SY0-501 Exam this a good first video to watch.
General Details SolarWinds is a publicly traded company worth $5.4B dollars that developing IT infrastructure management software products for small and medium-sized enterprises. Two separate pieces of malware known as SUPERNOVA and SUNBURST worked against vulnerabilities in SolarWind’s product Orion. The malware known as SUNBURST potentially allows an attacker to compromise the server on which the Orion products run. The manner in which SUNBURST malware was used against its victims resulted in it being labelled a “supply chain attack,” a technique in which an adversary uses malware to disrupt a companies ability to produce or deliver it’s products to customers. Although the term “supply chain attack” a broad term without a universally agreed upon definition, theoretically, the intended target of a supply chain attack is not necessarily the company whose network was breached and disrupted. For example, if an attacker wanted to disrupt operations of a large retail target such…
In a previous article the impact of cyber-breach on stock prices and the value of cyber-insurance to corporations was reviewed. Ransomware and IT breaches are increasing, and the expectation is that more companies will turn to cyber-insurance, and also increase their IT security controls. Here is a list of cyber-security listed ETFs and a list of all the companies included in those ETFs with duplicates removed, along with a company description. CIBR – First Trust Nasdaq Cybersecurity ETF Includes 40 individual stocks comprising $3.58 billion in assets Includes other industries, such as aerospace and defense (FactSet) Concentrated with 10 largest making up 47% of market cap Two stars rating by Morningstar HACK – ETFMG Prime Cyber Security ETF Includes 59 individual stocks comprising $2.04 billion in assets Modified equal-weight scheme (not concentrated) with 10 largest making up 28.5% of the market cap HACK has “a unique, cybersecurity-focused take on the…
Tale of the Tape Hackers have kicked some big time ass against major American companies in the past 10 years. JP Morgan Chase, Capital One, Equifax, Uber, LinkedIn, eBay are just a few of the large corporate victims. Just in 2021 many corporate IT hacks have made the headlines with the Colonial Pipeline hack being the most recent. Well, that was, until JBS a major American meat processing plant revealed it had also been breached just days ago. Colonial Pipeline CEO confirmed the company paid $4.4 million ransom. CNA Financial, one of the largest insurance companies in the US, reportedly paid hackers $40 million after a ransomware attack. Information on whether Acer ended up paying the ransom for their breach in March 2021 seems hard to come by but, the initial ransom demand was $50 million and included a threat to increase the demand to $100 million. If Acer did…
The LockPicking Lawyer on Youtube is a highly skilled locker picking professional. His videos sure to amaze and are a wealth of knowledge to pentesters looking for physical penetration testing attacks. However, not all of his videos attack the keyway with a set of picks. His videos that use other technology to bypass locks and security devices tell a very interesting tale about the state of the art of technology. I have included some of his videos with a brief description, all of which demonstrate different aspects of lock bypassing. In the first video, you see a new device on the market which is specially designed to take images of the inside of a Kwikset Smartkey keyway. The product is from a company called LockTech LTKSD, and costs about $350 USD. The implication is that this could be used to quickly build a physical key that can work with a…
Privacy Protection From Big Brother (Google and Other Corporations) Google wants to know whether you change your underwear everyday. It’s that simple. They want to know everything about you. Part of your online security is not letting Google or others know everything about you. Why you may ask? Because they can sell that information to employers who want to conduct a background investigations, serve you targeted ads enticing you, and who knows what else. While arguably this generates revenue to improve their products and services, it can also be considered an invasion of your privacy. Individuals involved in activism, or other activities may have their physical security put be at risk (such as police informants).
