Material Engineers : A Pipedream?  Solar-powered cars have been thought of by many as an impossible pipedream. But the innovators behind, a fully solar-powered vehicle to be released in 2019.  GOING FULLY SOLAR A Car whose ability to use solar power has been thought of as an impossible feat.  Designed by the Dutch startup Lightyear, the “car that charges itself” can supposedly drive for months without charging and has a 400 – 800 km range. But is a solar-powered car feasible?Up until now fully solar-powered cars were not considered a realistic prospect, Solar Assisted Electric Vehicles (SAEVs) were considered the best possible option for solar cars, adding up to hundreds of miles to a cars range. But the Dutch Lightyear promises [...]

Engineers Test “CHP” – Combined Heat and Power

2018-09-04T12:40:22+00:00

Figure 1. Self Sufficient Home with Combined Heat and Power Combined Heat and Power (CHP) Engineers combined heat and power (CHP) systems, also known as cogeneration, generate electricity and useful thermal energy in a single, integrated system. CHP is not a technology, but an approach to applying technologies. Heat that is normally wasted in conventional power generation is recovered as useful energy, which avoids the losses that would otherwise be incurred from separate generation of heat and power. While the conventional method of producing usable heat and power separately has a typical combined efficiency of 45 percent, CHP systems can operate at levels as high as 80 percent. Some micro-CHP technologies use mechanical engines, such as internal combustion [...]

Material Engineers : Pros and Cons of Solar Powered Cars

2018-07-25T09:17:33+00:00

Figure 1.  Solar Powered Cars in the Future Although a solar power car may not be commercially viable right now, there are ways that solar power can be added to existing designs to make vehicles more efficient. Material Scientist examine the pros and cons of this technology, it can continue to move forward in development to help save on fossil fuels, and the electric grid and pollutions. Solar-powered vehicles (Solar Cells ) have zero emission level, as they don’t utilize non-renewable resources and burn fuel. The electric motors generate electricity (See Figure 1.) that doesn't emit any greenhouse gases or any other pollutants. These cars are quieter than the vehicles powered by conventional fuels, which don't cause noise pollution as well. Lets [...]

Electric Vehicle Batteries: Recycled

2018-07-18T14:04:45+00:00

  Material Scientist Ponder What to Do With Used EV Batteries  As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025.  This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements.  The price of cobalt has already risen by more than 80 per cent in 2018.   Most expert Material Scientists agree that a replacement hybrid car battery can range from $1,000 to more than $6,000.  The [...]

Engineering Advances: Degradation and Saving Electric Vehicle Batteries

2018-07-10T15:47:30+00:00

Degradation of EV Lithium Batteries  Battery degradation in Electric Vehicles (See Figure 1. to Right) leads to capacity fade, thereby shortening the vehicle’s possible range.  Patterns are beginning to emerge and provide valuable insight into EV battery capacity and lifetime.  Most drivers are retaining over 90% of original capacity Range Anxiety Some cars have a range of only 106 miles, equivalent to just over three times the average daily drive in the US. New Electric Vehicles are expected to have a range of up to 235 miles, a 220% increase, therefore, range is constantly improving to address consumer concerns. Charging an EV takes time, and unless you have fast in-home charging infrastructure or public charging infrastructure it will remain a barrier. [...]

NAND Flash – 11 Myths Still Floating Around

2018-06-27T16:21:57+00:00

Think You Know NAND Flash?  NAND flash has become the de facto memory standard in the years since Toshiba first introduced it almost three decades ago. However, many misconceptions remain to this day about its use. A wide variety of NAND flash-memory products are available, all with significantly different features and capabilities.    All NAND flash has the same interface. NAND flash, introduced by Toshiba more than 20 years ago, is available in both the asynchronous and toggle-mode interfaces. The original asynchronous interface is found mostly in lower-density devices (<32 Gb), while high-density NAND flash (≥64 Gb) is typically used in the toggle-mode interface.( http://glewengineering.com/tester-prober-interfaces-direct-probe-part-1/  UFS memory is primarily just for smartphones. Universal Flash Storage (UFS), while smartphones [...]

Semiconductor Worldwide: Samsung Takes Over

2018-06-22T11:44:20+00:00

Samsung topples Intel as top dog semiconductor market share  Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category.  DRAM prices rose 44 per cent from 2016 to 2017, and NAND flash prices went up 17 per cent year-over-year for the first time. (See Figure Below)   A Gartner table provides the numeric nitty-gritty [...]

Flat Panel and LCD Screens: Part 1

2018-02-13T16:36:45+00:00

Liquid crystal display (LCD) screens are omnipresent in our technologically saturated lives.  Having largely displaced the older CRT screens, LCDs make up a large portion of the digital imaging we see all around us.  They are present in everything from our ubiquitous smartphones and computer screens to digital billboards, wristwatches and vehicle and aircraft instrumentation.  How do flat panel LCD screens work? One can often find videos and articles documenting eager teardowns of new devices, but few delve beyond the hardware and into the materials and design behind the screen itself.  For this series of blog posts, we will be review some aspects of display technology , why they work, and how they are assembled.  To illustrate my points, I’ve disassembled a legacy Sony Ericsson® S500i phone [...]
