Engineers Develop “Iron Man” Suits – Coming to Factory Floors


Full-body exoskeletons will give workers super strength. What’s the most important things for people to know about the full-body exoskeleton, which can turn an assembly-line worker into a superhero?   Engineers have been working on this wearable robotics technology since 2000, when engineers began cobbling together experimental super-soldier suits for the U.S. Military. A 2010 prototype, which enabled the wearer to punch through wooden boards, earned the nickname “Iron-Man Suit” in the homage to the high-tech gear in the eponymous comic book and movies. But that bulky version kept the user tethered to the [...]

Mechanical Engineers Say Proper Ventilation is Crucial for Your Small Business


Engineers Explain How Good Ventilation Helps Your Business We’ll start with a fact that often startles people: (indoor air quality is a major health threat in the country).  According to the U.S. Environmental Protection Agency, the air quality inside buildings is often 3 to 4 times worse than the air outside. This goes against what most people think air pollution is like— fumes from cars and smoke stacks casting dark clouds over cities.  Heavy wall insulation, tightly fitted, non-opening windows ( Window Efficiency ), and commercial synthetic carpeting in modern buildings allows for the [...]

Engineers Develop Ways to Ventilate Your Home


Why ventilate? For centuries homes weren’t ventilated, and they did all right, didn’t they? Why do we need to go to all this effort (and often considerable expense) to ventilate houses today?  Engineers have developed several reasons that ventilation is more important today than it was long ago. Most importantly, houses 100 years ago were leaky. Usually they didn’t have insulation in the walls, so fresh air could easily enter through all the gaps, cracks, and holes in the building envelope., the building materials used 100 years ago were mostly natural [...]

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, [...]

Engineers Test “CHP” – Combined Heat and Power


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 [...]

Electric Vehicle Batteries: Recycled


  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 [...]

Semiconductor Worldwide: Samsung Takes Over


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 [...]

Window Energy Efficiency: Solar Heat Gain and Visible Transmittance


Conduction and Radiation of Thermal Energy In my last blog post, I wrote about the conduction and radiation of thermal energy through windows and the thermal transmittance value, called the U-Factor, that characterizes that heat transfer.  The U-factor is useful in evaluating window performance and making wise decisions when specifying components for a building, but it is only one piece of the puzzle.  The National Fenestration Research Council (NFRC) mandates a second value alongside U-factor in its certification process, called the Solar Heat Gain Coefficient (SHGC).  SHGC [...]

Window Energy Efficiency: Thermal Transmittance


Figure 1: Windows catching sunlight By Magda S [ Content License] In our last blog post, I wrote about the thermal resistance (R-value) and transmittance (U-factor) of insulation and windows.  The R-value represents how well a material prevents heat transfer through its thickness, and U-factor is its inverse, representing how much heat a material will conduct through.  These values are fairly simple to calculate for most building materials materials like the bricks and panels in Figure 1, as they primarily experience only conductive heat transfer.  Windows are a more [...]

Energy Efficiency in Building Materials, Insulation and Windows


Figure 1: FLIR image of two houses showing energy loss. Colors towards red on the scale indicate warmer surfaces and more energy loss. The basic principle behind thermal insulation is simple to understand.  The harder it is for heat to travel through a material, the better insulator that material will make.  In this blog, I’m going to take a look at how that effectiveness is quantified, after a brief review of the three methods of heat transfer.  The building and construction industry use a ratio called the R-factor to indicate how well [...]

Thermal Expansion in a Glass and Aluminum Window: Part 2


Figure 1: Simplified model of an aluminum-glass window   In last week’s blog, Thermal Expansion in a Glass and Aluminum Window: Part 1, we introduced the basic concept of thermal expansion in solid materials.  Since CTE mismatch can impose extremely high stress, during mechanical engineering design one must consider the temperature exposure and expansion or contraction of a material.  In order to help the read gain insight, we used a simplified aluminum-framed window to demonstrate that a hot summer day would be enough to shatter glass [...]
