Waste Heat Recovery

Does your laptop ever get extremely hot and start to make loud noises as if it’s going to explode? That’s because when we use our devices for too long, it can cause them to overheat and make the problems worse.

This is where waste heat recovery comes to the rescue. Waste heat recovery collects unwanted heat from a product and turns it into energy that can be used elsewhere.

There are many common household appliances that produce waste heat. Dryers, fire heaters, and steam boilers, to name a few. Waste heat recovery reduces the heat from these appliances so they don’t overwork themselves and break down.

According to the U.S. Department of Energy, 50% of energy from burned fuels in the U.S. become waste heat in the atmosphere. With waste heat recovery, we could attain 20% of total domestic electricity demands and reduce greenhouse gas emissions.

HOW ENERGY-HARVESTING INNOVATIONS BENEFIT SOLDIERS

innovations benefitting soldiers

Soldiers depend on the battery life in their electronic devices like radios, GPS systems, night vision goggles while out on a mission. According to Noel Soto, project engineer at the Army Natick Soldier Research, Development, and Engineering Center, studies have shown that 16 to 20 pounds of the heavy loads soldiers carry comes from batteries.

"While the standard resupply mission is currently 72 hours, military operations are becoming increasingly expeditionary -- often with a special-ops focus -- pushing resupply missions out to five or more days," said Edward Plichta, Command, Power and Integration Directorate's Chief Scientist for Power & Energy, under the Communications-Electronics Research, Development and Engineering Center.

To remedy issues like this, the army has been focused on finding alternative ways to power gear. In 2016, the army began testing a device that straps to Soldiers’ legs and generates power just by walking. The device, now called The Power Walk®, is a lightweight energy harvester that generates electricity walking, much like how regenerative braking works in hybrid cars. The harvester’s on-board microprocessors analyze the wearer’s gait to determine when to generate maximum power with the least amount of effort.

Other energy-harvesting innovations, like the Energy Harvester Assault Pack, reuse the energy exerted naturally from Soldiers’ movements. Not only is this reusable energy guaranteed to have a protracted battery life, but it also frees up space in Soldiers’ bags, lightening their loads and allowing more room for necessities like water, food, and ammunition.

The next phase of the energy harvesting development focuses on creating and providing power beyond just charging batteries. Accomplishing this could mean that power can be provided to all Soldier-wearable devices, like the Product Manager Soldier Warrior's NETT Warrior device, through a Soldier power management system.

Valuable innovations like these are created to benefit our Soldiers so they not only have to carry the weight of batteries, but also so they can extend their mission with the same battery. With improvements in technological innovations, the possibilities of helping our Soldiers are endless.

II-VI Marlows’ team of accomplished engineers works hand-in-hand with OEMs to develop optimized thermal solutions. From concept to completion, II-VI Marlow offers state-of-the-art thermoelectric solutions to meet your requirements.

A Growing Thermoelectric Refrigeration Market

Human beings love refrigeration - the ability to store perishable food and medical products in a cold environment for long periods of time has made a huge impact on the progression of our species. Refrigeration technology has made great advances since its inception, but has arguably become stagnant since 2005 when census data showed that 99.5% of American households had a refrigerator. Sure, the devices are becoming more sleek and efficient, but the core technology for cooling has more or less remained the same: pumps and compressors. The latest in technological advances for refrigerators is cooing from thermoelectric coolers (TECs) - these devices do not require a standard compression pumps and are gaining traction to help us build a more energy efficient and eco-friendly world.

Next Gen Technology: Using the Human Body as a Generator

Our wearable devices and wearable technologies have become a part of our everyday lives. From bluetooth airpods to fitbits, wearable technology has become our norm and we don’t leave the house without it. We track our fitness health, read our email, and have it tell us the news as we walk from our cars to work. As innovative as these new wearable technologies are, they have the confines of a battery and we still have to take them off at night and plug them into a charger for tomorrow’s enjoyment. Have you ever considered that your body could become a power source for your favorite wearable devices? It would only be fitting that next generation technology utilizes next generation power.

Next Generation Technology: Generating Electricity from Space

A recent experiment done by researchers from Stanford University in California tries to expand on the viability of adapting solar panel technology to create electricity and energy from the night sky. This study has been documented by Science Alert and offers unique perspectives on identifying another potential source of renewable power. Essentially, researchers were making photodiodes contained in the solar panels “work backwards” in an attempt to generate power from a cold source.
