The proposed innovation is a sustainable, cost-effective and scalable flow battery that can store excess renewable energy in water (H2O) and table salt (NaCl). I have named this the BlueBattery. It is a combination of two well-established technologies: [1] Electrodialysis (ED), which uses electricity to desalinate water with the help of special ion-exchange membrane. ED produces a stream of concentrated salty water and a stream of freshwater from brackish water. [2] The reverse is also possible. One can perform Reverse Electrodialysis (RED), i.e. mixing salty water with fresh water to produce electrical energy. Renewable energy sources are intermittent; this means that electricity generation using these sources fluctuates. To supply the world with 100% renewable energy, energy storage is indispensable. ...

As it becomes apparent that the COVID-19 virus can be exhaled as an airborne pathogen, it becomes equally important to protect oneself from inhaling the virus in its bioaerosol form.

Proposed is a downdraft visor, the device worn as shown provides a steady downdraft stream of filtered air across the wearer’s face. A rechargeable battery unit powers mini-fans to draw in ambient air through a milli-pore HEPA filtration cartridge directing it downward in front of the wearer’s face.

The constant stream of filtered air directed across the front of the wearer's face at 50ft/min provides sufficient airflow to prevent exhaled aerosolized droplets of the COVID-19 virus entering the user’s airways via the nose and mouth into the lungs.

The device can be ...

What is Electric Vehicle Regenerative Acceleration?

Electric Vehicle Regenerative Acceleration is a new US patented EV innovation that allows electric vehicles to recharge themselves as they drive without the deceleration effects associated with regenerative braking. The innovation accelerates the EV while recharging the vehicles batteries in Regenerative Acceleration Mode and is the exact opposite of regenerative braking.

How does it do that?

Electric Vehicle Regenerative Acceleration introduces a Load Current Delay into generator coil operation which reverses the electric vehicle regenerative braking paradigm.

How long has it been around?

The original discovery was made in 2007, the backing theory was developed at the University of Ottawa from 2007 – 2010.5 and the innovation has been under development since then. 3 US patents have been ...

The recent coronavirus outbreak worldwide created an emergency involving all countries In order to help fight the virus one of the most important early activities is to detect potential carriers through the body temperature monitoring, by individuating those with body temperatures higher than 37.5C.

In order to do a mass screening in short time and at a distance we are proposing the following system:

-A carrier
In our case an unmanned platform, a small airship (15/20mt) that can fly permsnently powered by a PV film to generate solar energy for its electric engines during the day and producing hydrogen for night utilization through a fuel cell system

-A sensor
A powerful infrared sensor, similar to those utilized in airports ...

After reading numerous articles about football helmet design and the comments that "there will never be a concussion-proof football helmet," I am concerned about my grandson who plays high school football. I am also an aerospace materials engineer who does not like the term "never." If we subscribed to the adage that we would "never go to the moon" we wouldn't have much of the technology that we have today.

All of the articles that I have read about football helmet design focus around making the inside of the football helmet energy absorbing and always keeping the outer "shell" hard and rigid. There have been experiments with soft layers over the outer shell but they tend to just relocate ...

Rentable electric scooters are often found in many large city centers and on college campuses for use as environmentally friendly transportation. Unfortunately, The Journal of American Medical Association reported that 40,000 injuries and 29 deaths are related to e-scooter accidents. The safety concern causes many people to fear e-scooters and some cities to ban the use of this valuable mode of transportation.

The Collision Alert Technology for Scooters (CATS) is an “active safety” solution integrated into rental electric scooters. CATS uses sensors and controls to detect potential hazards in the path of the e-scooter. CATS then alerts the e-scooter rider of such hazards so that they can take action to avoid a collision. The CATS solution identifies hazards like ...

Many families across the world use open fires fueled by wood, charcoal or sometimes even plastic as their fire source for cooking, temperature regulation and other reasons. When this is done indoors it can be significantly damaging to health, especially for youth or elderly. For this reason most houses has a chimney or vent for the carbon to get out in the atmosphere. This will add more carbon to the environment that will increase the temperature of the earth on a cumulative standard while making the peoples safe from immediate health risk caused by carbon inhalation. But there are natural balance mechanisms that reduce the amount of carbon from the surrounding like plants but these natural counter balance mechanisms ...

This is a proposal for a green economic development organisation to work alongside counties and allow their communities to develop an ecologically and socially sustainable system for energy, food production and manufacture. It provides increased local resiliency and citizen engagement in response to challenges such as the Covid-19 pandemic, and also minimises carbon emissions to tackle climate change. It is designed to work with a polycentric governance model to include local government, academia, civic society and industry.

Its main goals are: -
1.Organise buildings into renewable energy co-operatives, retrofit buildings as micro-renewable energy nodes and link them in smart distribution/storage grids
2. Build a showcase centre for regenerative productive methods and provide skills training in those methods. Use re-purposed ...

Solid state geothermal energy is right there, under your feet, almost everywhere ... and good news it works when the sun does not shine and the wind does not blow.

Starting with our 2014 Australian Mining PROSPECT Award win for innovative mining solutions, with a drilling system and an incorporated 3D printing capability, the package drills down and tracks heat differentials in rock to supply the required power to be harvested from the specific hole. Every hole drilling is optimised to meet the task in hand, such as the power for smart street lights in co-located power poles, to powering co-located 5G base stations and even 220nM UV LED disinfectant units to clean the air in the same power ...

Here is proposed a new control framework for converters of renewable energy sources, based on choosing their operation mode – grid-forming or grid-following depends on the dynamic properties of a power system. Accordingly with the proposed definition of the power system’s dynamic stiffness (DS) are defining its direct (DDS) and quadrature (QDS) components. The values of these components let us estimate a disturbance’s impact on a power system at bus i, and also the power system’s inertia around bus i at this disturbance. So, using the DS we can estimate the dynamic properties of a power system in real-time, and locally for each need bus. Based on this information, proposed different applications DS for resilience planning at increasing renewable ...
