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. ...

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 ...

Water is very critical for survival and that is why you hear often on water saving awareness and researches that could help on saving water from big consumption to small consumption in households. The problem of water wastage is not because of awareness because people know when they waste water, they just do not have a habit of saving them. One of the places where water is wasted big time is in household activities like washing your dishes, your hands, brushing your teeth and other similar activities that require us to use the sink multiple times in a very few period of time. On average, about two gallons of water flow from a faucet each minute. Something as simple ...

Ever since the invention of electric power by Serbian-American inventor Tesla Nikola, electric power has been very critical for survival of human beings. Whether the source of the electric power supply is renewable or nonrenewable, you often hear the concept on the awareness of conservation of electric power or electric power saving and researches that could save electric power consumption. One of the places where electric power is wasted is at household level activities like overcharging your devices of any kind. Householders waste £134million a year overcharging gadgets such as mobile phones and laptop computers, according to a study in the UK. One in five Britons leave their devices plugged in once the battery is full because they are ...

Pivot Materials manufactures bio-materials by using agri-waste into plastics and bio polymer. We have reduced the use of plastics from 10% to 100%. Our materials are used in Shipping Pallets, One-time use Disposables, Automotive, Packaging, and Housewares. Some of our initial projects have shown the CO2 reduction up 20% per part.

Our materials are sustainable, cost competitive and no special equipment is ...

A green means of generating electricity from the pitter patter of falling rain drops and sunshine is described here. A falling rain drop strikes at least one piezoelectric element (coated with multi-layer photovoltaic flexible thin films) of a micro-grid array comprised of many piezoelectric elements. The rain drop imparts its momentum from falling to the struck coated piezoelectric element(s) through its flexible coating converting the rain drop's kinetic energy to electricity. When a piezoelectric crystal is squeezed, deformed, compressed, bent, or struck, it generates electricity via the piezoelectric effect. The piezoelectric element can be a crystal, a ceramic, PZT, a plate, a wafer, scintered crystal mixture multi-layer sandwich, a stack, or a film. Each element is coated on top ...

Waveco's Subwave solution is based on an invention patented in 2016 by Inge Bakke, the founder of Waveco. The Subwave turbine is hanging vertically about 100 meters under a buoy floating on the surface. When the buoy is affected by ocean waves, the turbine will alternately be lifted and sinking in the calm and dark water below the wave base, forcing the wings to exert torque on the rotors and generate electricity.

The solution has some important features:
• The energy conversion system will be far below the active wave-zone; hence it does not need to be designed for extreme waves.
• The surface buoy will be a very simple and robust structure that is easy to ...
