According to https://thewaterproject.org/water-crisis/water-in-crisis-ethiopia, Ethiopia is located in Africa's Horn where drought and politics are two leading causes of water shortage. In a study conducted by Water.org, they found that "42% of the population has access to clean water supply" and only "11% of that number has access to adequate sanitation services". In rural areas of the country, these figures drop even lower, resulting in health problems in the villagers as well as their animals. There is a lack of water in Ethiopia and the Horn of Africa. There can be many reasons but the most common one is wastage. This design solves the major water wastage of car wash service. As seen in the attached pictures, the common car ...

The presented Idea is based on heat exchange principle. It will work in this way that the temperature of the machine or electronic device will be not increased. As per the sketch there will be a conveyor belt system and copper stripes will be connected with this belt.

Each copper strip will have a moveable hook.

The conveyor belt will move with two motors.

Each copper strip will be separated with each other and with conveyor belt with the help of Insulation.

How this idea will work?

The idea is very simple.when the copper stripe will be connected with the machine for Five to ten seconds then it will work to absorb the heat and after that this copper ...

Companies have understood the advantage of recycling and most companies in the world are investing to recycle their products. There are many factors why a company is interested or not interested in recycling their product. But the most critical factor is cost. Is the cost of recycling is low, equal or more than manufacturing the product? Since most companies value everything with profit which they have full rights to, they are not too open-minded about recycling if the cost is equal or more than manufacturing a new product. This makes perfect sense because you will not help the environment if you are also losing money. What we should work on is a means that will reduce the cost of ...

Like fossil fuel the stock of underground water is limited and it is needed to stop, its use at agriculture. Somewhere water from rivers is supplied for agriculture but to send the water pumping machines are used creating a huge fuel expense and pollution.

The project ‘CWSA’ may be a successful way to save underground water and also produce hydro power which can be used for other purposes. Supply of water for agriculture will be fully cost-less which will help to reduce cost of cultivation.

For it, a large water tank like drinking water supply tank is to be installed at the river side up on a tower. The water from this tank will reach the field through a ...

An agreement has been reached between scientists that mercury exposure today is so high in many areas of the globe that it threatens human health. Mercury compounds have carcinogenic, mutagenic and teratogenic properties. Therefore, the Minamata Convention to limit anthropogenic mercury emission was signed in 2013 and ratified in 2017. To limit the anthropogenic mercury emission will be significant for creating a cleaner atmosphere in the future.

Coal combustion in coal-fired power plant is one of the main sources of anthropogenic mercury emission around the world, and the mercury released into the atmosphere with the flue gas emission. In the coal-fired flue gas, elemental mercury, Hg(0), is difficult to be controlled due to its high volatility and low solubility. ...

Based on aggregated data, Indonesia produces 700 – 800 kg coffee beans per hectare, while in Vietnam coffee yields per hectare stands at 1500 kg and in Brazil at 2000 kg. Indonesia has 3 times the number of smallholder coffee farmers than smallholder coffee farmers in Vietnam, yet the productivity of our smallholders coffee farmers is just 1/3 the productivity of Vietnam. The root of the problem is the coffee farming practices in Indonesia are still based on traditional ways. Smallholder coffee farmers and even government and also private sector are basically practicing based on trial and error.

We believe that to actually change the way of coffee farming practices in Indonesia, we have to be as close as ...

Today, the demand for sustainable energy is crucial for tomorrow’s bright future. Tokamak-style machines claim to be futuristic superconducting batteries but, no perfected model has been achieved. The biggest limitation they’ll have when perfected is being stationary. Deep space exploration has 3-major challenges that need answers first; electrical power, shielding protection, and cheap reliable propulsion. My diamagnetic field engine (DFE) transforms into a superconductor to create power, protection, and propulsion. DFEs use 2-diamagnetic field capacitors (DFC), 1-NDFC and 1-SDFC. Each DFC has 6 magnetized pieces; 1-primary (piston) and 5-barrier (1-release plate and 4-quarter circular segments). If the piston’s internal dipole is north, then it’s a NDFC, if the south dipole’s inside then it’s a SDFC. DFEs are supported by ...

Renewable energy solutions come with their own problems, and managing the trade-offs will determine the success of a technology. Especially, with a desire to maintain and expand our modern standards of living. The diffuse, intermittent, and unpredictable nature of wind and solar energy has led to research and development in how to store the electrical energy generated. However, a partial solution to the intermittent nature of wind and solar energy is to transition our more modern refrigeration systems back to ice boxes.

Storing electrical energy, in cars or wall batteries, could be a partial solution to the intermittent and unpredictable nature of wind and solar energy. The battery storage solution comes with its own set of problems, to include ...

EXECUTIVE SUMMARY

1.1INTRODUCTION
In the world, usage of electricity is increased day by day for each and every purpose of people. If the necessity of electricity increased but the production level is low. The main purpose of this invention is cost effective, without fuel, no pollution, noiseless, and constant power supply without fluctuation.

In this product specializes in helping home owners and business owners become more energy efficient with the ultimate goals of helping them to save money on their utility bills, decrease consumption, and increasing the comfort of their home and industries.

PROJECT OBJECTIVE
The objective of this demonstration project is to develop and demonstrate a power delivery system using existing equipment where possible. The ...

Environmental contaminants like total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAH), and polychlorinated biphenyls (PCB) persist for decades in soils and sediments, and have been linked to cancer, immune and nervous system disorders, reproductive and developmental abnormalities, learning disorders, birth defects, and other health concerns. Traditional remediation methods are expensive and can further damage the environment. The estimated cost of remediating contaminated sites was estimated at $6-$8 billion annually in the U.S. and $425-$500 billion globally, mostly for remediating soils. Current cleanup methods include soil dredging, soil capping, and excavation. Dredging and/or excavating to remove contaminants is expensive, time consuming, and labor intensive, and risks harmful secondary effects such as damage to the ecosystem and the release of carbon ...
