This project is about building a new mechanism for cooling vehicle batteries when they are being charged. This new mechanism follows the law of Tubular heat exchanger. The heat exchanger encloses the batteries which are sealed to be waterproof. As shown in the figure, the car has three openings. One for charging, the second input opening for the cold fluid or water to cool the batteries and the third opening for a hot fluid or water outlet from cooling the batteries. When the driver is charging his/her car he/she will also attach the two valves for quick cooling the charging car. Assuming the battery has +45°C while being charged, we can manage to bring down the temperature to a ...

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. ...

Bottles of water and aluminum/paper cans are inserted into the machine, shredded by blades and collected in a local area to be used later for recycling. The raw material is made up of bottles and cans in the streets and houses and trash cans. This machine consists of two parts: mechanical and electrical, the main focus of this project is on the mechanical part. Due to the dimensions of the cutting (2*2 cm in size and adjustable to different dimensions with roasting or square forms), which, in addition to easier transportation of crushed material, occupy less volume and result in increased quality of recycling.

Low noise and safety when using and also can use solar energy as a power ...

A drive unit comprising a two part-electric motor and a gear box coupled thereto is known. Gear box that is needed to reduce the output speed and thereby increase the torque. A disadvantage of the known drive unit is that it results in substantial costs, such as the gear box and its coupling to the motor exceeds two and more times the value of the motor itself. Furthermore, the presence of additional knots and details leads to the appearance of gaps, unevenness and noise at work, with an increase in details reducing the security of the product itself.

This is avoided by the proposed cyclo motor. In cyclo motor we have a unique combination of functions of the motor ...

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 ...

Automated/controlled deployment stretcher barrier wall or DSBW for short. Designed as a remote operated/Autonomous mobile deployment stretcher barrier wall the operator/user has full control capabilities allowing user to minipulate the defensive barriers movement via control center and or a wireless military touch control wrist monitoring device. The wrist monitor has a wireless password protected ID that pairs to the defensive stretcher wall barrier to gain access for control functions. User/operator has ability to view the defensive barriers 3d sensory cameras in real time through the wrist monitor or via control center. DSBWs panel flaps are manafactured as a harden steel/kevlar composite material. DSBW has crawler tracks for maximum grip/movement in all conditions. DSBW has a built in stretcher that ...

Generally a communication system is made-up of “transmitter, channel and receiver.” The architecture of narrowband receivers has had many changes since the beginning of the 19th century, but in recent years (2002~2019), design of multistandard receivers has become very important for designers because users prefer to receive all RF signals (such as Radio, TV, etc.) by one device. Commercial multistandard devices (e.g. Cellphones) are composed of many Surface-Acoustic-Wave (SAW) filters and receiver-circuits in one RFIC package for picking-up and demodulating signals, but recent studies have been focused on wideband Low Noise Amplifier (WB LNA) that these efforts will lead to have a SAW-less multistandard receiver with one WB LNA.
