The issue with lithium ion batteries is that in each one there is enough electrical energy to create a spark, and they are filled with a flammable electrolyte. The only thing preventing the spark is a thin plastic separator, sometimes less than 10 microns thick. If there is a defect or damage to the cell that penetrates the membrane, then a spark occurs and the battery can light on fire.

What if you could make a battery in which it was impossible to create a spark?

We present a new lithium battery architecture which does just that. In this architecture, the metal foil current collectors have been replaced with polymer films that are coated with just enough metal to ...

This solution is based on a strategy and an invention. Earth has its own system to balance its temperature. Human activity distrupts this balance. Earth reduces its temperature by ice poles as a natural cooling system. We should just help the poles to repair melted ice then reduce global warming. Setting cold blowers (invented system) by plane can produce or strengthen cold fronts at the poles to repair the cold ...

1) As already described in 2017 and 2018 entry a body sliding on an inclined plane can be supported by a thread or support perfectly parallel to the horizontal.The weight of a body that is unsupported even at the position of rest by this mechanism is maximum for a plane of inclination 45°as explained mathematically in preprint manuscript doi:10.5281/zenodo.439108 causing compression of spacetime below and expansion of space time above the supporting surface.Here technical modification is made to support the body by a perfectly horizontal thread or support on a plane of increased inclination by way of pressure by an elastic recoil force.

2) The modification has weight of body sliding on inclined plane IP1 and IP2 of lightweight ...

Absolute, unlimited power generation.

Under the laws of physics, to produce electricity, a magnetic field must be inserted into the wire box.

Movement of the paddle in the vacuum does not stop because it does not have air resistance.

If we move the pendulum through the vacuum to the magnet and wrap the wrap around the pendulum, the pendulum does not stop, so we can replace the electric current that does not expire.

For some reason, the pendulum is slowly moving slowly, using a portion of the electric current that it generates. The remaining electric power remains purely.
Of course, millions of layers of them will have more electricity available. Most of all, it does not need water, steam, ...

A Smart Hydroponic food module that monitors, grows and takes care of your plants. Our Vision is to foster behavior change among urban households towards farm produce and drive hyper-local urban production. We make farming so much simple and easy that now anybody can grow their own food. Gone are the days when you need hard labor and farming experience to get your harvest.

The journey began with a quest to bring in self-sustenance and pesticide-free healthy food to our home, foster behavior change among urban households towards farm produce and drive hyper-local urban production.

Further our current agricultural system is very inefficient, food produced in one corner of the country being sent to other corners, poor supply chain, ...

We have developed an integrated air quality monitoring UAS which also has collision avoidance technique to avoid collision with real time obstacles while monitoring. We have used an ultrasonic sensor for collision avoidance and mq135 for air quality sensing. We have developed a program for displaying the pollution gas availablity in percentage instead of ppm.

An anti collision system is essential for safe flight of the drone. It gives a simple solution for obstacle detection and collision avoidance in UAVs. The obstacle is detected using the ultrasonic sensor (HC-SR04).

Ultrasonic sensors work by emitting sound waves at a frequency too high for humans to hear. They then wait for the sound to be reflected back, calculating distance based on ...

The global economy thrives on energy. Affordable energy directly contributes to increase productivity, reducing poverty and improving betterment of life. The global population is increasing day by day, which, in a way is leading to the utilization of natural resources and fossil fuels. Concentrating on the limited stock of fossil fuel, efforts have been in full swing to search for sustainable alternative to petroleum without adversely affecting the supply of food with keeping the environment clean (GO GREEN).

Biodiesel from algae is the most promising renewable biofuel derived from biomass with the potential to completely displace petroleum-derived fuel without adversely affecting the supply of food and other crop products, while keeping the environment pollution free. An alga grows naturally ...

Securing the examination paper is very difficult for many counties which do not use electronic examination. This is because there are too many places that the exam will have the risk of being stolen. The low economy and lack of integrity of peoples involving the process of the examination are fooled for getting benefits by selling exam papers for students. The first risk is when the exams are being printed because you may trust the printing company but not the person printing it and arranging the printed exams. The second risk is storage and shipment because you may trust the process but you can never know who might steal the papers or copy them.

This project is about introducing ...

This project is about building a new mechanism that can sort live aquatic animals in dams from intake canal without imposing any health risk on the animals and with lower operational cost than existing fish screen configuration to prevent them from damaging the power plant and themselves. This is done by using a sorting mechanism. Most aquatic species that exist in stream of dam are on the upper level of the water. So, this mechanism uses this advantage. As seen in the diagram, the green part which is the sorting mechanism is installed in the intake line. This structure can collect the upper part of the intake water and directed or discharge it to the river which is after ...

What happens when an astronaut gets sick? Current missions require that astronauts take medications with them from Earth. But many medications degrade over time, especially protein drugs, and the necessary stockpile takes up precious mass and volume on a spacecraft. With the push towards long-term human missions to the Moon and Mars, this model is not sustainable. Even on Earth, there are many people without access to critical medicines because regional production and distribution systems are lacking, especially in remote areas, resource-poor areas and in austere environments. Our solution is an “Astropharmacy” – an innovation that allows protein drugs to be produced “on demand,” even in the remote environment of space, using genes as templates for cellular or cell-free ...
