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 ...

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 ...

This is a process of identifying plastic according to their polymers using the latest and state of the art technology and sorting them out in automated manner. Perhaps this is the first of its kind.

LIBS and FTIR are laboratory tested and commercially applied. We just have to integrate the LIBS and FTIR device, more likely separately , in a machine to identify the type of plastic with automated movement during identification and separation process.

This is a development or improvement in the collection and sorting of plastics compared to manual means of separating different types of plastic since the identification of type of plastic is done quickly within microseconds only or in less than a minute for hard to determine ...

At this point, awareness of plastic is not an issue. The critical point is proposing new ways to replace, manage and dispose of plastic material that is used for a different use. One of the widely used plastics is plastic bottle packaging. This packaging helps plastic bottles be easily manageable for storage and transportation. But as you surely noticed those plastic packaging end up in landfills as they are easy to manufacture.

This project offers a new type of packaging plastic bottles so that plastic packaging will be omitted. This mechanism is very simple less cost and do the task. The device is using hard plastic belt type mechanism to hold the plastic bottles together. Since the bottom part ...

Here we present a modification in the elevator (lift) which can easily harvest the waste energy when the lift will be in operation, which will be due to the Recyclable Triboelectric materials. This modification increases the energy efficiency of the building. There is waste of energy during the up and down motion of an elevator and some amount of this energy can be easily harvested by this modification in the elevator.

Here we will be introducing the concept of Triboelectric Nanogenerator. Basically, triboelectric nanogenerator is a concept of generation of electricity by having rubbing action between two triboelectric materials or either when they come in contact and separated, there is an electron transfer between these materials, which can be ...

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 ...

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 ...

In extreme hot summer, many people, particularly the elderly, can suffer heat-stroke and die. For example, in 2018, there were more than 65,000 global deaths due to extreme heat wave. Therefore, air-conditioning is no longer a luxury but a necessity.
Air conditioners literally save lives and improve quality of life both at home and at work. So why are air conditioners not available everywhere? Present day air conditioners, invented in 1902, face a number of challenges. Firstly, they consume huge amounts of energy; secondly, they cause significant environmental detriment due to the use of chemical refrigerants; and lastly, to cool a desired location, they dissipate large amounts of heat to the environment; creating undesirable heat zones.

Conventional water-based ...
