Story of Elbow's Eco Brick 

Scotland's revolutionary Waste recycling process 

The journey of Elbow Engineers began with a profound realization. In my homeland, India, I was deeply involved in water purification and air-to-water machines. My primary research focused on developing an atmospheric water generator, a device that produces drinking water from atmospheric water vapor. This innovation stemmed from the pressing issue of groundwater contamination in India. However, I soon recognized that air quality was equally affected, though less visibly. It became clear that both air and water pollution often originate from waste landfills.

Driven by a desire to comprehend this complex issue, I began analyzing various waste materials, seeking to understand their properties and interconnections. Fate brought us to the (DFID) team during a university demo day, where we showcased our air-to-water technology. Impressed by our work, they extended an invitation to bring our business to the UK. However, the onset of the COVID-19 pandemic disrupted our immediate plans.

Undeterred, I made the decision to pursue further education in the UK, allowing me to gain a global perspective on the problem at hand. It was during this time that I discovered the alarming fact that Scotland, my new home, exports a staggering 100 tons of plastic waste to other countries every month.

This realization underscored that the issue at hand was not confined to a specific region; it was a global crisis. With this newfound clarity, we embarked on the journey of Elbow Engineers in the UK. Our mission is to address the interlinked challenges of air and water pollution, originating from waste landfills, with innovative solutions that have far-reaching impacts.

TALON (Rescue mechanism to help children fallen into bore well holes)

TALON (Rescue mechanism to help children fallen into bore well holes)

Prepared by: L. Kumar, Jyotsna R, D Balaji, C.A Anbhazhgan, Praveen, Krithika, Karthik, and Vinoth Faculty Dr. K. R Senthilkumar Anna University students Presented @ VIT Vellore Date: 3.3.07 TALON Project objectives Through talon, we aim to rescue babies who have fallen into these circumstances using a very simple method that is very economic and uses minimum resources. The entire operation can be completed within 3 hours and the cost of a real-time model is approximately Rs.15, 000 and requires three people at the most, as opposed to the conventional method wherein at least 35 people are necessary to dig and bring out the baby. The project will meet the following objectives: • Rescue the baby without causing it any discomfort • Minimum utilization of resources and manpower • Minimum time consumption Project scope • In addition to scooping out of the child parallel monitoring of the child has also been implemented to ensure safety. • Time delay for scooping out in terms of mining and digging process is avoided • A special type of sensor called tactile array sensor has been used which will measure the amount of pressure needed to hold and lift with maximum safety. And another sensor is also used is called a Pyroelectric passive infrared sensor. which is to detect whether there is life in the baby, this sensor is used to check the difference in temperature of various living organisms present in the hole • The entire operation is completed within 3 hours ( at the max) Out of scope: • This system can’t be used if the hole doesn’t come under this 3 form( GI pipe, PVC pipe,or big narrow wells) • The system can’t be used if the baby’s outer diameter equals the bore diameter… • We need to work for a longer range in the case of wire-less technology. Right now we are using the single wire method... Deliverables produced Deliverable 1: claw arrangement: (a mechanism) The limb position is controlled by two DC motors. One DC motor is used to control the arm position and another DC motor to control the contraction and relaxation of the arm movement. The stepper motor is controlled by a microcontroller (8051) Deliverable 2: Basic electrical circuit The above-mentioned mechanisms have been controlled with the help of a basic circuit diagram. In this, we have stepped down and converted the available AC voltage to DC. The entire operation, sensors, cam, and light are continuously monitored and controlled by 89c51. Deliverable 3: software The entire operation is performed by interfacing the microcontroller with the PC. This interface is done using the assembly-level language. Project assumptions To identify and estimate the required tasks and timing for the project, certain assumptions and premises need to be made. Based on the current knowledge today, the project assumptions are listed below. If an assumption is invalidated at a later date, the activities and estimates in the project plan should be adjusted accordingly. • The ground is strong enough to hold the earthmover • The child does not squirm or struggle before the belt is put • The hole is straight and narrow • Age of the child should be above 2-3 years Project approach DC motors DC hobby motors can be applied for movement and locomotion which need high revolutions per minute (rpm) and low torque. In the Talon, they are used to control the mechanisms of twisting and expansion or contraction of the claw (Talon). They are used to adjust the position of the claw so that it clamps the baby without causing any pain. Pyroelectric passive infrared sensor To detect whether there is life in the baby, this sensor is used to check the difference in temperature of various living organisms present in the hole Tactile array sensor: A tactile array sensor is used to hold and lift any object. During this process, it can easily sense how much amount of pressure should be applied to lift an object without dropping it and damaging it. CCD CAMERA: CCD (Charge Coupled Device) at the heart of this type of camera is the CCD imager, a specialized type of integrated circuit (IC) which is located Just behind the camera's lens. The lens focuses a small image of the scene in front of it directly onto the CCD imager chip, which is behind an optical glass window in its package. The detailed operation of a CCD imager chip is complex, but here is a simplified explanation of how they work. Over the active image-sensing area of the chip, there is an array of tiny sensor cells, each typically measuring 10 x 5um (micrometers) or less. The array of a typical CCD sensor has 297,984 of these cells, arranged in 582 horizontal rows and 512 vertical columns.
