Solar Powered Bird Scarer

The solar powered bird scarer is a device to scare birds away from different locations varying from large crop fields to airports and urban areas. This scare crow device uses natural bird distress calls to drive them away from crop fields and other populated areas. The device is powered by Photovoltaic Cells, also called solar panels. These devices are portable and water proof.

The bird movements over a wide area is detected by the device using infra red sensors. Once such a disturbance in the area is detected, the device produces distress calls to drive away the flock of birds. This system is very effective, portable and is independent of any external power supplies.

Photovoltaics: Solar PV installation, Kent

A 2.6 Kwh installation for a domestic residence.

Simon Mallett is a long term user and advocate of alternative energy having had solar water heating panels since 2003 and experimented with wind turbines over the last few years. With the introduction of Feed in Tariffs he decided that now was the time to install even more solar panels, this time as a sound financial decision to both save the planet, save money and this time make money with a clear view on a return of about 7% to 8%.

For SolarUK, of course we were keen to add to Simon's solar roof, but we had to consider that although from the outside it looked a fairly straightforward slate roof, in fact it wasn't just any old roof being a super insulated warm roof made up of jablite panels, one of the few in the UK, though Jablite warm roofs are more common in the Scandinavian countries.

Being a self builder Mr Mallett had a very clear idea of the challenges faced and SolarUK was able to work with him in developing a fixing system that would stand the test of time and preserve the roof in the best condition, something that we as solar panel installers have been doing for many years.

The 2.6kW system was decided on as being of a size that allowed for a single run of panels preserving an attractive look to the roof and avoiding a mish mash of panels every where they might just about fit.

Also, being a larger property we had to consider cable runs, the cables being run through the floor within plastic trunking, in this case prepared by Simon ready for our electrician to complete all connections.

The system is now up and running, feeding electricity into the grid and earning the Mallet family a regular Feed in Tariff income.

Manually Operated Paper Recycling Machine-Design

The aim of this project is to design and construct a manually operated paper recycling machine.

As paper is one of the most used material in the world, the waste produced during its production, usage as well as disposal are very high. Since paper is made of natural materials its decomposition is easy. But if properly recycled, the material can be converted into useful products. As we know, the main raw material for the production of paper is wood and plants. The destruction of forests for obtaining these raw materials will result in an ecological unbalance. If paper can be recycled to be used again, such mass destruction of the environment can be prevented.

The paper recycling machine consists of 6 main units such as:
1. The disc Refiner
2. The Hydropupler
3. The headbox
4. The Felt Conveyor
5. The driers
6. The Rollers.

Simple Magnetic Levitation Train

The world continues to expand with the increase in population. This is leading to the growth of cities and causing congestion in the present cities. If this trend continues, then the normal modes of transportation won’t be sufficient. This problem can be solved by making use of electromagnets and superconductors. These concepts can be made to design a train that floats on the track rather than on it.

This project “Simple Magnetic Levitation Train Btech Mech Project” aims to determine the effect of load on the friction force in the levitation train. In this project the principles of magnetism are applied. This project can be applied practically in today’s world as these levitation trains are low on maintenance and devoid of tracks that cause friction.

Working:

In this project Simple Magnetic Levitation Train Btech Mechanical Project Report two magnetic strips are used as rails and are glued to a long piece of wood in a manner that the north side of the strip is up. In the same manner two magnetic strips are placed at the bottom of the train. This should cause the train to levitate as the North Pole and train magnets face each other. The train also might slide to left or right but can be controlled by side rails.

In the setup of the project, the foundation of the wood track foundation is used. The plastic angles are mounted in the next step. Now comes the important part i.e. high force magnetic strips are mounted. These are mounted on the train block. This train is then set on the track.

Conclusion:

This experiment establishes the levitation project by making use of the principles of magnetism. If the magnetic strip is doubled then the magnetic levitation of the train goes faster. As distance reduces, the repelling force multiplies. The most important application of this project is Trans rapid magnetic lift trains.
