INTRODUCTION

Trees naturally convert CO2 into oxygen. But today humans are cutting trees and forests.

Solar oxygen Tree is the successful marriage of the most advanced technology and the aesthetic requirements of the urban environment by way of renewable energy.

FEATURES

Power generation using windmill

PRINCIPLE OF ELECTROLYSIS

• Water decomposes into hydrogen and oxygen.

• When electrodes connected to battery are inserted in water, we get:

• 2H2O --> 2H2 +O2

WORKING OF COIN OPERATED BATTERY CHARGER

The coin-operated mobile phone charger is already successfully installed in hundreds of locations worldwide, providing a unique service to the public and a source of revenue for site providers. The coin-operated mobile charger can be quickly and easily installed in any business premises.

The charger offers a unique revenue opportunity for a vast range of businesses - from airports to pubs, from universities to health clubs; virtually any location where there is a high footfall, creating a large number of potential users.

The mobile phone market is a billion pound industry, and the launch of new generation mobile phones with cameras and video, means the battery life of todays mobile phone is becoming noticeably shorter. One of the most annoying things that can happen to a mobile phone user is a flat battery, particularly at inconvenient times when access to a standard charger isn't possible. The coin-operated mobile phone chargers are designed to solve this problem.

The charger operates like a vending machine; all a user has to do is plug the mobile phone into one of the ten adapters and insert a coin, the phone will then be given a micro-pulse fast charge in just 10 minutes! Note: The charger is designed to provide an emergency top-up - extending talk time for a few hours. It does not bring a mobile from 'dead' to fully charged (full bars) in just 10 mins! It is, of course, possible to continue charging the mobile by inserting more money.

This compact and lightweight product is designed to cater for the growing number of mobile phone users worldwide. The charger can charge up to 10 different mobile phones simultaneously. It will extend low mobile phone talk time, provide battery charging, and also sanitise the mobile phone using ultra-violet light

CONCEPT OF ZIGBEE

A wireless network used for home, building and industrial control.

Maximum speed of 250 Kbps at 2.4GHz.

Transmission range for Zigbee is roughly 10-100 meters

In our project ZIGBEE is used for broadcasting alert messages and monitoring solar tree status

VERTICAL AXIS WINDMILL

WORKING OF WINDMILL:

Each airfoil can be rotated around its own axis with the help of a top mounted central weather vane. The central vane keeps the cam shaft pointed at the winds. In high intensity winds, the airfoils can be rotated to a zero angle of attack in order to prevent any kind of damage.

The main central fixed shaft is heavy and can withstand any possible wind load.

In order to make the structure lighter and less complex, the airfoils are attached to the carousel at the top and bottom. This gives the main spar of the airfoils extra freeness to rotate and also makes the overall structure lighter. The central weather vane and the cam moves extremely slowly and only with shifting wind direction.

All the forces experienced by the airfoil are transferred to the carousel through the airfoil’s mounting bearings. The push rod and bell cranks don’t perform much work. They just control the attitude of airfoils, close to their center of lift. The airfoils are so mounted that their point of rotation is forward of their center of lift. This will allow them to have a natural tendency to weather vane.

APPLICATIONS

It can be implemented at various places.

FUTURE SCOPE

CONCLUSION

Deforestation is increasing consistently leading to many disadvantages of which reduced oxygen and increased carbon dioxide is the major concern.

Replacing the natural trees with the solar tree not only helps increasing the oxygen levels but also is useful for many other purposes, that too with the help of renewable source.

It takes years for trees to grow, but in case of this technology, the trees can be set up in less time.
