Hydro-Thermal Weed Cleaner TEAM 1 PETER GARCIA PRAJEEP NAIR SAAD KHAN

Weeds  Weeds are a common household problem residential owners encounter. Types of damages: -Structures -Insect pests -Disease -Land degradation Pesticides  Use of pesticides is a common method to eliminate weeds. Types of hazards: -Pets -Children -Underground water pipes

Motivation  Emphasis on Green energy solutions.  Create a system concentrated on global community safety.  Halt an increase in insect pests, disease, and land degradation.

Objectives  Create a eco-friendly, cost efficient, effective system that will eliminate weeds and the use of pesticides.  Develop a system that can be used by elderly people.  Manufacture a system that can be used in a variety of environments.

Design The Hydro-Thermal Weed Cleaner is a simple system made up of three main components:  Water hose  Handle and trigger  Heating element

Concept Design

Prototype Prototype – 1.0 =>

Design Safety  A splash shield will prevent boiling water from being scolded.  A surge protector inside the heating element will prevent electrical disruptions.  The trigger will have a child lock mechanism.

Global Learning and Design  Different voltages are taken into consideration in every country.  Different environments are contemplated for the effectiveness of the system.  User manual in multi-languages is considered, English, Japanese and Hindi.  SI and English units is regarded.

Testing and Analysis  We tested the initial concept on common house weeds and recorded the results.  Initial experiments produced encouraging results.  Contrary to our intuition, the value of the heating element was higher.  As a consequence, we plan to develop ventilation in the handle for convection to occur.  Leakages is another issue we need to tackle to avoid loss of water.

Discussion and Conclusion  From the initial testing of the prototype, we conclude that the concept is practical.  More iterations in the original design needs to be done to improve the effectiveness and efficiency of the final product.  The target temperature to be achieved is 99°C.  Our aim is to convert this practical concept into a product.
