Aeroponics

Description
Friends, this super cool idea of Aeroponics is just awesome. This can be created easily within 5-10 days depending on  the level you want.In this project you can cultivate pants without soil and much faster.  

Material Required

• High Power Water Pump
• Flexible thin water pipes
• Plastic trays (minimum two)
• Mini spray nodes
• A tub or bucket
• Plastic foam or cloth
• Red led lights
• A stand 
• Plants of short height
• Power supply
• fertilizers (which can be dissolved in water)

Procedure

Make stand of required dimensions such that it can hold trays like in above picture .Place the trays firmly place trays at distance 4-5 inch greater than that of your plants .Make the whole structure and fit pipes with spray nodes at interval of 3-5 inch.Place plastic foam or stretched clothes with small holes to insert plants , make sure that roots of plants are suspended in air , the pipe should be single pieced coming from a water bucket or chamber the water pump should be connected in between bucket and stand the pipe should end in the same bucket. Dissolve the fertilizers in water bucket. The pressure of water should be moderate. Your plants will grow without soil and excess of water.Also fix LED lights on top of plants under trays.

Precautions

• Make sure that wires are away from water.
• Wires should be properly insulated.
• The whole system shouldn't leak from anywhere.  

Advantages

This project has following advantages

• Crops can be grown easily at regions having harsh climate and infertile soil.
• Growth rate of plants increases as their is no barrier and plants grow without competition.
• This can be easily applied in low space and urban life.
• Plants cant get affected by any pests.
• Plants produced are of good quality.
• Initial setup cost can be high but it runs with minimum investments.

Biodiesel

Requirements: -

• Vegetable Oil
• Antifreeze (Methanol)
• Lye (Sodium Hydroxide)
• Blender
• Scales
• Plastic Containers
• Thermometer
• Duct Tape
• Funnels
• Plastic Bottle with lid

Steps Involved : -

·         Step 1: -

Measure out 200mL of antifreeze and put it in a plastic container.

·         Step 2: -

Add in Lye so that antifreeze is absorbed.

·         Step 3: -

Cover container and mix well by shaking it. It is mixed when it starts to feel warm and is foamy. The mixture now has become Sodium methoxide. 

·         Step 4: -

Blend one litre of vegetable oil with the sodium methoxide in a blender for 20 minutes

·         Step 5: -

Pour the mixture into a bottle and wait 8 hours until the byproduct, glycerin, separates from the biodiesel. The glycerin will be the solid on the bottom.

·         Step 6: -

Separate out the biodiesel by pouring into a glass bottle.

·         Step 7: -

Prepare a wash bottle by poking a small hole in the corner of the bottle and covering it with duct tape.

·         Step 8: -

Wash the biodiesel by pouring it into the wash bottle and adding in a half litre of water. Roll the bottle around to mix it and then remove the duct tape and drain the water.

·         Step 9: -

Repeat the washing process until the biodiesel is clear. This may need to be done numerous times over the course of a week to complete the process. Store the Biodiesel in a glass container until ready to use.
