How to reduce your room temperature without any AC or other cooling machines ?

You can reduce the temperature of your room if you have the following : 

1.An Aquarium full of fish and live plants 

2.Silica Gel 

3.Dwarf Bamboo Tree 

When you put the above three items in your room just under the window, room temperature will be reduced drastically.

When you put the above three items in your room just under the window, room temperature will be reduced drastically .

Logic :

Heat will always flow from higher to lower temperate region. In summer, outside temperature is more than room temperature. So, heat enter our room and increase the temperature so that an equilibrium can be achieved. But in turn this incoming heat raise the temperature of the room.

During summer air is full of moisture. When the relative humidity is very high we face a sultry condition. 

So to reduce the incoming heat we will need something more cooler than our room. And to reduce the moisture we need something that  can absorb it.

Aquariums are much cooler than our room. The fish in the aquarium cools it further as they are cold blooded. Thus making the adjacent places cooler. You can feel this phenomena by visiting any gift shop.

You will feel that places where the fish tanks are kept are more cooler than the places far away from them, in the same gift store.

Generally our rooms are not as big as the gift store. So a simple rectangular glass tank with some live plants are enough to reduce the room temperature.

If your room is big you need a big aquarium and if small ,general aquariums will serve the purpose.

Silica Gel will absorb the moisture in your room.Place 250 grams of silica gel just beside the aquarium.

More oxygenated air in your room will increase the CI (Comfortability Index) of your room. More Carbon di Oxide will do the opposite. Any plant will consume Carbon di Oxide to make food and release Oxygen as the byproduct. So  a plant in your room will always increase oxygen and reduce Carbon di Oxide and thus increasing the CI.(But the problem is at nighttime plant will absorb Oxygen and release Carbon di Oxide )

Dwarf Bamboo trees can provide release large amount of oxygen in the room.So keep 2 dwarf bamboo tree just beside the aquarium.

So,

Moisture : Absorbed by Silica Gel

Heat : Reduced by Aquarium

CI : Increased by the Dwarf Bamboo Tree.

Even after you place all these, your room will not be as cool as an A.C room . But you will not face the ill effects of the scorching heat and humid conditions that are common in Summer .As moisture is absorbed and the thermo-stat like cooling is done by aquariums ,you can keep A.C out of your house.

Harmful Effects of A.C

• Freon is a fluorocarbon gas which is nonflammable but releases CFC(reacts with Carbon die Oxide of air) in air which is extremely degradable for our environment.
• Increase the electricity bill drastically.
• Creates Noise Pollution.
• Constant exposure to this artificial cooling can disturb heat balance of our body and often causes cold and coughs.

How do ancient human cool their house ?

Sprout waters on the roof and when the water evaporates it cools the rooms below.It is followed even today in the villages of Rajasthan,Jaipur.

Kings of Jaipur uses jewels and mirrors in the walls and ceiling of their palace to regulate temperature. 'Mirrored and bejeweled ceilings and walls retain warmth or render a room cool as the season demands.'(from Travel Photo Essay: Dreaming of Rajasthan, India by Sujatha Bagal)

An earlier form of air cooling, the wind-catcher (Bâd gir), was invented in Persia (Iran) thousands of years ago in the form of wind shafts on the roof, which caught the wind and passed it through water and blew the cooled air into the building.

The ancient Egyptians were known to circulate aqueduct water through the walls of certain houses to cool them. As this sort of water usage was expensive, generally only the wealthy could afford such a luxury.

Medieval Persia had buildings that used cisterns and wind towers to cool buildings during the hot season: cisterns (large open pools in a central courtyards, not underground tanks) collected rain water; wind towers had windows that could catch wind and internal vanes to direct the airflow down into the building, usually over the cistern and out through a downwind cooling tower. Cistern water evaporated, cooling the air in the building.

Research Ideas on Water Reuse

(Image Source)

The "Impact of Urbanization on Water Reuse Potential" and "Water Reuse Potential of Hydro-Power plant" can be two of the most important topic of research  related to water reuse.

In the first topic the urbanization impact on Water Reuse Potential(WRP) is estimated.As world wide rapid urbanization is going on, the stress on "available water" of any region is immense.Due to the uneven distribution of water resources the problem is more acute where concentration of population is high but availability of water is low.According to Falkenmark's Water Stress Indicator,a region is said to be water scarce if per capita water availability is less than 5000cubicm.

Again availability of water will imply not only the quantity but also the quality of water available.The water must be qualitatively suitable for consumption.Otherwise, it will not be added to water resources potential of a region.

Due to urbanization there is an immense stress on this "available water".That is why mitigation measures like recycling water is given a lot of importance so that this increased population can be sustained and their demand for water can be somewhat satisfied.

But amount of water available for consumption is constant.Thus the supplied water must be recycled or reused.Hence,the interrelationship between rate of urbanization and WRP will be an interesting aspect to determine.The potential of urban population in degrading the quality of water is also another potential area of research which can enlighten us to determine the amount of water we have and can reclaim for reuse,

The second topic,the potential of water reuse in a hydro power plant will help to install a zero discharge hydro power plant which will be beneficial for both water as well as energy conservation of a region.In the study one objective will be to find the amount of water available for reuse.

Another aspect will be to determine the types of use that can be carried out with the reused water.Actual potential of water reuse can be given by a weighted index of all the purposes of water reuse.Each of the purposes can be weighted with respect to each other following some Multi-Criteria Decision Making approaches.

Once the amount of the water that can be reused for specific purposes are known,it can be multiplied by the weightage of the same purpose and total of the product of weights of all the purposes and available water for that purposes can be used to determine the WRP Index of the hydropower plant.

The index can represent the exact WRP of the plant in terms of the potential of the reused water to mitigate the demand of the plant intself.

New Research Idea : Selection of Conceptual Hydrologic Models for Estimating Runoff from Arid Watersheds

Abstract : 

The selection of ideal conceptual hydrologic model for prediction of surface runoff from any type of watershed is useful for the estimation of future hydrologic conditions of the basin.The predicted runoff is also important for design of hydraulic structure,preparation of watershed management plans ,disaster management etc. related activities.The future runoff will give an idea of future uncertainties that may trouble the watershed and its inhabitants.The hydrologic models which follows the basic physical laws of water balance to estimate the desired output cannot exactly estimate the runoff.There will be some differences with the actual situation and the predicted one.The deviations between the two is allowable but to a certain extent.There are many factors for this deviation.Some models are suitable for some specific types of watersheds.The availability of required dataset is also another important issue.The equalizing constants that are used to linearize interrelationships are also a factor for the error produced by the hydrologic model.That is why  selection of a suitable hydrologic model which can estimate at a desired accuracy under the restrictions imposed by the study watershed  and dataset availability is important for successful execution of projects involving runoff predictions.The present study tries to select a suitable hydrologic model based on the related factors and decision making algorithms for predicting surface runoff from an arid watershed.The decision making algorithms are popular for their impartial and scientific decision making based on historical,social and expert inputs.The advancements of such algorithms can be utilized to select an ideal hydrologic model which can minimize the error between the predicted and actual output.
