In countries like India where the average temperatures remain 30 to 40 °Celsius (90 to 104 °Fahrenheit) throughout the year, ACs and Refrigerators are a must. Being a developing country, not everyone can afford those lengthy electricity bills and the expense of electrical appliances.
We all know that air conditioners contribute to global warming due to the heat that is dissipated from these devices. But, the cooling is definitely needed for people at their homes. Thus, a team of Indian designers has built a boundary-pushing structure that cools the air without using a single watt of electricity – and looks like a modern art installation at the same time.
Also, on the other hand, there is this one man Mansukh Prajapati, a traditional clay craftsman who has built a mini-fridge known as 'Mitti-cool' that can keep all the vegetables fresh for at least 3-4 hrs.
Let's get into details of these coolest inventions.
Pairing up with Deki Electronics (based in India's national capital, Delhi) the team of engineers from Ant Studio used a circular metal frame to bind hundreds of terracotta clay tubes, creating the Beehive.
When soaked, the terracotta clay tubes that are used in this invention, absorb the water and evaporate cool breezes as warm air pushes through them.
It is a low maintenance, economical (due to the low cost and high availability of clay), and an eco-friendly invention that has been made to suit the needs of people of the country having the hottest temperatures.
"As an architect, I wanted to find a solution that is ecological and artistic, and at the same time evolves traditional craft methods," Monish Siripurapu, founder of Ant Studio, told Arch Daily.
Isn't it cool? It looks like a beehive and functions to make lives easy.
It is that it doesn't even need or consume a single watt of energy or electricity for itself. It acts like a natural AC that will not be the reason for global warming like other conventional ACs.
Now, time to know about another great invention.
Here's one more cool invention that doesn't consume electricity, a mini-fridge that can keep your vegetables as well as milk fresh for days.
In February 2001, Sandesh Gujarat Daily carried a photo feature on the earthquake where at one place it showed a broken water filter of Mansukhbhai with the caption 'The fridge of the poor got broken'.
This caption motivated him to work hard and create a fridge that could be used by rural masses.
It does not require electricity or any artificial energy and therefore has no recurring costs. The refrigerator preserves the original taste of fruits and vegetables.
The Mitticool refrigerator has been featured at a conference organized by the Centre for India and Global Business, Judge Business School, University of Cambridge, the UK in May 2009.

That's all folks!
