Man Invented Solar Heated Tent for Indian Army Soldiers, who are posted in Freezing Cold areas…

World’s first Solar Heated Tent was built by Sonam Wanchuk, an Indian engineer, innovator, environmentalist and education reformist. In his video on YouTube, Sonam Wanchuk introduced his new invention of Solar Heated Tent For Indian army at galwan valley. Let’s know some important details and innovative ideas which he has used for building his amazing Solar Heated Tent.

As we know it’s hard to survive on mountains but hats off to those soldiers who spend most of their time on borders, no matter how harsh climatic conditions they have to face, they are ready to serve their country at any cost, even the cost of their lives.

In his interview, Sonam Wanchuk described how hard conditions army soldiers face during their duties on cold climatic mountain regions, they have to live there in typical tents which hardly saves them from extreme cold or they live in iron containers which are costly and non portable.

This inspired Mr. Sonam Wanchuk to invent a solar heated portable tent which is his 15 years old invention, he first made this Solar Heated shelter for nomadics of Kashmir. He saw that Indian army soldiers who are posted in Galwan valley in winters are facing so much trouble as the temperature of this place remains low. Thus he decided to do something to address this problem of soldiers, he started working on a passive solar heated tent project, so that soldiers could stay comfortably in harsh climatic conditions and they don’t need to use fuel for heating which harms the environment.

Let’s Look Inside The Passive Solar Heated Tent

This Solar Heated Tent is divided into two parts, first is the greenhouse part which absorbs solar heat from the sun and second is the sleeping chamber, where people could sleep at night. The part of the sleeping chamber is highly insulated and waterproof. In the daytime Greenhouse part remains warm as it obtains solar heat. The wall dividing two chambers works as a heat bank. This wall stores heat and it enables the sleeping chamber to remain warmer at night when temperature gets lower.

The walls of sleeping chamber are highly insulated that means they trap heat and resists the cold at night. Sleeping chamber section is heated by a heat bank wall, which stores maximum solar heat from the greenhouse part at day time. That’s how this amazing solar heated tent works. The cost price of this solar heated tent is around Rs. 5 lakhs or 6,891.39 us dollars.

Top 5 Straws to Stop Ocean Pollution

It is estimated that billions of single use plastic straws are produced, used and thrown away everyday. We use a straw for minutes but it remains in the environment for 200 years as a land and Ocean pollutant. Most of the single used plastic straws are non biodegradable and toxic. These straws’ last destination is either water bodies (due to beach littering) or landfills. On land areas these thin plastic straws are prone to get consumed by stray animals along with leftover food. If we talk about water bodies, marine animals are getting affected by disposed plastic straws. These animals consume disposed straws, which becomes the reason for their death.

Single used plastic straws are widely used and it will be difficult for people to quit it until they are not provided with any solution. There are lots of alternatives of typical plastic straws but most people are not aware of them because these options are not as popular as typical fancy plastic straws. Let’s know the other kind of straws which you could switch to in order to save your Planet!

#1 Stainless Steel Straws

Stainless Steel Straws is a good option if you are fond of the Zero Waste lifestyle. These straws are made out of stainless steel, which means they don’t get rusted. Steel straw is long lasting, washable and reusable for many years. You can carry it anywhere to avoid using plastic straws.

#2 Bamboo Straws

As steel straws bamboo straws could be reused. They also last longer but not as steel straws. These straws are biodegradable and made out of bamboo. It means they don’t pollute landmasses, these straws easily dissolve in soil.

#3 Coconut leaves Straws

These straws are very eco-friendly and making progress doesn’t harm coconut trees. They are simply made out of dried coconut leaves, which fall apart from trees. If we talk about its durability, these straws can’t be reused. Coconut straws are decomposed very fast and provide organic matter to soil.

#4 Edible Straws

Have you ever heard of edible straws? The straws which you could eat after drinking through it. These straws are made out of grains. These straws are not long-lasting and reusable but the good thing is, these straws don’t create any waste and if you throw them in waterways they become food for marine animals. Isn’t it amazing!

#5 Paper Straws

Paper straw is good because it’s biodegradable but if we talk about other qualities, it’s not as sustainable as straws which are mentioned above. Paper straws are not long lasting and can’t be reused. Trees are cut for making paper, however paper straws are easily dissolved in soil and don’t create pollution. Which makes these straws far better than plastic straws.


I think small changes could help all of us to achieve big goal of sustainable future. I personally like to use Stainless Steel Straws. It could be carried, washed and re-used easily for longer time.
