Behold The Future…Behold The Tent Of The Future! Collects Solar Energy, Rainwater, And Folds Up For Easy Travel
When people are asked what type of people are part of the green community, most have a stereotypical view of hippies that live off the grid. In reality, it is comprised of many people including organic farmers, biotechnology scientist, and even public figures. One group of people in the green community are inventors and designers, people innovating the way we live. Utilizing basics of green technology, many have invented spectacular innovations. Gabriele Diamanti invented a distiller that runs on solar power. Lifestraw invented a self-named device that makes the filthiest water drinkable. And Jesper Frausig invented electric bicycles powered by solar panels.
Though the aforementioned are beneficial for mankind, providing water and transportation efficiently, what about dwellings? That concern has been dealt with as “tents of the future” are able to provide shelter efficiently. Not only that, they collect solar energy to charge batteries, collect rainwater, and fold up neatly for easy transport.
According to Minds, the tent is designed with a weather-proof fabric attached to bendable, compressed plastic which can open to create vent holes and exits and seals. It is strong, sturdy structure and has the capabilities to fold up for easy storage and transportation, collect rainwater, and charge electrical reserves (batteries for example) with its solar fabric.
Though most would think such tents were designed and invented to provide an alternative to conventional housing, that is actually not the case, though it is possible. The tent’s creator, Abeer Seikaly, had in mind the millions of refugees driven from their homes due to the aftermath of global wars. The tents provide a means for them to settle in a new land. This is also why the tent is part of a project known as “Weaving a Home,” because the tents are just a major step for the refugees to “weave their lives” back together in which the tents will turn from a shelter to an actual home.
More information on the tent can be found at Abeer Seikaly’s official website (already linked above). It details the science put into the tent, but also shows other projects Seikaly is currently a part of.

These freaking awesome tents get solar power, can harvest water and fold up.
“This weather proof fabric is attached to strong bendable, compressed plastic which can open to create vent holes and exits and seal to keep warm. It’s a very strong, sturdy structure that can fold up, collect rainwater and charge a battery with solar farbric.
It was developed by Abeer Seikaly, with the Weaving a Home project and was intended for refugees. It has popular appeal as well.”
