Industrial Design student Kama Jania from the Academy of Fine Arts in Cracow, Poland has created a working prototype of a lightning-proof tent. The Bolt tent is part of a series of three different tents that are each designed to protect users from direct lightning strikes and step voltage (when lightning current or discharge flows between the ground and the feet of a person).

Janiawas inspired to create the tent after reading statistics about howmany people are actually struck by lightning each year, fueled by hervery own fear of thunderstorms.

"When I was a child I wasterrified by loud thunder and lightning, even when I was at home,"Kama Jania tells Gizmag. "Now I am also scared of thunderstorms,but only in open spaces, particularly in the mountains. I loveoutdoor activities such hiking and climbing and sometimes I findmyself in a difficult situation, especially when a storm comes in.Thus I created the Bolt series of tents."

To create the very first lightning-proof prototype, Jania used aluminum poles and an aluminum connector, which can withstand 200 kiloamperes. A waterproof fabric was used for the flooring of the tent, along with Mylar insulation and copper wiring which is connected to the ground stakes.

Under the supervision of Professor Michał Kracik PhD, and alongside physicists Konrad Sobolewski and Aleksander Bogucki, Jania took on the long process of working out the exact calculations and collaborations needed to test the Bolt tent against high voltage contact, without it going up in flames or causing severe damage to the materials.

The prototype tent underwent multiple high voltage experiments, using discharges from an impulse voltage generator. Jania placed an electrode inside the tent, to represent the occupant's head and a high current generator was used to test the durability of the tent.

Jania notes that "some scorching appeared at the pole joints due to the very high temperatures reached at those points. The stakes, which laid freely on the laboratory floor during the tests, melted to some extent. Again, it was a result of the high temperatures generated at those points during the discharges."

Apart from the above, the experiments were a great success and demonstrated the tent's ability to protects its occupant from direct lightning strikes.

"I also tested a tent in the mountains during downpour and strong wind," adds Jania. "I spent more than six hours inside the tent without any break and it's comfortable. It's also really easy to use; the lock mechanism located in poles automatically set up the tent."

Thethree Bolt tents are made from lightweight and waterproof materials,aluminum rods and pegs. They are a good ideafor people who enjoy hiking or exploring the outdoors and all threeversions are compact, easy enough to carry without too muchadditional weight and can be set up in a matter of minutes.

TheBolt Half is a lightweight (1.2 kg/2.65 lb) pop-up shelter that issuitable for day trips only, as there is not enough room to lie downor sleep. It offers full lightning protection as well as shelter fromheavy rain, wind and thunderstorms. Due to its compact size it caneasily be assembled in a myriad of locations, including riverbeds, amountain ledge or ridge.

Bolt-One is a compact one-person tent, which also offerslightning protection and shelter from the elements. This tent can beused for overnight trips and is comfortable enough to sleep in.

Thethird version, the Bolt Air, is described as an ultra-lightweight pneumatic shelter, suitable as a camping accessory or once again for day tripsand hiking. Similar to the Bolt Half, it can offer protection for one to two people seated and features a groundsheet that protectsagainst step voltage. "Thanks to its size,it can be quickly and easily put up in places unsuitable for standardtents," says Jania. "It is designed for day-long tripswhere additional weight would be burdensome."

There are no current plans to take the Bolt tents into production, Jania says that she's looking for commercial partners to develop the project. She's planning on completing her master's degree next year and isalready plotting away at an idea of how to create a device that cancollect water from different atmospheric heights.

Huh. I have to wonder though if getting hit by lightning while in a tent was really something that I was worrying about? I mean, if I were planning a camping trip, I would think that I would plan it for a weekend that does not have a chance of rain, let alone a lightning storm, aha. That said, maybe there are people that like storm camping. Who am I to judge :P. Nate

Looks like a nice tent, but any tent with metal poles will provide the same protection. Right after college we did lightning protection testing. Any piece of metal stuck in the ground at two places provides a cone of protection. Still scared? Make sure the metal pole ends are poking into the dirt and then add a little pointy metal antenna at the peak of the tent. That will bleed off some of the potential in the area around the tent and mother nature will see a more tempting path to ground nearby for her next lightening bolt.

Nate, there's many places inc. many within the USA, where the weather during the late spring through early fall camping season is far too unpredictable to avoid the possibility of a thunderstorm a week ahead.

Bruce, the average tent is incinerated after being hit by lightning. But, appropriate design and materials can prevent it. I assume that this tent has such design.

So it might protect you from lightning. What can it do to keep your eardrums from being completely blown out by such a close lightning strike?

Timelord, I see that it is better to be dead than deaf ;) ..I hope that the tent includes earplugs without extra charge.

call me paranoid. lol. so is that why indians use tipi's, lightning protection on the plains.
