These floating survival shelters rise above flood water, filter water and don't capsize

For those facing floods and rising sea levels, designers at Yanko Designs have developed the Duckweed Survival House, allowing people to seal up and stay upright in case dangerous winds or rain would threaten their safety.

The design is similar to a life-raft with a few modifications and improvements.

The ball at the bottom acts to keep the flotation device balanced and upright.  It also intakes water and filters it with reverse osmosis so the people on-board have fresh drinking water.

It inflates quickly due to a carbon dioxide gas chamber in the bulb that acts as a pump.  Fresh air also enters the raft through an air filter on top.

Individual shelters can be clustered together to increase stability and improve visibility.  Because they are marked with fluorescent markings, they are easily seen at night.

The design won the 2015 Red Dot award and promises to be life-changing in times of need.
