In the aftermath of Typhoon Haiyan in the Philippines, aid workers are stymied by overwhelming obstacles: lack of fuel for relief vehicles, near-total absence of food, water and shelter, and social chaos on an apocalyptic scale.
The tropical cyclone packed sustained winds of up 190 mph (305 km/h) in the hours before it made landfall, according to some estimates. It will likely go down as one of the five strongest storms in the last 50 years. The death toll for the storm is expected to exceed 2,000 people, according to NBC News.
While technology can't prevent storms like Haiyan, there are some clever devices that can alleviate the suffering of survivors and provide lifesaving access to clean drinking water and hot food.
