Float helps you unwind in water without an isolation tank

In an increasingly busy and relentless world where information is flowing all around us, it’s more important than ever to switch off once in a while. There are many ways to relax, but floating in water is one of the best ways of completely and utterly drifting away. Which is where Float – designed to make floating in water a more pleasurable experience – could prove useful.

Float is a water therapy product originating from Iceland. It’s designed to aid total relaxation of body and mind by taking the effort out of floating on water. You can probably get a similar experience by floating in the sea, as salt water is denser than freshwater. But floating mindlessly in the sea carries the risk of being taken away from shore by an outgoing tide. As Float is designed to be used in a swimming pool, it’s likely to be a safer alternative.

Inexpensive new solar still ups water purification efficiency

In areas where clean water isn’t easily accessible, solar stills can help purify available water that might be dirty or salty. These devices absorb heat from sunlight and use it to evaporate water, leaving behind contaminants and reforming as a liquid in a separate container, and although they work, they can be relatively expensive and inefficient. Researchers have now developed a new type of solar still using carbon-coated paper that they say is cheaper and more than twice as efficient as existing devices.

Solar stills can be live-saving devices for people in developing countries or disaster-affected areas, but there’s room for improvement according to the team made up of members from the University at Buffalo (UB), China’s Fudan University and the University of Wisconsin-Madison.

“People lacking adequate drinking water have employed solar stills for years, however, these devices are inefficient,” says Haomin Song, a co-author of the study. “For example, many devices lose valuable heat energy due to heating the bulk liquid during the evaporation process. Meanwhile, systems that require optical concentrators, such as mirrors and lenses, to concentrate the sunlight are costly.” Read more
