Selecting the right house plant could improve indoor air

Selecting the right house plant could improve indoor air | Sustainable Innovation | Scoop.it

Indoor air pollution is an important environmental threat to human health, leading to symptoms of "sick building syndrome."

VOCs are compounds like acetone, benzene and formaldehyde that are emitted as gases and can cause short- and long-term health effects when inhaled
But researchers report that surrounding oneself with certain house plants could combat the potentiall

To test this, Niri, who is at the State University of New York at Oswego (SUNY Oswego), and his team built a sealed chamber containing specific concentrations of several VOCs. They then monitored the VOC concentrations over several hours with and without a different type of plant in the chamber. For each plant type, they noted which VOCs the plants took up, how quickly they removed these VOCs from the air, and how much of the VOCs were ultimately removed by the end of the experiment.

 

The researchers tested five common house plants and eight common VOCs, and they found that certain plants were better at absorbing specific compounds. For example, all five plants could remove acetone—the pungent chemical that is abundant at nail salons—from the air, but the dracaena plant took up the most, around 94 percent of the chemical.

This plane's bathroom cleans itself with UV lights | Sustainable Innovation | Scoop.it

Plane toilets are cramped, tiny and unavoidable -- and they're certainly not clean. But Boeing think they have a solution -- self-cleaning bathrooms.

Boeing's team of engineers and designers have developed a room with the ability to kill "99.99 percent of pathogens". It does so by combining touchless faucets, flushes and soap dispensers, which many of us are already familiar with, with a newer type of cleaning technology -- UV light.

This new facility is turning exhaust fumes into liquid fuel | Sustainable Innovation | Scoop.it

A test facility in China has successfully converted exhaust emissions into oil, pointing to the possibility of turning the tonnes of harmful gases emitted by power stations, steel mills, and garbage dumps each year into something we can actually use.

"We have pieced the system together into an integrated system, where you put gas in one end and get a liquid fuel out of the other end," one of the team, Gregory Stephanopoulos from MIT, told The Guardian.

Saurea : une nouvelle invention inusable, super économique et ultra écologique pour le futur

Saurea : une nouvelle invention inusable, super économique et ultra écologique pour le futur | Sustainable Innovation | Scoop.it
Voici un moteur, nouvelle génération, sa fonctionnalité est tout aussi simple : pas de carburant, ne nécessite aucun entretien et sa durée de vie est génialissime (25 ans sans aucun arrêt) soit un quart de siècle. Une invention spectaculaire qui vient à son heure et qui apportera au secteur de l'énergie un plus. Le français Alain Coty a du vraiment se triturer les méninges, pour mettre sur place un tel outil. Il a pioché dans tous les coins pour une telle performance.

 
Ce dernier a mis au point un moteur unique capable de transformer l'énergie solaire en puissance motrice. Par ailleurs, l'objet ne comporte aucune pièce d'usure, ni composant électronique. Le moteur n'a pas besoin ni d'assistance, ni d'intervention humaine. En tout cas, l'ingénieur français est allé très loin.Cet exploit sera justifié par cette phrase : « On met ce moteur au soleil, il se met à tourner, on revient 25 ans après, et il tourne toujours. »

 
L'engin baptisé, Saurea sera vite adopter surtout dans les pays très ensoleillés, ainsi il trouvera sa place dans le pompage de l’eau souterraine (puits), à l’irrigation, à la mécanisation agricole et artisanale, au chauffage, au refroidissement, à la ventilation, au traitement de l’eau. Une vidéo a été mise en place pour vous permettre de mieux vous imprégner de Saurea, un moteur à l'imagination fertile et débordante.

This new material pulls clean drinking water straight out of the air

This new material pulls clean drinking water straight out of the air | Sustainable Innovation | Scoop.it

One of the ways of sourcing drinking water in areas afflicted by drought is by harvesting it from the air, and now a new material developed by scientists in the US could make this tricky feat easier than ever.

Researchers at Harvard University have taken inspiration from a variety of water-collecting traits in different natural species to develop what could be an unrivalled composite system for harvesting and transporting atmospheric H20.

 

"Everybody is excited about bio-inspired materials research," said chemical biologist Joanna Aizenberg from Harvard's Wyss Institute for Biologically Inspired Engineering. "However, so far, we tend to mimic one inspirational natural system at a time."

This could solve a lot of problems.

Scientists in Canada have developed a new method of growing human tissue outside the body, creating a miniature lattice structure that's capable of providing an external matrix for living cells.

Called AngioChip, the researchers say their 'person on a chip' technology could be a new platform for testing the effects of drugs on human tissue, with the mini 3D scaffold constituting a more realistic environment for growing cells than the flat layout of a petri dish.

Bill Gates is backing a waterless toilet that generates energy from human waste | Sustainable Innovation | Scoop.it

Five years after the Bill and Melinda Gates Foundation first challenged the world to design a sustainable and inexpensive toilet, researchers from Cranfield University may have a viable contender. It’s known as the Nano Membrane Toilet, and it was funded by the Gates Foundation in September 2012 for US $710,000.

March 22 is World Water Day, an appropriate time to highlight the grim fact that more than 2.4 billion people around the world still live in unsanitary conditions. Without access to clean running water, these at-risk communities face life-threatening sanitation-related diseases.
