Heard this story on the radio and thought of boyfriends past who were SO into StarWars; perhaps they are still… It was all about the Rebel Forces, and how the Death Star pulled them in – but I digress…
“Sci-fi” references aside, this is genuine Tractor Beam Technology that is currently being explored by scientists in Australia. News has been released that physicists at The Australian National University (ANU) ‘have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach‘.
Here’s three takes on the subject:
P.S. I hear the surfing is great down under. Maybe you want to head off and join the Aussies to do some water research…
As a follow on to the Vertical Farms blog post by Kimberly (published August 6th), read about this Thesis project from Philipp Hutfless who’s studying Industrial Design at University of Applied Sciences in Darmstadt, Germany. He was inspired by a trip to Japan which sparked his desire to design a food system that could be sustained offshore.
Here’s a sketch of his work in his own words on the
James Dyson Foundation website:
Another description of the project is posted on the Fast Company exist website (They have all kinds of reviews, musings, op ed pieces and product information on their site – check it out) Floating Ocean Greenhouses Bring Fresh Food Closer To Megacities
As we all droop from the heat of summer in America, it’s a depressing thought to imagine that water shortages could spell an end to making lemonade or running thru the sprinkler on your lawn or hanging out at a pool or beach with your friends or biting into a sweet juicy peach grown by a local farmer (all particularly summer-y type activities that are generally associated with the U.S.). But it may not be as far fetched as one might suppose - and it may have a financial repercussions worldwide, too!
Since 2011 companies have spent more than $84bn worldwide to improve the way they conserve, manage or obtain water, according to data from Global Water Intelligence, regulatory disclosures and executive interviews with the Financial Times.
Please take some time to check out the article by Pilita Clark linked below . Admittedly, it’s a lengthy read, but absolutely fascinating (and slightly terrifying!) in the details about the many areas of the globe that have already begun preparations in hopes of staving off the worst effects of the ‘evaporation’ of this most precious commodity.
(P.S. Note her mention of Coca-Cola and their project with World Wildlife Fund – I talked about their work in my blog post on June 27th. Here’s another chance to click on the panda to explore different career paths for yourself)
Inspired by the wings of desert beetles, a new device made of millions of tiny carbon tubes could one day be used to pull water from the air — even from the most arid desert air in regions where such a device would be especially useful.
The amount of water vapor captured depends on the humidity of the air. The new water collection device doesn’t require any external energy, but the production costs of carbon nanotube arrays continues to be a bottleneck.
At the University of South Florida, students and staff are working through research to create a more sustainable earth. Fertilizer needs to be reinvented if it is to be as effective as it should be healthy for the planet. Conventional fertilizers need to be replaced.
The fertilizers that we are sustainably creating through our system at USF, offset need to create conventional fertilizers. Conventional fertilizers require mining of important nutrients such as phosphate, which generates extremely harmful environmental impacts and often creates wastelands on the mine site. Places such as Florida (where we are located) have large expanses that have become these wastelands. Furthermore, worldwide phosphorus deposits are depleting (just as oil deposits are depleting). Our system allows for recovering nutrients such as phosphorus from waste, turning that waste into a valuable resource. Therefore, it creates a renewable source of nutrients and reduces the need to have harmful phosphate mining operations. Furthermore, creating Nitrogen fertilizer, which is typically done through the Haber process, uses large amounts of energy and incurs high costs.
Not only are our fertilizers created sustainably using renewable source, but they also are expected to outperform conventional fertilizers in several ways that are important to the environment. For example, our fertilizers are expected to have slow-release characteristics, meaning that they dissolve slowly, allowing for the plants to uptake the nutrients efficiently. Conventional fertilizers dissolve very quickly, causing most of the fertilizer to be washed away by rain. The fertilizer nutrients that are washed away cause very harmful environmental impacts such as eutrophication, which often leads to hypoxia or “dead zones” (complete depletion of oxygen in the water) that cause mass death of aquatic life such as fish and crabs. This is a common occurrence in the Gulf of Mexico, where nutrients are carried into it by rainwater runoff, causing massive dead zones and loss of life.
Our slow-release, sustainable fertilizers can significantly reduce the instance of these fish kills. However, our growth study is needed to prove that our fertilizers can compete with conventional fertilizers. This will prove that these sustainable fertilizers can be widely adopted while still providing the same performance as conventional fertilizers.
