Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Light barrier used to repel mosquitoes

RATE THIS! +1
Posted in Medicine on 15th Nov, 2011 10:23 PM by APM

You're in the middle of a great chat with friends on a warm summer night, and then "ouch" a mosquito interrupts your conversation with a bite on your forearm. Experimental physicist Szabolcs Marka hopes to make this occurrence a thing of the past, but in this case it's not aerosol spray or roll-on-repellant keeping the bugs at bay, it's a wall of light.

 

Marka is working on a project that uses infrared light to form a barrier between humans and mosquitoes, as well as other common insects such as moths and wasps. The theory is that you can use light to form a wall that separates space. In a phenomenon not fully understood, the mosquitoes that are outside the wall seem blocked, as if by a semi-invisible fence.

 

"The mosquitoes are probably scared," Marka explained to Forbes. "They could go through the light barrier without getting hurt, but they don't. That's the beauty of it because you don't have to necessarily kill them. You just make them go away."

 

The technology is a simple one. A standard laser pointed in the direction of your choice to block the entryway to your home, or outdoor space. "Light is very easy to manipulate and shape to many geometrics with optics," says Marka.

 

Incidentally, laser-powered help might also be on the way for those who do want to put a dent in the mosquito population.

 

Szabolcs Marka was given US$100,000 in seed money for his idea in 2008, as well as a $1,000,000 donation from the Bill and Melinda Gates foundation through the Grand Challenges Exploration grant.

 

The science has far-reaching implications in mosquito-ridden areas where malaria is prevalent. In Uganda alone, malaria is responsible for approximately 20-percent of all childhood deaths.

 

While a prototype for the mosquito repellant is probably several years away Marka's team is studying the effects of different types of light, as well as the intensity, color, and shapes that can ward off not only mosquitoes, but moths, wasps, and even bed bugs.

 

Cost figures don't exist just yet, but one would have to assume that simple laser technology wouldn't be cost-prohibitive

Dec21 Just about all of what you state happens to be susiipprngly precise and that makes me ponder the reason why I hadn't looked at this in this light previously. This piece truly did turn the light on for me personally as far as this specific issue goes. However there is actually 1 point I am not too comfy with so while I attempt to reconcile that with the core theme of your position, permit me observe exactly what all the rest of your subscribers have to point out.Well done.

Glass shops use a special resin that is applied into the crack using suction cup mounted injection system. The resin is then cured with an ultra-violet light for a strong and safe renria.Geperally speaking, a reputable shop will not attempt to repair a crack that is either in the driver’s direct vision or anything larger than a dollar bill. You’re probably looking at having to replace the windshield. Depending on the vehicle, your costs will range anywhere from under $ 200 to over $ 500. Super glue will NOT do the trick! Reply
