RCA Airnergy Charger Harvests Electricity From WiFi Signals

This thing is, seriously, the highlight of CES for me (so far) this year. 3D TVs and eBook readers are fine, but there’s nothing amazing about them.  The Airnergy Charger is amazing. This little box has, inside it, some kind of circuitry that harvests WiFi energy out of the air and converts it into electricity. This has been done before, but the Airnergy is able to harvest electricity with a high enough efficiency to make it practically useful: on the CES floor, they were able to charge a BlackBerry from 30% to full in about 90 minutes, using nothing but ambient WiFi signals as a power source.  The Airnergy has a battery inside it, so you can just carry it around and as long as you’re near some WiFi, it charges itself. Unlike a solar charger, it works at night and you can keep it in your pocket. Of course, proximity to the WiFi source and the number of WiFi sources is important, but at the rate it charges, if you have a home wireless network you could probably just leave anywhere in your house overnight and it would be pretty close to full in the morning.

Here is the really, really unbelievable part: RCA says that the USB charger will be available this summer for $40, and a battery with the WiFi harvesting technology will be available soon after. I mean, all kinds of people are pushing wireless charging, but this would hands down take the cake… It doesn’t need a pad and it’s charging all the time, for free, in just about any urban environment.

Green products contain hidden toxic chemicals

Tests Find Toxics in Broad Array of Consumer Products:

 

Toxic chemicals linked to the rising rates of endocrine disruption related disease were found in a broad array of consumer products and reported in a peer reviewed article in Environmental Health Perspectives on March 8. The Silent Spring Institute tested 213 consumer products, including cleaning products, cosmetics, sunscreens, shower curtains, air fresheners, drier sheets, and other household goods made by Colgate, Unilever, S.C. Johnson, Johnson and Johnson, Procter & Gamble, Seventh Generation, and Ecover among other manufacturers.  “These test results show that both conventional and so-called green products contain hidden toxic chemicals that are not on product labels—so consumers have no way of avoiding them,” says Alexandra Scranton from Women’s Voices for the Earth, who recently conducted their own tests for hidden toxic chemicals in 20 top brand-name cleaning products. “Companies need to phase out these harmful chemicals, and we need a policy that standardizes labeling guidelines for cleaning products, so companies can’t keep these toxic chemicals a secret.”  Environmental health advocates across the nation see this new study as confirmation that ubiquitous chemical exposure is playing a factor in adverse health impacts.  “Silent Spring used Battelle Labs in Ohio, and they found 55 chemicals associated with endocrine disruption or with asthma, including parabens, BPA, triclosan, Alkylphenols, cyclosiloxanes,” said Martha Arguello, with Physicians for Social Responsibility—Los Angeles. “It is not good science to assume that cumulative exposure to these chemicals is safe.”  “This new study found PVC products, including a pillow protector and shower curtain, contained high levels of the toxic phthalate DEHP,” said Mike Schade from the Center for Health, Environment & Justice. “Phthalates have been banned in toys, but are widespread in many PVC products children coming in contact with in schools and even at home. Phthalates have been linked to asthma, adverse impacts on brain development, and reproductive health problems in baby boys. Thankfully, there are safer cost-effective alternatives to phthalate-laden PVC products for our schools and homes.”  “Many  products are targeted to women of color who suffer from high health disparities that can be linked directly to the endocrine disruptors found in these products. We can only hope that studies like this one inspire better policies and regulations of these dangerous chemicals,” said Janette Robinson-Flint from Black Women for Wellness. “Mother’s shouldn’t have to be a biochemist to protect themselves and their families from toxic chemicals in everyday products.” “We know many folks have tested positive for BPA and Triclosan in our human Biomonitoring studies,” said Sharyle Patton, director of the Biomonitoring Resource Center at Commonweal. “One has to wonder if rising rates of  associated health problems  are linked to these exposures.”  Caroline Cox, research director, Center for Environmental Health, said, “These unnecessary, untested and unlabeled chemicals in dozens of everyday products threaten our children’s and families’ health. It’s past time for federal action that calls for evaluating chemicals for safety before they end up contaminating our homes and our bodies.”  “This is another example of the failure of federal law to protect workers and consumers,” said Sarah Doll from SAFER States. “States have been acting to protect consumers from toxic chemicals in products for years now, and will continue to move on these issues in the absence of federal reform.”  The products were tested in 2008, and the study authors acknowledge that product samples can vary and that some formulations may have changed.
