Are you slowly killing your houseplants? Probably! But there might be a reason (other than neglect) why they’re all yellow and wilty: your Wi-Fi router.

An experiment by a handful of high school students in Denmark has sparked some serious international interest in the scientific community.

Five ninth-grade girls at Hjallerup School in North Jutland, Denmark, noticed they had trouble concentrating after sleeping with their mobile phones at their bedsides. They tried to figure out why. The school obviously doesn’t have the equipment to test human brain waves, so the girls decided to do a more rudimentary experiment.

They placed six trays of garden cress seeds next to Wi-Fi routers that emitted roughly the same microwave radiation as a mobile phone. Then they placed six more trays of seeds in a separate room without routers. The girls controlled both environments for room temperature, sunlight and water.

After 12 days, they found the garden cress seeds in the routerless room had exploded into bushy greenery, while the seeds next to the Wi-Fi routers were brown, shriveled, and even mutated. See for yourself:

Teacher Kim Horsevad told the Daily Dot that her students did the test twice with the same results. She was quick to point out that while the students did the experiment to test only one variable to the best of their ability, it is a high school experiment and this isn’t a professional study…

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.
