CleanSpace CO Sensor Runs On Freevolt RF Harvesting

Posted by BeauHD on from the nothing-is-free dept.

mspohr writes: A few years ago, a Kickstarter was set up to develop a locator tag powered by free radio frequency (RF) energy harvested from the environment. This was called a scam here on Slashdot and was shut down before it was funded on Kickstarter. However, it now appears that the concept is not as far-fetched as some predicted. A UK company CleanSpace has developed a carbon monoxide (CO) sensor which is powered by free RF. A review of the product has been posted on YouTube. It uses Freevolt technology to keep a battery charged and the CO sensor running. Since they have several thousand of these devices collecting data, they do appear to work and it seems to be in the 'not a scam' department.

    But isn't it also very limited by how many people try to do the "RF Energy Harvesting"? and line of sight? The guy 'behind' the other one who did the RF harvesting won't have as much energy to harvest..

    If it notifies a powered device, the powered device can sound the alarm.

    A lot of time, the benefit of wirefree power isn't power savings, it's the saving of installation cost of wires, or replacement labor on batteries.

    You don't sell it to make money, you sell it to piss them off.
