- jacquesm 9y agoThe difference is that the frequencies required for wireless charging are typically much lower if the coupling is magnetic. The 'wireless' form in the article is more akin to what a trolleybus would use and likely would not survive for long in the presence of either a large amount of traffic (more demand than the rail could handle, imagine a traffic jam) or arcing as well as danger to the public (think subway third rail). I do not think this concept will survive in the long term.
- rsynnott 9y agoThis one isn't wireless; there's an arm descending from the vehicle.
- bluGill 9y agoI'm sure people will fear this too. Driving by the same people who probably will make a ton of money speaking about how bad it is for you. Of course in both cases that science says there is no harm is best shouted down.
- JPLeRouzic 9y agoI would comment only about the wireless charging case: In medicine there is a wireless device to treat an aggressive form of brain cancer: TTFields. It is approved by the FDA [0] It works by disrupting microtubules in the cell, a kind of micro-skeleton that gives its shape to the cell. The TTFields electrical fields have a low frequency, very similar to the Qi wireless charging standard.
