Comment who will change batteries? (Score 1) 51
as you read in the article:
"... Each node is smaller than a human fist and powered by batteries and solar panels....
The sensors are positioned within tens of metres of each other and communicate through Wi-Fi and Bluetooth..."
knowing that neither Wifi, nor bluetooth are very efficiently dealing with the powerconsumption, i wonder who will be changing the batteries of these sensors every so many months.
