Solar and Wind Energy in One Device to Power IoT

Solar and Wind Energy in One Device to Power IoT

It’s a revolutionary new concept that could change the way you look at energy generation and IoT.

Scientists have integrated a solar cell and a nanogenerator that can convert wind energy into electricity in a single device, according to the Financial Express. The goal is to effectively power the Internet of Things (IoT)–smart locks, lights, security systems, thermostats and more.

The solar cell component of the system delivers 8 milliWatts of power output. One milliWatt can light up 100 small light-emitting diodes (LEDs), researchers tell Financial Express. The wind harvesting component delivers up to 26 milliWatts. Together, under simulated sun and wind conditions, four devices on the roof of a model home could turn on the LEDs inside and power a temperature-humidity sensor.

This new concept couldn’t have come at a better time. Gartner Research is forecasting that 6.4 billion connected things will be in use worldwide in 2016. That’s up 30 percent from 2015. The firm also estimates that IoT will support total services spending of $235 billion in 2016. That’s up 22 percent from 2015.

All of these machines will require a lot of energy.

Rather than adding to the global reliance on fossil fuels to power the network, according to Financial Express, researchers say they can be powered by a single device that harvests wind and solar energy.

The findings were published in the journal ACS Nano.

    How can they claim that 1 milliwatt can power 100 small LEDs? Even a small indicator LED consumes about 10 mA @ 1.5 V, that is 15 milliwatts for a single LED.
