 with eight power and who are you? My name is Paul Egan and I'm VP of Business Development for eight power. And what are you showing here? What is this? So today we are launching our self-powered GPS tracker. So we are using vibration energy harvesting and a mixture of solar to be able to run a sensor network with enough power to run GPS as well as wide area communications over the new low-power wide area networks. So this is energy harvesting 100% Yep so this is completely self-sufficient when it comes to energy. We use vibration from the environment such as when attached to a truck or a piece of rotating machinery or maybe on a rail freight car. That generates some of the power but obviously we can supplement that with high-efficiency solar cells as well. And your company have you been doing this for a while or what do you talk about in your right here? Sorry let me jump in. What is this about on the bridge? So this is a case study of a self-powered sensor that we ran on the fourth road bridge in Scotland in 2015. So this was to prove the concept that just by attaching one of our devices to a vibrating structure it meant that we can generate enough power to run a sensor system and run the wireless. So this is real? This is real yeah. Are you actually out there in the market? Yep these are real products. The first prototype devices are going to be sold at the end of June with production in the fourth quarter this year. So how much of the power comes from vibration? How much from the solar? Most of it says for the applications we've seen so far most of it says you're coming from vibration. And is this size like this? It's called a track 100 SA. Yep. It's using Laura 1. Yep we're using Laura 1 for this particular one because we have a Laura network with us in Berlin today but we do support all the other low-power wide-area standards such as LT, CAT M1 and narrowband IoT. So potentially you would want to have millions of these everywhere or what's what's going to happen in the future? Yeah ideally so for us the business model is sensing as a service so rather than just being a straight hardware play we would see being able to provide services over a number of years to assets particularly the kind of assets where you would install the device and then never have to go back and change the batteries or recharge the device. Are you planning to do smaller ones? You have small ones? Yeah we have this is our launch the first launch product we are planning on a range of other devices with different power outputs different sensors and with different wireless systems. So on the bridge is the cars that go on a bridge to make it a wood? Yep it was just literally the bridge itself resonates and we attached one of our harvesters to the one of the parts that vibrate so that was enough to provide the power to run the wireless and the sensing.
