to prevent forest fires from taking hold in the first place. it s conventional wisdom that the earlier forest fire can be stopped the better, but often a fire can already be well established before it is noticed, making it harder to put out. but one company in germany believes it has a possible solution by using internet of things, sensors and alto understand what forest fires smell like. the basic function is like an electronic nose that we put into the forest and it can actually smell a fire. we can detect fires during the smoldering phase. so a few minutes after someone has thrown a cigarette, we should be able to ring the alarm bells. every forest fire has a unique aroma based on what surface material is around. i love that smell. yes. their forest ecology expert, dr. juergen mueller, collects these samples from around the world and then burns them to generate the data to train the ai on what an actual fire in a specific location may smell like. ok, now, we closed the cha
the sensors every 100 meters in more remote areas and 15 meters near well walked paths. so it looks like quite a lot of smoke coming off there. would that be enough already for your sensors to to be able to detect? that is enough for our sensors. so this smoke needs to reach the sensors, that means if the sensor is close to the smoke, for example, on this tree, then you have it within seconds. but it s notjust the eye and the sensors that are innovative. there s another problem that needed solving. we re here in a forest, in a rural area where i imagine there isn t much mobile signal. how do you get the data from the sensors out to where it needs to go to? because mainly there is no internal telecommunication infrastructure in the forest, we bring our own telecommunication infrastructure to the forest. so this is the mesh gate. oh, wow. okay. yeah. these mesh gateways needs to hear over the air. if one of these sensors in the forest has an alarm or a signal and so on, and the
hampshire, and iowa. the question is how strong is that lead with the other things that he has going on in his life, his legal life? ainsley: he leads 30 to 40 points in most of the national polls. look at his fundraising, brian, 54 million fundraiser first half of the year. and then higher than any other campaign, so, he has got a lot of money to spend on the ads and to be able to travel around state to state. brian: a lot goes to his legal fees and i think his supporters understand that next look who is on the rise. first off. we have ron desantis, he has been a solid number two. and he was a lot closer to trump before the legal cases started and the indictments started cascading down. he had to revamp, fire some people, reconfigure his staff a little. he thinks he? a good place right now. is he number two. ainsley: yeah. and then number three, according to the power ranchings, keep in mind the power rankings, the model is comprised three factors, polling averages, considers th
