Wildfires cause catastrophic damage worldwide, accounting for 20% of global carbon emissions. The problem, exacerbated by climate change, is deteriorating. Unusually severe fires in USA, Australia, Spain etc, have claimed hundreds of lives, causing damage worth US$Bn's. Wildfires are breaking out in countries unaccustomed to the problem. Northern European countries experienced a 200x increase in area burned in 2018\. Even the UK is being badly affected (e.g. Winter Hill -- 2018).We propose a new solution for early detection of the most predictable fires: those occurring due to power line failure - more damaging than most because they often occur in high winds. In California over 6 years, 1,500 wildfires started in the power line corridors of one utility company, some of the most devastating on record. In Spain, 3,185 fires were started by power lines between 1985-2010\. Power line operators worldwide now face severe financial liabilities (US$Bns), creating a large market (£M100's) for reliable and effective detection systems.Utility companies have assessed sensors (based on visible/thermal imagers) but have not adopted any at scale because they are too expensive to rollout, require human monitoring and only detect fires once they have grown to an unstoppable size. Companies need technologies that can detect fires in the first minutes after ignition, while they still occupy <1 acre and when firefighters have a chance of extinguishing the fire before it causes extensive damage. This is challenging. Many wildfires occur in remote areas far from electricity and telecommunications infrastructure, so low power consumption, reliability and power/comms-autonomy are key.The sensing system we propose will use low cost, world-leading pyroelectric infra-red (PIR) detectors (Pyreos) with low cost, highly-efficient non-imaging radiation-collectors (Tethir). PIR's are widely used in fire/flame detection systems for the oil-and-gas sector. Tethir's optics will give a usable detection range (1-2km) with existing detector performances and much further with the development of better detectors. The project will develop a saleable market-entry product and we predict sales of £M10's to power companies over the first 5 years after prototype demonstration, with further sales as we extend the detection capability to other wildfire causes (e.g. arson). The combination of cutting edge technologies with two world-leading UK experts in PIRs and wildfires at Imperial and Kings College London is key to the success of this development and brings the UK a significant wealth-creation opportunity while helping to solve a serious world-wide problem.

野火在全球造成灾难性损害，占全球碳排放量的20％。气候变化加剧的问题正在恶化。在美国，澳大利亚，西班牙等异常严重的大火夺去了数百人的生命，造成了价值$ $ $ $的损失。野火在不习惯这个问题的国家中爆发。北欧国家在2018年燃烧的面积增长了200倍。即使是英国也受到严重影响（例如，冬季 - 2018年）。我们提出了一种新的解决方案，用于早期发现最可预测的火灾：那些由于电力线故障而发生的那些 - 比大多数人经常发生在大风中更具破坏性。在加利福尼亚州6年以来，一家公用事业公司的电力线走廊开始了1,500起野火，这是有记录以来最具破坏性的。在西班牙，1985年至2010年之间的电力线发动了3185次大火。 Power line operators worldwide now face severe financial liabilities (US$Bns), creating a large market (£M100's) for reliable and effective detection systems.Utility companies have assessed sensors (based on visible/thermal imagers) but have not adopted any at scale because they are too expensive to rollout, require human monitoring and only detect fires once they have grown to an unstoppable size.Companies need technologies that can detect fires in the first点火后几分钟，虽然他们仍然占据<1英亩，而消防员有机会在造成广泛损害之前扑灭大火。这是挑战。许多野火发生在远离电力和电信基础架构的遥远地区，因此低功耗，可靠性和功耗/通信/自治是关键。我们建议的传感系统将使用低成本，领先的pyroelectrictresure（PIR）检测器（PYREOS（PYREOS）具有低成本，高成本不高的非成本效果，高效的散热仪）。 PIR被广泛用于油气领域的火/火焰检测系统中。 Tethir的光学元件将提供可用的检测范围（1-2公里），并具有现有的检测器性能，并随着更好的检测器的发展而进一步。该项目将开发可销售的市场入门产品，我们预测在原型演示后的头5年中，M10英镑的销售额将向电力公司销售，随着我们将检测能力扩展到其他野火原因（例如纵火）。尖端技术与两位世界领先的英国PIR和野火专家在伦敦帝国和国王学院的野火方面的结合是这一发展成功的关键，并为英国带来了一个巨大的创造机会，同时帮助解决了一个严重的全球问题。
