The development of new oceanographic sensor platforms such as seafloor cabled observatories and autonomous vehicle networks, and with the miniaturization of oceanographic sensors ranging from mass spectrometers to 4K video systems, the prospects for doing science in the deep ocean have never been brighter. The difficulty of powering systems in the ocean for long time periods or with high power requirements has limited the ability of deep-ocean scientists to capitalize on recent sensor and sensor system advances. To resolve this problem the PI proses to design, build, and test a small thermoelectric power device that will use geothermal heat from hydrothermal vents to generate electricity, charge batteries, and power small seafloor instruments indefinitely. The availability of such a system could enable the development of seafloor ?power stations? where autonomous vehicles charge their batteries.The development of a hydrothermal thermoelectric power module could enable the development of an entirely new kind of seafloor observing network that could revolutionize the ocean sciences by providing a "platform of presence" anywhere in the deep ocean where strong thermal gradients can be found or created.

海底电缆观测站和自动驾驶车辆网络等新型海洋传感器平台的发展，以及从质谱仪到 4K 视频系统等海洋传感器的小型化，深海科学研究的前景从未如此光明。长时间为海洋中的系统或高功率需求供电的困难限制了深海科学家利用最新传感器和传感器系统进展的能力。为了解决这个问题，PI 着手设计、建造和测试一种小型热电发电装置，该装置将利用热液喷口的地热来发电、为电池充电并无限期地为小型海底仪器供电。这种系统的可用性可以促进海底“发电站”的开发。水热热电发电模块的开发可以实现一种全新的海底观测网络的开发，通过在深海任何有强热力的地方提供一个“存在平台”，可以彻底改变海洋科学。可以找到或创建渐变。
