Tenkiv developed a new kind of solar power system focused on cost-effectiveness and scalability in need of data acquisition system to collect and analyze data from different sensors throughout the cloud. Because the system may have different energy conversion devices (modules), different number of thermal circuits, collectors, etc. the control software has to be very adaptable to match these varying configurations. Therefore the JVM was an ideal choice. The control software "Nexus Brain" is written in Kotlin. It heavily uses Units of Measurement, so Tenkiv created Physikal, a Kotlin extension to the Java 8 implementation of JSR 363. A project also used by others, for example in collaboration with NASA or ETH Zurich. This session will give a brief overview of how Tenkiv and Nexus Brain use Kotlin and Physikal/JSR 363 to calculate the optimal usage of alternate energy sources and control solar power systems for making clean water anywhere from Flint Michigan to Afghanistan or Cape Town.
