Hydroelectricity and transmission planning in Chile use open source geospatial tools
From 2014 and 2017, I had the good fortune of working with a multidisciplinary team in Chile, building decision support tools to facilitate the planning of hydroelectric capacity as an alternative to fossil-fuel based thermoelectric capacity. Our job was also to aid in the design of transmission line corridors. Transmission lines carry “bulk electricity” from where the electricity is generated to where it is consumed. Those lines are strung from towers that are placed within transmission corridors, where vegetation and access are managed for safety. In many countries, the location of these corridors is carefully planned in order to take into account engineering feasibility as well as social, cultural, environmental and other economic factors.
Earlier, I wrote about the hydroelectric capacity planning exercise, but the transmission corridor planning projects came along later, and in the context of those projects, we learned more about the valuation framework we used and about how open source software provided great solutions for scenario generation and testing and general trade-off analysis. I’ll revisit those details here.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
