Life Cycle Assessment of 2022 Laptop

September 20, 2023 by kris de decker Filed Under: Computers, Random

Laptop manufacturer Framework commissioned Fraunhofer IZM to do a detailed life cycle analysis on their Framework Laptop 13, which is designed to be upgradeable, repairable, and customizable. The functional unit used in the study is the use of this notebook over 5 years. Although the laptop is modular and repairable, no product failure and thus no repair was assumed. The configuration was assumed to include 16 GB of memory, 256 GB of storage, and two expansion cards with USB-A and USB-C connectors.

Unfortunately, the researchers only calculate the environmental footprint of the laptop in terms of global warming potential and resource depletion, not energy consumption. Nevertheless, the study is interesting for its detailed breakdown of components, with the display and the electronic circuits responsible for the largest environmental damage. The total impact for the Framework Laptop is estimated to be 200 kg CO2e. Almost 70% of this is due to the production phase.

Untangling the Mystery of the World’s First Rooftop Solar Panel

August 18, 2023 by kris de decker Filed Under: History, Random, Solar

“In 1909, inventor George Cove posed in front of an early rooftop solar panel of his own design for a photograph. One hundred and ten years later, the resulting image was reprinted in the official journal of the US’ most prestigious research institute – but Cove was nowhere to be seen.

Using a range of sources such as newspaper archives and historic city maps, Bellingcat sought to establish the seeming mystery of Cove’s ‘disappearance’ from the photograph. This analysis of archival material from the pioneering days of solar energy tells a cautionary tale about the ease of misattributing historic photos.”

Ticket prices of planes versus trains in Europe (pdf). [Greenpeace] “By analysing 112 European routes and comparing air and rail fares on 9 different days for each route, this report shows the extent to which European citizens are being encouraged to fly. It also identifies the reasons for these outrageous price differences and proposes solutions to make rail competitive on all routes.”

The relationship between cycle track width and the lateral position of cyclists, and implications for the required cycle track width. [Journal of Safety Research] “Given a cyclists’ lateral position while meeting, common variations between cyclists’ steering behavior, and vehicle width and circumstances, a cycle track width of 250 cm is needed for safe meeting maneuvers.”
