Photovoltaic is not cheap and it is not clean. It in fact has a larger carbon footprint than fossil fuels alone. That is fundamentally because the PV cell takes more energy to manufacture than it will ever return during its entire service lifespan. That trade off is certainly acceptable in space, and the PV cell was first used to power the Vanguard satellite in 1959 for that reason.

“Applying a 3.6% cloud reflectivity perturbation to the shortwave energy balance partitioning given by Trenberth et al. (2009) corresponds to an increase of 2.7 Wm⁻² of solar energy reaching the Earth’s surface and an increase of 2.4 Wm⁻² absorbed by the surface.” – Title: ‘A net decrease in the Earth’s cloud, aerosol, and surface 340 nm reflectivity during the past 33 yr (1979-2011)’ Author: J.

This article provides information about the selection of SSVs in all chemical process industries (CPI), but focuses on metallurgical processes and applications, and offers examples to illustrate both the successful and unsuccessful use of this type of valve. The intent of the article is to raise the awareness of SSV considerations for all industry stakeholders, including suppliers and manufacturers, specifiers and users, as well as owners. The article also supplies tools to better understand where and why SSVs shoud be categorized separately from commodity, or general purpose valves (GPVs).

The recent spill at TCC is a prime example of infiltration, water getting into a manhole and forcing it to backflow.
