It's enough to make you cry." On the other side of the small road that winds along his property, a short distance from the town of Mazeyrat-d'Allier, in the Haute-Loire department, Frédéric Salgues can spot what he considers to be the cause of his cows' problems, less than 300 meters away: a cell phone tower commissioned by Orange on June 28, 2021.[...] On May 23, the administrative court of Clermont-Ferrand ordered the 4G antenna's cessation of operation for a period of two months.This measure, unprecedented in France, should become effective within three months. The objective is to carry out an expert assessment in order to "establish a potential causal link between the behavior of the cattle and this antenna." The administrative court highlights "a significant drop in the quality and quantity of milk produced, a serious disruption in the behavior of the herd and its voluntary denutrition and abnormally high deaths.Original SubmissionRead more of this story at SoylentNews.

upstart writes:The Weird World Of Liquid Cooling For Datacenters:When it comes to high-performance desktop PCs, particularly in the world of gaming, water cooling is popular and effective. However, in the world of datacenters, servers rely on traditional air cooling more often than not, in combination with huge AC systems that keep server rooms at the appropriate temperature. However, datacenters can use water cooling, too! It just doesn’t always look quite how you’d expect.Cooling is of crucial importance to datacenters. Letting hardware get too hot increases failure rates and can even impact service availability. It also uses a huge amount of energy, with cooling accounting for up to 40% of energy use in the average datacenter. This flows into running costs, as well, as energy doesn’t come cheap.Thus, any efficiency gains in cooling a datacenter can have a multitude of benefits. Outside of just improving reliability and cutting down on emissions through lower energy use, there are benefits to density, too. The more effective cooling available, the more servers and processing power that can be stuffed in a given footprint without running into overheating issues.Water and liquid cooling techniques can potentially offer a step change in performance relative to traditional air cooling. This is due to the fact that air doesn’t have a great heat capacity compared to water or other special liquid coolants. It’s much easier to transfer a great quantity of heat into a liquid. In some jurisdictions, there is even talk of using the waste heat from datacenters to provide district heating, which is much easier with a source of hot liquid carrying waste heat vs. hot air.However, liquid cooling comes with drawbacks, too. Leaks can damage electronics if not properly managed, and such systems typically come with added complexity versus running simple fans and air conditioning systems. Naturally, that improved cooling performance comes at a trade-off, else it would be the norm already.Read more of this story at SoylentNews.
