Submission + - 40,000 Chromebooks and 9,600 iPads Go Missing at Chicago Public Schools

theodp writes: "When the school system [Chicago Public Schools] shifted to having students learn remotely in the spring of 2020 near the beginning of the pandemic, it lent students iPads, MacBooks and Windows computer devices so they could do school work and attend virtual classes from home," reports Frank Main in the Chicago Sun-Times. "CPS then spent about $165 million to buy Chromebook desktop computers so that every student from kindergarten through senior year in high school who needed a computer could have one. Students borrowed 161,100 Chromebooks in September 2020. By June 2021, more than 210,000 of those devices had been given out. Of them, nearly 40,000 Chromebooks have been reported lost — nearly a fifth of those that were lent. 'Schools have made repeated efforts to recover the lost devices from families without success,' according to a written statement from CPS officials in response to questions about the missing school property. Also missing are more than 9,600 iPads, 114 televisions, 1,680 printers and 1,127 audiovisual projectors, among many other items. Officials say CPS has bought new computer devices to replace the missing ones."

There were 340,658 students enrolled in the Chicago Public Schools (CPS) at the start of the 2020-2021 school year.

Submission + - SPAM: Carbon-coated nickel enables fuel cell free of precious metals

schwit1 writes: “A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, Cornell University researchers have found. The new discovery could accelerate the widespread use of hydrogen fuel cells, which hold great promise as efficient, clean energy sources for vehicles and other applications.”

Comment Power Line Communication... (Score 0) 83

When I first seriously started thinking of smart grid applications back in 2002... this is what I thought they would be using...

Why implement a step back in tech when they could do BPL? Seems like it is drastically more realistic(see cheaper) in implementation than a wireless network.

Race Car Made With Veggies And Powered By Chocolate 83

IS4110 writes "A new racing car made with potatoes and carrots and powered with chocolate waste has been developed by the Innovative Manufacturing Research Centre of the University of Warwicks in the UK. The university's vehicle, called WorldFirst F3 project, has a steering wheel made of curran, a material derived from carrots, that is expected to replace glass fiber and carbon fiber. It also has a racing seat made of SoyFoam, a soybean oil-based, flexible foam material. Wing mirrors incorporate materials derived from potato starch, a bib made from flax fiber, and lubricants based on plant oils."
