Volvo will use blockchain to prove its cobalt wasn’t mined by children
The dark side of electric vehicle production is that the lithium ion batteries most EVs run on require raw materials like cobalt, and cobalt mines have become notorious for using child labor. Now that Volvo has revealed its first fully-electric car, the XC40 Recharge, the automaker wants to ensure sure that the raw materials in its lithium ion batteries are sourced responsibly. For that, it's turning to blockchain.
Nokia establishes stance on conflict minerals in formal policy
Recent weeks have seen a swell of interest in corporate responsibility, particularly with regard to technology manufacturing and supply chains. Last month, Apple CEO Tim Cook affirmed his company's commitment to ethically and environmentally sound practices, evoking sentiments that were echoed today in a similar announcement from Nokia. Seizing the opportunity to establish some goodwill among socially conscious consumers, the Finnish manufacturer has just released a policy outlining its philosophy on conflict minerals -- metals like gold, tungsten and tin that have played a direct role in fueling civil violence and unrest in the Democratic Republic of Congo. In the document (linked below), Nokia acknowledged that it doesn't play a direct role in obtaining these materials, but emphasized its strict traceability requirements. All suppliers, Nokia says, must provide detailed information on the sourcing of its metals, going back to the smelter phase, at a minimum, and even to the mine itself, if necessary. The company also highlighted its adherence to guidelines established by the EICC-GeSI Extractives Work Group, which both Apple and Intel have already joined. Granted, it's impossible for a single company to wipe out civil strife and human rights abuses in one fell swoop, but with this codified approach, Nokia hopes to at least "increase transparency, ensure responsible procurement by our suppliers and sub-suppliers, and drive positive change."
NutriSmart prototype embeds RFID tags directly within food, traces your lunch from start to finish (video)
RFID tags are already used to trace everything from poker chips to hotel towels, but what if these little pellets were embedded directly within your lunch, providing everything you'd ever wanna know about that ham sandwich you're about to beast? That's the idea behind NutriSmart -- a food tracking system that revolves around edible RFID tags. Developed by Hannes Harms, a design engineering student at the Royal College of Art in London, these little markers would allow consumers to trace the entire supply chain behind every item in their cupboard, while feeding valuable nutritional information to dieters or people with particularly dangerous food allergies. Kodak, as you may recall, came up with a similar idea a few years ago, though Harms' prototype extends beyond the realm of medical monitoring. Properly equipped refrigerators, for example, would be able to alert users whenever their stock's about to expire, simply by scanning the tags. The NutriSmart concept also calls for a smart plate, which Harms describes as an "invisible diet management system." Just put your meal on the plate and an embedded reader will analyze your grub, tell you how many miles it traveled before arriving at your kitchen and transmit all of its history and caloric data to your phone, via Bluetooth. No word yet on what would happen to these tags post-digestion, though our inner 13-year-olds are giggling at the possibilities. Video after the break.
