Unless I missed something big, it seems to me like the video doesn’t discredit using abandoned mine shafts and gravitational potential energy, just a particular company’s approach to this sort of energy storage, where they wanted to do it above ground and overcomplicated.
I don’t think the article’s claims of “enough energy to power the planet” carry any weight, but it is nice to see an innovative use to “dead” infrastructure, right?
Literally never looked into grav batteries, but what are the problems with the “tech” (if you can even call it that…)?
Laptops are being gradually added to the list of devices within scope of this change. It only counts for any new device being sold on the market after the changes take effect.
The clause only makes sure that chargers do not limit, when connected to competitors devices. The regulation is coming from an e-waste perspective, which the EU has made it clear that it is not interested in entertaining or letting companies push them around.
As I commented above, the regulation clearly states “any additional charging protocol allows for the full functionality of PD… irrespective of the charging device used.”
So they can’t have both unless they split EU & RoW devices.
This is not correct for devices being sold to the EU at least. Part of the amendment to the Radio Equipment Regulation outlines the exact standards for power delivery that must be used, and that interfaces which are capable of being charged @ > 15W must “ensure that any additional charging protocol allows for the full functionality of the USB Power Delivery…”.
For data transfer, I don’t see the point and future improvements to USB will come from industry in future.
The only way around this is with a wireless charging protocol, but manufacturers are moving away from that it appears.
You need an incredibly robust quality management system to even achieve certification (allowing you to place on the market) when creating systems which include life support function, or functions which potentially could kill a user. All potential changes both within and outside of the manufacturers’ control MUST be assessed and constantly monitored so such issues CANNOT arise.
No one should be able to legally place an unsafe app on the market, or legally perform changes to the app without the necessary checks and balances.
Medical device approvals in most countries are definitely not the wild west. Although they are not perfect.
