A petabit of data can be fit on an optical disk by storing information in 3D. They say that's 125,000 gigabytes on a single DVD-sized disk.
"Optical disks like DVDs and Blu-rays are cheap and durable but can't hold much data. Until now, optical disks store data in a single layer of information that's read using a laser. Well, you can kiss those puny disks goodbye thanks to a new technique that can read and write up to 100 layers of data in the space of just 54-nanometres, as described in a new paper published in the journal Nature."
How do they do that? The research paper is paywalled but the abstract says:
"We develop an optical recording medium based on a photoresist film doped with aggregation-induced emission dye, which can be optically stimulated by femtosecond laser beams. This film is highly transparent and uniform, and the aggregation-induced emission phenomenon provides the storage mechanism. It can also be inhibited by another deactivating beam, resulting in a recording spot with a super-resolution scale. This technology makes it possible to achieve exabit-level storage by stacking nanoscale disks into arrays, which is essential in big data centres with limited space."
Femtosecond lasers, eh? How much is this reader/writer going to cost? I have a feeling it won't be showing up at Micro Center any time soon. But might be good for Google, etc, to back up the massive amounts of data they have in their data centers.

Disused mine in Finland is being turned into a gravity battery to store renewable energy
The firm has developed an energy storage system that raises and lowers weights, offering what it says are “some of the best characteristics of lithium-ion batteries and pumped hydro storage”.
When there is excess power - from wind turbines on a windy day for example - weights would be winched up the Pyhäsalmi mine’s 530-metre auxiliary shaft. To generate energy, these weights can be released turning the winches into generators creating either a short burst of electricity or a slower trickle depending on what is needed.
The gravity energy system would be able to store 2MW of power and integrate into the local energy grid.

30 TB hard drives coming. Moore's Law keeps cranking. Thanks to something called "heat-assisted magnetic recording (HAMR) technology". It works by temporarily heating the disk material just in the spot that's being written, and this allows writing to smaller regions at higher densities. It's tricky to do but apparently Seagate has mastered the technique. Apparently this technology was announced last June but volume production hasn't fully kicked in yet.

In need of more space?
On many notebooks it is possible to install several storage devices.
One way is to use an mSata drive in the wwan slot, if it is not needed for a modem (or if a modem is needed, it's possible to use an external usb modem instead).
It might be also possible to use a wifi card M.2 slot for storage: With an adapter NVMe drives can be connected.
And for machines with an express card slot, there are express card to NVMe adapters available.
So it's possible to have a storage device in the wwan slot, in the wifi slot and/or in the express card slot.
There are also dual slot adapters available, which make it possible to install two M.2 NVMe storages (instead of having one SSD).
Besides these solutions there are probably even more ways to install more storage devices on (older) notebooks.
Does anyone know if there is a way to use one slot for two 2,5" SATA drives (via adapter)? Did not see such a setup yet.

My Solar Exploits
Not a lot to report. Had a multi-day overcast and snow and the batteries bottomed out and the system automatically switched to grid power and started charging the batteries. The confusing thing is that it made the switch at a different point and in a different manner than the first time. No big deal, but will need to figure out why and maybe adjust some parameters.
This bottoming out puts a small glitch in my hopes of running a full month just from Solar/Batteries but still hoping to see a significant difference in the monthly Xcel bill...should know in a couple of weeks.
Also moved my panels around in the backyard to hopefully better take advantage of the winter sun. Moved one set back against the rear fence where I can leave them at a more productive angle. We'll see.
Enjoy!
