So many ways to store energy, once it's in a malleable electric form.

So many ways to store energy, once it's in a malleable electric form.

From the article: "[R]ail storage is faster, with lower capital costs, than its main rival in grid-scale storage, pumped hydro (which pushes water up and downhill just like ARES pushes slabs). It's also more scalable than pumped hydro — you can do it incrementally all the way from 20 MW to 3 GW — and can be located in more places. All it needs is some open land and a slope. Notably, it doesn't need water, which allows it to operate in the arid American West."

#Security weirdness of the day: I followed a link to #Instagram, and it told me they'd noticed an unusual login. Now I hardly ever log in to Instagram, so I imagine any login would be tagged as unusual. But this login - which blocked me from viewing a public post until I answered whether it was me or not - was from two months ago. I have no idea if I logged in then. I might have, for whatever reason, but who remembers where they log in for several months? Not I. The follow-up page had me change my password, without any other kind of challenge. I got a mail afterwards, but seriously, that's some weird shit.

If only the sun flares in my photos were this impressive. Originally shared by Astronomy Picture of the Day (APoD) A Solar Filament Erupts Image Credit: NASA 's GSFC, SDO AIA Team https://apod.nasa.gov/apod/ap180916.html What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere, causing visible aurorae. Loops of plasma surrounding an active region can be seen above the erupting filament in the featured ultraviolet image. Although the Sun is now in a relatively inactive state ...
