oh shit that goes so hard

looks better than the actual hatsune miku

no it’s a cosplay from the Neon Genesis Evangelion series. the boy’s shinji and the red one is … what’s her name? katsuragi? anyways she’s supposed to watch over him and is probably giving him a stern lecture rn.

yeah huh what

i remember reading an article about this but i can’t find it anymore

nvm you’re right

yeah i think the same thing. energy sources are critical infrastructure, like streets and housing. imagine if you had to drive 1000 km just to go from your house to your workplace. unimaginable

Hydrogen is difficult to work with, massive compression or cryogenic temperatures. Metal embrittlement is a long term concern.

that’s hearsay. there’s lots of studies about hydrogen pipeline / storage feasibility, such as the ones i’ve linked above. pls stop spreading misinformation.

electrolysis alone has 80% electric -> hydrogen conversion efficiency minimum, sometimes close to 100%. most solar panels have 20% sunlight -> electric efficiency. so total sunlight -> electric -> hydrogen efficiency is about 20% * 80% = 16%. which might not sound like a lot but remember there’s a ton of sunlight so wasting some doesn’t matter.

it’s more about the economic cost to describe how feasible something is.

well, technically, the term transformer refers to any device that converts the wave-form from one form to another. so a rectangle -> triangle converter would be a transformer.

in most cases, though, it’s only used in the sense of “voltage converter”. and these exist for AC and DC

nvm

yeah, AC won during the current wars in 1900, mostly because efficient transformers were only available for AC at the time.

nowadays DC is often used for high-power long-distance transport though.
