Why a bipartisan embrace of crypto might never touch Bitcoin

Posted by in categories: bitcoin, cryptocurrencies, energy

Crypto’s biggest skeptics see plenty of reasons to criticize the industry, but generally at the heart of most complaints is a belief that crypto is contributing very little to society while burning massive amounts of energy.

While crypto’s believers could squabble over the former point until they’re blue in the face, the latter is a little harder to deny. Bitcoin uses an estimated 204.50 terawatt-hours (TWh) of electricity per year at current rates according to the oft-cited tracker built by Digiconomist, this number is equal to the power consumption of Thailand. Meanwhile Ethereum’s energy footprint is half the size but still comparable to the power consumption of Kazakhstan. In 2018 the United States reported its total consumption of electricity as 4,222.5 TWh.

For some legislators, those numbers are hard to swallow. This week, the New York State Assembly passed a bill that had team crypto up in arms. The bill blocks the formation of crypto mining firms in the state that rely on non-renewable power. It notably doesn’t apply to existing facilities. A corresponding bill is currently making its way through the Democrat-controlled state senate. everyone, and welcome back to Chain Reaction.

A Problem That Could Plague Rapid Transport Like Bullet Trains & Hyperloop

Posted by in categories: energy, mapping, transportation

If you look at Amtrak’s route map, you’ll notice that the service isn’t really geared toward serving rural areas and smaller cities. Sure, they do stop at some smaller cities along existing rail routes, but those aren’t the point as much as a place to get fuel and let people get onto connecting services. On top of that issue, Amtrak largely uses the same tracks as freight trains, and the freight lines have been placed according to freight needs and not the needs of potential passengers. In one particularly weird case, it completely skips the Phoenix metro area, with the nearest station in Maricopa.

But I’m getting off topic a bit with that last one. The main point to gather from the map is that it’s designed mostly to connect larger cities with other large cities. Going from New York to Los Angeles isn’t a big deal. Going from El Paso to Albuquerque, well, even Amtrak tells you on the map that you’re getting on a Greyhound. Public transit really isn’t a priority in the United States, though. So maybe this isn’t a fair comparison. Let’s look at some maps in other countries for a minute:
