The 1973 GMC Motorhome was—and still is—a sight on the road today. This groundbreaking RV was just as interesting as its sleek body, with a V8 powering the front wheels and a spectacularly 1970s interior. And because it was the early ’70s, we had a different notion of what was okay to spray into the atmosphere as you drive. Like sewage, which an obscure option allowed this GMC to do.

One of the options available for the GMC Motorhome was a system called Thermasan, which promised to improve on one of the worst parts of RV ownership: Black water. That’s a euphemism for the raw sewage, which accumulates in an onboard tank and has to be disposed of at dumping stations. It’s as gross as it sounds, and it’s why someone at RV accessory manufacturer Thetford Corporation thought there had to be a better way. And so, the Thermasan was born.

The premise of the Thermasan “waste destruction system” was simple: Dump black water through the hot exhaust to sanitize and dispose of it. According to a maintenance manual for the 1973 model, this was done using a wiper motor-powered pump connecting the black water tank to the exhaust, where it was plumbed in just upstream of the muffler. A screen prevented solid waste from entering and clogging the system, which would’ve been hellacious to fix. Amusingly, Thetford called the exit an “ejection orifice.” The jokes write themselves.

I've no idea how I missed Henry Segerman until now. This is the antithesis of clickbait: a simple title, "expanding racks", hides a wealth of surprising visuals and explanations. There were multiple times, watching this video, where I said "oh!" out loud. Give it at least fifteen seconds. And full marks for including some project files in the description, too!

Excerpt:

When Sinners recently received a record-breaking 16 Oscar nominations, the response was overwhelmingly celebratory, but not uncomplicated.

The nominations capped a year in which the film had already defied expectations at the box office. An original horror film with no built-in franchise, Sinners broke multiple domestic and international records and earned more than US$300 million during its theatrical run.

Critics also responded strongly, praising Ryan Coogler’s direction and the film’s blend of spectacle and social commentary. Those reviews helped cement Sinners as both a commercial hit and a critical success.

Sinners doesn’t resolve longstanding debates about Black recognition or racial equity in Hollywood. However, its nominations arrive at a moment that suggests wider audience interest — and possible film industry openness — to Black films that are culturally specific, formally ambitious and uninterested in proving their importance through suffering alone.
