Building a Concrete Tent

YouTube
YouTube

From the Please Send Me a Test Unit Department, here's a concrete tent. The concept is simple: cloth containing concrete it is used to create buildings (or, frankly, anything else you want to make out of thin concrete). You just put up the cloth, get it wet, then wait. The result is a durable structure without the need for pouring concrete. To form the structure, just inflate a bag under it -- though I can see how using a plywood or other substrate could also be handy, if you don't like bag-shaped buildings. I just want to know how much this costs. (Seriously. I've got uses for this stuff. I kinda need to make a Hobbit Hole in my back yard.)

First up, a video from National Geographic showing the deployment of a concrete tent:

And here's a video featuring the materials inventors explaining it themselves. Note they mention deploying it underwater. Innnteresting.

So, who's with me? Bag End replica? Let's do this.

5 Scrapped Designs for the World's Most Famous Buildings

When an architect gets commissioned to build a skyscraper or a memorial, they’re usually not the only applicant for the job. Other teams of designers submit their own ideas for how it should look, too, but these are eventually passed over in favor of the final design. This is the case for some of the world’s most recognizable landmarks—in an alternate world, the Arc de Triomphe might have been a three-story-tall elephant statue, and the Lincoln Memorial a step pyramid.

GoCompare, a comparison site for financial services, dug into these could-have-been designs for Alternate Architecture, an illustrated collection of scrapped designs for some of the most famous structures in the world, from Chicago's Tribune Tower to the Sydney Opera House.

For Sale: The Safest House in America, Complete With Hidden Command Center

For some people, locking the front door just isn't enough to feel fully safe at home. Maybe they set up a home security system. Maybe they go out and buy a fancy smart home hub with a security camera. Or maybe they spend six years and $30 million to build a veritable fortress mansion, as one guy in Atlanta did. That house, called the Rice House and referred to as one of the safest homes in America, is now up for sale for $14.7 million.

Built by an entrepreneur who hired a security architect with a background designing Justice Department buildings (and his own bunker/house), the Rice House is billed as a "modern fortress" in the real estate listing.

For its owner, creating an impenetrable home was more of a personal challenge than a real security need, according to Bloomberg. But by its features, you'd think it was built for a Bond super-villain or a head of state, not a businessman in a wealthy Atlanta neighborhood.

It has its own water and power supply, a 5000-square-foot command center hidden behind a waterfall, a vault, and doors capable of withstanding machine gun fire. There’s an indoor gun range, in case you need some target practice. There’s enough room in the garage for 30 cars, in case you have a few dozen Batmobiles—or you want to invite friends to hunker down with you during the apocalypse.

And since anyone who lives there might be more invested in staying safely inside the gates than going out on the weekends, the place has plenty of amenities that make it a standalone mini-community. It’s got its own art gallery, a gym, a bowling alley, a wine cellar, a home theater, and a pool. It has three kitchens and two commercial elevators, with staff quarters so the servants you inevitably need to cater to you never need to leave, either.

But wait, there’s more. If the house lacks something you want, that’s fine! Because according to the listing, “the property purposefully awaits final personalization.” In other words, for your $14.7 million, it’s not finished.
