Designers Built a ‘Biological House’ From Upcycled Grass, Straw, and Seaweed

The Danish architectural firm Een Til Een has revealed the latest step forward in sustainable housing: the world’s first “Biological House.”

The home was built using materials made from agricultural waste, including grass, straw, and seaweed, and was conceptualized in collaboration with the Danish Environmental Protection Agency. Not only is the reuse of this material healthier for the environment, it also prevents the harmful effects of burning the waste, which is what normally happens to this type of agricultural residue if there is no use for it, according to Curbed

“It sounds like science fiction that you can build a house from things such as tomato stems, straw and seaweed, which is just as durable as normal buildings and at the time has a healthy economy and complies with the rules,” Danish Environmental Minister Kirsten Brosbøl said. “However, the Biological House shows that it is possible here and now. I appreciate that way we really get some value from materials that otherwise would end up at an incineration plant.”

In addition to the agricultural waste being used for most of the raw building material—including tomato stems and woodchips being turned into composite boards—eco-friendly Kebony wood was used for the home’s outer cladding. According to Kebony, 40 partners were used in the construction of the home, each with an eye toward sustainability and environmental responsibility.

"Being part of this strategic partnership has been a real privilege,” Mona Gøtske, Country Manager Kebony Denmark, said. “[And] we are thrilled to have provided a façade solution for the world’s first Biological House that demonstrates the strength and sustainable values of Kebony in the best possible way.”

The modular home was built on screw piles, which allows it to be moved without tearing up soil the way a traditional concrete foundation would, as Inhabitat reported. Before it was unveiled, Een Til Een constructed this “Biological House” in secrecy in Middelfart, Denmark. But now that the project has been successfully completed, World Architecture News reports that the doors are open for visitors from all around the world to walk in and look upon the house that tomato stems built.

Why Do We Have Daylight Saving Time?

As you drag your time-confused body out of bed at what seems like a shockingly late hour next week, you might find yourself wondering why on Earth we even have Daylight Saving Time.

Though Benjamin Franklin was mostly joking when he suggested it as a money-saving tactic in a satirical essay from 1784, others who later proposed the idea were totally serious. In 1895, entomologist George Vernon Hudson pitched it to the Royal Society in New Zealand as a way to prolong daylight for bug-hunting purposes, and William Willett spent the early 1900s lobbying British Parliament to adopt an 80-minute time jump in April; neither man was successful.

During World War I, however, the need to conserve energy—which, at the time, chiefly came from coal—increased, and Germany was the first to give Daylight Saving Time the green light in 1916. Britain and other European countries quickly followed suit, and the U.S. entered the game in 1918. The practice was dropped almost everywhere after the war, but it was widely resurrected just a few decades later during World War II.

After that war ended, the U.S. abandoned DST yet again—sort of. Without any official legislation, the country devolved into a jumble of conflicting practices. According to History.com, Iowa had 23 different pairs of start and end dates for DST in 1965, while other areas of the country didn’t observe DST at all.

In 1966, Congress put an end to the chaos by passing the Uniform Time Act, which specified that DST would begin at 2:00 a.m. on the last Sunday in April, and end at the same time on the last Sunday in October. (The Energy Policy Act of 2005 extended DST by shifting these dates to the second Sunday in March and the first Sunday in November.) It didn’t require that all states and territories actually observe DST, and some of them didn’t—Arizona and Hawaii still don’t.

Throughout its long, lurching history, the supposed merits of Daylight Saving Time have always been about cutting down on electricity usage and conserving energy in general. But, as Live Science reports, experts disagree on whether this actually works. Some studies suggest that while the extra daylight hour might decrease lighting-related electricity use, it also means people could be keeping their air conditioners running for long enough that it increases the overall usage of electricity.

If your extended night’s sleep seems to have left you with a little extra time on your hands, see how DST affects your part of the country here.
