What if we grew our fruits to be shaped as containers?

gourd_cups_1

I remember one snarky image that made its rounds around the internet. It featured peeled oranges stored in plastic containers, with a caption that read “If only nature could find a way to cover these oranges so we didn’t need to waste so much plastic on them”. It seemed like a glorious act of stupidity, that someone at the supermarket would peel fruits, discarding their natural packaging, and then store them in man-made plastic boxes… so Brooklyn-based design studio Crème did the exact opposite.

Crème chose to reverse the process, forming fruits into containers, rather than the opposite (storing fruits in them). Using the easy-to-grow and tough-when-dry gourd, Crème created specialized 3D-printed molds that allowed the gourd to grow in certain shapes. Gourds are fast-growing plants that bear robust fruit each season. Once dried, the gourds’ strong outer skin and fibrous inner flesh becomes watertight, explaining why they’ve been used for centuries as water-storage and drinking vessels.

Crème has devised a method of mass-growing these gourds, forming them into glasses and carafes, using 3D printed molds that limit the growth of the gourd and give it shape (the Japanese do the same with watermelon, making them cubical and therefore easy to pack). Once the gourd dries out, the mold is opened, the fruit is cut, and its insides cleaned. You’re left with the HyO-Cup… a product that’s watertight, and formed with a surprising amount of accuracy. If the molds are designed well, you can achieve any shape, making stylized containers, or even more functional, stackable designs. Once done, instead of going into a landfill, the HyO-Cups go into a composting pit!

Recyclable organic solar cells: a clean fuel future made possible by trees

Solar cells are made from trees

You don't have to know Shel Silverstein to know that trees are exceptionally giving. They're responsible for our homes, paper, air, furniture and, now, energy -- the "clean" kind, that is. Researchers from the Georgia Institute of Technology and Purdue University have jointly devised a patent-pending method to build organic solar cells using plant-derived substrates. Known as cellulose nanocrystal substrates (or CNC), these solar cells benefit from being truly disposable, eliminating the waste that results from the use of alternative materials like petroleum or glass. The CNC-made cells are not only transparent enough to allow light to pass into an embedded semiconductor, but they also dissolve when submerged into water, thus earning the esteemed recyclable distinction.

Although this is undoubtedly a breakthrough for clean energy tech, it's by no means a near-future reality. Apparently, current cells can only yield a 2.7-percent conversion efficiency rate, which falls far below the 10-percent threshold met by rival fabrication methods (i.e., petroleum and glass). So, there's still significant work to be done before the team can improve production and achieve parity with those less "recyclable" options. Until that time, consider this a comforting reassurance that a clean fuel era is well within reach.

Insert Coin: Berlin Boombox recyclable cardboard stereo (video)

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

It's been years since we've spotted a proper handle-sporting boombox on this side of the equator (in public, at least), but we're decidedly impressed with this unique Kickstarter creation, dubbed the Berlin Boombox. Constructed nearly entirely of cardboard, save for some metal- and plastic-based essentials, the speaker rig ships disassembled in a flat cardboard box. Getting the Boombox up and running shouldn't require much effort, however -- the designer states that you won't need any tools during the quick assembly process. After you're done, you can connect the setup to any source with a 3.5mm headphone jack, then control volume with the large aluminum power/volume knob. The Berlin Boombox also ships with four AA batteries, though it's not clear how many hours of music you'll be able to pipe through the speakers with that initial set of cells. We also can't speak to sound quality, though there is a free custom sound profile available for iOS devices -- audio "will be remastered in real-time to use the full potential of the Berlin Boombox."

You can pre-order your own with a $50 pledge, saving you 9 bucks off the estimated retail price. There's also a "limited edition" two-tone box, available with a $100 pledge, while $250 will net you a custom-designed model, which can also be paired with a dinner and tour of Berlin with the inventor if you're willing to fork over $500 or more. There's just shy of two weeks left during the funding period -- you'll need to provide that financial support before noon on April 25th. The project is on track to meet its $14,000 funding goal, however, so it's fairly safe to say that you'll be able to snag one of these cardboard contraptions even if you aren't ready to take the plunge just yet. Jump past the break to see the Berlin Boombox in action, and to catch up with our last Insert Coin project: The PowerPot.
