13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence

13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence
While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science. After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent – it’s a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design. Photo by Cristian Bortes Aidan Dwyer took a hike through the trees last winter and took notice of patterns in the mangle of branches. To see why they branch this way he built a small solar array using the Fibonacci formula, stepping cells at specific intervals and heights. His results did turn out to be incorrect though.

Parametric Wood Le biomimétisme ou l'art de l’innovation durable Cette approche a été définie en 1997 par la biologiste américaine Janine M. Benyus dans son ouvrage Biomimicry, sous-titré Innovation Inspired by Nature. Ce livre pionnier, rapidement popularisé aux Etats-Unis, n’a été traduit en France qu’en 2011, sous le titre Biomimétisme, quand la nature inspire des innovations durables. Les conditions du vivant Gauthier Chapelle est l’un des principaux fondateurs de Biomimicry Europa. Pour anticiper cette élimination, les tenants du biomimétisme ne se réfèrent qu’à un seul expert : la nature elle-même, la seule entité terrestre capable de maîtriser sa propre durabilité. Comment se définit le biomimétisme ? En s’inscrivant ainsi dans la durée, le biomimétisme repose sur nouvelle estimation de la valeur nature, ou plus précisément il renoue avec une estimation préindustrielle de la nature. Une vision préindustrielle ? Aujourd’hui, il est vrai que la nature demeure une source d’inspiration inépuisable chez les avionneurs.

Carbon sequestration by soils: Our best shot at cooling the planet might be right under our feet | Global Development Professionals Network It’s getting hot out there. Every one of the past 14 months has broken the global temperature record. Ice cover in the Arctic sea just hit a new low, at 525,000 square miles less than normal. If we want to stay below the upper ceiling of 2 degrees, though, we still have a shot. How to make up the difference is one of the biggest questions of the 21st century. This leaves us in a bit of a bind. Soil is the second biggest reservoir of carbon on the planet, next to the oceans. As our soils degrade, they are losing their ability to hold carbon, releasing enormous plumes of CO2 [pdf] into the atmosphere. There is, however, a solution. The science on this is quite exciting. Yet despite having the evidence on their side, proponents of regenerative farming – like the international farmers’ association La Via Campesina – are fighting an uphill battle. Scientists are calling their bluff. The battle here is not just between two different methods. Ultimately, this is about more than just soil.

Symmetry in Plants: Phyllotaxis 1. Observing Spiral Patterns > 2. Spiral Applet > 3. Dynamical Model Applet > 4. Cylindrical Spirals > 5. Cylindrical Spirals Applet > 6. 4. In the three previous sections, you explored spiral structures that are observed when looking at a flower from above, or a pine cone from below. In this section, we go over steps similar to Section 1, but instead of planar spiral, we observe and create planar ones. Task 20: Using plants that you have available (eg. cylindrical pine cones, cacti, pineapples, palm trees, flowers stems from which you may want to cleanly cut the leaves), observe and count spirals winding up in opposite direction up the cylindrical surface. Task 21: Using the loose cylinder circles sheet, find a way to place one dot on each line in such a way that, as you close up the sheet into a cylinder, the dots form a regular spiral. Task 22: What kind of rule similar to that of the Remark in Task 2 are you applying to make your construction? Congratulations! 1.

Eoliennes : l'innovation par le design allez, encore une couche ITER, comme airbus, Eurotunnel et les frégates de « l’île de taille vent « , c’est la pratique façon qu’utilisent nos dirigeants pour produire des factures à rallonges. Celles-çi peuvent être largement multipliées en fonction de la gourmandise de ceux qui les parasitent. Ainsi, il devient difficile de vérifier comment des milliards d’euros sont détournés au profit de despotes ou de corrompus. Dans le cas d’ITER, 20 milliards d’euros sur 20 ans pour fabriquer une grosse cocote minute et la raccorder au réseau EDF...ça fait mille millions d’euros par an, avec trois cent emplois ouvriers, (et x mille chercheurs !) Pour moins que cela, on pourrait doubler chaque poteau électrique, ( Il y en a encore 65000 non enterrés dans le département de la Creuse, 254.OOO moyenne tension, et donc plus ou moins sept millions dans le pays. ), d’un semblable, mais éolien.

Heating up the Games: Why the British Isles could be the only viable Olympic hosts Only four Northern hemisphere cities are likely to be cool enough to host the summer Olympic and Paralympic Games by 2100 – Belfast, Dublin, Edinburgh and Glasgow Tropical Rio de Janeiro is in the middle of an Olympic-Paralympic Games festival of sport, with Tokyo primed to take over in 2020, and Paris, Los Angeles, and Budapest jostling over who gets to host the Games four years after that (Rome is also technically in the running but nobody expects its bid to survive much longer if the new mayor sticks to her election promises). But a warming climate suggests that sites for future Olympics will be significantly more restricted. Summary of all 645 northern hemisphere cities in 2085 capable of mounting the Summer Olympics.

Parametric Explorations for an Outdoor Sculpture An innovative outdoor sculpture at Washington University School of Architecture: This is a class project with mixed media (plywood and plastic), under the direction of Joe MacDonald of Urban A&O. It is an organic shape of concave shapes that play with light and shadows. Designed, fabricated and assembled by Zephyr Anthony, Andrew Davis, Kyle Fant, Xiaoshuang Hu, Allyson Justmann, Andrew McCready, Kelly Peoples, Xiaofei Ren, Bo Sheng, Jordan Smith, Benjamin Stephenson, Duo Yu, Thomas Watkins. This research and design studio focused on parametric explorations or reticulation: division, marking, and assembly with the intention of forming programmatic and structural networks. They were seeking creative architectural solutions based on material properties, formal geometry and the spatial implications of a full scale installation. Students worked as a team when they approached the fabrication component of the studio. -> EVOLO SKYSCRAPERS 2 - Limited Edition Book

Le Pelamis : Des articulations pour capter l’énergie des vagues Un nouvel équipement flottant de récupération de l’énergie des vagues, conçu à Edimbourg, est destiné à aider l’Ecosse à atteindre ses objectifs ambitieux quant au développement d’une "énergie verte". Principe de fonctionnement du Pelamis Le mouvement des vagues agit dans chaque articulation de la structure. Ce mouvement est utilisé pour produire de l’électricité crédit : Ocean Power Delivery Limited Structure semi-émergée, composée de quatre cylindres reliés par des articulations, ce serpent métallique est positionné dans la direction de propagation de la vague. L’énergie produite est envoyée, par l’intermédiaire d’un cordon ombilical, dans les fonds marins et ensuite acheminée à terre. Avantages : Pas de fondation donc peu de frais d’installation, le pelamis est remorqué et amaré en mer Sa mobilité permet une maintenance aisé (remorquage à terre) Inconvénients : Réalisations industrielles et projet autour du Pelamis Inauguration des premiers Pelamis commerciaux au Portugal

Green-powered boat prepares for round-the-world voyage | Environment Dubbed the “Solar Impulse of the seas”, the first boat to be powered solely by renewable energies and hydrogen hopes to make its own historic trip around the world. A water-borne answer to the Solar Impulse – the plane that completed its round-the-globe trip using only solar energy in July – the Energy Observer will be powered by the sun, the wind and self-generated hydrogen when it sets sail in February as scheduled. The multi-hulled catamaran is in a shipyard at Saint Malo on France’s west coast, awaiting the installation of solar panels, wind turbines and electrolysis equipment, which breaks down water to produce its component elements, hydrogen and oxygen. “We are going to be the first boat with an autonomous means of producing hydrogen,” says Frenchman Victorien Erussard, who is behind the project – confidential until now – with compatriot Jacques Delafosse, a documentary filmmaker and professional scuba diver. The vessel itself has a storied past.
