Comments Off on Doctors warn cities that LED street lights can cause serious health issues

Many cities have shifted to LED lights in a bid to be more energy and cost efficient, but LED lights have another price, and it comes at our health. This week, the American Medical Association (AMA) issued an official statement, in which they warn that cities need to consider resident’s health when installing the bright lighting because it can cause damage to our sight and disrupt our circadian rhythms. Think of it as living with a bunch of giant computer screens blaring around your neighborhood, and you get the idea. The AMA unanimously adopted an official policy  giving cities guidelines for installing lighting that takes human health into account. These guidelines include keeping lighting at a temperature of 3000 Kelvin – within the warmer spectrum of light that humans are accustomed to. The guidelines also call for dimmer lighting that isn’t so harsh on our vision. Related: A Simple Change in Lighting Could Be the Secret to Beating the Monday Blues It’s easy to forget about how much of an impact lighting has on our health because it is so ubiquitous. But bright LED lighting, particularly bright lighting in the cooler temperature spectrum, can actually damage our retinas and contribute to glare that can cause temporary, or even permanent vision loss. Blue-spectrum lights and lights above the 3000k recommendation can also impact our sleep by disrupting human circadian rhythms . Essentially, your body thinks it is morning even though you are trying to get some sleep, which can lead to all kinds of problems, from fatigue to even an increased risk for breast cancer. These bright lights can impact wildlife as well, disrupting bird migration, feeding and sleep behaviors. And let’s not forget that the dark sky is vanishing at an alarming rate. The AMA calls for efficient lighting that minimizes the blue spectrum and that is shielded to protect against glare. It also calls for dimming during non-peak periods, like the early morning.

Comments Off on Enchanting tiny home combines French rustic charms and modern luxuries

French rustic charms and modern luxuries come together in this beautiful tiny home on wheels. France’s tiny house company Baluchon has outdone themselves again in their latest build called the Ostara, a tiny home built on a six-meter trailer. Currently located near a horse farm in Toulouse, the light-filled timber abode looks surprisingly spacious despite its small size and sleeps two in a loft bedroom. Custom built for clients Nathalie and Sebastien, Ostara was named after the stable close to the tiny home’s location. Although charming and rustic on the outside, the spruce -clad Ostara makes a grand impression with its large French doors flanked with curtains that open up to a light-filled living room. A large 1.8-meter-long sofa forms the living room’s focal point and can also comfortably lodge an overnight guest. A small bookcase, wood-burning stove , and a small dining table that accommodates three people is located to the left. To the right of the living room is the kitchen with a full-size sink, pantry, two-burner stovetop, fridge/freezer, and a gorgeous extendable wooden countertop. The bathroom with a full-size shower and composting toilet are tucked into the end of the home. Related: Fully-furnished tiny house from France easily fits a family of three A corner staircase with built-in storage leads up to the mezzanine with a large loft bed . Multiple double-glazed openings, including a broad bay window and one-meter-wide circular window, punctuate the home and provide views of the horses and rural surroundings. Sheep wool, cotton, linen, hemp, and wood fibers were used for insulation. The home is made from locally sourced materials. Baluchon’s beautiful homes are only delivered in France due to the company’s desire to limit carbon emissions. + Baluchon Via Tiny House Talk

The project uses 3d-printed piezoelectric cells applied to each trolley pole, trolley bus elevation, tire and overhead wire. Aluminum consolidated carbon nanotubes , which increase the heat and electrical conductivity of the material embedded within the structure, are combined with the steel frame, concrete-clad helix. The aluminum frames are printed with piezoelectric crystals that generate electricity from the air flow and pressure exerted from the trolleybus and its overhead wire movement. Related: Margot Krasojevic’s solar-powered sand turbine hotel aims to stop the spread of the Gobi Desert Elevated walls further increase the vibration of the trolley-poles, augmented by wind and rain. These vibrations amplify the the piezoelectric cell displacements which, in turn, generate energy. The design will act as an electrical amplifier, and will provide street lighting and WiFi access to immediate neighborhoods. Users will also be able to use the system to power their gadgets and smart cars , while the electric current stimulates root growth in plants. + Margot Krasojevic

Comments Off on Theresa Harmanen’s ALMA Lamp Is Powered by Trees

Theresa Harmanen ‘s Alma Tree Lamp is an innovative lighting design concept that takes energy directly from nature without destroying it. Designed to be plugged directly into a tree, this project explores the energy created when a tree “communicates” with its soil. By harvesting and storing this energy, Alma forgoes the need for a grid power source, lighting up the streets while highlighting the beauty of plant life.

Image via Yanko Design This seems like a slightly more Alice In Wonderland, slightly less majestic version of Ross Lovegrove’s solar tree-like streetlights , but designer Omar Ivan Huerta Cardoso is giving fake-tree-solar-streetlighting a go with the Light Tree. This one, however, has a few real sprouts incorporated into the design, which is nice – but can that overcome some of the other problematic design flaws?… Read the full story on TreeHugger
