A Tiny House EcoVillage for the Homeless

d52f0518-9094-44a3-a4c9-9ef713008aa8

The YouthBuild Program in collaboration with the Alternative Energy Program at New Market Skills Center are busy building a so called Tiny House EcoVillage, which will consist of three 70 square foot tiny mobile sleeping units, and 30 larger, permanent tiny houses. These will be placed in Quixote Village, which is part of Olympia, WA’s Camp Quixote, also known as Olympia’s Homeless Tent City.

A Home That is Heated and Cooled Organically

ext

A team of students at Waseda University in Japan have constructed a prototype for a house that can be heated by composting straw. They dubbed the dwelling the “Recipe for Life” house. Using the heat generating composting process for the purpose of heating a dwelling is not a new idea, but it is definitely one that should be explored further, and perhaps brought closer to the public. The Recipe for Life prototype house is certainly an interesting proposition in that regard.

Supercapacitors Made of Trees

process

Supercapacitors are high-power energy storage devices with far-reaching industrial applications, such as electronics, automobiles and aviation. However one of the main reasons why they have not been adopted more widely is the high cost and the difficulty of producing high-quality carbon electrodes needed to build them. But a team of scientists at Oregon State University has made a discovery that could change all that. They found a process by which cellulose heated in a furnace in the presence of ammonia can be turned into fundamental building blocks for supercapacitors. Cellulose is Earth’s most abundant organic polymer and one of the key components of trees. In other words, trees could one day be instrumental in creating high-tech energy storage devices.

The approach discovered by the scientists is capable of producing nitrogen-doped, nanoporous carbon membranes, which form the electrodes of a supercapacitor, in a cost-effective and rapid way. Furthermore, the only byproduct of this process is methane, which can be used immediately as fuel, making the method very environmentally friendly.

The carbon membranes produced with this method are extraordinarily thin at the nano-scale, meaning that one gram of them can have a surface area of nearly 2,000 square meters. This is what makes them so useful in supercapacitors. The process used to create them is basically a one step reaction, which is very fast and cheap to perform.

The scientists themselves were quite surprised at their discovery. As Xiulei (David) Ji, an assistant professor of chemistry in the OSU College of Science and a team member, put it: “For the first time we’ve proven that you can react cellulose with ammonia and create these N-doped nanoporous carbon membranes. It’s surprising that such a basic reaction was not reported before. Not only are there industrial applications, but this opens a whole new scientific area, studying reducing gas agents for carbon activation.”

Supercapacitors are needed primarily for devices where rapid power storage and short, but powerful energy release is required. These include computers and consumer electronics, but can also be used to power cranes, forklifts, and even defibrillators. They can also be used to open emergency slides on an aircraft and for improving the efficiency of hybrid electric cars. Supercapacitors are also capable of capturing energy that might otherwise be wasted, while their energy storage capabilities may also be used to assist the power flow from alternative energy systems, like, for example, wind energy.

Finding a cheap and environmentally benign way of producing these devices is, needless to say, a great breakthrough in the field.

Upcycle House Built From Used Shipping Containers

ext

The Danish architecture firm Lendager Arkitekter recently completed the experimental Upcycle House in Nyborg, Denmark. The goal with Upcycle House was seeing if carbon emissions of a home can be reduced through the use of recycled and upcycled building materials during the construction process. The end result was the reduction of CO2 emissions by 86% compared to a benchmark house. Upcycling is a sort of a next step in the recycling process, namely using recycled products and turning them into new materials or products of higher quality and greater value. In the case of Upcycle House, this reduced the need for new production and therefore reduced the CO2 emissions.

Unique Home Made From Used Car Parts

ext

Architects Karl Wanaselja and Cate Leger of Leger Wanaselja Architecture studio built for themselves a one-of-a-kind home in Berkeley, California. The McGee House, as they are calling it is constructed mainly from salvaged car parts and the repurposed waste product called poplar bark. The 2-bedroom house measures 1140 square feet and is the home of the architect couple and their teenage daughter. From the outside, the house is only 14 feet wide, which belies its actual size.

Polyhedral Tiny House Makes For a Very Unique Cabin

noa-ext

Architect Jaanus Orgusaar from Estonia has designed a tiny modular house that is also a polyhedral form. This fascinating shape occurs in nature, such as in the molecular build up of diamonds and in honeycombs, and it is quite interesting to see it applied to a house. Jaanus has called his cabin Noa, and it consists of twelve identical rhombic faces setup into a unique three-dimensional form.
