Windcatcher the Huge Wooden Wind Generator

Windcatcher the Huge Wooden Wind Generator

Engineers have designed a new type of gigantic wooden wind generator dubbed the “Windcatcher” that could rise higher than the Eiffel Tower to tap into more powerful winds and generate huge amounts of renewable electricity far offshore.

At 1,066 feet (325 meters) from anchoring base to propeller tip, the proposed Windcatcher wooden wind generator system would surpass the iconic Parisian landmark’s height of 1,063 feet when fully built. But rather than offering tours of city views, this would allow the colossal tower to leverage faster wind speeds at higher altitudes than conventional wind turbines mounted closer to shore. Architects envision groups of these wooden wind generator megastructures with spinning wind turbines dotted along their central shafts, powering entire regions with clean energy.

Winds Tend to Blow Stronger Higher Up

Wind flow is enhanced the higher you go because ground obstacles like hills and buildings cause slowing friction. By elevating up into less disrupted airflow, the Windcatcher’s turbines could rotate 50% faster than ones constructed only 300 feet up. More spin velocity means manyfold more power generation. Modeling shows electricity output from a single Windcatcher could equal several traditional wind towers running in parallel. This boosted productivity per tower could make building fewer giants more efficient than patching seascape views with ever more waves of smaller mills.

Engineering a Gigantic Wooden Wind Generator

However, efficiently scaling turbines to Eiffel defining heights poses profound infrastructure challenges around stability, longevity, and safe maintenance access throughout the multiyear operation. The proposed Windcatcher design incorporates a sturdy yet flexible solid timber tower base tapering into an open skeletal wood frame swirling up to its peak generation capacity. The entire structure can gently sway to dampen extreme gust loads without catastrophic failure risk. Metal vibration dampeners also help absorb wind energy to limit motion.

Ringing the tower’s exterior, helical rampways, and grated platforms circle up to turbine machinery requiring routine inspection or emergency repairs. Cargo lifts and even tilting gondolas mean specialized crews can access any point from base to pinnacle in most conditions while remaining secure. But whatsoever precautions, embarking 1,000 feet into the North Sea gusts to bolt down wayward equipment is no task for the faint of heart.

The wooden wind generator concept has grabbed attention across renewable energy circles, yet experts debate feasibility obstacles around truly enormous timber joinery, massive construction logistics, operating equipment endurance, and connection infrastructure. Building numerous near Eiffel-topping wooden wind generators certainly nudges current offshore wind realism boundaries. However, proponents argue that visionary, clean power goals require expansive thinking, including wooden wind generators. However, intimidating initial steps appear. Our energy appetites will only expand, and every field bears longshot innovations that will later prove pivotal.

The proposal’s futuristic allure is clear. Windcatcher wooden wind generators evoke images of natural organisms gently swaying amid the waves, smoothly converting the wind’s energy into electricity, helping human life flourish onshore. Their sheer epic scale captivates the imagination much akin to Parisian Gustave Eiffel’s original wrought iron icon that long-held records as the world’s tallest manmade structure. Perhaps someday, rows of these block-long towers may claim their own position as ultimate wind energy titans built to sustainably power nations using renewable materials and ingenuity.

TreeTote: The Tote Bag That Saves +1100 Liters of Water

TreeTote: The Tote Bag That Saves +1100 Liters of Water

Did you know that a cotton tote bag consumes +1141 liters of water to be produced?

Cotton tote bags have flooded the market. Originally manufactured to combat single-use bags, this bag has become a trendy accessory. Brands have turned it into a true cult accessory. Yet, cotton tote bags are an ecological disaster. Cotton production involves astronomical amounts of water and pesticides, leading to soil drought and the development of dead marine zones.

In recent years, the “ fiber gap” phenomenon has appeared. Demand for cotton continues to rise while supply decreases. The consequence is skyrocketing prices. Natural fibers like cotton are increasingly being replaced by fibers derived from fossil resources. Cotton is predominantly produced in Asia and requires intercontinental transportation. Off-centre cotton supply chains release large amounts of CO2.

Organic growing systems are better for the soil as they maintain a higher soil quality, which reduces the runoff into local rivers. The soil is also much more resilient and can withstand extreme weather. Healthy soil acts like a sponge – it can absorb and retain water for longer periods, including droughts. This leads to a much lower consumption of organic cotton though it remains 90% higher than our lyocell wood fibre.

The Tree Tote

The TreeTote, a 100% wood fiber tote bag, was developed to address these challenges. Our totes are made from 100% European production. We keep our supply chain as close as possible to reduce CO2 emissions related to transport while producing a socially responsible and affordable bag. Our supply chain is exclusively European and includes three streams: Made in Europe, Made in the Alps and Guaranteed French Origin. The entire supply chain is traceable via the Respect Code on all our bags. By scanning the QR codes on our bags, you will see the entire journey from research to development, raw materials, production, distribution and use.

The prime material for our bags is timber, and they are made from 100% wood fibre from sustainable sources. Of the tree species used in the sourcing of wood for the TreeTote, the main contender is Beech. Beechwood availability is increasing as forests are being returned to a more natural species mix. Rising temperatures are also increasing its growth rate. This beech wood comes purely from PEFC/FSC-certified sources.

The material is generated by thinning or damaged wood left over from other operations. Almost all of the wood used to produce the TreeTote comes from Austria, where the fibre is produced. The rest comes from neighbouring countries, minimising transport and therefore the carbon emissions that come with it. Transport is highly optimised to keep our carbon footprint to a minimum. Shared transport is used whenever possible and, for longer distances, low-emission transport such as trains is prioritised.

Over 99% of the solvent used is recovered and recycled, and water consumption is reduced drastically. Even sustainable bags use plastic thread and tags, which are cheaper and widely available. We stray from plastic and only use TENCEL accessories to make our TreeTote 100% wood fiber. We also don’t add any extra mechanical or chemical steps to the line after weaving, which is rare in textile production, to save energy and water.

Regarding the water used to produce our tote bag, we achieved a 90% reduction in water consumption. If we compare our tote bag to a conventional cotton bag, which uses about 1200L of water, we reduce consumption by 99%. In the case of organically grown cotton, the reduction reaches 90%. Over 39,158,595 liters of water have been saved by TreeTote so far as a replacement for cotton bags.

Because dyeing, and the processes that come with it, have an enormous impact, especially due to water use for the dying itself and the washing steps that follow. We, therefore, choose to work with the fabric in its natural white colour.

OEKO-TEX® STANDARD 100 is one of the world’s best-known labels for textiles tested for harmful substances. It stands for customer confidence and high product safety. TreeTote has been awarded Class I certification, complying with the label’s strictest requirements.

After using the tote bag as many times as possible, we recommend recycling it with textiles as this is the highest value disposal. The Tree Tote is also 100% compostable.

Sustainable Housing that can be Recycled

Sustainable Housing that can be Recycled

Building a house from the ground up can be environmentally damaging. Buildings have a significant carbon footprint, with over 41% of global energy consumption attributed to buildings and structures. Buildings and materials also produce dangerous emissions that pollute our air, and the construction industry alone generates more than 170 tons of debris annually. There is also the issue of landfill waste, excessive use of water and noise pollution caused by the construction of buildings and houses.

SPEE Architecten, an architecture firm in the Netherlands, may have found a sustainable solution for building houses. Their projects focus on innovation and sustainability and creating healthy elements for both the residents and the environment. The architects created their newest project Speehuis House to create a site that minimally impacts the surrounding trees and wetlands with a structure that could be dismantled and recycled.

The house was built in a wooded area adjacent to a wetland area. The house’s form, size and layout are tailored to the needs of a family with three and adjoins SPEE Architects’ office premises. Large, strategically-placed windows offer a lot of natural light to the inner spaces and views of the outdoors. The entire house is made of circular and biobased materials. For example, the exterior walls and sloping roofs are made from untreated, high-density, biobased bamboo slats.

The team used Bamboo X-treme beams which consist of more than 90% of thermally modified bamboo strips. Bamboo absorbs a lot of CO2 during its growth, which remains stored throughout the product’s lifespan. Bamboo X-treme is extremely durable, dimensionally stable, and harder than most types of wood. When the bamboo fibers and resin are compressed at high temperatures, the natural sugar in the bamboo caramelizes, rendering it rot-resistant. These materials can be conveniently dismantled, adapted and recycled as need be.

Most of the home’s shell, including the stairs, interior doors, desks and cabinets, is made from cross-laminated timber that was chosen to avoid using concrete. The entire shell was prefabricated in less than a week. The wood was sourced from responsibly managed forests and was selected to create a natural and healthy indoor environment and a carbon sink. The architecture team estimates that over 93 000 kg of CO2 is stored within the building. In comparison, the same building built in concrete would produce 46,694 kg of CO2.

The home that SPEE Architecten has built shows us a future of what the construction industry can look like and how we can live more sustainably. The design is spacious and tasteful and allows for comfortable living without causing harm to the environment. If more architecture firms transitioned to building homes like the Speehuis House, the environmental impact from the construction industry would decrease substantially.
