01) Nemo’s Garden

“Our underwater farm is composed of 6 air-filled clear plastic pods, anchored to the bottom of the sea by ropes, chains and weights screws, just off the coast of Noli, Italy. These acrylic structures, resembling large balloons, float at different depths, between 15 and 36 feet below the surface of the water”

01) Boeing retiree finds meaning inventing micro homes & high speed trikes


“Inspired by a father and uncle who relied on “imagination, calculation, patience, determination and a few handy tools”, Paul Elkins has spent more than half a century doodling, tinkering, designing, inventing and creating, among other things, a flat pack house, a foldable boat, a 42-foot-high tree chair, plastic bike cars, wearable shelters, high mileage trikes, wooden speedboats, a $6 shelter, origami boats, micro RVs and bike campers.

He regularly films himself building and testing his latest creations for his youtube channel and sells plans for much of his work on his website ElkinsDIY. Despite his frustration with our current culture of buying and rebuying rather than fixing and building, he hopes to inspire future generations to enter his world where doing-it-yourself makes the ride, sail, night’s sleep so much richer.”

Hempcrete…

01) Hempcrete

“Hempcrete or Hemplime is bio-composite material, a mixture of hemp hurds (shives) and lime (possibly including natural hydraulic lime, sand, pozzolans) used as a material for construction and insulation. It is marketed under names like Hempcrete, Canobiote, Canosmose, and Isochanvre. Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the brittleness of concrete and consequently does not need expansion joints. The result is a lightweight insulating material ideal for most climates as it combines insulation and thermal mass.

Hempcrete has been used in France since the early 1990’s to construct non-weight bearing insulating infill walls, as hempcrete does not have the requisite strength for constructing foundation and is instead supported by the frame. France continues to be an avid user of hempcrete; it is growing in popularity annually.

Like other plant products, hemp absorbs CO2 from the atmosphere as it grows, retaining the carbon and releasing the oxygen. Theoretically 165 kg of carbon can be absorbed and locked up by 1 m3 of hempcrete wall during manufacture.

The typical compressive strength is around 1 MPa,[6] around 1/20 that of residential grade concrete. It is a low density material and resistant to crack under movement thus making it highly suitable for use in earthquake-prone areas. Hempcrete walls must be used together with a frame of another material that supports the vertical load in building construction, as hempcrete’s density is 15% that of traditional concrete.

Limecrete, Ltd. (UK) reports a fire resistance rating of 1 hour per British/EU standards.

In the United States, permits are needed for the use of hemp in building.”

Can You Build a House With Hemp? – National Geographic:

“Growing industrial hemp was illegal in the United States after 1970 because the industrial plant and marijuana were considered to be the same, when in fact they are different varieties of Cannabis. In recent years, some states have changed their laws, allowing farmers to start growing industrial hemp, which is used in everything from clothing to nutritional products to building materials. Oregon grower Cliff Thomason says growing and processing hemp was stymied because it was illegal, but now a knowledge base for best uses can grow, along with the plants. View a hemp home constructed using hempcrete, a building material that advocates claim is mold resistant, breathable, and eco-friendly.”


A Stunning Small Home Made From Hemp:

“Hemp is a building material like no other. It has incredible thermal properties, is environmentally friendly, rat and insect proof, fire and earthquake resistant and is an affordable way to build. Plus, the end result looks amazing!

After loosing her father to mesothelioma (a cancer caused through exposure to asbestos), Tiffany studied building biology, and together with her husband Michael, set about finding healthy ways of constructing a non-toxic small home for their young family.

Introduction to Natural Hempcrete Construction Methods:

“This webinar is designed to introduce participants to the materials and techniques required to use hempcrete as a building insulation material. Based on the book, Essential Hempcrete Construction, we will examine the material properties and specifications for hemp and for a variety of binders, and look at sourcing options for these materials. Mix ratios, forming systems and material placement will also be covered, including the use of hempcrete as sub-slab, wall and roof insulation. We’ll also cover the material costs and labour inputs for using hempcrete, as well as the equipment required to mix and place. Finishes for hempcrete walls will also be covered. Finally, the webinar will examine the building science implications of using hempcrete, including thermal performance, moisture performance and air-tightness.

Lessons Learned

– Understand the basic material composition of hempcrete, and learn how to source the materials.
– Understand the different mix ratios and resulting densities of hempcrete mixes, and how, why and where in a building each might be used.
– Understand the costs for materials and the amount of labour required to mix and place hempcrete.
– Understand the building science parameters of hempcrete, including thermal and moisture performance and air-tightness.

01) Farming Under the Sea


“Seventy miles off the coast of mainland Japan is the small island of Okinawa, home to some of the most unique seaweed in the world. Mozuku is a rare underwater delicacy found off the mainland coast. Each fall, farmer Tadashi Oshiro uses a special technique to sustainably harvest the seaweed. His one-of-a-kind farming methods were passed down to him by his father, using a process that allows the mozuku to grow without creating additional waste. And although changes in the environment leave the future of mozuku uncertain, Tadashi continues to uphold his family’s legacy.”
