One thing all cities should enforce for future builds(especially for skyscrapers), is bird-protection on windows.

In Canada, 16-42 million birds are killed by window strikes, and in the USA, that number goes up to 365 million-1 billion.

Sadly, one or two of those bird-shaped decals do not help, since the decals have to be no more than 2-inches apart.

“Window decals may help, but they must be placed no more than 2-4 inches apart in order to be effective. Birds will try to fly through larger gaps. This means that on large windows, many closely spaced decals may be necessary to deter bird collisions.” Audubon

Luckily, however, the fix for this window problem is easy. For the first example; there are bird-safe decorative window films and decals(they must go on the outside of the window).

The most common design is made up of several small white dots, while others are more decorative.

If decals will not work for you (they sometimes don’t last in cold climates), you can opt for permanent (and more expensive) window etchings.

Need an even less expensive option? You can make your own dots or designs using a Uni-Posca pen. The markings can be scraped off if needed. Just remember that the markings must be on the outside part of the window for them to work.

If more apartment complexes and skyscrapers used these or other solutions, we’d be a step closer to co-existing with nature.

Roads can cause major problems for wildlife, and not just from the danger of being truck by vehicles. With busy enough traffic, wildlife may avoid crossing at all, causing habitat fragmentation. In order to stitch habitats back together, wildlife overpasses, underpasses/tunnels, and viaducts are all used.

Typically, overpasses work better than underpasses for most wildlife, since not all wildlife is comfortable traversing into a dark (sometimes loud with traffic vibrations) tunnel. In comparison, the overpasses are typically made to feel like a hill for wildlife; with soil, grass, and trees added.

No matter what people build, however, it can help.

In most cases, the cost of building and maintaining these crossings end up being less than the cost of repairs, injuries, and cleanup that occurs when a vehicle strikes an animal.

I understand that not everyone will have access to a stream/river with fish, but I thought people might find this interesting anyways.

Do you have videos that stick with you? "Through the Kitchen Window: A Town Living with Water [Harie, Shiga] " is one that occasionally pops back in my mind.

In Harie, Shiga(Japan), water canals run through much of the town, and the people there use it to develop a mutually beneficial relationship with fish. 🐟

Imagine a pool of water that people use for washing fruits, vegetables, and dishes. That same pool has carp that call it home, and the carp eat the scraps and keep the water crystal clear. This could be inside the home or outside, but it is constantly added to by natural spring water, and the water exits in to a canal. This system is called “Kabata,” and has been used for over 300 years.

That running water then heads to rice flats, which benefit from the natural fertilizers the fish provide. That water then heads to wetland area, where the water is cleaned by reeds and other vegetation before entering a lake.

Within Arizona(USA) is a beautiful cliff-dwelling built by the Sinagua people in 1100-1425 AD. Montezuma Castle (renamed to this by colonizers) has around 20 rooms, and is built using a method that today people call “passive solar building.”

“In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.” Wikipedia

For the cliff dwelling, that included a design that ensured the buildings were hit with the heat of the low-winter sun, but protected from the high-summer sun by overhang. It also made use of ventilation, small windows and doors (to reduce temperature loss), and more.

This ancient knowledge is making a comeback in houses, but is really helping for greenhouses. Even in colder climates where temperatures can reach -40c(-40f), passive solar designs are enabling greenhouses to run all-year.

I know very few people in the world have access to hot springs, but I just thought people here might find this information as interesting as I do.

Japan:

Cooking Eggs:

In some other places, hot-spring pools can become a neighborhood egg-cooking spot. In Japan, these eggs are called Onsen Tamago (温泉卵), and are slow-cooked in the natural spring water.

The result is a unique custard-like texture in the yoke, while the whites are soft.

“It is said to have originated in Onsen Towns in Beppu, Oita prefecture. It is said that the first Onsen Tamago was made over 300 years ago when a traveler left his eggs in a hot spring by accident and found them cooked when he returned." MyFormosaFood

Steam Cooking

“It is a cooking method using high-temperature steam heat gushing from hot springs, and it has been used in Beppu since the Edo period. Just put the ingredients in a basket, put them in a pot where steam of about 100 degrees called “Hell Steaming Kettle” and cover it.” | Jigoku Mushi

At tables equipped with timers and hot-spring powered steam cookers, you can steam your own food.

Heating Greenhouses:

“Hot springs are used to heat greenhouses for different types of fruit and vegetables. At Atagawa Spa on the Izu Peninsula, the Atagawa Tropical & Alligator Garden cultivates tropical plants like banana trees and bougainvillea.” | Nipponia

By piping the heat into radiators, they can heat and humidify the greenhouses with no electricity.

Iceland:

Volcano Bread

Cooking rye bread with the help of a volcano has a long history in Iceland. All you had to do was dig a hole near a hot-spring, place the dough (which is in a container) in the hole, and burry it.

The boiling water will steam the dough to a dense but soft texture.

Hopefully you remember to mark where the hole is, but if you did, you will have freshly cooked bread with no need of an oven. As an extra bonus, you can also cook some eggs when you are there.

While it might look like those grapes are in weirdly-shaped bread, they are really in clay. A pair of clay bowls are made, and left to bake in the sun. When they are dried, they are ready to use.

“When each pair of rustic “earthenware bowls” is completely dried, around 1kg of ripe unbruised fruit are put inside, and then sealed with another serving of mud to form a single closed, air-tight vessel.” Farmizen

This is called a “Kangina” and is an ancient preservation technique still used in Afghanistan to this day.

The kangina are put somewhere cool (sometimes buried) and will remain fresh for up to 6 months. They are both eco-friendly, and effective.

Crafted by a potter named M Sivasamy, this clay pot was designed to help keep produce cool for days.

He made a cylindrical pot made out of clay with a tap on one side and an outlet to pour water on the other side. A smaller pot fits inside the bigger one where you can place your vegetables which is then covered with a lid. The technology is simple — the water in the pot remains cool keeping the vegetables fresh and cool. - BetterIndia

For places with no or limited electricity, this could help immensely. Especially considering terracotta(earthenware) clay is almost used worldwide.

I just thought people would find this interesting:

Within the Ukraine lives the Hutsul people. They are masters of a specific type of wool blanket technique called “lizhnyk,” which is made from Carpathian sheep wool.

Creating the blankets is a long and difficult craft, but the results are beautiful.

One of the most ingenious parts of their craft involves help from the river. A valylo is a river-powered wooden washing machine; which will beat the blankets until they are soft and lose their sheep-smell.

Thought to be a system over 100 years old, the valtoare/vâltori (whirlpool) in Romania works by channeling water into a large wooden funnel-like barrel. The funnel has gaps wide enough for water to flow out, but not wide enough for the cloth to slip through.

The force and angle of the water hitting the wood creates a spiral of water, which tumbles the clothes thrown inside.

Historically, people would rent the usage of these from the owner, with money, grain, or by working the land for however long it took the clothes to wash. Today, they are free.

“Today, whirlpools remain popular, especially among people from rural areas. They are used for washing wool fabrics free of charge, but people still like to contribute a small fee to the budget for repair and maintenance.” Peasant Art Craft

Prior to when electricity became common place, people were looking for other ways to make life easier. One of these inventions, the solar water heater, came in 1760, and boomed with popularity in the 1900’s for warm areas.

“In 1891, Clarence Kemp released the first ‘Climax’ solar water heater in Baltimore. He placed several water-filled iron elliptical tubes inside the box in series with cold water entering one side and warm water exiting from the other end. Multiple tubes avoided warm and cold-water being in close proximity, thus avoiding adverse heat exchanges.” PassiveHousePlus

These early models did have faults (such as heat lost, and poor resistance to frost, but continued to improve and build with popularity over time.

Eventually, for a complex number of reasons, solar water heaters disappeared and gas and electric took the show.

Today, this tech is making a comeback, though with modern touches.

"To help feed the country’s population, an inventor, Toufic Hamdan, created a commercial bakery to bake bread in solar ovens. The startup “Partners With Sun” has installed a solar convection oven on the bakery’s roof. The Solar Oven uses large silver mirrors to capture and magnify the sun’s rays to build heat. The heat is transported by a transfer fluid which is then used to help operate a convection oven, allowing it to reach a baking temperature of between 300 and 400 Celsius. The heat is used directly in food and beverage production. " Baking Bread in a Solar Oven | Happy Eco News

According to the company website, “The Solar Oven cuts up to 80% of the bakery’s fuel bill.”

I just thought I would share some different solar projects I think are interesting.

Terracotta Solar:

"Designed to be indistinguishable by the naked eye from regular terracotta roof tiles, “Invisible Solar” tiles are made to improve the energy efficiency of heritage buildings without compromising their historic appearance. They make each tile out of a non-toxic and recyclable polymeric compound they themselves developed, and the tiles allow for sunlight to pass into a hidden bank of photovoltaic cells without the human eye being able to tell they are translusent." | Good News Network

Apartment Balcony DIY Solar

If you have a sunny apartment balcony and have ever been interested in solar, there are many options; including some designed to look like privacy walls. It is supposed to be as easy as strapping on and connecting the panels, then plugging the system into your outdoor wall socket.

“In the best case scenario, a 600 W balcony panel pays for itself after just a few years,” said Hermann Dinkler, an energy expert at the German technical inspection association TÜV. With a shade-free southern orientation, an optimal inclination angle of 35 degrees without shade and 2,000 kWh of electricity consumption per year, a typical 600 W system pays for itself after about five years, according to German institute HTW Berlin. - PV Magazine

To find out if solar would work for your apartment balcony, make sure to do the calculations(such as with a solar panel calculator), ensure you have an outdoor socket, and check the rules of your building.

Solar Glass Bricks

These ones (amusingly) do remind me of the 1980s glass brick wall fad, but these are made to used to replace windows or other glass in office blocks, buildings and even bus stops. The inventors at Build Solar think they look better than solar panels and take up less space, so could be an eco-friendly alternative to current building materials.

Adding Solar to More Devices

The company Ambient Photonics showcased a bifacial solar cell. It can harvest from both the front and back simultaneously, and aims to charge small electronic devices; such as remote controls. It is supposed to work even in low-light, including indoors.

Its flexible and thin design means it could work in many different device types.

Funnily, the tech is reminding a surprising amount of people of the solar-powered calculators that used to be everywhere.

One of the easiest ways to help the planet might come from...human waste. 💩

Natural gas is a commonly used fossil fuel. The secret? Natural gas is mostly just methane; the same gas created from human waste.

In fact, toilets exploding can absolutely happen, which is why bringing a candle into an outhouse is a very bad idea. Some places even put this to use, such as using sewers to fuel street lamps(called sewer gas destructor lamps), which have the duel-purpose cutting down on smells and dangerous gas buildups

(Image Source)

There’s also more 💩 can do for us. For example…

• ⚡️Generate power (use the methane to replace natural gas).
• 🚗 Create fuel for vehicles
• 🔥 Create fuel for gas burners
• 🌱 Create compost (biosolids from the sewage treatment/methane plants) to help with phosphorus mining shortages

These options could greatly help with the transition from fossil fuels, and provide incentives for all cities to stop dumping raw sewage(yes, many places still do this).
