The #Persian #qanat is an ancient #irrigation system developed around 3,000 years ago in #Iran to transport water from underground aquifers to the surface through a series of gently sloping tunnels and vertical shafts. image This system allows water to flow by gravity without the need for pumping, making it efficient in arid regions. Qanats begin with a mother well at an elevated location, and the #water is channeled through tunnels to outlets in settlements or agricultural areas. They support irrigation and domestic use, contributing significantly to the development of #civilizations in arid environments.

A sun trap is a landscape feature designed to capture #solar energy while shielding from cold winds, creating a warmer #microclimate. image This can occur naturally or be intentionally crafted, often in a horseshoe shape with taller plants at the back and shorter ones at the front. Such designs allow for the cultivation of tender plants that require longer growing seasons than the surrounding area permits. Sun traps are particularly beneficial in colder climates, enhancing #gardening opportunities and plant #diversity. #Permaculture #Nostr #Bitcoin #Grownostr #Landscape_Design #Garden
A #wind_catcher, also known as a #wind_tower or wind scoop, is a traditional architectural feature designed to provide #natural #ventilation and cooling in buildings, particularly in hot and arid regions like the #Middle_East and #Central_Asia. image How It Works: Capturing Wind: Openings at the top of the tower are aligned to catch prevailing winds. The air is directed downward into the building through vertical shafts. Pressure Differentials: Wind creates high pressure on the windward side and low pressure on the leeward side, facilitating airflow through the structure. Stack Effect: Warm indoor air rises and exits through upper openings, while cooler, denser air enters below, enhancing ventilation. Cooling Mechanisms: In some cases, air passes over water (e.g., #qanats) for evaporative cooling before entering the building.

Hey Guys. Please boost it. It must be broadcasted worldwide. Watch it and share it with people you know. The world feels like it’s heading in the wrong direction—rising costs, declining standards, and growing instability. The root cause?

The word "paradise" originates from the Old #Persian term pairi-daêza, meaning "walled enclosure" or "garden. image "This term is composed of pairi, meaning "around," and daêza, meaning "wall" or "to build". The #Greek adaptation paradeisos referred to royal parks and was later used in biblical texts to describe the #Garden of #Eden. Over time, it evolved into various languages, including #Latin paradisus and Old #French paradis, before entering #English.
