Lol, I like all the flamingos in the hugel. Also it's fascinating to see how much more green and lush the hugel is compared to the surrounding grassland. I wonder if they irrigate it

The hugel is designed to absorb and retain water better than flat ground!

Yes, exactly. I want to know if that difference in vegetation is solely due to the existence of a hugel or if it's also being irrigated.

Quote from: Just Have a Think
Agrophotovoltaics, agrivoltaics, or APV. Just like the name suggests, it's a way of combining photovoltaic solar panels with agriculture. In many parts of the world where fertile land is scarce, agriculture and solar developers have fought over available space. What each party might have been missing all along is that it could be more profitable for both of them if they work together instead. And that may also just be the answer to the existential crisis being faced by so many farms across the United States and around the world.

25-30 years ago a few hippies pooled their money together to buy 100 acres of degraded farmland in Wisconsin. By following permaculture design principles they've been able to grow enough food to pay off the mortgage, taxes, construction materials for their house, and raise two kids.

They started by planting rows of trees and perennial shrubs to create terraces down the hillside, with annual cash crops growing between the rows of trees. For the first several years they relied on income from the annual cash crops while they waited for the larger fruit and nut trees became established.

How to design roads that naturally make people want to slow down instead of just posting a sign and calling it good



It's time to end stroads. We should have streets and roads instead!

So I guess we should start buying cheap land in the desert 🤔

If you're going to live in a city, at least plant some trees!



Look at the striking contrast between this building and all of the others around it!

Potable water is important.

Solar-powered desalination device wins MIT $100K competition
Nona Desalination says it has developed a device capable of producing enough drinking water for 10 people at half the cost and with 1/10th the power of other water desalination devices. The device is roughly the size and weight of a case of bottled water and is powered by a small solar panel.
The traditional approach for water desalination relies on a power-intensive process called reverse osmosis. In contrast, Nona uses a technology developed in MIT’s Research Laboratory of Electronics that removes salt and bacteria from seawater using an electrical current.
The company has already developed a small prototype that produces clean drinking water. With its winnings, Nona will build more prototypes to give to early customers.
The company plans to sell its first units to sailors before moving into the emergency preparedness space in the U.S., which it estimates to be a $5 billion industry. From there, it hopes to scale globally to help with disaster relief. The technology could also possibly be used for hydrogen production, oil and gas separation, and more.

woah, portable low-energy electric salt & bacteria filters? that sounds way better than having to constantly replace carbon filters! or heating up water to the boiling point (distillation) or pumping the water to really high pressures (reverse osmosis)

Quote
The resulting water exceeded World Health Organization quality guidelines, and the unit reduced the amount of suspended solids by at least a factor of 10. Their prototype generates drinking water at a rate of 0.3 liters per hour, and requires only 20 watt-hours per liter.

WOW!  only 20 watts for a litre of clean water and you can get water from anywhere. it removes turbidity and salts
