Schlagwort: Water

Aus Nebel Wasser machen

In Peru ist sauberes Wasser ein kostbares Gut, dass nicht überall ohne weiteres verfügbar ist. Abel Cruz Gutiérrez hat ein System entwickelt, mit dem er 200 bis 350 Liter Wasser am Tag aus dem Nebel holt. Great Big Story hat ihn besucht.

Millions of people in Peru lack access to safe water and sewage services. But Abel Cruz Gutiérrez has a solution. Gutiérrez, president of the „Peruvians Without Water“ association, uses an ingenious system of „fog catchers“ to make water accessible to residents of Lima’s low-income neighborhoods. The fog catchers resemble large rectangular sailboat sails, which are composed of nylon nets that trap microdroplets of water. The nets are set up along the foggy areas of coastal Peru and are connected to pipes, which collect the water for larger storage tanks. Residents can then use this water as irrigation for crops or to raise animals. And while the water isn’t currently drinkable, Gutiérrez is working on a solution to that as well.

Hahn oder Flasche

Ich selber habe nie verstanden, warum Menschen sich hierzulande Wasser in Flaschen kaufen, das nicht sprudelt. Wenn das nicht irgendwelche gesundheitlichen Gründe hat. Zumal man beim Einkauf ja auch auf Menschen trifft.

Ultra Slow Motion: Schwingende Stimmgabel trifft auf Wasser

Bei 30.000 Bildern pro Sekunde.

„This is what a tuning fork in water looks like in ultra slow motion, filmed with the Phantom V2512 Ultra High Speed HD Color Camera.
After watching Destins video on walking water a couple days ago i remembered that i had encountered the same phenomenon in a previous shoot, so i though about which shoot that was and wala, i remembered it was the tuning fork in water in ultra slow motion.“

Wasser färben auf der ISS

Once again, astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
