RAIN CLOUD SEEDING

By firing flares from aircraft that carry salt based substances (Silver iodide, potassium oxide and dry ice), which draws water into prospective clouds, seeding can effectively make rain from a cloud.After almost tripling its yearly number of cloud-seeding aircraft over the previous six years, the UAE is a pioneer in this sector and intensifying its effort to make it rain. Even if in many areas of the nation they ae expecting brief, heavy downpours, efforts to increase precipitation in a generally parched region remain vital.

Their main worry is that the immediate goal of rain enhancement is to increase rainfall, replenish groundwater, and increase freshwater supplies, an issue shared by so many other dry nations.We must not overlook the wider and more extensive effects of rain on tourism, food and water security, and weather regulation.

The UAE conducted 311 cloud-seeding missions in 2022, clocking up close to 1,000 flying hours.

The UAE Research Program for Rain Enhancement Science has challenged the world's top thinkers to develop novel strategies for boosting rainfall.

As part of the study, scientists use artificial intelligence (AI) to increase precipitation. The best times and places for cloud seeding will be determined using an advanced framework that combines satellite observations, ground-based weather radar data, rain gauges, and numerical weather forecast projections.

Articulated Robot In Water Pipe

During CES 2023, Acwa Robots didn't waste any time. The French start-up took home three innovation awards at the tech expo for its autonomous robot that searches for and identifies water pipelines and any of their potential issues. Acwa Robots have created the first intelligent machine capable of navigating water networks entirely on its own.

Robots are the key component of the system because they can adapt to a harsh environment (up to 300 PSI of pressure, flowing water, etc.), cause little disturbance to services and water quality, and provide a strong foundation for a wide variety of sensors.

The technology, which is based on the fusion of several data sources, enables the establishment of a precise network travel path in a single pass and the association of this route with the data captured, such as measurements and photographs.

Pathfinder, Acwa's first autonomous robot, can go through the center of the water supply system without interfering with the flow of water to consumers.

The operational findings include locating the pipe with centimeter-level precision, followed by a thorough evaluation of residual thicknesses, corrosion, and microcracks. Data on the quality, pressure, and hydraulics of water follows in third.

In water delivery networks, nearly 120 million m3 of water are lost annually. This loss is mostly caused by pipe damage, and these clever individuals have THE answer!

Sono Luminescnce

Using 15,000 km/h ballistics experiments with an 18 millimeter diameter bullet that can vaporize water, supersonic scientific instruments are required in a water tank in order to examine the Sono luminescence.

This uses a 12-meters long apparatus called a ‘two-stage light gas cannon’. The devices contain two independent phases of propulsion, which leads to quicker launch rates (scientists often employ them to push items to imitate meteorites striking the atmosphere).

Although the impact is tremendous, it would be too quick for the spectator in the room to see with their unaided eyes.

Instead, a high-speed camera that can record up to 200 million frames per second is used to document the effect. For comparison, a smart phone ‘sees’ roughly 300 frames per second, compared to the equivalent of 30 frames per second for the human eye.

The speed of sound in water is more than four times faster than that in the air. When a liquid swiftly collapses as a consequence of a sound wave, the process is known as sonoluminescence. Researchers have been fascinated by this phenomenon for decades because of its potential to develop a waste-free energy source.

The bubbles may also achieve extraordinarily high temperatures and pressures for small periods of time.

An intriguing ballistic exercise. Let’s continue to observe what’s next…
