New aluminum casing

Corsair, a well-known computer accessories manufacturer, has been extending its product range since April with the all-new Obsidian 450D mid-tower enclosure that will be available at an affordable price.

The housing measures 494 x 210 x 497 mm and weighs 7 kilograms, made from brushed aluminum and designed to provide high airflow, so it is not only elegant but also very functional. Two AD140L 140 mm wind turbines are installed under the front panel grille to cool the components.

On the back there is a 120mm AF120L fan, and in order to increase the efficiency of the cooling system, we can install an additional five other fans.

We also do not have to limit ourselves to air cooling and we can decide on a liquid cooling system. The manufacturer anticipated this by providing enough space to install a 360 mm radiator on the upper panel, 280 mm front and 240 mm on the bottom of the enclosure.

As far as the number of bays is concerned, the enclosure has two 5.25 “seats and three 3.5” / 2.5 “and two 2.5” bays directly behind the motherboard. Of course, all the bays have snap fasteners.

Sewage treatment changed to a power plant

Sewage flowing from thousands of households, until now, has only been purified, turning them into drinking water. The US company DC Water has decided to use it in yet another way and launched a completely new Blue Plains complex, which, in addition to sewage treatment, also produces electricity.

The complex was built in the District of Columbia and, as it is owned by its owner, sewage flowing from all over Washington, is used to generate electricity. Power generation capacity is estimated at 10 MW, which should be sufficient to supply about 8,000 households with a large profit.

The wastewater treatment plant utilizes a hydrolysis technique to process organic material into methane. This in turn is used to drive turbines that generate electricity. Its production takes place in large 24-meter silos, which each year can process almost 15 million liters of sewage. The by-product of this process are biological residues that can be used as organic fertilizer for agricultural production, so this is an added benefit of this idea.
