When it comes to potential human colonies on the Moon or Mars, nuclear reactors and solar panels are usually mentioned as the main source of energy. However, in the case of Mars, there is another option.

Colonists on Mars could build wind turbines to extract energy.  This option can be effective.

In certain areas of the Red Planet, energy can be obtained through wind turbines, a new study shows. More specifically, we are talking about providing energy for six colonists who can live and work on Mars all year round. True, here, in addition to wind energy, solar energy will be needed. But the bottom line is that these calculations were carried out for areas closer to the poles, where solar energy alone is extremely difficult to manage.

As you know, the Martian atmosphere is extremely rarefied. In fact, its density is only about 1% of the Earth’s, and the winds on Mars correlate with Earth’s in about the same way. However, this is enough to turn properly designed turbines and generate power.

Previously, it was believed that it was completely unprofitable to use wind energy on Mars, but such studies were carried out only for certain zones. In the new study, the scientists adapted the global climate model, which was originally developed for the Earth, to take into account the features of Mars. They used detailed information about Mars, including terrain, dust levels, and solar radiation in various regions. As a result, a model was built for different wind speeds on the planet, at different times of the day, in different seasons and even years.

As a result, calculations showed that wind energy can perfectly complement solar energy, and in some individual regions even be the only source of energy. Such a source has the maximum efficiency along the edges of Martian craters and volcanic uplands.

True, all this is only theoretical research, since the construction of wind turbines on Mars, taking into account the transportation of the necessary components, is unlikely to make such an option more expedient than solar or nuclear energy.

This Geely crossover can accelerate to 100 km h

The Chinese resource Autohome has published high-quality images of the Zeekr X compact electric crossover (Zeekr brand is owned by Geeky). It will be the brand’s third model after the Zeekr 001 premium hatchback and the Zeekr 009 minivan.

The Zeekr X has some things in common with the Zeekr 001, but in general the crossover has received an individual look. Of the features – the absence of door handles, frameless windows, “muscular” sidewalls and a straightened roofline for more headroom for rear passengers.

The Zeekr X will be based on the Geely SEA (Sustainable Experience Architecture) platform, which is also used by Volvo. Despite its compactness (dimensions – 4450 x 1836 x 1572 mm), the car will be quite spacious inside, as the wheelbase is 2750 mm long. For comparison, the current Hyundai Santa Fe with a length of 4785 mm has a wheelbase of 2765 mm.

What will be the traction batteries and electric motors – one can only guess for now, but Geely has already officially announced that the Zeekr X will accelerate to 100 km / h in 3 seconds.

Verified online whistleblower Ice Universe posted new photos on Twitter showing the optical and digital zoom capabilities of the Samsung Galaxy S23 Ultra flagship smartphone.

The pictures were taken with an ultra-wide-angle camera (0.6x), a main module (1x), as well as two telephoto lenses with 3x, 10x, 30x and 100x zoom.

Galaxy S23 Ultra, 0.6/1/3/10/30/100x. 30x zoom is beyond me. This is unscientific. Haha.

It can be stated that at 30x zoom, the quality of the images remains quite high for publication in social networks without visible blurs and loss of detail.

In addition, two photographs are presented, the second being made by cropping the original image.

Samsung Galaxy S23 smartphones may differ in speed versions with

As it became known, the versions of the Samsung Galaxy S23 smartphone equipped with 128 and 256 GB of flash memory differ in the type of this very memory.

The 128GB version uses slower UFS 3.1 memory. The 256GB version of the Galaxy S23 uses the new UFS 4.0 memory. In both cases, new LPDDR5X RAM is installed.

Allegedly, the base version may be slower in various scenarios than the 256GB version of the Galaxy S23. UFS 3.1 has a sequential read speed of 2100 Mbps and a sequential write speed of 1200 Mbps, while UFS 4.0 has a sequential read speed of 4200 Mbps and a sequential write speed of 2800 Mbps.

There is evidence that Samsung does not produce 128 GB UFS 4.0 memory chips. Only Kioxia makes 128GB UFS 4.0 memory, but even those don’t reach the required speeds. Therefore, Samsung decided to use UFS 3.1 flash memory for the lower version.

Samsung is offering a free upgrade for those who pre-order the Galaxy S23 series in many countries. For example, if you order the 128 GB version, you can get the 256 GB version.
