Symbiosei has launched in Dahab (Egypt) an online broadcast of meteorological data, including - wind speed and direction.

Extra cooling for Raspberry Pi

Why?

And how to optimize air exchange costs with a Smart Home

Why is it better to open the curtains at night in a hot climate? And why do adventure novel heroes always prefer to sleep under a roof?

A beautiful garden and a sustainable ecosystem are far from the same thing. How can these be combined?

And why do clones of pop celebrities rarely replicate the success of their prototypes. A bit of N-dimensional geometry to better understand the intricacies of how complex systems work

A draft, even a weak one, destroys the thin protective layer of warm and humid air directly adjacent to your skin. As a result, you start losing heat much faster, up to the point of hypothermia. And this can harm your health, sometimes quite significantly

In a poorly insulated house with cold walls and freezing corners, there will be no real comfort. Below is a detailed explanation of why

Hypothermia itself does not lead to illness. BUT! Hypothermia, even local, quickly reduces immunity, and with weakened immunity, it is much easier to catch an infection. And if it were just a cold..

Dry skin? Vascular problems? Cracked lips? Constant allergies and asthmatic children? Perhaps the air humidity in your home is far from optimal

And why it's so important to have a proper air humidifier with a tank of at least 5 liters in your home during winter

If clothing (or a blanket) doesn't fit snugly enough against the body, a draft can form between the fabric and the skin. Often, it's strong enough to cause inflammation

Three Key Criteria for Selecting a Humidifier, in Our Opinion

Technologies for producing artificial meat and cheese, plant-based protein, aeroponics, and tabletop greenhouses for growing greens right in the kitchen are rapidly gaining momentum

The amount of solar energy received by plant leaves varies drastically - by a factor of tens - depending on whether they are in shade, partial shade, or direct sunlight. That’s why correct positioning of light sensors is so important.
