🔮 What is a marble?

In my world, a marble is a metaphorical container for a note that I want to share and shape with you. It can be a sketchy idea, an insight, a piece of knowledge, or a question that I consider valuable for my life's ongoing dialogue.

These marbles are never perfect and always a snapshot of a given moment. So, please, feel free to add your perspective at the ⬇️ bottom of the page. I try to follow the 🔮 principles for media movement building.

Read more about my intentions in 🔮 this marble.

In the past, I didn't have a way to share ideas or insights with others. This marbles website is the manifestation of my desire to share intentionally with the world. If you want to do it too, let me know. I can help you.

CO2 levels in cars

I have been traveling with my air quality measurement device for 2 years. While public buildings’ air quality is highly controlled by law (has to be below 1100 ppm), private spaces are not, including cars and air conditioning systems for private houses.

Because CO2 is invisible and odorless, it is very hard to understand its effects because there are so many toxins around us that can make us feel nauseous - e.g. coffee, plastic fumes, car rides, work stress.
