Travel without flying

  I’ve now been to several places in the U.S. New York, St. Louis, Dallas and San Antonio and I can say I had a real cultural shock . After living in Sweden and Canada (Montreal), the U.S. feels like the far edge of the spectrum in terms of urban planning, culture, safety nets, food, roads and public transport. Basically everything looks and feels exactly as chaotic as it seems and I expected more from the world’s biggest economy. Let’s be fair: the U.S. is enormous. But still, numbers are numbers. USA GDP per capita: $89,105 Sweden GDP per capita: $74,900 Some might argue the U.S. is too big to keep everything as neat, clean, and well-organized as Sweden. But let’s look at my own invented metric GDP per square kilometer : USA: $3,102,347 / km² Sweden: $1,775,902 / km² So by this measure, the U.S. has almost double the dollars per square kilometer . Yet paradoxically the roads are full of potholes old buildings are collapsing next to fancy hotels and “newly built”...

Globalized World We live in a strange contradiction. On one hand, humans invented nations, borders, religions, gender roles, and money, concepts so “real” they exist mostly in our collective imagination. On the other hand, local societies often had to endure very real hardships: closed-minded living, few opportunities, and self-imposed cages of limitation. Then, for a glorious moment, salvation seemed near: the internet arrived, international organizations popped up, borders softened, and the “Union of Countries” type projects promised free movement. The world felt open. Of course, nothing global comes without side effects. Alongside global trade and collaboration came global tax loopholes, worldwide criminal syndicates, and scams that can now reach everyone, everywhere, from anywhere . Online Scams 2.0 Online fraud isn’t new. What is new is how easy it’s become. In the beginning, only a few highly skilled nerds knew how to exploit digital cracks in the system. Today? Anyone with a Wi...

  Simulation Creates Realities I can see a near future where humans stop smashing things in real life just to see what happens. No more expensive crash tests, no more wind tunnels sucking up billions of dollars, no more logistic and production nightmare on construction site or “oops, we broke another robot.” Instead, simulations will do the heavy lifting. Immense AI databases will crunch the properties of materials down to the atomic level and give us the most precise outcome imaginable. And honestly we’re already halfway there. Today, companies use AI to simulate how robots move, or to teach one how to do a backflip. Is that a useful feature? Probably not. But hey, at least it’s cheaper to fail in virtual reality than in the factory, where “oops” means six months of repairs and a crying engineer. The result? Fewer broken robots, fewer wasted weeks, and a lot more laughing at digital screw-ups before trying them in real life. We are heading into a world where we trust the s...

Hello, world long time no see 😊s ince January 2021, when I paused blogging, it feels like I lived another life. On the road I met an amazing girl who became my wife. We moved from place to place and eventually landed in Stockholm, Sweden, where routine and daily challenges took over. We divorced about half a year ago for for the same reason many couples divorce, the usual mix of personality, feelings, and mindset. In the same time, I got deep into tracking and improving my health, and the wave of new AI tools surprised us all with what they can do. The pace of change is crazy. In these four years my awareness grew a lot, and since June 2025 I’m back on my path, exploring new places. What’s best for whom when crossing the ocean                Today I’m in Canada. I didn’t take the “usual” way I would’ve liked I took the plane. As a curious note, flying pumps out far more CO₂ than a sailboat would, and it adds a bit of extra radiation to the...

As we know space is quite a hostile environment. Very cold, no air, no pressure, no gravitation and without natural resources yet people managed to colonize the low orbit of the Earth.  To lift one kg to space costs about 2700$/kg or less for the cheapest cargo carriers as Falcon 9 of SpaceX [1] . It is very expensive if we compare how much it costs to send one kg on an airplane which is above 4$/kg [2] .  The price and unfriendly ambient, placed people in the corner to find the solution of water management in space. People were pushed to reconsider what is water and how to use it when the only water source is on the Earth. The previous knowledge of personal hygiene and disposal of urine had endured rigorous scientific researches and tests to ensure the basic needs of water in space. The water system in space is nearly perfekt in terms of sustainability. Personal hygiene is performed with less water than ever before yet without compromising the health of astronauts.  The ...

            It has been a while since my last appearance on this page which wasn't caused directly by me. Such a decision to retract from writing, I made only because I faced covid-19.  Covid-19 after being around for one year still ravages outside the window and I thought perhaps it is time to give a new life and meaning to old forgotten things, namely to my abandoned travel blog.       Idea of writing a book was circling around my head for many years though low esteem in my writing skills and limited time by routine work wouldn't allow me to break the ice into initiation of putting down my reflections.      To achieve my goal of writing I quit my job which  generated the precious free time for drafting and the writing skills I somehow achieved with my traveling blog.      I am still far away to master the writing craft which wasn't anyway my final goal. I aimed ...
