Artist impression of the planet Venus in a remote future after terraforming, with oceans and continents, cloud patterns and an impressive ring system

The Rings of Venus

Terraforming is the modification of a planet in such a way that terrestrial life can thrive there. One should not underestimate such an enterprise; the terraforming of Venus or Mars is a huge project that will take centuries, if not millennia. But on which of our two neighboring planets is such a project the most promising? They both have their pros and cons, but on this page I mainly want to talk about Venus. Sister planet This closest planet in our solar system looks suspiciously like Earth, at first glance. With a diameter of 12,104 kilometers, Venus is only a… Read More

Getting Used to a Terraformed Moon

The last few weeks, I have once again been busy with an old hobby of mine: terraforming. A word that the spelling checker does not even know, but in science-fiction one can read it quite often: it’s about making other planets more friendly for lifeforms from Earth by adjusting the temperature and the atmosphere. Mars and Venus The terraforming of Mars is actually not that complicated. Simply pumping CO2 and other greenhouse gases into the atmosphere will start a runaway greenhouse effect that turns up the heat and thickens the atmosphere. On our homeworld we are already practicing, unintentionally. What… Read More

Sailing on the Solar Wind

You can state by now that the wind is a recurring theme in my work. That’s shown most clearly by my triptych about wind energy on the North Sea. But also my plea for the rebuilding of windmill De Noord at Oostplein in Rotterdam fits perfectly into that story. Probably not everyone realizes that there’s wind also beyond the Earth’s atmosphere. Another kind of wind, though: solar wind. The particles from which the sunlight is composed exert force on objects that are illuminated by it. Johannes Kepler was, in the 16th century, the first to realize this when he studied… Read More

3000 Windmills on the Wall

We’re on a planet that is close to its primary and has a molten core, a substantial atmosphere, and a large natural satellite. Any species that can’t develop a sustainable energy infrastructure on such a planet doesn’t deserve to escape its gravity well. This quote from my friend Shaun Moss tells exactly what it is all about: we could be much worse off. If that star would be further away solar panels would be useless, without the atmosphere there is no wind, if that core has cooled you can forget geothermal energy and without such a decent size moon like ours tidal power… Read More
