Casual reminder that in one of Leonardo da Vinci’s many notebooks containing innumerable artistic and scientific sketches and notes of incomprehensible important, there is a sketch of two penises with legs and tails walking towards a crudely drawn anus.
The sketch was most likely done by Leonardo’s apprentice Salai, who was not only very likely one of Leonardo’s lovers, but who was also infamously mischievous. Better yet, the anus is literally labeled “Salai.”
So either Salai drew these while Leonardo wasn’t looking just to annoy his boyfriend, or Leonardo himself put actual time and energy into drawing these. Either way, the human race is truly blessed to have made such a discovery.
There are dick drawings like the ones you see on desks in school in Leonardo da Vinci’s notebooks. Please cherish this information.
In the midst of exploring Renaissance Italy history for reasons, I have found a wonder.
Here Comes the Sun: Mirrors in orbit would reflect sunlight onto huge solar panels, and the resulting power would be beamed down to Earth. Image: John MacNeill
Imagine looking out over Tokyo Bay from high above and seeing a man-made island in the harbor, 3 kilometers long. A massive net is stretched over the island and studded with 5 billion tiny rectifying antennas, which convert microwave energy into DC electricity. Also on the island is a substation that sends that electricity coursing through a submarine cable to Tokyo, to help keep the factories of the Keihin industrial zone humming and the neon lights of Shibuya shining bright.
But you can’t even see the most interesting part. Several giant solar collectors in geosynchronous orbit are beaming microwaves down to the island from 36 000 km above Earth.
It’s been the subject of many previous studies and the stuff of sci-fi for decades, but space-based solar power could at last become a reality—and within 25 years, according to a proposal from researchers at the Japan Aerospace Exploration Agency (JAXA). The agency, which leads the world in research on space-based solar power systems, now has a technology road map that suggests a series of ground and orbital demonstrations leading to the development in the 2030s of a 1-gigawatt commercial system—about the same output as a typical nuclear power plant.
Nasa is a major player in space science, so when a team from the agency this week presents evidence that ”impossible” microwave thrusters seem to work, something strange is definitely going on. Either the results are completely wrong, or Nasa has confirmed a major breakthrough in space propulsion.
