Barefoot College

I am impressed by “barefoot college“, where women from rural areas learn how to build solar systems. Women, who often cant read, get 6 months of hands-on-training in setup and maintenance of solar systems. They learn skills nobody in their village has, their men respect them, their children see them as inspiration. The college has Ghandi’s principles as basis.

Pentland Firth Underwater Turbine Tidal Green Energy Plant

The search for green energy sources motivates people to create genious solutions. Checkout the Pentland Firth sea turbine tidal power plant in construction by MeyGen.

I am happy to know that there is an effort happening to harvest this energy source.

I call it green energy as it doesn’t emit CO2. But I hesitated to call it renewable energy though, because, you know, tidal waves are powered by moon momentum, which is finally not renewable.

Question to physicists/astronomers: by slowing down tidal waves, what is the effect on moon momentum:

  1. Slowing down tidal waves reduces the strain the waves create on the moon. The moon looses less kinetic energy, it slows down less than without.
  2. Taking energy out of tides takes kinetic energy from the moon. It slows down.

But who said the sun is renewable. So I think I should stop nitpicking terms and just accept that “renewable energy” is a good layman term.

Dr. Megavolt wrote about his journey from physics PhD to pissing on the ground stake of a tesla coil at Burningman

Dr. Megavolt – a guy with a metal birdcage over his head getting zapped by a 1.000.000 Volt Tesla Coil on top of a truck at Burning Man. Also known as Dr. Austin Richards. His homepage: drmegavolt.com. He wrote a compelling story about how he became Dr. Megavolt, who co-created the act with him, trouble and joy they had, eventual break ups and hick-ups, and the ongoing joy he gets out of it.

Twoday to WordPress converter

I wrote a converter to take an export from twoday.net and write it into an XML file that wordpress will read.

If you are wondering if you want to move from twoday.net to a wordpress blog, and if you can program python to understand how this works and how to run it, then you may want to checkout this script:

I won’t support the code, other projects more interesting.

More about the reasons why I wrote this in the next blog post…
