Five hydrogen-powered Coradia iLint trains, built by Alstom, are operating in Lower Saxony, Germany. Nine more will be added in the coming months. The trains use hydrogen fuel cells to react stored hydrogen with oxygen from the air to produce electricity, with clean water vapor as the only byproduct. The electricity is used to turn electrical motors attached to the train’s wheels.

“Alstom says the Coradia iLint has a range of 1,000 kilometers, meaning that it can run all day on the line using a single tank of hydrogen. A hydrogen filling station has been set up on the route between Cuxhaven, Bremerhaven, Bremervörde and Buxtehude.” (Link)

Tubes or solid state transistors in audio playback systems? There’s been a decades-long debate over this in the audio world. Solid state measures better. Tubes usually measure worse and yet many people will tell you that tubes sound better. Personally, I prefer to use tubes at the preamp level. Ken Rockwell has written a good article on this subject.

The spike protein found on the outside of the SARS-CoV-2 coronavirus can damage the blood brain barrier and lead to what’s been called “leaky brain syndrome” which can cause neurological problems. I wondered if there are lifestyle changes that could help promote the health of the blood brain barrier. I spent some time researching this and here are my findings and what I’ll be targeting.

The number of bee colonies in Michigan are up 50% since 2018. This is significant because for the last 20 years, the number of bee colonies in Michigan were in decline. The pollination that bees provide are necessary in order to grow many types of fruits and other foods for human consumption. “The leading cause in declining populations is believed to be exposure to pesticides, insecticides, parasites, and pathogens, as well as limited sources of nectar and pollen.” (Link)
