Here's a cool demo I saw recently that allows a cyclist to specify risk tolerance for busy roads, based on traffic data. Take the direct, busy route, or the roundabout way, using bike paths where available. https://rc.nau.ed

Here's the LK-99 tie in: the most precise gravity meters in the world are superconducting meters, which require a lot of power (2 kW contonuous) to maintain a helium dewar at 4K. It's tough to make that a field instrument. A compa

Too bad Google gets the credit for the amazing https://www.shakealert.org system developed by the USGS and other public entities. Altering the user is the easy part, detecting the earthquake is the hard part.

Seems like more often than not I see them folded up, not in use. Even with the price of diesel. I wonder how much they save?
