Brad Horn: Alexander Kendrick invents low-frequency antenna which works in caves

We’re tempted to follow the editorial lead of others who’ve covered this story – emphasizing that Alexander Kendrick is 16 years old and won a science fair prize for his new low-frequency radio system. We agree that it’s more remarkable that he’s only 16 – but think this would be a remarkable achievement if he were 61.

It’s our impression, based on Brad Horn’s excellent coverage, that this system is lightweight, portable, easily assembled, and relies on relatively inexpensive components.  Check out Brad Horn’s piece on NPR, Texting Underground Can Save Lives And Caves.

Caves are some of the last places on the planet left to explore. Though caving is relatively safe, if something goes wrong deep inside the Earth, a rescue can take days — in part because cell phones and walkie-talkies don’t work underground. But a remarkable teenager in New Mexico has invented a device that may significantly speed that process with the ability to text from underground caves. The young man’s invention may have other applications, as well.

We hope to have an update with images and more information in the near future.
