Navy Program PUMPs Up Hopes for Magnetic Propulsion

Posted on June 5, 2023 by Navarre Bartz

The Yamato 1, a sleek grey ship that looks vaguely like a computer mouse or Star Trek shuttlecraft. It has an enclosed cockpit up front with black windows and blue trim. It is sitting on land in front of a red tower at a museum in Tokyo.

The “caterpillar drive” in The Hunt for Red October allowed the sub to travel virtually undetected through the ocean, but real examples of magnetohydrodynamic drives (MHDs) are rare. The US …read more Continue reading Navy Program PUMPs Up Hopes for Magnetic Propulsion→

Wii XL is Twice as Nice

Posted on June 2, 2023 by Navarre Bartz

A white Wii console sits on a grey table in the vertical orientation with its front facing the camera and its back away from the camera at a slight angle to the right. Next to it is a 2x sized replica which dwarfs the diminutive console. A purple light runs across the back edge of the table.

The Wii was a relatively small console when it released, but it packed a big punch when it came to its game library and the impact it had on the …read more Continue reading Wii XL is Twice as Nice→

Keeping the Noise Down Under the Sea

Posted on May 24, 2023 by Navarre Bartz

A pinwheel sits in an aquarium to simulate an offshore wind turbine. Bubbles come up from the "seabed" to encircle it to demonstrate a bubble curtain with an image of a sound waveform overlaid with the video to show the sound confined to the area within the bubble curtain.

Since sound is the primary sense used by most ocean life, disruptions to the natural noise levels in the ocean from human activities can be particularly problematic for marine life. …read more Continue reading Keeping the Noise Down Under the Sea→

Bike Camper with Retro Flair

Posted on May 23, 2023 by Navarre Bartz

A blue work tricycle (single front wheel with platform between two rear wheels) sits on an asphalt path with trees and wildflowers in the background. A boxy, white camper with a front overhanging the bike seat is attached to the platform. It has a yellow stripe and curtains like many campers did in the 1970s. One white male is exiting the door of the camper while his brother is standing to the left of the camper by the bike seat.

As we’re approaching summer here in the Northern Hemisphere, thoughts naturally turn toward road trips. While most people do this in their car, the [Dangie Bros] built a 500 lb …read more Continue reading Bike Camper with Retro Flair→

3D Printed Aerospike was Designed by AI
