Evolving Gas at Depth

ElectrolysisIcon

Under test, decomposition of water into oxyhydrogen gas (or HHO gas) yielded a slightly higher efficiency at greater pressure than in open atmospheric pressures. More testing is needed to identify the exact cause of this variation. Continue reading

First 3D Printer Fully Recovered

Hob

Over the summer, students moving our 3D printers to and from the AggieSTEM summer camp sessions accidentally dropped three 3D Printers into a pit due to on-campus construction they were trying to lift the cart over, resulting in various types … Continue reading

Repair Teaches Many Things

Rechargeable LiPo button power cells (old and new)

Repairing instead of replacing gives opportunities to teach many things from engineering to electronics to sustainability. Kids learn that they can repair and recover items that would otherwise fill our landfills and consume more resources to fabricate replacements. Continue reading

#SciFund Round 2 Project B Support Results

#SciFund Round 2 Project B Icon

During the 2nd Round of the #SciFund Challenge, crowd-funded support was provided to test the artificial “Solar Seaweed” system, with very positive results after the open-water tests conducted in the Gulf of Mexico. The design was proven to work and additional areas for further research were revealed. Continue reading

Making Proprietary Generic, Reusable and Inexpensive

3D Printed Custom Refilling Funnel with Side Ports

Using a 3D printer and a few cents’ worth of plastic, one teacher can now refill proprietary printer cartridges for 1/20th the cost of a new cartridge using generic supplies. It took three tries to bypass all measures designed to prevent refilling by the manufacturer, but this involved only simple changes in a CAD program and a little time for reprints. Continue reading

Underwater Solar Panel Dive Test Results

Two divers were able to test the Solar Seaweed design in experiments conducted in the Gulf of Mexico off the coast of Corpus Christie, Texas. The design proved that submerged biomimetic photovoltaic (PV) solar panels can be operated underwater in shallow water deployments, with an interesting test result showing that near-surface panels capture light reflected from surface waves even when facing away from the sun. Additional tests will be needed, but this experiment proves the concept works. Continue reading
