BELVOIR CHAPTER CHAPTER - Dec 16, 2021

The chapter is excited to announce its inaugural Escape the Planet hackathon event. Developed in conjunction with the AFCEA Northern Virginia Community College (NVCC) Student Chapter, AFCEA International, representatives from military academies and Fairfax County Public School faculty and high school students, Escape the Planet is a series of basic coding challenges built around a space exploration mission storyline. The challenge engages middle school students to assist the fictional Belvoir AFCEA Space Alliance (BASA) on their mission of discovery to Planet X to bring back recently detected evidence of "proof-of-life." This pilot effort was held December 16 - 17 and with support for ongoing coding curriculum being taught at each of the competing schools with the hope of seeding future interest and participation in Science Technology Engineering Arts & Math (STEAM) events.  As part of the ongoing mission of the chapter, grants are being offered to each of the competing schools to help further their STEAM curriculums. Upon receipt of their BASA support mission, students from Belvoir Upper School and Walt Whitman Middle School formed Mission Specialist teams. Each Mission Specialist team will have a Ground Support Team comprised of AFCEA NVCC students, AFCEA Emerging Leaders, U.S. Coast Guard Academy cadets and members of high school cyber clubs.  Students at Fort Belvoir Upper School in Fort Belvoir, Virginia, familiarize themselves with micro:bit devices that will be used in the Escape the Planet hackathon in December. Students at Fort Belvoir Upper School get a first look at micro:bit devices to be used in the Escape the Planet hackathon in December.

Cool Demo of Trailers and Tongue Weight Safety

In addition to consideration of vehicle length vs trailer length, knowing how to balance the weight of your trailer relevant to the trailer axle(s) is very important, particularly for safety.

Artificial photosynthesis

Most of these devices lose efficiency the longer they work. This one gains it.

Plants are living things, and like all living things, they need energy to grow, reproduce, and just keep on living.

Most harvest this fuel through photosynthesis, using solar energy to convert water and carbon dioxide into chemical energy useful for life.

Now, researchers are homing in on an artificial photosynthesis device that could let us do the same trick, turning sunlight and water into clean-burning hydrogen fuel for our cars, homes, and more.

What Is Artificial Photosynthesis?

Solar cells already let us convert sunlight into electricity. Artificial photosynthesis devices, however, use sunlight to turn water or carbon dioxide into liquid fuels, such as hydrogen or ethanol.

These can be stored more easily than electricity and used in different ways, allowing them to substitute
