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
Artificial photosynthesis machine improves itself over time.
Kristin Houser at Freethink.com
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.
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

Tribute to JC Parry
![]() |
| JC Parry, Aviation and Engineering Teacher |
The STEM acronym was created in Arlington in 2001. And JC Parry was an important part of just about every STEM initiative in Northern Virginia in that first decade and beyond. He pioneered many statewide courses in Engineering Education, and participated in all of our regional Math in CTE (Career and Technical Education), and STEM and CTE programs promoting interdisciplinary teaching.
Of course, as an Air Force Captain and engineer, JC inspired many young pilots in Arlington, who secured their initial pilot license through him. Many also had their first flying experience with JC, as he regularly volunteered his time on weekends at the Manassas Airport.
JC was a foundational instructor for the first Governor's Career and Technical Academy (in Arlington), the Governor's STEM Academy that became the foundation for Arlington Tech in 2016. He was a leader in dual enrollment initiatives with Northern Virginia Community College, and he was my go-to teacher for piloting initiatives for the new Northern Virginia STEM program, Systemic Solutions, back in 2013. He helped us significantly with the many other regional initiatives, always offering his classroom for Chamber of Commerce Education and Workforce meetings, many pilot programs for Arlington Community Learning, and connecting parents and the businesses community to the Arlington Career Center.
We started teaching together at the Career Center together at the turn of the century, and even shared an office for several years.
