Rockville Centre, New York – Students from around the world are invited to share their innovative solutions as part of the 2021 Spellman High Voltage Electronics Clean Tech Competition. This year’s competition theme is “Preserving Planet Earth” with the goal of bringing a wide range of participation in the fight against climate change. Students will compete in one of two categories: “Low Cost” and “High Tech.”
The first-place winners in each category will receive $10,000 in prize money; $7,000 for second, $5,000 for third; while fourth through tenth places will each be awarded $1,000.
Over $55,000 in prize money will be awarded to the top student teams at the Competition finals, which will be held on August 5, 2021.
The 2021 Spellman High Voltage Electronics Clean Tech Competition encourages scientific understanding of real-world issues and the integration of environmentally responsible energy sources. Registration for the competition is open through April 23, 2021, students submit their papers by April 28. Ten finalists in each category will be announced online on June 5, 2021.
“As we approach the 10th Anniversary of the Clean Tech Competition, the world is facing many challenges and young people will play a critical role in developing solutions. As sponsor of the Spellman HV Clean Tech Competition, we are ever more impressed and inspired by the student competitors each year,” said Spellman HV President Dr. Loren Skeist. “The submissions from high school students around the world continue push the boundaries and give us hope that we will be able to overcome energy and environmental challenges.”
“We encourage young people from around the world to participate and share their knowledge, ideas and passions for making a difference and preserving our planet for future generations. This competition provides a tremendous opportunity for young people to explore, achieve and interact with peers from different nations. We are certain the projects we see this year will be amazing and inspiring,” said Dr. Ray Ann Havasy, Executive Director of the Center for Science, Teaching and Learning.
Innovative ideas and solutions are necessary to promote sustainable energy use, preserve the planet, help resolve climate change and create healthier environments. The program is hosted and managed by Rockville Centre, New York-based not-for-profit Center for Science, Teaching & Learning (CSTL), led by STEM Crusader and Advocate Dr. Ray Ann Havasy and sponsored by Hauppauge, Long Island-based Spellman HV Electronics, a leader in high voltage technology in the medical, industrial and scientific fields.
