Our community also includes professionals from diverse fields such as product design, physics, electrical and electronics engineering, BI, and more.
Who are we?
We are a unique community of engineers and data professionals - young graduates at the start of their careers alongside seasoned experts with extensive industry experience.
We all share a common goal: to join forces and provide precise, applicable, and knowledge-based solutions to complex environmental challenges.
The organization acts as a bridge between the broad and diverse knowledge of its members and organizations, nonprofits, and institutions facing environmental challenges that currently lack solutions - challenges that demand innovative, at times groundbreaking thinking, and multidisciplinary collaboration.
Whether we identify the need ourselves or whether approached directly from the field, our path begins with identifying the core challenge, continues with assembling a dedicated team of volunteers, and leads to developing solutions that create real impact.

Ongoing Projects
Environmental projects based on scientific research, requiring engineering support, are currently in progress.
“Use this space to share reviews from customers about the products or services offered.”
Collaboration with Israel Marine Mammal Research & Assistance Center (IMMRAC)
Development of a mechanical solution that will serve as a replacement for the lazy line safety rope, enabling the reuse of trawl fleet equipment in the event of a malfunction, while preventing entanglement and dolphin mortality caused by the lazy line in trawl operations.
Collaboration with the Sharks in Israel NGO
Creation of a well-maintained citizen science, volunteer-based database of shark and ray sightings in the Mediterranean and Red Sea, alongside the development of an interactive game that advances the identification of individuals and raises public awareness of these species.
