February on EngX brought another lively mix of thought‑provoking blogs, practical engineering discussions and broader reflections on how technology is shaping the world we work in. From unravelling sustainability terminology to exploring the foundations of AI, assessing the UK's cyber readiness and reflecting on the potential of hydro sites for pumped‑storage energy, the community continued to share knowledge and support one another.
Here’s a round‑up of what caught the eye this month.
Blogs worth a read
ClimateTech, CleanTech, DeepTech… what’s the difference?
Dr. Mohammad Harris tackled an issue that resonates across engineering and sustainability circles, the confusing overlap between terms like climate tech, clean tech and deep tech. Speaking from industry experience, he explained why engineers often find the language unclear and how these labels reflect different lenses on the same complex global challenges. The post breaks down each term, helping readers navigate conversations where terminology can obscure rather than illuminate.

From handwritten digits to thinking machines – exploring how AI learns
David James blog post explores the evolution of machine learning, starting with the classic handwritten‑digit recognition model. He unpacked how training and accuracy work in practice, and how “small” error rates look different depending on the stakes - paperwork scanning versus autonomous vehicles. He also highlighted upcoming events diving deeper into how large language models think, offering a bridge between AI fundamentals and the systems many of us now use daily.

The UK Cyber Reality Check 2026 – why incidents are now the norm
Hani’s detailed analysis of the UK Government’s Cyber Security Longitudinal Survey (Wave Five) laid bare a difficult truth: for most medium and large organisations, cyber incidents are now routine. While awareness is rising, action often follows only after impact, leading to reactive rather than strategic resilience. The blog also highlighted gaps in monitoring maturity and governance, raising important questions about how organisations can move from firefighting to long‑term capability building.

Discussions that sparked conversation
Hydro sites and the potential for pumped‑storage energy
A popular February discussion explored the idea of converting existing hydro sites into pumped‑storage energy schemes, capitalising on their established infrastructure and grid connections. Members weighed the benefits — such as pairing stored energy with floating solar PV or nearby wind — against practical constraints like reservoir design, water‑company considerations and the engineering realities of adding lower storage pools. The conversation reflected a thoughtful blend of innovation, pragmatism and lived experience from those familiar with UK hydro landscapes.

Static electricity: small sparks, big questions
Another active thread looked at the causes and mitigation of persistent static electricity issues. What began as a straightforward technical query quickly sparked a wider exchange, with engineers sharing practical strategies, diagnostic tips and examples from different sectors. It showed how even familiar topics can generate new insights when viewed through the lens of varied professional experience.

Hospital exhaust systems — airflow, safety and infection control
This discussion invited engineers to consider how hospital exhaust systems must balance air removal, contamination control and regulatory compliance. Members drew on experience in ventilation, building services and healthcare settings, offering a grounded discussion on what resilient, safe‑to-operate systems look like in practice.

Wrapping up February
February offered a rich blend of thoughtful blogs, technical insights and cross‑disciplinary conversation. Whether the topic was AI’s foundations, pumped‑storage potential, cybersecurity readiness or practical engineering challenges, the community continued to demonstrate what EngX does best: bringing together expertise, curiosity and a willingness to help others.
Here’s to another month of shared learning, and we look forward to seeing what discussions emerge in March.
