Happy Friday - Electric Buses (lithium) Batteries
Engineers needed to resolve this persisting problem with electric public transportation batteries
The batteries for electric use a lot of lithium, the lightest metal and the lightest solid element under normal conditions.
The benefits of electric transportation are huge such as reduction of carbon emission but there is also a downside
In London, Transport for London have 3,826 hybrid buses, 1,397 battery electric buses, and 20 hydrogen fuel cell buses operating in London, as of March 2024, out of a total bus fleet of 8,776 – this is around 60% of the bus fleet.
The electric bus plugs into the electricity grid to get charged, and stores the electricity in batteries (often located on the roof). The batteries power an electric engine. Since an electric engine has fewer parts than an internal combustion engine, it requires less maintenance.
I use public transportation a lot because of its convenience and reliability to get me around, but recently I noticed since the introduction of electric public transportation, in this cold weather that the public transportation was not as reliable as it once was.
Two main reasons were highlighted
There aren’t enough charging points
The colder the temperature, the slower the reactions in the batteries needed to generate power.
This is not just a UK centric problem but experienced across the globe.
In the Euro News, in Dec 2023, according to Anna Stefanopoulou, at -12 Celsius, a parked EV can lose up to 30-40% of its range before it even starts its route.
In Science Direct, an article called “The influence of inclement weather on electric bus efficiency” by S Corbet · 2023 - Extreme cold and hot ambient temperatures have been shown to reduce the efficiency of Battery Electric Buses BEBs, as well as age their batteries.
I am aware that Transport for London have equipped bus stops to boost batteries wirelessly when the hybrid buses arrive and they are also increasing the numbe
Happy Friday from the STEM Positive Disruptor
As we have just celebrated International Day of Women and Girls in Science on 11th February and some of you may know that the United Nations Commission: CSW69 theme, "For All Women and Girls – Equality. Rights. Empowerment,"
I just want to remind us (females engineers) that you are worthy of your place in the STEM world and as Maya Angelou would say
"You may not control all the events that happen to you, but you can decide not to be reduced by them."
“Grab the world by the lapels and go out and kick ass.”

Cybersecurity
As engineers it is important for us to make ourselves relevant and meet the demands of the industry. You are needed in the Cybersecurity space.
The changing landscape of how we work and live is evolving rapidly and with all the benefits that emerging technology such as artificial intelligence, cloud storage, quantum technology and the Internet of Things (IoT) offers, there is also a downside to this.
The world is becoming highly interconnected, the threat opportunities for hackers and cybercriminals have increased rapidly. The attack surfaces the interconnected devices and networks offer present a wide range of vulnerabilities that must be protected. Not just at the individual level but within the organization and government as well.
According to Statista, “The global indicator 'Estimated Cost of Cybercrime' in the cybersecurity market was forecast to continuously increase between 2024 and 2029 by in total 6.4 trillion U.S. dollars (+69.41 percent). After the eleventh consecutive increasing year, the indicator is estimated to reach 15.63 trillion U.S. dollars and therefore a new peak in 2029. “
Also, in the recent Government Cyber Resilience report from the National Audit Office (NAO) has painted a stark picture of the UK government’s cyber resilience, identifying deep-rooted vulnerabilities in critical IT systems, widespread skills shortages, and inadequate funding structures.
The world of cybersecurity is evolving at an unprecedented pace. As digital transformation accelerates, the need for cybersecurity professionals is skyrocketing. Cyberattacks are becoming more sophisticated,
The demand for cybersecurity professionals is growing for a number of reasons:
• Increased Cyber Threats: With ransomware, phishing, and AI-driven cyberattacks becoming more common, organizations need to be more vigilant than ever.
• Data Privacy Regulations: Governments worldwide are enforcing stricter data protection r
Happy Friday - Space Industry is booming!

As an engineer, have you ever felt sometimes vulnerable and isolated because you are female, an ethnic minority and a mother, here comes Daniella Sladen who used these attributes as a positive driver to bring change in her industry.
This is another STEM Positive Disruptor: MIA conversation, with special guest, Daniella Sladen, Co-Founder and CTO Zulu Pods, company was started nearly 5 years ago and provides precision fluid delivery for the Aerospace and Defence Industry in the USA.
Danielle is a great role model and an inspiring leader
In our conversation we talked about a few things including
The importance of mentors / role models.
How as a business owner, engineer and a mother was able to implement and introduce an 18 week paid parental leave at Zulu pods
Why it is important not to be intimidated or uncomfortable to speak up because your experience maybe unique to others and help provide the right solution to a business problem
Please listen to our conversation in full

Are we ready for the disruption AI is bringing to our doorstep?
Governments across the world such as in the UK, China and US are investing heavily in AI infrastructure and want to become one of the AI superpowers in the world by 2030.
Davos 2025: The World Economic Forum’s annual meeting being held at the Promenade in Davos, Switzerland. AI is a hot topic. They say progress in artificial intelligence is advancing at a rapid pace, according to LinkedIn, AI will push 70% of job skills to change by 2030 but regulators are struggling to keep up and opting for a lighter touch – thereby leaving the risks and collateral damage of AI unchecked.
The Pope warns Davos summit that AI could worsen ‘crisis of truth’
Have we opened a Pandora's box where AI is concerned while it is creating new opportunities and we are already enjoying the benefits and there is more to come, are we at the same time ignoring the ugly side of AI and hope it will all go away?
In 2024, Bill Gates said his first concern is "that bad people with bad intent will use AIs for cybercrime, bioterrorism, nation-state wars." "In that case you think, okay, let's make sure the good guys have an AI that can play defence against those things, and that makes you want to move ahead and not fall behind," he said.
So, engineers as creative problem solvers, we have an opportunity to innovate, provide solutions that can identify and potentially deal with the unforeseen situations that could create risk now and in the future.
