Some interesting thoughts about electronics and power consumption. But there is another side of electronics that is so often completely ignored or at least ignored in big parts: EMF.

There’s rightfully much ado about the climate — from extreme weather events, severe droughts and water crises to fossil fuels and the race to renewables. However, there’s far too little talk about electronics and their role in environmental ecosystems.

Some good starting point. It would be prudent to point to some other aspect of electronics, that is EMF, both by WIFI and dirty electricity, ie spikes, surges and harmonics within the electrical network.
While WIFI is already openly debated and dangers are researched, the dirty electricity phenomenon seem to be widely ignored.

In terms of WIFI, I’d like to add the point that while I am aware of the possible and likely health impacts of it, I am too comfortable to change it and discard it. However my router has a setting that allows for scheduled WIFI and the WIFI switches automatically off over night. Any WIFI devices are kept away from the bedrooms, the kids switch theirs off in the evening.

In terms of dirty electricity, there is not too much one can do other than installing filters. Tests in terms of transients and spikes back into the grid are hardly controlled by regulations and not tested. Fact is you CAN test it and find out retrospectively which device is good or worse.

And in terms of EMF emitted from devices, it would appear that regulations are far too liberal. Most LED and CFL’s are terrible, and so are many power supplies, ie transformers for our lovely gadgets. The one for my laptop is a massive emitter of EMF hence I keep it well away from me.

Rule of thumb: Switch off whatever you do not need, including bluetooth, wifi and transformers.

Pieces of salada crisp bread, broken up and stacked up


I have been a scout leader for more than a decade now and one of the things we learnt and what we try and teach the kids is SALADA. This is an acronym for “Stop Assess Listen Allocate Do Assess again”. It is also symbolised by a piece of the brand salada crisp bread that you try and stuff into your mouth in one big piece – which does hardly work – without pain that is. So the lesson from this is also that you need to break it down into chunks to eat it. Just like you have to break down your task into manageable chunks to do them. This aligns with the “Allocate” in SALADA, ie break it up and give your team members jobs.

COP26 – Just another talk? Up to you!

It’s that time of the year again – ground hog day – another global leader meeting to tackle climate change. Or to talk about tackling climate change.
Do whatever you can – at home or work, in your job, in your projects.
It’s up to you, not anyone else.

Horrible Hybrids – A reminder

Michael Braungart and William McDonough called them “horrible hybrids” in their 2002 book “Crade to Cradle”. Things that are fused together from different materials that cannot be separated and thus not recycled.

Soybeans in a supermarket in China

What to eat those days?

Being married to a vegetarian and not cooking extra at home, the family tend to eat vegetarian – with lots of soy products. So this post is more of a collection of thoughts around soy products. And yet again there’s confusing information out there. The general perception is that soy is good for you: Non-animal, vegan, high in protein, etc.

But then you do a bit of research and googling and find quite contradicting information as well.

Kiwibuilds 100,000 homes progress

The average build numbers according to my article published in 2018 would have been ~30,000 homes by now. The actual stats are somewhat lower than that: 934 – yes: 934. Even if we would say that starting up is hard and the initial output would have been lower, would we maybe not have expected 20,000 homes? But we got 934.
