There was this huge bang and the entire glass apparatus I was using completely disintegrated into a million pieces. There were tiny bits of glass everywhere. Sulphuric acid too! Fortunately neither of those went into my eyes. Those were the days! I remember it was back to my high school years, fooling around with chemicals […]Read more "ESPcat – DIY Galvanizing – A Huge Bang"
On Battery Day, Elon Musk promised to deliver a new, bigger cylindrical battery called the 4680. Elon promised that his new cell would deliver 5 times the energy of the existing 2170 cells. We know that Musk makes a lot of big promises that are often a bit late arriving but this promise is big […]Read more "ESPcat – 4680 Big Battery Promises"
Ignoranus (a person who is both stupid and an asshole). (1) It seems that about 4% of the nurses in some of New Zealand’s District Health Boards, are giving up their jobs rather than accepting a vaccination for Covid-19. Something close to 1% of NZ school teachers are doing the same. Ignoranus would surely be […]Read more "ESPcat – Ignoranus or Genuine Asshole"
So what is it that has got Villi and Manili thinking? You can see just how excited they are! I know that you’re thinking that I don’t know what they are thinking but I think I do.

My previous blog post “Hydrogen Madness” generated so much controversy that I am forced to clear up a few points before someone starts a riot.(2) I must admit that I have been taken aback by these disagreements. I am used to having people hang on my every word as if it were the Gospel truth. […]Read more "ESPcat – Hydrogen Madness Part II"
When it comes to electricity, New Zealand finds itself in an enviable position compared to most of the world. NZ presently gets 79% of its electricity from renewable sources including hydro, wind and geothermal. The “enviable” part comes from the fact that New Zealand has an aluminum smelter that is scheduled to close in 2024. […]Read more "ESPcat – Hydrogen Madness"
I am in lockdown again. I can’t ride my motorcycle. I can’t go to the boat. I mowed the lawn and trimmed the hedge, neither of which were any fun at all. So I’m thinking about Global Warming; what else. Global Warming is becoming a real thing. Just look at the results of huge floods […]Read more "ESPcat – Rust & Global Cooling"
Lockdown is a bit of a shit! Yes, here we are in Level 4 Lockdown again. Only allowed out for essentials like food and exercise. I did my Saturday, 4 km run today right down the middle of the street because the cars are were completely missing. The covid plague is running wild throughout New […]Read more "ESPcat – Dancing Naked in the Moonlight"
Electric cars are truly exciting. Just look at my wife Gallagher with her BMW i3 if you want proof (Gallagher is not even a geek). The i3 uses lithium-ion batteries and they work great but within the next few years, lithium-ion batteries will be replaced with even better batteries. Stick with me and I will […]Read more "ESPcat Fast Charging Aluminium Graphene Batteries"
An existential crisis has struck the ESPcat (Electric Solar Powered Catamaran) project. I’m talking serious stuff; the kind of event that causes one to re-evaluate life’s purpose. Maybe I should never have tried to harness the power of the sun, simply to save the planet. Just look at that temperature gauge. 20 degrees C! You […]Read more "ESPcat Crisis Strikes!"
