How Together We Can Create the Earthing Superpowers We Need to Save Lives.

Before we get into today’s blog “Earthing Superpowers” and how together we can create the superpowers we need to save lives. I want to share a personal story.

I have a confession to make…

Earlier this year I found myself in the Southern Ocean at 45deg Lattitude barrelling along at 20-30 knots on a 70 foot (23m) surfboard otherwise known as a sailboat called Black Betty in 45kts winds and 10-12m swells. In those conditions, it’s all one can do, but to think about the here and immediate ‘now’. But, outside the times of sheer panic, and during the time of reflection, the thoughts of superpowers surfaces.

Soil Resistivity Testing Methods Part 3 The Wenner 4 Probe Test.

Soil Resistivity Testing Methods a popular post. Originally published in 2013 and now updated in 2020.

Wenner 4 Probe test is one of the most common soil resistivity testing methods. It is also part 3 in a series of short posts on Soil Resistivity Testing Methods. Part 1 & Part 3. Together with, the common mistakes encountered. And also, practical advice on how to avoid the Soil Resistivity Testing 10 Common Mistakes.

Soil Resistivity Testing Methods – The Wenner 4 Probe

So soil resistivity testing can be carried out using different methods. Therefore, below describes the Wenner 4 Probe Test Method. Also, its one of the three most popular soil resistivity methods employed, to perform a soil resistivity test:

Not Only Earthing Studies. Other things you never realised YOU could do!

We’ve written previously about why we use CDEGS HIFREQ and (X)GSA_FD for earthing studies. Also, the reasons to invest in the top 1% of tools, knowledge and consultants. But once you’ve invested in building the model to understand what earthing is required, what are the other things you can do with this model. Additionally, answer other questions you might have?

Seasonal Greetings and A Round-Up of 2019

Firstly I’d like to take this opportunity to wish our Clients, Friends, Academy Students and Blog subscribers SEASONAL GREETINGS and a very prosperous New Year.

I’m actually in Western Australia writing this post. Having completed a life long ambition and the most challenging personal goal of my life. That’s crossing the Southern Ocean from South Africa to Australia. Competing in a leg of the Clipper Round the World Yacht Race. I write more about this in my personal blog.

Comparison between XGSLab and CDEGS

In this blog, I’m going under to hood, so to speak. Comparing CDEGS with XGSLab to show you some real-world examples where CDEGS and XGSLab give almost identical results.

Therefore, in all of these examples, we have completed and verified the earthing design for these sites and found good agreement between the modelled results and the post-installation measurements. On this basis, we can say that XGSLab matches CDEGS for accuracy, and both tools have good agreement with the real-world measurements.
