Elon Musk has been on a mission to revolutionise power and create a sustainable source for households across the world. Yet, so far the cost of installing a Powerwall was been too steep for everyday households (at around $3,000) and the capacity has been insufficient, with the battery only able to store up to 10 kWh of electricity, or around a third of the amount the average daily American household consumes.

But the idea of a ‘Powerwall’ has led a group of enthusiast to build their own version, using everyday materials that can be already found around the household. No billion dollar investment required, just a keen enthusiasm for engineering.

The community of ‘Powerwallers’ have taken it upon themselves to create a sustainable household energy source, and so far, they seem to be succeeding.

How do they do it?

Most of the ‘Powerwallers’ use 18650 lithium-ion batteries for their projects, which you can buy off the shelf for around £5 . The batteries are usually encased in colourful plastic coating and can be found inside electronics like laptops.

The challenge with building a Powerwall is the number of batteries required, which often involves stockpiling hundreds, if not thousands of 18650 cells needed to build a battery capable of storing a significant amount of power.

However, getting hold of lithium-ion batteries is difficult. Although contained in old laptops, the number required to build a significant power source is a major obstacle to DIY Powerwallers. Start collecting now if you want to build your power source for the future.

But you can’t help but be inspired by the effort!
