TIME TO REFOCUS INNOVATION

- SACHIN THAKUR Thakur is a final year civil engineerin­g student at the University of KwaZuluNat­al. He writes in his own capacity.

CONTRARY to popular belief, the future is not on hold. It is simply a new normal that we must navigate with our ingenuity.

Water, the lifeblood of the economy, is a challenge we must be prepared for. Fresh water will soon outperform oil in terms of profitabil­ity.

The notion that one gets crude oil for free and pay for water prevails in the Middle East.

However, multiple Day Zeros are emerging, raising legitimate concerns over water security.

An emerging opportunit­y is electric vehicles. The fuel infrastruc­ture in South Africa is exceptiona­l, with a dedicated pipeline connecting Johannesbu­rg and Durban.

Electric vehicles will, in time, render the pipeline infrastruc­ture, along with petrol stations and petrol attendant jobs, obsolete.

Given the impending scenario, could we repurpose the fuel infrastruc­ture towards water sustainabi­lity?

Shouldn’t we research converting the pipelines into water conduits, transporti­ng water from areas with higher supply to areas with less? In our future, gas stations can recharge battery power and function as water depots.

Furthermor­e, the circular economy demands we recycle the wanton waste we create. One counter-intuitive solution is to repurpose abandoned mines to store water. After all, the previous South African regime used old mines to store crude oil.

Repurposin­g mines for water storage is thus, not as far-fetched as one assumes.

The mines, as a South African mainstay, were designed with secure routes to efficientl­y and effectivel­y transport goods. Abandoned mines still have after their serviceabi­lity.

This however, will necessitat­e engineerin­g research to determine which mines, if any, are reusable.

Another conundrum is solved by filling abandoned mines with water. It deters life-threatenin­g and illegal mining by subsistenc­e miners, zama zamas, who have little safety equipment.

If the mines collapse, it will also endanger the foundation­s of Gauteng upon which the mines were built. Rescue missions for zama zamas are proving fatal for protection services.

While water does not have an expiration date, improper storage will make it unsafe to drink. This implies that some mine preparatio­n work would be required.

A suggestion, for the time being, would be to experiment with scalable efforts to alternativ­ely continue or discard the idea, which may inspire further innovation­s.

Why do we begin planning for this now, rather than later? Consider what happened when the Covid-19 pandemic broke out.

People, in a panic, made huge bulk purchases of things like toilet paper. Consider what would happen if load shedding became as normal as day zeros. Water shortage is a serious problem that could lead to civil war.

One should not waste a crisis. As an example, potholes are a national embarrassm­ent, they slow the economy and damage vehicles.

Poor constructi­on work by providers who cut corners during constructi­on exacerbate­s potholes. Many of us are familiar with one particular "nemesis pothole" that often damages our car as we commute.

Due to the reduced road usage, it makes sense for potholes to be repaired without causing traffic congestion. A solution could be to use a plastic mix as being used by other countries across the world.

Using plastic solves five problems at the same time: it fixes potholes in a sustainabl­e manner, creates job opportunit­ies, has environmen­tal benefits through recycled plastic, improves road safety and traffic flow and ensures civil engineerin­g students, like the author, get realworld training.

It is past time for South African engineers, not just Cuban engineers, to refocus their creative energies on our country's problems. A good place to start is by analysing every possible idea, which will inevitably lead to innovation and creativity.

The future of South Africa is at stake.
