The Heart of the Joule


The unstated question is, will this project, this car, subtract from the woes generated by other cars? Woes that include pollution, resource depletion (resources that could be utilised as fertilizers and medicines for generations to come) and a widening systemic collapse that threatens to disintegrate the entire auto-industry.

“In our efforts to make a positive difference, Kobus especially did a lot of research, and we came up with the idea of an electric vehicle. Then we went to the Innovation Fund – a South African Department affiliated to the Department of Science and Technology. We got seed funding for early development; it’s probably the only fund in the country where you can get funds for early development. It took us 18 months to get the money; not because they weren’t convinced of the merits of the project – it’s just a very cumbersome process. We got R5 million for the first year, which was really a feasibility study, a paper study, with a promise of R10 million to follow. While they initially requested we get additional funding from an industrial partner, they later came to believe – as we do – that this was too big to hastily involve someone else. So they gave us their full backing to nurture this project to its completion. And since 2008 the IDC have also started backing us. So the IDC and the Innovation Fund are shareholders in Optimal Energy.”

Future Shock: A World Filled With Batteries (L)


South Africans have been told to expect load shedding and power outages for the next few years, with the next winter season projected to have more blackouts than the last. I've personally experiened a number of surges and the like in suburban Johannesburg, resulting in computer failures and all the rest.

One useful resource to at least save your data during a possible power failure is a UPS: uninterrupted power supply. Basically you route all your electricity through this box - about the size of a shoebox, sometimes bigger - and when the power goes out, the charger in the your UPS kicks in and gives you a chance to shutdown your computer at your leisure. I think it gives you up to 4 hours additional computing time. But this is the sort of thing all Jozi residents should have.

In the wider context of the world - South Africa is not the only country with aging electrical infrastructure and a looming energy capacity/supply crisis - batteries are likely to make a comeback. Unfortunately, the laws of the universe once again demonstrate just what a wonderful and magical resource oil actually is. Despite great minds working on the issue, it turns out that the electrical car's batteries are not only extremely expensive, but the limits to the power storage are not easily extended. Smaller batteries like the lithium batteries in cellphones and notebooks unforunately do not extend much further, certainly not porportionally, as we expect the same sort of power (energy) output motoring through suburbia over the next era.

Jim Kunstler says it best: No combination of alternatives is going to allow us to use the highway systems and continue our easy motoring culture as we are doing now.
