Some cars get you from A to B. Some do a whole lot more. The newKUGA has a 2.5l Duratec turbo
engine (147kW, 320Nm), intelligent all-wheel drive, a clever split tailgate and a full suite of life-
enhancing technology features. It won’t just complement your life, the new KUGA will improve it.

Contrary to widespread belief,
South Africa does not lurk atthe bottom end of the techno-
logical food chain. In fact, whenit comes to connecting with the
future through new technologiesand exploiting every avenue ofcommunication, our hunger
knows no bounds – as does ourpride in home-grown innovation.
Now say hello to FutureTech
2012, a unique POPULAR MECHANICS initiative that will bring together
tech-savvy people from all overSouth Africa for an exciting and
inspiring conference. It happens
in Johannesburg on 25 October,and it’s destined to be a “must”
on the calendar of anyone who
wants to get up to speed in aworld ruled by technology. Thetheme of our inaugural confer-
ence is “connect”, a word that
will resonate with anyone whounderstands the mechanics of
the 21st century.Representing the top echelon
of science and technology, our
presenters will unpack techno-logies that are already changing
our lives for the better, enablingus to share world-changing ideas
and solve challenges together.
Programme details and bookinginformation will be available
soon; please watch for announce-ments via our Web site, our
weekly e-mail newsletters (“The
Cutting Edge”) our TV commer-cials and other channels.
There’s also some good newsfor South Africa’s vibrant invent-
ing community: our Inventor ofthe Year Competition remains as
an integral part of the FutureTech
initiative. Details of the annualchallenge, which offers even big-
ger cash prizes for 2012, will bereleased within the next few
weeks (see elsewhere in this issue).
Now to this month’s magazine.Our cover story, “Re-engineer-
ing the human”, explores someremarkable breakthroughs in
the design of prosthetic limbs,
artificial organs, bones andeven blood cells. Bionic limbs
with machine intelligence cannow sense their environment
and predict a user’s intentions.
The prosthetic arm on our coveris actually composed of a swarm

of robots, each detachable seg-
ment housing a processor thatworks in concert with the others.
Wonderful stuff, and it’s bring-
ing new hope to many people.We hope you enjoy our bumper
32-page Tech Focus supplement,which comes free with this
month’s issue. It introduces fas-
cinating and increasingly relevanttechnologies in the fields of home
entertainment, automotive safety,
leisure pursuits, communications,and much more. We provide ad-vice on buying a new TV, intro-
duce a couple of outrageous
bicycles, unpack appliances withbrains, and ask what it will take
for tablets to replace PCs.As always, we showcase a
heady assortment of new gadgets
throughout the magazine – whichbrings me to an opportunity for
full disclosure. Having been con-sumed with guilt for the past
few weeks, I should now confess
to my wife (who is morallyobliged to read PM every month)
that the 600 mW laser pointer,Music Angel docking station,
multi-bladed camping knife and
Samurai steel LED watch werenot, in fact, “for the office”.
Finally, regular PM readerswho may have been alarmed by
our “haunted house” headlineneed not be concerned: it’s not
about exorcism or exploring
beyond the veil. Instead, weexplain what makes doors bang
and floors creak in your ageinghouse, then tell how you to fix
them. It’s what we do.

LET’S BRI NG THE MBACK
I was interested to see the poll results in your
issue of March 2012 indicating that 25 per cent ofyour readers believe scientists should not resurrect
the woolly mammoth because they “went extinct10 000 years ago for a reason”, and because “it is not
up to us to play creator”.What these readers have not taken into account is research, published in
the same month, indicating that woolly mammoths would probably not have
been extinct in the first place were it not for people. Our forebears played asmuch a role in the end of that species as Nature.
Graham Prescott and David Williams, zoologists from the University of
Cambridge, developed a model to calculate how climate change and the arrivalof humans respectively correlated to the disappearance of species of megafauna.They found it very likely that Stone Age hunters had a hand in at least some
of these extinctions.Not only the woolly mammoth seems to have been our victim, but possibly
also giant kangaroos and some big flightless birds. The findings, published inProceedings of the National Academy of Sciences, are a poignant reminder of
how destructive our species has been since its early days. If we can undo some
of that harm, why not?JOHANNES BERTUS DE VILLIERS

Think big, people
It’s time for a big South African companyto reach into its deep pockets (call it amarketing strategy, if you like) and pull out
a plan to galvanise our country’s legions ofinventors and innovators. POPULAR MECHANICS
has laid some wonderful groundwork withits Inventors Conferences and competitions,
but now it’s the turn of the Big Players.
My advice: take your cue from theX Prize Foundation (www.xprize.org).
These guys have big ideas, and set seriouschallenges – and it works. A few months
ago, they launched the Tricorder X Prize,sponsored by Qualcomm – an R80 million
bonanza to be awarded for creating amobile device that can “diagnose patients
better than or equal to a panel of boardcertified physicians”. They have also part-
nered with the Bill & Melinda Gates Foun-dation to develop a prize for a better
tuberculosis diagnostic tool.
Getting the idea? We need a R10 millionprize for someone who develops a basic
but durable house costing no more thanR1 000, or a device that halves infant mor-
tality in impoverished areas, or a foolproofdetector of political venality. Who’s doing
the brainstorming?
CRAIG ABBOTTOBSERVATORYEditor’s note: Excellent idea. In the mean-
time, we’re about to release details of our
second annual Inventors Competition,
which carries even bigger cash prizes this
year, and we’re working on an exciting
conference that promises to light a fire
among “connected” South Africans.
Timeless hints dept As you point out in “Editor’s notes”,it’s amazing how many of the tips from
old issues of PM still hold good today(“100 years of top tips”, April issue). For
example, my wife still uses half a potato
to moisten the adhesive on envelopes thatwe mail to our clients (if you haven’t licked
an envelope for a while, believe me whenI say the taste is awful). Another hint that
sounded familiar was the one about addingsand to floor paint to create a non-slip sur-
face. Since an elderly relative slipped andfell on our wet front porch last winter, we’ve
coated all potentially hazardous floorswith non-slip paint. It works beautifully.

Of course,the pipes don’t last as long as copper, butat least they are cheap to replace.

Anyway, the parachute’s real diameter is
165 feet, or about 50 metres. Thanks for

You’re welcome, dudeI cannot begin to tell you how much Ienjoyed the April issue of POPULAR MECHANICS,
having been an avid fan ever since seeingit for the first time on a railway stationbookshelf when I was 11 years old, wayback in 1943. Memories came floodingback of the many innovative ideas foundin PM in years gone by. Thank you forreawakening those memories.
I especially enjoy the projects that areonce again appearing for the do-it-your-self readers. Thanks for the wonderfulwork you and your staff do in bringing usour own South African POPULAR MECHANICS.
P.S. I am the “dude” who designed andbuilt the workbench that you featured in

Questions, questionsYour article on Waldo Stakes and his Sonic Wind car (“The 3 000 km/h obsession”,January issue) refers. Here are some aspects that bother me:
l Wing Commander Andy Green was in South Africa late last year on a lecture tour;Thrust SSC smashed the sound barrier in 1997; Bloodhound (another potential record-breaker) is to go beyond that.l A wind tunnel cannot be used for testing the model of a supersonic car as there is
no “ground effect”.l Where does the money come from? Waldo “moonlights as a rocket scientist” but
he has no qualifications. Who employs him?l Where is the planned test ground? Bloodhound will come to Hakskeen Pan in the
Northern Cape. The track will be 20 km long – for 1 600 km/h. How long for 3 000 km/h?
l Is it so wrong to chase a dream beyond one’s grasp? Maybe not, but, in this case,it may prove to be fatally foolish. Are there no restraints in the US regarding people
wanting to exit this world in a spectacular fashion?But I marvel at all this. As a young lad, back in the Fifties, I was fascinated by speed
and the sound barrier. I sketched my hero, Sir Malcolm Campbell, and imagined himbreaking the sound barrier in Bluebird. I have also lived to see some of the sciencefiction of Dan Dare (Eagle comics) become reality. Good luck, Waldo!
