SOUTH AFRICA’s state-owned arms manufacturer Denel this week unveiled an anti-impotence pump for men who want to make love and not war, the Sunday Times newspaper reported. The vacuum pump produces an erection in 90% of cases and is less cumbersome than existing varieties, according to developer Irenco, the plastics division of Denel. “We do a lot of commercial production,” said Irenco’s managing director Jan Mulder. “Arms manufacturing depends on whether the politicans want to make war,” he added, explaining the company’s diversification.
