Lightning Bolts

Lightning

In 1998, lightning killed an entire football team in Congo whilst leaving the home side completely unscathed.

Although lightning may seem like a rare event in the UK, every second 100 lightning strikes hit the Earth producing as much energy per year as 75,000 megaton bombs.

This week on Material World, Quentin Cooper talks to Dr Ian Cotton, who creates lightning in his laboratory at the National Grid's High Voltage Research Centre at UMIST. And to Alex Hill, the Met Office's lightning expert.

Telecare

By the year 2010, the Department of Health aims to have telecare devices in all UK homes that need them.

They will range from personal health monitors for the chronically sick, to devices that alert social services to an elderly person in difficulty.

Professor James Barlow of Imperial College and Dr James McLaughlin of the University of Ulster join Quentin Cooper to discuss the technologies currently being developed to meet the needs of those who are chronically sick or disabled. And he asks whether telecare can ever replace a face to face medical consultation?
