Survival under the Sun (1976x6)

Air date: Dec 06, 1976

Methods in which sunshine can create electricity and fuel are investigated in this 1976 CHRISTMAS LECTURE from chemist George Porter. Harnessing the sun's energy for power using the chemical element silicon is explored. Porter demos how silicon can be used to create solar panels for satellites which run off energy from sunlight. Using a timeline as a visual aid, Porter talks about the eradication of fossil fuels and how the sun can continue to supply us with power in the future.
