2 The word ‘freedom’

The word ‘freedom’ can have powerful emotive force, that is, the power to arouse strong emotions. Its connotations are almost exclusively positive. If you describe a group as ‘freedom fighters’ this suggests that you approve of the cause for which they are fighting; call them ‘terrorists’ and you make clear your disapproval.

5 Geothermal power plants
Energy from sources other than fossil and nuclear fuels is to a large extent free of the concerns about environmental effects and renewability that characterise those two sources. Each alternative source supplies energy continually, whether or not we use it. This unit considers one of these alternative sources, geothermal energy derived from the interior heat of the Earth, and the potential for this alternative to supplant fossil and nuclear fuel use to power social needs fast enough to avoid t

Using a Solar Still:  Juice
In this video segment from ZOOM, two cast members repeat an experiment designed to separate fresh water from a liquid solution, this time using colored sugar water in one solar still and orange juice in another. The basic still design they employ traps water vapor that is created when the Sun's heat causes water to evaporate. As the vapor cools, it condenses and trickles down to a collection container. Were they successful in their experiment this time? A final taste test reveals all. This video
