Amazing microwaves
By Doug & Dilys Griffiths - 13/07/2010
Why don’t you - when next you put your breakfast cereal jug of milk into your microwave oven for a quick warm-up - give a thought to the amazing abilities of microwaves? Maybe, just maybe, you’re a bit afraid of what’s going on in there? Well, you are not alone because many of the older generation don’t really make full use of their ovens.

Cleaning up the planet
Two words, ‘Global Warming’ have become very familiar to all of us. It is a popular topic in the newspapers, radio and TV. And it is well known that we have a very big problem ahead of us. All our major energy systems will have to change in order to have a cleaner planet for our children and grandchildren.
The science of 'sound'
When we listen to the world around us, we hear, but do we really understand the manner in which the sounds we hear reach us? There are so many sounds around us and it is amazing that we are able to sort out one sound from another
Reflecting on light
Picture it, an early Spring morning; the sun, just above the horizon, casts long, bright, white rays across the dew-covered grass. Can you believe your eyes when you see the jewels glinting there?

Motoring into the Future
Today motor transport consumes about 27% of the oil resources used in Britain. Costs are running higher and higher while oil wells show signs of drying up. Reducing vehicle oil consumption has become one of the biggest needs in modern times. Any loss of transport would have large impacts on both economics as well as poisonous waste - but will this mean the end of our beloved car?

That Two-faced Sun!
Over 100 years ago our good friend C.A. Parsons, of whom we wrote earlier, stated “The three basic sources of energy are the heat of the sun, tidal energy due to the moon and the heat of the earth”. All other energies are spin-offs from these three.
What is biomass?
How can we use Biomass as an important source of energy? Our science writers Dilys and Doug Griffiths explain all.
What is Solar energy?
What exactly is Solar Energy? And, more importantly, how can we harness this valuable resource? Our dynamic science duo - Dilys and Doug Griffiths - make this complex technology sound simple.
What is Geothermal Energy?
How many of us realise what a furious furnace lies below our feet? This shows up in various parts of the world with hot water springs and steam vents where energy obtained from the heat trapped within the earth’s core forces its way through to the surface of the earth in big blasts of steam, via geysers. Our science writers Dilys and Doug Griffiths explain why these are famous attractions for Tourists but perhaps more important, they are proving to be a large alternative source of energy: Geothermal Energy.
