This year's ABTA Convention (ABTA is the Association of British Travel Agents) took place in October in Las Palmas on Gran Canaria - the first time ABTA had gathered on the island.

A major theme of the convention was the issue of innovation in tourism. But environmental concerns have taken center stage in world politics and business development with greater frequency over the past few years.

In many countries, a solar heating system can provide a very high percentage of domestic hot water requirements. In many northern European countries, combined hot water and space heating systems are used to provide 15% to 25% home heating energy.

A solar heating system is composed of solar thermal collectors that move the heat to its point of usage and a reservoir or tank for heat storage.

The decision by European states to plead poverty at this weeks Climate Change summit in Brussels and try to back away from agreed limits is a cause of great concern

Due to all the recent recalls on tainted toys, Congress and the House have become so alarmed that they voted overwhelmingly to ban lead and other dangerous chemicals such as phthalets from children's toys.

The incandescent light bulb was invented in about 1802. Practical incandescent light bulbs were not invented until 1878 when tungsten was used for the filament. In many respects the technology hasn't changed much after the initial refinements. First let me explain how an incandescent light bulb works.

How Incandescent Light Bulbs Work

Electricity goes through a thin strand of material called a filament.

There are over 400 nuclear power reactors that are up and running on the planet, and believe it or not, the number is growing. The whole process of converting uranium into nuclear power is complex, but it all starts off with a mining operation to extract uranium ore. Believe it or not, uranium is not hard to find, it is actually a pretty common element, more common than gold.
