20th january 2010 - Mission to beam electricity straight from the sun.


On the left: Part of the solar energy is lost in its way through the atmosphere by the effects of reflection and absorption.

On the right: Space-based solar power systems are an attempt to convert in space, outside the atmosphere, to avoid these losses.

 Now we know that solar power relies on energy that filters down from the sun - but imagine how much energy you could collect if you went straight to the sun itself.

Well Europe's biggest space company wants to do just that. They want to send a satellite system into space, where it would collect the Sun's energy and transmit it back to Earth where it could be used as electricity.

It's been talked about for years - but now the company planning the mission reckon they can make it happen.

Tens of thousands dead in Haiti earthquake.

Tens of thousands of people are believed to have died in Haiti following the massive earthquake on Tuesday. The most urgent need now is to get to the people who are trapped in the rubble. It is absolutely crucial that they get more emergency teams to the site immediately.

 Some emergency teams are already on the ground, some of them have heavy lifting equipment but a lot more is needed.
The survivors also need lots of help. Many people - including children - have spent a second night on the streets after the worst quake in 200 years devastated people's homes, school, hospitals and businesses.

There is no hospitals, no electricity, nothing - no food, no water, nothing. There are too many people dying.
 Damaged communication lines are making it very difficult to get through.The earthquake had a magnitude of seven on the earthquake measurement scale. The reason it had a particularly deadly impact is because it struck just ten kilometres below the Earth's surface. This meant the ground shook with enormous force. And because Haiti has many poorly built buildings - the impact has left large parts of the island in ruins. Haiti is not a rich country and they've already suffered damage from hurricanes and floods in the last year - so the massive rescue effort will need a lot of help from other countries.
