A French melon-powered power plant

Do you like melons? Tasty aren't they?

Sweet when ripe, and refreshing.

You've got to be careful about storing them though because apparently their pungent pong can permeate other food and you've probably also noticed how their remains can stink out a kitchen when left in the bin.

Something to do with the amount of methane melons produce when they decompose - just like all fruit really.

The company Boyer S.A Philibon in the southwestern département of Tarn et Garonne knows all about that.

It's one of France's biggest producers and packers of melons and its processing station is in the town of Moissac.

But Boyer S.A also has a huge waste problem in the shape of rotten melons - 1,800 tonnes of them annually.

So earlier this year it called in the experts, turning to the Belgian-based company GreenWatt, a specialist in building, designing and maintaining biogas plants and the fruits (ouch) of the two companies collaboration will be unveiled on Friday.

That's when France's first biogas plant or anaerobic digester will open.

And it'll apparently be able to produce enough hot water for the whole of the Boyer S.A site as well as the equivalent of electricity for 150 homes which it'll sell back to the country's largest utility company Électricité de France.

Not bad going for a load of mouldy fruit, and very green to boot.

So forget nuclear, coal, hydro-electric, thermal, wind and solar power.

The future is melon - well at least as far as Boyer S.A is concerned.

Heatwave alert in France

It's hot in France at the moment - very hot.

and the country's meteorological service, Météo France, has put several regions on heatwave alert for the next couple of days. Daytime highs are forecast to peak at 37 degrees Celsius in some parts of the country and not dip below 20 degrees at night.

The heatwave is not predicted to be nearly as long or as fatal as the one that hit much of continental Europe in 2003 and during which around 15,000 (mainly elderly) people died in France.

But the health minister, Roselyne Bachelot, is not taking any chances and has advised local authorities to "be on their guard".

"The lessons of 2003 have been learned," she said on national radio Friday morning.

"Départements are ready and health facilities have been prepared. The number of hospital beds available is higher than normal at this time of year and mayors throughout the country have maintained lists to pinpoint those most at risk."

The eastern region of Alsace is expected to be one of the hottest places with temperatures in the main city of Strasbourg rising as high as 37 degrees Celsius.

The Prefect of the region, Pierre-Etienne Bisch, has put health and emergency services on high alert.

In Paris and the surrounding départements, local authorities have introduced a "system of support and guidance" for the most vulnerable citizens.

France's second largest city, Lyon, the surrounding metropolitan area and the whole of the Rhône département is the third region of the country in which emergency services are on high alert following Météo France's heatwave warning.

The hot spell also coincides with what is the second weekend of the summer holidays and tailbacks are expected on many of the country's motorways.

While the metro in the French capital for example has become a roasting tin for commuters and tourists alike and some bosses in companies around the country have encouraged employees to stagger their working hours and come in earlier to avoid the heat, one man in the south-western town of Moissac tried another way of dealing with the hot weather.

According to the regional daily La Dépêche du Midi, the man decided to begin mowing his lawn - at 11 o'clock at night - and would have continued doing so had his neighbours not complained and called the local police.
