This is good idea to make use of roof top space to grow vegetables. The scheme called Food from the Sky has planted this vegetable garden on top of the roof of Budgens in Crouch End. The garden was actually started last May and is now producing enough vegetables to sell in the supermarket each Friday. The garden uses food waste from the supermarket to make compost and grows a variety of produce including potatoes, peas, broccoli, strawberries and raspberries. The warmth from the supermarkets heating and lighting systems apparently creates the perfect conditions for the plants because it helps to protect them from the worst of the frosts. The rooftop garden also has the advantage of being free from slugs and snails. It certainly is a good idea and a clever use of space, as the scheme expands hopefully we will see more of these gardens and perhaps one might soon come to a supermarket near you.

This is an interesting idea, its a way of turning urine into hydrogen fuel. The idea comes from Gerardine Botte, a professor of chemical and biomolecular engineering at Ohio University. She worked on the fact that urine contains two compounds that can be a source of hydrogen, ammonia and urea. By placing an electrode in wastewater and applying a gentle current she then found that hydrogen gas can be used to power a fuel cell. Her system works in the same way as the electrolysis of water but ammonia and urea hold their hydrogen atoms less tightly than water meaning less energy is required to split them off. The technology would be put to the best use in areas where there are large numbers of people such as airports and sports stadiums with an office building of 200 to 300 workers having the potential to generate 2 kilowatts of power, It could also be used to generate power from animals with the urine produced by 1,000 cows generating around 40 to 50 kilowatts of power. It’s certainly an interesting idea particularly as it make use of a waste product.

In an interesting experiment scientists tagged wild baby turtles like this one to see how far they swim. The surprising results found that the turtles travel around 4,500 miles despite the fact that they are only six months old. The turtles were tagged with customised 9 gram tags and were monitored by satellite as they made their journey. To put the distance they travel into context it is like travelling from London to Mumbai. Amazing for such little creatures.

According to this article the Harvester chain of restaurants will be the first national chain to put the calorie content on its menus. The chain will print the calorie content of every dish from a light tomato soup at 90 calories to a rather calorific mixed grill at 910 calories. Research carried out by Harvester found that customers would find the information useful rather than taking the enjoyment out of having a meal out. Although the government has called on restaurants to display information on calorie content, it is currently voluntary and as yet Harvester is in the minority in publishing the information. It will be interesting to see whether other large restaurant chains start to follow suit.

This is interesting it’s a device called the Solowheel. It’s like a unicycle and is being hailed as the latest device for commuter's. The user puts their feet on the foldable platforms on either side of the wheel and leans forward to move, back to stop and left or right to turn. It has a top speed of 12 mph and can travel for two hours on a 45 minute charge. The rechargeable battery also recaptures energy when it’s going downhill or slowing down. It certainly looks interesting but with a £975 price tag it’s a little pricy.

This is one of the first pictures of an elusive Sunda clouded leopard. The cat was only discovered four years ago but up to now has proved difficult to photograph. The leopard is unusual because it has adapted to living in tree tops. It uses its long tail to balance on branches and its claws to climb tall trees.

This is an interesting idea it’s the smell of the countryside in a tin. Designed for country people who have moved to the city the product “Countryside air to go” has become quite popular. The air is sucked out of an ageing wooden stable filled with gas producing cattle and packaged in a can. The can costs £5 and can be ordered from www.stallduft.de if you want one.

If you are constantly stopping your cat from clawing your furniture then you may not be surprised to find pets are responsible for around £690 of damage per year. That’s according to confused.com who say pets are responsible for some £3.3bn of damage in the UK every year. Many pet owners do no know whether their home insurance policy covers them for pet damage although a third of people would add this option if it were available on their insurance. According to the article none of the major insurance providers cover accidental damage caused by pets although some feel that there should be insurance tailor made for pet owners. We have got used to protecting our nice sofa with throws to prevent them being scratched and finding strong household cleaners for cat sick stain on the carpet. I don’t think, however, that I would expect my household insurance to cover any damage my cats create. After all, it is my choice to have pets so if they destroy my house I guess it’s my own fault.
