Japan is taking the lead in developing hi-tech products that protect the planet as a recent exhibition in Tokyo showed. Thousands of environmentally friendly products were on display at the Eco-Products exhibition, which attracted over 100,000 visitors. Japan has a lot to teach the rest of the world when it comes to being green and that is precisely what the exhibitors at Eco-Products had in mind. One of the biggest draws at the show was Toyota's fuel-cell car. Four of the clean vehicles have just been leased by the Japanese Government to improve its green credentials. However, it could be some time before they become a common sight on the roads as the cost of leasing them is a hefty £6,315 per month. http://news.bbc.co.uk/1/hi/technology/2569297.stm
