Designers who helped build the city's first public recreation park run completely on renewable energy yesterday showed off their creation. Ma Wan Park, nestled on the small island between Tsing Yi and Lantau, is powered by wind and solar energy. The 18-hectare park opened on July 1, but manager Edmond Wong Kwok-leung said yesterday that more publicity was needed to attract visitors. Only 1,000-plus people have visited in the past few days, while it could cater for up to 1,000 visitors in each morning and afternoon session. Two windmills and a solar panel unit - designed in co-operation with Polytechnic University and CLP Power - produce all the energy it needs, said Yang Hongxing, the park's renewable-energy project leader. Excess electricity is sent to the utility grid for public use. The park also features demonstrations of hydropower, organic-waste power and wind energy. 'All the lights and air conditioning in the park are produced by this real-time system,' said Dr Yang, an associate professor at the university. Ma Wan Park is free to the public and combines European architecture and greenery representing nature, learning, arts and love. There are themed gardens with exotic species of medical plants and trees. Antiques and heritage items uncovered in Ma Wan are on display, including Qing and Tang dynasty kilns. Children and families can take part in holiday adventure programmes. Opening hours are 8am to noon and 1pm to 6pm. Tickets required for Saturdays, Sundays and public holidays are distributed in the Ma Wan Park counter at Pier 2. Each visitor can take a maximum of four tickets. There are no advance tickets. Transport to the park is via ferry. Only permitted vehicles are allowed to enter the park by road. Construction is divided into two phases. The first phase will be completed next year. The second phase is still in negotiation with residents who live on the proposed site.
