The number of road vehicles is growing unstoppable every year, as result, the big cities suffer from the increasing emission of carbon dioxide. We are planning to add a modern module on public surface transport of the cities. The main technology of the module can convert carbon dioxide to other compounds as well as generate electrical energy which could be used in a more valuable way. Our beach-market is Vilnius, the biggest city of Lithuania. There traffic jumps are a big issue, thus, while the public transport usually stops in them, they can clean the air in the urban locations where the need is the strongest one.
