(Lars Hylander) Recent development in the electric and electronic fields, e.g. remote control of dam gates and turbines, has spurred a renewed interest in electricity generation in small rivers. But is it preferable from other aspects such as the Swedish environmental objectives and the EU water framework directive. And why are the amateur fishermen so negative to hydropower? How to reduce the heating costs in a socially responsible way (Lars Hylander) Due to large heating costs, a homeowners' association (HOA) is Uppsala is planning to replace their connection to the district heating system with a water-water heat pump. The sales representative of the heat pump demonstrates the economic advantages, but is this a good alternative for the society, considering that the district heating plant is fired by "useless" household waste, while the electricity powering the heat pump is the energy form with highest quality available, and has a multitude of alternative uses. Can a solar panel heater be accepted on a cultural heritage building (Lars Hylander) Old houses are often poorly insulated. Putting modern insulation material is generally not permitted on protected buildings such as churches, open air museum etc. Are there any other options to heat up old buildings with less stress on the environment or should the visitors be asked to bring extra clothes? Where to step off the train when heading for Gamla Uppsala (Lars Hylander) The present single railway line passing Gamla Uppsala will be replaced with a double line railway laid down in a tunnel. But where to put the station. Visitors to Gamla Uppsala burial mounds want it beside the mounds. Can the Swedish National Heritage Board accept roller escalators beside the mounds? Is the municipality rather planning for connections to a civil airport, when they suggest the station to be located several kilometers away? Could bleating sheep replace the noisy gas trimmers at Uppsala burial mounds (Lars Hylander) Motorized cutting equipment and lawn movers are emitting carbon dioxide, labor intense and noisy. Could other options be used to cut the grass. And get additional values? Or is it maybe not necessary to cut the grass twice a week? Could ancient technology reduce the nutrient loss to the Baltic Sea (Lars Hylander) The Baltic Sea has a record as a highly polluted sea with related problems such as eutrophication and algae blooms. Agricultural runoff is not the largest but still a significant source of nutrients to the Baltic Sea. Could Terra Preta, a farming practice invented to prevent nutrient leakage from Amazonian soils, be a way to reduce the leakage to the Baltic? And at the same time sequester carbon in the soil for thousands of years. Could ruralisation be a way to make cities sustainable (Lars Hylander) When Uppsala expands, most people want to build houses eastwards of the center. However, there is no proper water and sanitation systems there, so the municipality plans to dig down pipes for water, sewage and district heating. Is this sustainable, or would it be a better conservation of resources to build low energy houses with small-scale waste water treatment and water reuse. Would this be socially accepted? And would the municipality accept to give up their monopoly on sewage and waste?
