Freezing toilet

Last updated

Freezing toilet is a kind of dry toilet powered by electricity which freezes the content in a short time. [1] Freezing toilets work by electricity, as they are plugged into the wall. They do not need water, pipes, ventilation or chemicals to work. The function of freezing toilets is based on freezing. The contents freeze in a short time stopping bacteria from growing and keeping it odourless. Consequently, it does not need mixtures or other chemicals. [2]

Freezing toilets can be moved, as they only need a plug to work. The machine consumes about 40 watts of electricity.[ citation needed ]

Freezing toilets were developed in Sweden in the 1970s, but now production is in Finland. [3] [4]

Examples

This kind of toilet is installed at the Mirrorcube treeroom at Treehotel (Harads, Sweden). [5]

A hydrogen vehicle is a vehicle that uses hydrogen to move it. Hydrogen vehicles include some road vehicles, rail vehicles, space rockets, forklifts, ships and aircraft. Motive power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by hydrogen internal combustion.

Greywater refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets. Sources of greywater include sinks, showers, baths, washing machines or dishwashers. As greywater contains fewer pathogens than blackwater, it is generally safer to handle and easier to treat and reuse onsite for toilet flushing, landscape or crop irrigation, and other non-potable uses. Greywater may still have some pathogen content from laundering soiled clothing or cleaning the anal area in the shower or bath.

An electric vehicle (EV) is a vehicle that uses one or more electric motors for propulsion. The vehicle can be powered by a collector system, with electricity from extravehicular sources, or can be powered autonomously by a battery or by converting fuel to electricity using a generator or fuel cells. EVs include road and rail vehicles, electric boats and underwater vessels, electric aircraft and electric spacecraft.

An alternative fuel vehicle is a motor vehicle that runs on alternative fuel rather than traditional petroleum fuels. The term also refers to any technology powering an engine that does not solely involve petroleum. Because of a combination of factors, such as environmental and health concerns including climate change and air pollution, high oil-prices and the potential for peak oil, development of cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world.

The electricity sector in Finland relies on nuclear power, renewable energy, cogeneration and electricity import from neighboring countries. Finland has the highest per-capita electricity consumption in the EU. Co-generation of heat and electricity for industry process heat and district heating is common. Finland is one of the last countries in the world still burning peat.

<span class="mw-page-title-main">Energy in Sweden</span> Overview of energy use in Sweden

Energy in Sweden describes energy and electricity production, consumption and import in Sweden. Electricity sector in Sweden is the main article of electricity in Sweden. The Swedish climate bill of February 2017 aims to make Sweden carbon neutral by 2045. The Swedish target is to decline emission of climate gases 63% from 1990 to 2030 and international transportation excluding foreign flights 70%. By 2014 just over half of the country's total final energy consumption in electricity, heating and cooling and transport combined was provided by renewables, the highest share amongst the then 28 EU member countries. About a third of Sweden's electricity is generated by nuclear power. In generating a year's worth of this energy, Swedes generate about 4 tonnes of CO2 emissions each. Since 2010, sustainability measures have reduced total emissions even as the population has increased.
