The present disclosure relates to a carbon dioxide capture device comprising a first reactor and a second reactor both of which show a (photo)anode containing or connected to oxygen evolution and/or carbon dioxide evolution catalyst(s) and a (photo)cathode containing or connected to an oxygen reduction catalyst, wherein the first reactor comprises an anion exchange membrane placed between the porous (photo)anode and porous (photo)cathode, and the second reactor comprises a proton exchange membrane placed between the porous (photo)anode and porous (photo)cathode. On the porous (photo)cathode side of the first reactor there is a fluid inlet able to carry carbon dioxide, air and water, and on the side of the porous (photo)cathode of the second reactor there is a fluid outlet able to carry carbon dioxide and water.

Provided is a system for a spraying booth, including a spraying booth and at least one filter with at least one VOC detector, the system further including a central database where at least data of the VOC detector are stored, whereby is achieved that the value of the measurements can be accessed and controlled centrally, either by the customer's own technicians or by the supplier's technicians, by a communication unit.

A vehicle provided with a rechargeable battery, a charging port connected to a charging cable for supplying the battery with electric power of an outside power source, a CO.sub.2 recovery device for recovering CO.sub.2, a CO.sub.2 collection port connected to a collection hose for collecting CO.sub.2 from the CO.sub.2 recovery device, and a single openable lid covering both the charging port and the CO.sub.2 collection port.

A device is provided. The device includes one or more of a container, filtration media, and a vacuum apparatus. The container includes a first hole in a first end of the container and a second hole in a second end of the container opposite the first end. The filtration media is disposed within the container, and is configured to absorb an odor present in inlet air. The vacuum apparatus is coupled to the first hole, and is configured to pull inlet air through the filtration media from the second hole and provide filtered air to the first hole.

An air filter assembly for a bicycle is disclosed. The air filter assembly includes a body having a bracket and a frame. The bracket is configured to mount to a bicycle frame. The frame defines a tapered opening having a windward side and a leeward side. The tapered opening is larger on the windward side than on the leeward side. A removable air filter cartridge is mounted within the opening of the frame such that a force acting on the air filter cartridge on the windward side tends to wedge the air filter cartridge in the opening. A foam member is attached to an outer periphery of the air filter cartridge and is disposed between the air filter cartridge and the frame. The foam member is compressible so as to hold the air filter cartridge in the opening of the frame. The foam member compresses to a greater degree on the leeward side of the opening than on the windward side of the opening. The air filter assembly is mountable to a handle bar of a bicycle.

A vehicle provided with a rechargeable battery, a charging port connected to a charging cable for supplying the battery with electric power of an outside power source, a CO.sub.2 recovery device for recovering CO.sub.2, a CO.sub.2 collection port connected to a collection hose for collecting CO.sub.2 from the CO.sub.2 recovery device, and a single openable lid covering both the charging port and the CO.sub.2 collection port.

A self-power air refresher system includes an air refresher apparatus and a plant microbial fuel cell (PMFC). The air refresher apparatus includes a fan, a filter located on an air-outlet path of the fan, and an energy storage device connected to the fan. The PMFC is disposed on the air-outlet path and includes soil contained in a container, a plant planted in the soil, and a first and second electrodes. The interaction between roots of the plant and microorganisms near the roots generates electrons, and the electrons are transmitted to the energy storage device through the first and second electrodes installed in the soil so as to enable the energy storage device to supply power to the fan. The air that has passed through the filter enters the soil of the PMFC, and is filtered by the plant and then discharged from the container.

A device for cleaning air, particularly outdoors, includes at least one housing (2) having at least one air inlet (3), filter means (4, 5), at least one fan (6), and at least one air outlet (8, 108, 208). The device is inexpensive and easy to use, and enables the user to remove pollutants from air at arbitrary times at arbitrary location because the device is transportable and implemented for positioning at different installation sites. The device may include transport means (11), particularly a chassis (11) having wheels (12). An arrangement may include a plurality of devices for cleaning air, and a software-based application, particularly a smartphone application, may be used for controlling the plurality of devices for cleaning air.
