A device for safely re-directing carbon monoxide exhaust from generators includes a base, a holding mechanism, at least one support, and an exhaust tube. The base is configured to be positioned on a grounding surface. The holding mechanism is suspended at an elevated height from the base. The at least one support is connected between the base and the holding mechanism. The at least one support is configured to support the holding mechanism at the elevated height in a vertical orientation. The exhaust tube is configured to be connected to an exhaust outlet of the generator on a first end. The exhaust tube is configured to extend from the exhaust outlet of the generator vertically through the holding mechanism to a safe exhaust height above the exhaust outlet of the generator.

An apparatus includes a heat exchange member at least partially defining a passageway, and structure defining a first plurality of holes and a second plurality of holes. The first and second pluralities of holes provide fluid communication from the passageway to the exterior of the apparatus, i.e., to the atmosphere. A blower is operatively connected to the heat exchange member and configured to blow air into the passageway. The apparatus is configured such that, when the heat exchange member is sufficiently positioned with respect to a campfire, air exiting the first plurality of holes is directed downward and away from the campfire and air exiting the second plurality of holes has an upward velocity component.

An example mobile kiln system includes a mobile platform. A frame is mounted to the mobile platform. At least one kiln is rotatably mounted to the frame. The kiln is movable between a first operational position for loading a feed material into the at least one kiln, and a second operational position for unloading a biochar product from the at least one kiln following processing of the feed material. In an example, the mobile kiln system includes at least one stack assembly for the kiln. The stack assembly has a lid to cover the kiln to retain heat and a chimney to release emissions from the kiln during processing of the feed material.

Embodiments are described for a portable range hood system. The portable range hood system can include a replaceable filter and is not connected to a duct. Alternatively, the portable range hood system can be coupled to a duct. The range hood system includes a support frame structure with wheels to make the system portable and capable of being moved to any desired spot. The range hood system includes an exhaust fan and range hood, as well as a filter container housing a filter to filter out any steam, heat, odors, and smoke, including cigarette smoke. The portable range hood system can include a lighting system and plantar box for planting plants, herbs, flowers, or anything that can grow. The portable range hood system can be moved to any location in one's home or business to filter out contaminants and cleanse the surrounding air.
