Methods and systems are described herein which allow to determine an icing condition without requiring a wind speed measurement. The methods and systems use two sensing members both being exposed to conditions in an environment. The determination is made based on a capacity of the sensing members to react differently to the conditions to which they are exposed. The conditions can be environmental or controlled. The determination includes measuring a variable indicative of the thermal state of each individual sensing member, and processing the measured values to generate the signal indicative of icing condition. The icing condition can be instrumental or meteorological.

System and method for determining an icing condition status of an environment

The method includes receiving a value of a quantity of heat applied to at least a portion of a structure, said structure having a sensor surface exposed to the environment, receiving a temperature measurement of the sensor surface, receiving a wind speed measurement of the environment, receiving an ambient temperature measurement of the environment, determining a heat transfer projection of the sensor area using at least the wind speed measurement, the ambient temperature measurement, and one of the value of a quantity of heat and a target temperature of the sensor surface; comparing the heat transfer projection to an associated heat transfer value, and generating a signal indicating the icing condition status based on the comparison.

A process is disclosed for recycling carbon dioxide emissions from a fossil-fuel power plant into useful carbonated species The process primarily comprises the steps of: a) burning the fossil fuel, thereby generating heat and a hot exhaust gas containing CO; and b) converting the heat into energy. The process is characterized in that it further comprises the steps of: c) cooling the exhaust gas; and d) biologically transforming the COcontained in the cooled exhaust gas into carbonated species, thereby obtaining a low COexhaust gas and producing useful carbonated species. The low COexhaust gas obtained in step d) can be released in the atmosphere without increasing the problem of greenhouse effect.

A ventilation system is disclosed for an enclosure in which people live. The ventilation system comprises a first ducting means for ducting fresh air from outside to inside the enclosure and a second ducting means for ducting stale air. The second ducting means comprises a stale air inlet for receiving stale air containing carbon dioxide from inside the enclosure and an exhaust manifold having a first vent to exhaust air outside the enclosure and a second vent in fluid communication with the first ducting means to return clean air into the first ducting means. The ventilation system is further characterised in that it comprises catalysing means for catalysing hydration of carbon dioxide contained in at least a portion of the stale air into a solution of carbonate ions and hydrogen ions, and thereby removing carbon dioxide from said portion of the stale air and obtaining clean air. Evacuating means are also provided for evacuating the solution out of the ventilation system.

The object of the invention is the coupling of a hydrogen fuel cell to an enzymatic process for the production of electricity and the transformation and sequestration of CO. Gaseous COemissions from processes such as hydrocarbon reforming are transformed into carbonate or bicarbonate ions and hydrogen ions by the enzymatic system in order to prevent their contribution to the greenhouse effect. The hydrogen ions resulting from the enzymatic process are recovered and combined in order to supply the hydrogen fuel cell. Finally, water, a by-product of the oxidizing reaction of the hydrogen fuel cell, is recovered and recycled back into the aqueous enzymatic system.
