The TecEco Tec-Kiln
The Tec-Kiln was originally designed for low temperature (<750ºC) calcination of magnesium carbonate to produce reactive magnesia[1] for use in TecEco Cements without releases and will be used in Gaia Engineering which is a process that contemplates obtaining the magnesium carbonates required from sea water. The Tec-Kiln can also be used to produce reactive magnesia from other sources of ore such as mined magnesite.
To reverse the environmentally damaging impact of molecular flows from techno-processes such as too much CO2 in the air, the TecEco Tec-Kiln will use non fossil fuel energy such as solar or solar derived energy (e.g. wind or wave energy) for producing the magnesia required for TecEco cements. It is unique in that it operates in a closed system whereby the waste energy from grinding is captured and there are no releases to the atmosphere.
In the simplistic representation of the magnesium thermodynamic cycle shown below the TecEco kiln provides de carbonation of MgCO3.

The Tec-Kiln is distinguished from existing kilns in that it grinds and calcines simultaneously in a closed system, making use of the heat generated by grinding to assist with calcination[2]. The low temperature requirements make it easy for the Tec-Kiln to operate using non-fossil-fuel energy, such as solar power.
The TecEco Tec-Kiln is unfortunately somewhat secret due to patent matters. It is however an essential part of our grand plan to sequester massive amounts of CO2 using magnesium compounds.
Summary
The Tec-Kiln has the following features:
- Runs at low temperatures minimising the development of lattice energy and therefore suitable for making reactive MgO.
- Can be powered by various non fossil sources of energy such as solar energy or waste heat.
- Grinds and calcines at the same time thereby running 25% to 30% more efficiency.
- Captures CO2 for bottling and re-use to for example make bio fuels using algae
- The products – CaO and/or MgO can be used to sequester more CO2 and then be re-calcined. This cycle can then be repeated.
