HANNOVER, Germany - HE Energy GmbH, based in Wismar in northern Germany, is at LIGNA 2017 in Hannover to present a world first - the e-stove.
This stove, which is on the brink of being launched onto the market, is a wood-nano cogeneration unit for producing heat, electricity and hot water for the home, heating the living room and lighting it with LED lamps. Visitors to LIGNA can see how the innovative e-stove generates heat and electricity in live demonstrations.
The e-stove can also be used as a backup if conventional heating systems stop working after a power failure, for example. The current yield of up to 0.5 kilowatts covers the energy required by heating pumps and controls, LED home lighting and mobile devices. A key aspect of this innovation is the use of thermoelectric generators (TEGs), which enable direct conversion of thermal energy from the wood fire into electrical energy.
The e-stove uses logs to produce electricity via the wood gasification technique, and via thermoelectric means in the form of maintenance-free and noiseless thermoelectric generators.
In wood gasification, the exhaust gases from the combustion chamber are not directly fed to the stack (as in conventional furnaces), but are instead diverted into a second combustion chamber for post-combustion. Thus energy utilization from the wood is increased to greater than 92 percent.
For decades now, this reliable technology has been used to supply energy to space probes far from Earth, for instance - albeit without a wood fire. TEGs were also used by the 2011 NASA mission within the scope of the "Mars Rover Curiosity" program. HE Energy will be in the outdoor space at LIGNA.
HE Energy is looking for silent investors and strategic partners, for example, from the construction sector (e.g. property development companies), the energy sector (e.g. battery suppliers/manufacturer) and the photovoltaic sector (e.g. manufacturers/suppliers).
Private investors acquiring shares in HE Energy GmbH will receive 20 percent of the issue price of their stake refunded under the German Federal funding scheme known as "INVEST."
