Intelligent electric bike trailers

NÜWIEL has developed and built an electric bicycle trailer that automatically follows the movement of the bicycle. The cyclist does not feel the load of the trailer or the cargo. The trailer, thanks to a special coupling, is mounted in a few seconds under the saddle of the bicycle, without the need for further installations. When used without a bicycle, it can also be used as an electrically powered handcart in pedestrian-only zones and inside buildings. Thanks to NÜWIEL’s modular design, the trailer can be used with different cargo structures. It is possible to install an existing transport box system on the trailer, or to develop a custom box for different needs.

Optimization of solar collectors

Aiguasol have designed a solar concentration called 'Ulisses'. Ulisses is a cylindrical concentrator which uses flat movable mirrors rotating on a shaft. Ulisses can be coupled to flat solar collectors or to photovoltaic modules, thereby enhancing their efficiencies and minimizing the cost of power generation. The fact that the mirrors are movable allows the structures and protective systems from wind, snow, and high temperatures to be simplified.

Blockchain for tracking solar energy generation

Sello Sol a certification developed by Phineal allows tracing the solar energy generation on its place of origin through the use of blockchain technology. The data is measured and processed to add value by using it in products, services and transactions as verifiable, transparent and secure information. Phineal states that the blockchain methodology has been tested by companies and public institutions and it is being developed in Latin America for the world

A dispatchable solar power system

The innovation is a temporary energy storage solution for thermal energy. This is done using a phase-change material based on aluminum, which is liquefied by the heat produced. When electricity is required, the heat in the material is transferred from the phase-change material via a heat transfer fluid to a Stirling engine, where the energy is converted to electricity. The thermal energy input can be excess electricity from e.g. solar panels or wind turbines, or heat from concentrated solar energy. This solution allows for storage and releasing of energy on demand based on the needs of the electricity grid.

Surface water cleaning using separation

Surfcleaner removes oil and other waste products such as plastic and debris from water surfaces. This is done using automatic separator that automatically drags in everything (including water) into it. The water is then removed using separation and returned to the water mass while the rest of the materials is transported to a secondary storage unit that can be emptied at will. The device itself is cheap and requires minimal service while also having a long lifetime. The solution can be applied to specific situations such as oil spills or wastewater treatment, but also for general for areas such as plastic collection.

Biological toilet solution

ECOLOO is a toilet that is waterless, sewage free, energy free and requires low maintenance. The toilet is not using any water for flushing, the only water that could be required is for secondary functions such as cleaning the toilet or for personal hygiene. All the human waste is broken down to tiny particles and can then be used as fertilizer. The solution avoided emissions by reducing the need for fresh water for flushing, eliminating the need to treat sewage water and by creating fertilizers when being used.

Hyperloop development

Hyperloop is a new means of ground transportation that can carry passengers and cargo at speeds up to 1000 km/h inside low-pressure tubes. Zeleros' hyperloop system minimizes infrastructure complexity to achieve a scalable solution that will enable long-distance travel. By integrating Zeleros’ main levitation and propulsion technologies in the vehicle, the electrification needs of infrastructure are reduced, resulting in lower costs and easier maintenance. The fully-autonomous vehicle enables the use of a tubular infrastructure which has reduced construction and maintenance costs in comparison with other high-speed ground transport systems.

Solar powered water distribution

Spowdi® is a solar powered water distribution system that can replace traditional diesel using the energy of one solar panel. The portable irrigation and drinking water supply system also reduces water consumption in irrigation by 80% and has a low energy consumption. Using a drip irrigation system also results in reduced extracted water volume/hour, allowing a more stable extraction from groundwater sources. With few parts in one system, the line of products are easy to use and to apply in different situations.

Power quality improvement in electrical networks

Comsys has developed the ADF (Active Dynamic filter) to reduce problems caused by a veriety of electrical disturbances that weakens power quality. The ADF is a low-harmonic solution that uses harmonic compensation and mitigation resonance for power quality improvement in an electrical network. The solution is modular and adaptable, meaning that it can be applicable to different types of industries. The solution can also replace existing transformers in a network. The solution can help generating energy savings, higher productivity and reduce the number of failure in a network.

Coolar refrigerator using solar heated warm water

Coolar has produced an electricity-independent medical refrigerator. The Coolar system uses warm water that is heated through solar energy and stored in a water tank. It does not use any moving parts, hazardous cooling fluids or lubricants. Thus, the Coolar system is a cheap, durable and sustainable solution for storage of vaccines, medicines and food in regions with unreliable or expensive electricity. The Coolar system runs independently from electricity by using solar heat, which makes it almost carbon neutral. Such a refrigerator can enable doctors and health professionals to preserve lifesaving medicine and vaccines in a reliable and eco-friendly way.
