  2. challenge

    Renewable energy is at the core of
    sustainable development

    Not everyone can use renewables due to
    tecnological, financial and regulatory
    barriers

    Electricity grids are often restrictive

    Existing renewable energy soultions are
    often too expensive

  5. how it works
    1) Fresnel lens concnetrator focuses solar rays onto the heat receiver.
    Temperatures at the focal area may exceed 800° C. Solar tracker governs a system
    of stepper motors which position concentrator precisely to get maximum amount of
    solar rays
    2) Heat reciever transfers heat to salt solution which circulates to the high-
    temperature storage. At this stage salt solution is used, as it can store more
    thermal energy at higher temperature than water.
    3) High-temperature heat storage is an extremely well insulated tank which
    purpose it to store extremely hot salt solution with minimal heat loss. Such storage
    provides opportunity to generate electricity and heat whenever user needs it,
    independent of the rapidly changing. Industrial variants of heat storage can store
    heat at around 800° C up to 5 months. In our case, we plan to be able to store that
    temperature for 10 days.
    4) Through a system of heat exchangers the thermal energy from salt solution in heat
    storage is used for turning water into pressurized vapor which moves steam
    turbine. We plan to re-use automotive steam turbines, commonly found in many
    vehicles with internal combustion engines. Heat recuperation system condenses
    the used steam back into the water
    5) Steam turbine is connected to AC generator which produces electricity for the
    users

  6. advantages
    The powerplant we are designing will have a series of
    advantages:
    – Completely open-source. Available for commercial or non-
    commercial usage.
    – Electic power output — 3-10 kW (depending on number of
    turbines/generator used)
    – Easy-to-replace mirror segments
    – Can be built and assembled in non-industrial settings
    – Modular design
    – Delivers power when needed independent of weather
    – Does not require grid
    – Scalable
    – Allows for maximum usage of local materials
