  1. 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
  2. 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
  3. 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
  4. where are we now? • Busy designing and testing new

    solar concentrators • Experimenting with steam turbines
  5. where are we now? • Busy designing and and testing

    new solar concentrators • Experimenting with steam turbines
  6. our next steps 1) Finishing the design and mechanics of

    the solar concentrator 2) Designing the heat exchanger part of the concentrator 3) Assembling solar concentrator and testing it 4) Researching the usage of turbines for power generation 5) Designing and assembling solar tracker for concentrator 6) Experimenting with automotive turbines and finding cheap solution for pressurized steam utilization 7) Designing heat storage 8) Assembling heat storage 9) Integrating heat exchanger of the concentrator with heat storage 10) Integrating heat storage with turbines/generator units 11) Evaluating the performance of the heat storage 12) Adding security controls 13) Finalizing integration of the system 14) Testing and optimizations
