While silicon solar cells dominate the solar power generation market due to low cost, high-end technologies such as multi-junction and light-concentration devices may be more suitable for energy harvesting applications, in which the required device surface is much smaller and the power value is significantly higher, by at least two orders of
This work is concerned with a mechanical system designed to harvest Crocus Sativus (saffron) flowers. The system is conceived as a shoulder portable device with two main parts: the first one is specifically designed to detach the flower containing three stigmas, which are the costly final product; the second one is aimed to collect the detached flower through a vacuum collector. The system is
Mar 18, 2024 · Wastewater pipelines are present everywhere in urban areas. Wastewater is a preferable fuel for renewable electricity generation from microbial fuel cells. Here, we created an integrated microbial fuel cell pipeline (MFCP) that could be connected to wastewater pipelines and work as an organic content biosensor and energy harvesting device at domestic waste-treatment plants. The MFCP used a
