Turning Photons Into Food

In this video Dr. Bruce Bugbee shows the calculations necessary to determine crop yield potential when light is the only limiting factor. This is now widely used to predict yields in indoor agriculture and vertical farming. The approach starts from the efficiency of photosynthesis (measured as quantum yield), expands to include the efficiency of respiration (called carbon use efficiency) and includes photon capture efficiency and harvest index. The model is called the Energy Cascade Model. It has been used by NASA to model the size of a space farm in regenerative food production. It is also used by the USDA to calculate potential yield of agriculture on Earth.

Wavepiston - a cost-efficient and sustainable wave energy system

Explaining Wavepiston, People, Technology, Business

Price of electricity and desalinated water can be cut in half with wave energy for island communities and remote coastal areas. That is the promise of Wavepiston’s patented technology, based on intensive testing. The Denmark-based company is ready to demonstrate its solution at full scale and is turning to the Seedrs platform to crowdfund final phases of development.
