DIY Algae Bioreactor from Recycled Water Bottles

In this Instructable, we describe how to build a photo-bioreactor that uses algae to convert carbon dioxide and sunlight into energy. The energy that is produced is in the form of algae biomass. The photo-bioreactor is built from plastic recycled water bottles. By designing the apparatus to be compartmentalized, we are able to do many experiments in parallel. By using algae as a biofuel, we can increase the world’s supply of oil while at the same time we decrease the amount of atmospheric carbon dioxide used during its production. The resulting product is a sustainable biofuel whose carbon footprint is neutral inasmuch as the CO2 produced on consumption is essentially balanced by the CO2 used in its production. In this Instructable, we first make the carbon dioxide delivery system, then mount the water bottles on a rack, and then inoculate the bottles with algae. After letting the algae grow for a week, we extract the biomass.

Farmers receive Indigo carbon credit payments

Indigo Ag today issued the second set of payments totaling more than $3.7 million to farmers through the Carbon by Indigo program. The company plans to issue the second set of carbon credits to buyers in the first half of 2023.

Nearly 450 farmers received payments in the program's second year of producing carbon credits. Farmers who generated credits during the 2020 crop year also received an additional payment to reflect the $30 per credit final payment rate for that issuance, which was a 200% increase over the original minimum payment rate. The program's guaranteed minimum payment rate for the 2021 crop year was $20 per carbon credit, with the opportunity to earn more as the credit demand and price rise.

Major breakthrough in pursuit of nuclear fusion unveiled by US scientists

American researchers have achieved a major breakthrough paving the way toward nuclear fusion based energy generation, but major hurdles remain.

Nuclear fusion is an energy-generating reaction that fuses simple atomic nuclei into more complex ones, such as combining atoms of hydrogen into helium. Nuclear fusion takes place in the cores of stars when vast amounts of molecular dust collapse under gravity and create immense amounts of pressure and heat in the nascent stars' cores.
