Abstract
A bioreactor and bioreactor system are suitable for the growth of materials from algae. More specifically, the system preferred embodiments use concentrated sunlight in a solo- or co-generation system to produce algae and products therefrom as well as solar thermal energy.
Claims45
A photobioreactor system, comprising:
- a receiver with an aperture, a solar concentrator, the receiver being positioned to receive concentrated sunlight from the concentrator through the aperture;
- an array of flat members with respective first surfaces, the flat members forming a cascade with each being positioned and oriented to receive substantially one sun or less of solar flux or less than 1000 Watts per square meter the first surfaces through the aperture;
- a fluid conveyance configured such that, by gravity, a fluid received by a first of the flat members runs down the first flat member first surface and is conveyed to a second of the flat members and runs down the second flat member first surface.
A photobioreactor, comprising:
- a receiver with an aperture;
- an array of flat members forming a cascade, each being positioned and oriented to receive light transmitted through the aperture;
- a flux regulator located at the aperture configured to selectively block radiation components passing through the aperture.
A photobioreactor system, comprising:
- a receiver with an aperture, a solar concentrator, the receiver being positioned to receive concentrated sunlight from the concentrator through the aperture;
- a fluid conveyance with surfaces and a mechanism to control the flux received on the surfaces through the aperture to a level less than one sun or about 1000 Watts per square meter;
- the fluid conveyance conveying fluid consisting substantially of algae and liquid media where the dry mass of algae is 25 g. per liter of the fluid.
A photobioreactor system, comprising:
- a receiver with an aperture, the receiver being configured to receive light through the aperture;
- an array of flat members with variegated surfaces forming recesses and peaks, the flat members being positioned to receive light on the variegated surfaces when transmitted through the aperture;
- a fluid conveyance that includes the flat members configured such that, by gravity, a fluid received by a first of the flat members runs down the first flat member first surface and is conveyed to a second of the flat members and runs down the second flat member first surface;
- the variegated surfaces configured such that fluid pools in at least some of them at a depth of 20 mm or less.
