Boil The Ocean Status Updates

Filed under: Project: Boil the Ocean — Tags: , — admin @ 2:54 pm

We’re moving forward with the research and initial system design for Project Boil the Ocean. During the past month, we set up a secured server system for data acquisition, controls, surveillance, and automation. This system allows for remote monitoring and data acquisition, similar to the wind farm test rig for Project Mustard Seed but with more fail-safes and advanced design features.

We also explored various concepts for solar thermal collectors, and have decided upon a central-receiver type of solar collector design. Compared to parabolic troughs and Fresnel mirror systems, a central-receiver-type system is capable of much higher efficiencies, which means more power in the same area. A naval but simple design is in works for creating a field of solar tracking mirrors and central receiver using inexpensive, mostly off-the-shelf hardware. According to a 2003 study by the National Renewable Energy Laboratory (NREL), for a solar thermal power plant, the solar collectors represent nearly half of the total costs that go into building a solar thermal plant, followed by about 15-20 percent of the costs for the receiver.

As always, if you are interested in becoming involved with this project, or have ideas about other projects that you would like us to be involved with, visit our “Become Involved” page.

Small Scale Solar Thermal Power Systems: For You, For Me and for the World

Multiple groups are in the process of developing small-scale solar thermal power systems for remote areas where utility power is not readily accessible. A not-for-profit group, STG International, based in Massachusetts is working to provide electricity and hot water to off-grid schools and clinics using solar energy technology. The for-profit Promethean Power Systems is developing a solar-powered refrigeration system for commercial cold-storage applications in off-grid and partially electrified areas in developing countries.

According to Popular Mechanics, these design concepts are using Solar arrayparabolic concentrators to collect solar thermal power. Utilizing an Organic Rankine Cycle (ORC) generator, the systems are able to produce electric and heated power. Total hardware costs for the STG system are only $3,000 for a one kilowatt electric power with water heating system. Automotive parts and other off-the-shelf components are used to keep costs low.

The approach of these groups is in line with what we at OMS and Project: Boil the Ocean are attempting, right down to the use of creative hardware parts for cost efficiency.

For you…for me…for the world.
