algae aquaculture systems with pumps, control, andsolar cells (Figures 4 through 8). The system is made out of clear acrylic plastic sheet (3 to 5mm thick). The sheet is cut with a Universal Laser Systems 40W CO2 laser using AutoCAD orSolidWorks source files. The acrylic is bonded with acrylic cement (Weldon 4052), but ingeneral, all adhesives and materials should be checked for toxicity to algae.The channel height (normal to incident sunlight) is about 1 cm. The widths of the channelsranges from 4 to 8 cm, and can be up to 1-2 m long. Flow rates range from 1 to 10 ml/s, whichcorresponds to a Reynolds Number of about 20 to 500, and a flow velocity of 1 cm/s, indicatinglaminar flow. Syringe pumps are gentle to the algae, and peristaltic pumps

, and farther from their day-to-day needs. Eventhough each individual house may have increased insulation, better windows, and high efficiencyheating and cooling systems, the total energy use goes up because of the larger size, greaternumber of electrical gadgets, and farther travel distances. More generally, this tendency forincreases in efficiency to lead to greater energy use is called the Jevons Paradox.2 These trendsare illustrated in Fig. 1. House size increased slowly through the 1980’s and then more rapidly inthe 1990’s and 2000’s. Because housing codes and building practices generally improved theefficiency of houses with time, the energy use per square foot steadily declined. From the 1970’sto the 1980’s, total household energy use

through photosynthesis by future biomass crops.In 2011, it was discovered that bioenergy was used as an energy source more than oil in Sweden.The Swedish Energy Agency found that 31.7% of the energy used was generated from biomasswhile 30.8% of the energy originated from oil. One of the principal reasons for this increase inbioenergy is the fact that biomass is the primary energy source in the district heating sector, asector that demands more than half of the overall heat demand in residential areas. 7 Figure 5shows the different sources of energy in Sweden in 2011 (Sweden Energy Use 2010, May 10).

In order to train such engineers, thecourses are needed to highlight the unique engineering challenges presented by renewable energysystems. A key element of our
