    Abstract: A solar water heater absorber absorbs the sun's energy on the surface of a twin-walled polycarbonate panel and conducts the heat from the sun through the panel wall into fluid flow through channels of the panel. The panel is an extruded polycarbonate glazing material that consists of two panes connected by longitudinal ribs to form a plurality of water channels that may further include twisted strips providing a helical water flow pattern that increases turbulence within the water channels. The panel is connected to large pipes or headers on the top and bottom ends of the panel that receive the heated fluid from the water channels, allow the heated fluid to exit the panel, and for return water to re-enter the panel in a solar water heating system.

    Abstract: A kit includes reagents and materials for students to make gRNA and Target DNA, cut Target DNA with Cas9 guided by the gRNA, and visualize the uncut and cut the Target DNA on an agarose gel. The kit may include a shipping box that is able to withstand transport of the reagents and materials, reagents and materials needed to perform the desired curriculum, and the curriculum necessary for using the kit. Additional curriculum may be included with extension activities as desired.

    Abstract: An energy harvesting system can be used to exploit freely available flow energy with a piezoelectric device(s). The system may include a piezoelectric device and a flow disruptor, such as a blunt body that creates flow turbulence and flow characteristic randomization that can increase movement response from the piezoelectric device and enhance electrical power generation. Multiple piezoelectric devices may be linked to each other to enhance movement of a less-influenced piezoelectric device from translated movement of a more-influenced piezoelectric device and create more electrical power than a single piezoelectric device subjected to the same flowing fluid.

    Abstract: Multiple spatially diverse and compact weight sensors are statistically combined to reduce or eliminate errors caused by snow bridging. Data transmission using satellite communication minimizes the power consumption of the sensor station further allowing the entire system to be relatively compact and easily transported. The weight sensors may be combined with other standard sensors for measurement of air temperature and snow height, the latter measurement, for example, using ultrasound ranging or the like.
