Olson Trust is using abandoned sugar plantation water resources and Keaiwa Reservoir to produce hydroelectric energy for farms along Wood Valley Road. Olson Trust workers recently laid pipe, drained the reservoir to repair it and set a course down the hillside to give the water the drop it needs to make electricity.

Olson land manager John Cross said the goal is to make the new Ka`u Coffee Mill and macadamia husking plant totally “green and using only renewable energy.” Cross said that Olson also plans to use the excess water for additional agricultural projects such as growing watercress and a loi system to grow kalo – taro – and perhaps make poi. The irrigation water is already used for coffee trees, taro, and truck crops grown by farmers leasing the Olson Trust land.
The scanner assembly that uses CCD usually has sensors arranged in three rows. These sensors have different filters such as the green, blue and red. Hand Scanner: In the early 1990s, equally drum scanners and flatbed scanners were too costly for simple home use. For that reason a number of companies produced small hand-held scanners. The hand-held scanner is available in two different forms such as 3D scanner and document scanner. Film Scanner: Special equipment is used to scan films. Film floor covering are moved crosswise a lens by using a 'stepper motor'. The CCD sensors placed inside the scanner, further scan these films.
