One computer company is working to add solar power to its portable devices, while another is developing a touch screen for the next version of its widely used software.
Macrumors.com, a website that closely watches developments at the Apple computer company, says the firm has asked for a patent on adding a solar panel to generate electricity for its portable phones and computers. What is new is the idea of putting the solar panel beneath the devices' display screens and touch screens, saving space.
Apple's competitor, Microsoft, is developing a touch screen for the next version of its Windows software. The touch screen could take over some of the work now done by a keyboard or computer mouse.
