SJapanese engineers who were tired of
quickly draining batteries revealed a prototype of a thermoelectric device that could create electricity using heat produced from laptops, which means more renewable energy and less time being plugged into a wall. When two ceramic semiconductors with different temperatures are connected, an electrical current is produced, creating power, which means that cell phones, laptops, mp3 players and other portable devices can partially recharge themselves. However, it may take more than 10 years before self-recharging gadgets will be available to consumers, so don't worry — you can still use your laptop as a personal heater for the upcoming winter.
