A NEW battery-like device has been developed which opens the possibility that people could one day "recharge" mobile phones, laptops and other portable electronics in an unlikely way - with a fix from a sugary fizzy drink or even a shot of vegetable oil.
IN AN electrifying first, American scientists have plugged into algae cells and harnessed a tiny electric current. They found it at the very source of energy production - photosynthesis, a plant's method of converting sunlight to chemical energy.
RENEWABLE energy is a hot topic these days with bold targets set to boost the amount of electricity we generate from devices like wind turbines and biomass-fuelled heating and power-generation systems. The five renewable sources used most often are biomass, hydro-power, wind, solar and geothermal.
