Scientists are always thinking about ways to make things more energy efficient. As we grow into an always-expanding mobile world, we are becoming more dependent on batteries, or something that can store power that is harvested from an eco-friendly power source, such as sunlight.
Batteries may even one day power our homes. Although creating battery arrays can be incredibly expensive at this point in time, Tesla CEO Elon Musk is trying to change that with a Lithium-Ion wall battery that holds 7-kilowatt hours on a single charge on the market for around $3000. Best of all, they can last a whole decade.
But for everyday people like you and I, this price is still relatively high. Battery technology is always growing around us. Scientists continue to reveal interesting new power storage concepts and new battery technologies that offer various useful attributes, such as fast-charging, high storage, or even bendable battery packs.
Soon, in the future, our homes may be powered by battery technology, rather than direct hook-ups to your local power plant. What you can expect from this are fewer power surges, more dependence on the Sun and other natural resources that don't damage the environment for charging, and power that can be easily stored for when power plants have problems keeping up.
