Why aren't more people researching ways to better store and utilize solar energy so that it could potentially be a viable alternative to currently existing power sources? The fact that there's an infinite amount of light across the universe would seemingly make it an incredibly promising power source (especially in fields such as space travel) right? Are we actively trying to find more effective ways of storing and utilizing it or have we hit some kind of limit in terms of progress we can make with the technology we have available at the moment?
