Its like i have said the people who know our company have seen enough to know our technology exists and works, now to most companies in the world to day know they have to go carbon free over the next couple of years and yes there are a number of technologies out there to help make this happen. But at the moment there are only two vaible ways of doing this one is lead acid battery technology that has worked in smaller forklifts for years the other is IC engines running on a fuel that allows them to be 100% zero emission. The other two options that some people would talk about both really arn't options the first one is Lithium Iron battey technology. Tesla are the worlds top electric car manufacture and even they admit they can't get enought lithium iron batteries to meet their demand. The second option is Hydrogen, hydrogen to just way to expsensive to be competitive
