it's huge, it's better than lithium eyon. the cost is a little higher. you say you're going to bring the cost down. i think you have to promise you're going to keep writing the cost down. those utilities are not going to stand by and watch you do this and sign off their business. they're going to cut their cost and deliver cheaper and run at a loss to drive you away. what have you got going on that's going to make this cheaper and cheaper and cheaper? scale or innovation? >> well, there is a scale. any type of scale product is down. i have a great opportunity to do that. but we have a chemistry which is about half the cost of battery. and we store energy separate through generation. so that we never have any pladine. my storage will last forever. it should theoretically -- >> once you put the energy into the battery, it will stay in that battery. we recharge it and over and over and over. those are two different things. how do you keep bringing the costs down? >> the energy will stay in the battery forever or the battery will be recharged forever. >> it
