problem with making 175 year running battery is........ who is gonna buy more batterys?,(reply>), @Gideon Kloosterman i think perhaps it is you who does not get it. if they make batteries that last ridiculous amounts of time, they'll also make a rechargeable version and people will have nearly unlimited power.,(reply>), Do you guys really don't get it? Putting this in your TV remote would drain it in about a week!,(reply>), Me, as I would put them on everything. Really, the sales of such things would be endless, as people come up with more and more things that they need power for 'forever'.
