Battery technology has not kept up with computing power, storage densities and communication speed increases that all follow something similar to Moore’s Law that states computing power will double every 18 months. The sad truth is that batteries have not really come very far in 50 plus years. Alternatives are needed whether it is your iPhone or a Tesla.
Check out this new development that was so hyped 10 years ago as it seems it might be near use in real life. Click here to read about the New Battery that can last for a week.
Here is another article about this Battery Technology and Cars.
Thanks to my techie friend Steve Meyer for turning me onto this pending technology.
Smoke testing is a term used to describe the testing process for servers after patches are applied. 
Estimating an average time for patching servers and PCs can be a bit tricky. It can vary from one month to the next, depending upon the number and complexity of the patches released by your software vendors. You must consider all versions of operating systems and have a complete inventory of all your application software to do this job correctly. Our experience has shown that manual patching of systems takes on average of about 1.5 hours each.
This is a basic cost calculator for you to compute your typical monthly cost for patching your servers, PCs, laptops, tablets and associated application software. It also forms the basis for you to begin calculating your Return on Investment for software patching, or for comparison with alternatives to the manual process of patching operating systems and application software—such as Patch Management as a Service, also known as Vulnerability Management as a Service.
