I'm guessing he won't be putting himself in the firing line! -- "By 2030, you will own nothing and be happy about it." - Klaus Schwab, World Economic Forum CEO.

"There are also 10 mutations on the receptor binding domain part of the variant, compared to two for the Delta variant" "looks like vaccine evasion could be real with this variant" So much for the spike protein being heavily conserved. The amino acids can change as long as they work the same way or better. Looks like we are going to have a nice holiday surprise! -- Rick C. ...

The Daly-Antra types of BMS (Battery Monitor Switch) require charging current before they'll turn on. Unfortunately, most 'smart' inverter/chargers won't turn on until the battery is connected, so guess what happens when a Daly-Antra BMS is used? Nada. That's what happens when a Daly-Antra . . . .
