Does a living creature require more or less energy to perform a task than a machine? For example, would an 80 kilogram person running a mile require more or less energy in calories than an 80 kilogram vehicle driving a mile?
I'm just curious to know what uses energy more efficiently.
I have heard rare earth metals are practically everywhere in soil. Does that mean if we develop bio leaching commercially we could harvest all rare earth metals anywhere in any country? Or are some rare earth metals really only in few places like any deposit?
I'm having trouble with my computer's search bar giving me results and I was told to follow this instruction https://www.elevenforum.com/t/reset-windows-search-in-windows-11.23308/ which results in opening windows powershell and typing in the following line of code...
PowerShell -ExecutionPolicy Unrestricted -File "$Env:USERPROFILE\Desktop\ResetWindowsSearchBox.ps1"
Before I do that I just want to make sure I'm not doing something to help someone hack my computer. The code looks innocent enough but I don't know for certain.
I noticed Firefox now has a VPN in it's browser. Is it any good? Would you people trust it?
