It is old tesla and new tesla.
Describe it in a different way then. For example, "redone" or "reconstructed blueprint" of tesla generators etc.
Like I said somewhere in the past, you should get someone to check your English before you publish. Just like the previous "comming soon" title, lots of people made fun of that.
I'm failing english honestly due to the shitloads of semester marks being dependant on silly essays, but surely my english grammatical skills are somewhat better than yours.
If you were to hire me to check for you, my fixes may be wrong to some people because Australian spelling can be different (such as colour, that's a common one that annoys me when doing a cvar search in the console). However grammar should be the same.
Long story short: I'm indirectly saying you should hire an English checker of some sort, but don't hire me.
