My suggestion is use the server to mine raptoreum and you will make at least 100x lightning fees.
As n0nce has said, I am not really doing it to make a ton of money. If that were the case, I would open far many more (large) channels.
so instead of emphasising the 31cent 'energy cost' mention the $3 confirmation lock cost to peg into ln and the $3 cost to unpeg out of LN ($6 to use LN before even doing any 'payments')
You seem to be stuck in 2017/2018. Transaction fees have been extremely low for quite some time now. Even 1 sat/vbyte is enough to get a transaction confirmed quickly. The smallest possible opening transaction with change weights ~152 vbytes (
transaction;
channel). That transaction cost only $0.07.
