How to mine Solana for free?

I'm curious to know, is it really possible to mine Solana for free? I've heard about the potential profitability of cryptocurrency mining, but the costs of hardware and electricity can be substantial. Could you elaborate on any legitimate methods or strategies that might allow someone to mine Solana without incurring significant expenses? Are there any specific software tools or platforms that support free mining of Solana, or are there any potential risks or limitations I should be aware of before attempting to mine this cryptocurrency?
