As an electrical engineer who has been in the crypto space, this idea crossed my mind:

 Build mobile mining units equipped with solar panels and batteries that can be deployed to remote locations or rural areas with abundant sunlight. Offer these units as a service to Bitcoin miners looking to decentralize their operations and reduce reliance on fossil fuels. provide power for house holds and also provide mobile solar-powered irrigation systems. Two products: one supports bitcoin mining and the other(irrigation) does not; however, both have incentives in some redeemable green energy credits.
 
My idea is specifically targeted for the African market with poor electricity, low irrigation activities, and the least financial inclusion.

The aim of this idea is to:

• Promote green mining
• provide electricity for house holds
• support irrigation activities
• and also support Bitcoin decentralization

Your inputs and criticism are welcome.
Thanks
