Thank you for bringing progressive and positive news to our awareness. In the bottom-line-business-as-usual-goldmine-frenzy of the economic market place - it's inspiring to see the predominantly progressive mindset of the blockchain community's big players.
Solar power = decentralised power generation for a decentralised blockchain paradigm - bring it!
Nevertheless, there's still an apparent inefficiency to our current technology so long as so much surplus / un-utilised heat is generated (server / mining farms, etc.) which makes me wonder about the relative energy input in the creation of cryptocurrencies vs gold / fiat and so on... but I for one have great faith in blockchain and solar mutually and exclusively ;)
