Blockchain-Enabled Electric Car Charging Comes to California

I&#x27;d love to have an alternative to ChargePoint for charging my Tesla at airports. It takes multiple minutes of diddling around with their app to make their charger&#x27;s relay contacts close. They have reviews within their app, wherein people report which of their chargers usually work, which sometimes work, and which never work. In no case is the actual power faulty -- it&#x27;s their monetization strategy that fails to tough-luck.<p>Back in the early 80s, I spent part of a summer in a slate-roofed cottage in Wales. The cottage had a box in which you had to insert a coin to turn on the electricity. Like, if you wanted to cook or watch TV that night you had to insert a shilling coin and turn a knob and --- kerchunk --- you&#x27;d have electricity until you&#x27;d used up your 1d worth of kilowatt-hours and then --- kerchunk --- you were a savage again.<p>Somehow, paying for electricity at each act of consumption feels bad. Like paying for toilets.<p>Tesla got it right. I paid $100,000 for the car -- I want hassle-free electricity, thanks.

I read the article and no where does it make a case for why a blockchain makes any sense in the application. I read a comment by a person claiming to be associated with the project saying that &quot;blockchain enabled&quot; makes sense because the payment are p2p but that doesn&#x27;t make sense either. Blockchains are good for pretty much one thing: a distributed ledger that parties can trust to be immutable. I can confidently say they&#x27;re only inserting a blockchain here because it gets the idea more buzz.<p>Side note: I had no idea people paid so much to charge they&#x27;re EVs. the article mentioned that a electric bill in Cali can be upwards of $1000&#x2F;yr.<p>Edit for clarity: the $1000&#x2F;yr figure is the marginal cost of charging the EV, not the entire bill

Cryptocurrency enthusiast here.<p>This is exactly the sort of nonsense that people are doing that makes other people think the entire cryptocurrency community is a joke. Obviously there is no benefit to having this on a blockchain here. You can just pay the charging station.<p>I made a comment the other day that there is very little overlap between cryptocurrency enthusiasts and people who want to blockchain-all-the-things. It was heavily downvoted and I suspect people didn&#x27;t believe me, so I&#x27;m going to keep repeating it until people believe me :)<p>Don&#x27;t write off cryptocurrency just because of nonsense like this. Bitcoin, Ethereum, and Monero (and a small handful of other coins) are genuinely worthwhile projects.

As someone associated with this project, I can inform you that the reason the words &quot;blockchain enabled&quot; are used is because the Share and Charge platform enables peer-to-peer payments between car charger and private (not commercial) charging pole owner via the blockchain. As it happens however, as this is a pilot in a new country (US) with new compliance requirements, there are no actual cash payments taking place for now. And as for the electricity cost of Proof of Work, we&#x27;re actually looking to move to a special purpose chain using Proof of Authority in the near future.

Perfect! Put a few tons of carbon in the air pointlessly calculating hashes to mine *coins, and then use those e-coins to charge your electric car.<p>This uses Ethereum so when they eventually move to proof-of-stake I&#x27;ll mostly retract my scorn, but for now I stand by this being counterproductive and dumb.

But why is there a blockchain?<p>Why not just charge people?<p>Crytocurrencies both have large advantages AND disadvantages.<p>The advantage is that it is a decentralized, censorship resist currency. But if you don&#x27;t care about the decentralized part of it, then there is no point. Just use a credit card.

OT, can anyone explain this idiom to me?<p>&gt; <i>The peer-to-peer concept relies on blockchain, one of today&#x27;s hottest trends [...]</i><p>Note the missing article. Not &quot;relies on <i>the</i> blockchain&quot; or &quot;relies on <i>a</i> blockchain&quot; but &quot;relies on blockchain&quot; as if that were some kind of new elemental resource like water or electricity.<p>I&#x27;ve noticed that expression in quite a few articles. DOes anyone know where it comes from?

Brought to you by Slock.it, the company that built the DAO, what could possibly go wrong.

&quot;If bitcoin is digital gold then Ethereum is digital oil&quot; analogy taken too seriously.
