Petrol cars are dead in the water, says Tesla CTO waving numbers on the back of an envelope

Re: Is it really cheaper?

Petrol or diesel is about 30%-40% efficient. Electric is about 90% efficient from battery to motor, but there are efficiency losses in charging up the battery. That is where I get my 2x figure from.

Is it really cheaper?

Petrol and electricity both cost about 12p per kWh in the UK. Diesel is about 10p per kWh. An electric car is about twice as energy efficient as a petrol or diesel car so that does make it cheaper. However the only reason it is cheaper is because tax on electricity is 5%, whereas tax on petrol and diesel is about 70%, so the tax is cheaper, not the fuel cost.

Re: Windows can detect metered connections!

On my laptop the network is a Parallels Virtual Network connection, and from there it might go out to the internet via a local cable or wifi connection, public wifi, or bluetooth/USB via my phone. The Mac side of things knows which one it is, the Windows side does not.

Re: 5 minutes

Would that work? When a card is declined, the merchant isn't told why it is declined, it could be insufficient funds, account closed, blocked or doesn't exist, or bank thinks the transaction is fraudulent. Usually if a company wants to verify a card without taking any money, they do an authorisation-only transaction for £1, $1 or whatever and let it lapse without collecting the money.

Re: 5 minutes

"Credit Card verification. As you can only own a credit card if you are over 18."

That's not strictly true. You can only be required to pay money back if you are over 18, but it is possible for an under-18 to get a prepaid credit card, or garantor credit card if someone over the age of 18 is prepared to guarantee the balance.

Hurrah! Windfarms produce whopping ONE PER CENT of EU energy

jonathanb
Silver badge

Re: Why's this a story?

Denmark can produce more because it is connected to the European Grid and can export it. 10% is about as high as we can go without reliability problems, for Europe and North Africa as a whole. That breaks down as about 1/3 Denmark, 1/3 UK and Ireland and 1/3 for the rest of Europe, mostly along the north coast of France, Belgium and Germany. So there is some potential for future growth, but not much. In Southern Europe and in North Africa, solar has much more potential, because the sun shines when they need the most electricity to power their air conditioning.

Re: No Skype?

$264m profit, on a 33% share of the international calls market, and it is a very mature market with little growth prospects.

Vodafone trades at 11x earnings. Skype, probably less than that, because Vodafone has spectrum licences that other potential new entrants don't have.

$1bn would have been a good price. $1.5-$2bn would have been an OK price. $9bn was way too much.

Skype

What about Skype?

It's a decent enough company, sound business model, makes a profit and so on, but Microsoft vastly overpaid for it. The problem was that there was little growth potential because everyone was already using it, and had the risk of losing market share to new entrants such as Google Talk, WhatsApp and Apple's FaceTime.

Re: On German Economics Between the Wars

Spain (and Ireland) had budget surpluses before the crash, so clearly their tax departments were collecting enough money to pay for everything. Their problem was that they had a real estate bubble due to too-low interest rates, which then burst, causing a banking crisis which meant they needed a lot of money to bail them out.

Re: Let's do the maths

Is it like the UK where they count the same money multiple times and add it all together?

For example, if the three people jointly received the money, they are each treated as individually receiving the full amount.

If the money passed through multiple accounts before reaching them, they add together all the transfers in to each of the accounts but don't deduct the transfers out.

If they receive an asset other than cash, they add together the value of the asset and the sale proceeds from selling it.

Retailers don't have access to card info?

Is it true that retailers don't have access to card info? If it was, then it wouldn't work on TFL, but it does, see https://tfl.gov.uk/fares-and-payments/contactless/other-methods-of-contactless-payment/apple-pay?cid=applepay

They know that you've bonked in and out of the network with the same phone/card combination, so they can charge the correct fare for the journey rather than two penalty fares. They know if you bonk back into the network at a nearby station on a different line so they can treat it as a continuation of the previous journey rather than a new one, if it is a recognised pair of interchange stations. They know if you have reached the daily or weekly charging cap and are entitled to free journeys for the rest of the day or week, and they can request a single payment from your bank at the end of the day for every journey you made that day. You can register on their website with your card details to get travel statements showing all the journeys you've made.

Pay TV is very different. There is no natural or legal monopoly. Other companies can and do enter the market, they just don't seem to be able to compete with Sky. Either they enter a niche market that Sky isn't interested in, and that can work, or they sell the channels at a loss which obviously isn't sustainable.

Re: No Coop / Smile ApplePay Support

I was able to set up Apple Pay in about 3 minutes this morning while on the bus, and use it to buy breakfast when I got off the bus. The other offerings require you to set up new accounts, load them with money, get special SIM cards or sticky tags and things like that.

I'm not sure that I'll use it again for shop purchases, but being able to do on-line purchases without entering my card details certainly seems like a useful feature.

If you read the TFL stuff about Apple Pay - https://tfl.gov.uk/fares-and-payments/contactless/other-methods-of-contactless-payment/apple-pay?intcmp=29634 it seems they do know which card you used to pay. They know if you have done loads of journeys with the same phone in that day/week and therefore are entitled to get the rest of the journeys that day/week for free. You can also enter your card details on their website and get details of the journeys you made and how much you were charged for them.

Typing in a 4 digit number isn't hard, but it does take time. A contactless card transaction on Transport for London services takes 0.5 seconds to complete, 0.3 seconds if it is Oyster. A PIN transaction would probably take about 5 seconds. 4.5 seconds may not sound like a major inconvenience, but multiply it by the hundreds or thousands of people in queue waiting to get into the station, and it makes a huge difference.
