What’s Holding Electric Cars Back? The Cost of Batteries. And Tesla’s About to Fix That.
Self-described Tesla fanboy Vivek Wadhwa predicts that Elon Musk's car company will re-invent the battery industry by the end of the decade.
Vivek Wadhwa is a Distinguished Fellow at Carnegie Mellon University's College of Engineering. He is a globally syndicated columnist for The Washington Post and author of The Driver in the Driverless Car: How Our Technology Choices Will Create the Future; The Immigrant Exodus: Why America Is Losing the Global Race to Capture Entrepreneurial Talent, which was named by The Economist as a Book of the Year of 2012; and of Innovating Women: The Changing Face of Technology, which documents the struggles and triumphs of women. Wadhwa has held appointments at Duke University, Stanford Law School, Harvard Law School, Emory University, and Singularity University. You can follow him on Twitter @wadhwa.
Vivek Wadhwa: I call myself a Tesla fanboy. I've been driving a Tesla for a year. It's to the point that I can't drive regular vehicles anymore. If you recall the first time you got an iPod, it was amazing wasn't it? You went from a cassette player to this amazing little device on which everything was "solid state.” You remember solid-state electronics and so on? But this amazing advance we saw in technology, that's what it feels like to drive a Tesla.
I call it a spaceship that travels on land. No gears, no bumps; you step on the accelerator, the car literally flies and it flies so fast that when my wife is sitting with me, she complains, “Vivek, we just had dinner. Please, I'm going to throw up if you go like that.” Because it feels like you're getting into warp speed. The car literally, seamlessly picks up torque like you wont believe and flies. This is the future of the transportation industry that we're going to have clean vehicles that fly. That's the magic of electric.
Now what's holding back this industry is the cost of batteries. Knowing Elon Musk, he's going to far exceed his anticipated 30 percent savings by 2017. I wouldn't be surprised if by the end of this decade we're talking about batteries costing a fifth as much as they do today; if not a fifth, maybe a third, which means that it becomes more economical to produce electric, clean vehicles which are like spaceships then to deal with the filthy internal combustion engines that we're dealing with right now — these machines that we put that horrible liquid into, that explosive liquid called petroleum, and then you have to load them up with that black viscous liquid called oil, pollute the environment. These cars are as clunky as hell.
Those internal combustion engines, it's time for them to go. We need to replace them with electric engines, and this is why I've become such a Tesla fanboy because it's the first real electric vehicle that is better than anything else ever made.
Why does self-described Tesla fanboy Vivek Wadhwa like Elon Musk's car company so much? Because it's not just a car company. As we explored last week, Tesla is gearing to make a major announcement this week that could spark a reinvention of the battery industry. The reason Wadhwa loves Tesla so much is because its technology blows away everything we've ever seen before.

Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

Building a personal connection with students can counteract some negative side effects of remote learning.
- Not being able to engage with students in-person due to the pandemic has presented several new challenges for educators, both technical and social. Digital tools have changed the way we all think about learning, but George Couros argues that more needs to be done to make up for what has been lost during "emergency remote teaching."
- One interesting way he has seen to bridge that gap and strengthen teacher-student and student-student relationships is through an event called Identity Day. Giving students the opportunity to share something they are passionate about makes them feel more connected and gets them involved in their education.
- "My hope is that we take these skills and these abilities we're developing through this process and we actually become so much better for our kids when we get back to our face-to-face setting," Couros says. He adds that while no one can predict the future, we can all do our part to adapt to it.
Construction of the $500 billion dollar tech city-state of the future is moving ahead.
- The futuristic megacity Neom is being built in Saudi Arabia.
- The city will be fully automated, leading in health, education and quality of life.
- It will feature an artificial moon, cloud seeding, robotic gladiators and flying taxis.
