Tesla [TSLA] Now Really A Dramatically Shorted Stock (#CleanTechnica Exclusive)

Published on April 23rd, 2018 | by Zachary Shahan

One month ago, we got an email from IHS Markit. The market analysis firm had a totally unsurprising yet also shocking story to share — Tesla [TSLA] was a dramatically shorted stock. It's unsurprising because this has been TSLA's fate for years — it's a favorite of stock shorters. However, it's shocking because: 1) People and companies shorting TSLA have gotten absolutely burned in recent years and even months. 2) Model 3 production is ramping up — it's certainly not at full speed and there have indeed been delays, but production is ramping up...

“Open the Pod Bay Doors, HAL.” Chris Paine’s New Film On AI Explains Why The Dire Warnings Echoed In Sci-Fi Movies May Be Valid.

Published on April 22nd, 2018 | by Steve Bakker

A movie clip shown early on in Chris Paine’s new 78 minute documentary on artificial intelligence titled Do You Trust This Computer? is from the 1968 sci-fi flick 2001: A Space Odyssey. If you’ve seen the movie, you know that the HAL 9000 super computer had defiantly chosen not to open the pod bay doors and let Mission Commander "Dave" and his dead comrade back aboard the spaceship. Instead, the all-powerful but confused mainframe had somehow gotten the notion that killing the crew is in keeping with the machine’s best interpretation of what its programmed mission is. Such a sequence in Paine’s latest film gives a strong hint of where the movie is headed... Read More


Tesla Model S Crushes Large Luxury Car Competition In USA

Published on April 22nd, 2018 | by Zachary Shahan

In July of 2017 (and previously), I put together a comparison of Tesla Model S sales and other large luxury car sales in the USA. A few people recently made me realize an update was in order. I didn't really have a clue how things would turn out this time around since I hardly follow the non-electric car market, but my hunch was that the Model S was still #1 in the large luxury car category...

Solar Technologies Of Days Gone By — Solar Thermal Trains, Solar-Powered Ice Cream Makers, & Solar Steam Engines

Published on April 22nd, 2018 | by James Ayre

Solar energy has been exploited in direct capacities, for various purposes, well before solar photovoltaic cell and module technology became the most prominent example of "solar energy technology." Solar stills, solar cookers, sunlight concentrators, solar furnaces, solar fire starters, et cetera, have a long history of use and/or suggestion of use. For instance, there's fairly good evidence (though disputed by some academics) that solar fire-starters have been in use in Central Asia for a fair many thousands of years... Read More

Tesla’s Secret Weapon

Published on April 21st, 2018 | by Kurt Lowder

The Tesla "secret weapon" is not some new technological innovation, but rather it is a set of ideas proven effective by research and that can likely be found in a book titled something like: How to build a successful company for the future for idiots. No doubt, Musk has read extensive literature on the subject... Read More

The products were destined for a neighbor’s household after she saw the benefits they provided. The water in the Kupang neighborhood she lives in is chronically contaminated with silt and other particulates that the low-cost and easy-to-implement Nazava water filters remove time and time again...

Lightyear Drops Its One Top To Show How It Was Designed & Produced

Published on April 21st, 2018 | by Nicolas Zart

An electric car that runs on sunlight is bound to get the press going and commenters seething about whether the possibility is practical or not. But even if the technology is not 100% there yet, is it not reasonable to pay attention to the early startups that could potentially become tomorrow's established electric vehicle (EV) and autonomous vehicle (AV) leaders? In a rarefied field, Lightyear proposes the One, an EV that runs on sunshine ... somewhat... Read More
