Elon Musk Unveils Tesla Electric Truck – And A Surprise New Sports Car

Elon Musk unveiled Tesla’s first electric semi-truck on Thursday evening at an event in Los Angeles that also included the surprise reveal of a new Tesla sports car.

The new Roadster, which has the same name as the first electric vehicle produced by Tesla from 2008 to 2012, emerged from the back of one of the trucks at the end of a presentation that focused largely on the economic and performance needs of truck drivers.

The point of doing this is just to give a hardcore smackdown to gasoline cars,” Musk said. “Driving a gasoline sports car is going to feel like a steam engine with a side of quiche.”




While the sports car provided a jolt of excitement for Tesla enthusiasts, much of the event focused on pitching the truck to truck drivers – customers with very different concerns than the average Tesla owner.

In typical Musk style, the CEO had hyped the truck on Twitter throughout the week.

On Sunday, he promised that it “will blow your mind clear out of your skull and into an alternate dimension”, while on Wednesday he teased that the truck “can transform into a robot, fight aliens and make one hell of a latte”.

There was no espresso machine to be seen, but Musk did promise a laundry list of features that he claimed would ensure the overall cost of ownership will be 20% less per mile compared with diesel trucks.

Among them: faster acceleration, better uphill performance, a 500-mile (805km) range at maximum weight at highway speed, and “thermonuclear explosion-proof glass” in the windshield.

Safety features include enhanced autopilot, lane-keeping technology, and a design that makes jackknifing “impossible”, Musk said.

Musk claimed it would be “economic suicide” to continue using diesel trucks, saying the Tesla version, if driven in convoy, would be cheaper than shipping goods by rail.

The CEO’s promises for the new Roadster were no less ambitious. Musk said the car’s acceleration from 0 to 60 mph and 0 to 100 mph, as well as its quarter-mile speed, were all “world records” for production cars.

He said production on the trucks would begin in 2019 and the sports cars would be available in 2020.

Scientists Send Secret Message To Aliens In New Search For Intelligent Life

If the “truth is out there,” scientists are determined to find it – so much so that they’ve spent a message into space trying to contact aliens.

But a response could take 25 years – if it comes at all.

Messaging Extraterrestrial Intelligence (METI) International sent an encoded message into space using radio waves known as “Sonar Calling GJ273b,” which the organization’s president and founder Doug Vakoch, believes could be received by intelligent life.

[The message is] distinctive because it’s designed with extraterrestrial SETI scientists in mind. We sent the sort of signal we’d want to receive here on Earth,” he said in an interview with CNET.




METI’s purpose, along with the well-known Search for Extraterrestrial Intelligence (SETI), has a number of missions, including understanding and communicating “the societal implications and relevance of searching for life beyond Earth, even before detection of extraterrestrial life.

It also conducts programs to “foster increased awareness of the challenges facing our civilization’s longevity” among other directives.

The San Francisco-based METI sent its message toward the red dwarf star GJ 273 (also known as Luyten’s Star), 12 light-years away from Earth.

The message was sent in October from the Eiscat transmitter in Tromsø, Norway and included details such as basic math and science, as well as information on mankind’s understanding of time.

In a statement obtained by CNET, METI said it wanted to know if intelligent life understood the message and then go from there.

While some luminaries, such as Stephen Hawking, have warned against trying to contact extraterrestrials, Vakoch said contact is already being endorsed by many people.

Vakoch added that once news of the initial contact has appeared, it would become almost impossible to stop anyone from trying to contact them on their own.

Once the news gets out that we’ve detected extraterrestrials, anyone with a transmitter can say whatever they want.

Any response probably would be forthcoming in at least 25 years due to the distance the message has to travel between Earth and GJ273b.

The exoplanet was chosen because of its visibility from Earth’s northern hemisphere, even if it is not the closest potentially inhabited exoplanet to Earth. That distinction belongs to Proxima b, which is just 4 light-years away.

Why Renewable Energy Is Good For Business?

Gone are the days where a focus on renewable energy can be relegated to the “environmentally conscious.”

Now, issues surrounding commercial alternative energy solutions encompass a company’s financial performance as well as its corporate social responsibility.

As a result, an increasing number of organizations are taking a deeper look into the benefits of renewable energy for business.




In October last year, the Energy Collective reported that well-known brands including Apple, Bank of America and General Motors are not only looking to reduce their environmental impact but are actively gaining a competitive edge over other companies by investing in and utilizing renewable energy.

These corporations are leveraging their clean energy usage to bolster their business sustainability strategies and financial success. The article states:

Early adopters are building a critical advantage by being ahead of this market …

And goes on to conclude:

… the buying or selling of renewable power directly to corporations will be a barometer of success for businesses of all types.

Far from being simply a fad, investing in renewable energy is taking the stage like never before. Here’s why businesses are taking the concept of using renewable energy seriously:

  1. Consumers are evaluating and prioritizing companies that are committed to reducing and/or eliminating dependence on fossil fuels.
    The Apple brand isn’t only loved for its great technology. Recently, the company illustrated its dedication to sustainability planning by announcing goals for 100% clean energy reliance
  2. Government regulations will likely soon have an even bigger impact on companies and their energy usages.
    In the US, the EPA’s Clean Power Plan may have a significant role in putting the pressure on businesses for clean energy use.
  3. Companies are seeing the advantage of investing in renewable energy initiatives, and the possibility of financial savings.
    A major player in this effort is the Renewable Energy Buyers Alliance (REBA), which is an organization that helps businesses understand the advantages of moving to renewables, and has over 100 major corporate buyers on its roster.

Where, When, And How To Perfectly Watch This Week’s Meteor shower

One of the last meteor showers of the year is happening this Friday. So, if you haven’t caught a meteor shower yet this year, this week is your chance.

Don’t miss out on this year’s Leonid meteor shower, which is expected to have ideal conditions for many parts of the US. Following is a transcript of the video.

The Leonid meteor shower is happening this week. The most meteors will happen on the evening of Nov. 17. Expect to see between 10-20 meteors an hour. Viewing conditions will be excellent this year.




The Moon will be a paper-thin crescent. So, the night sky will be especially dark to enjoy the show.

But watch out for the weather. Cloudy skies will cover some parts of the US. Here are the best and worst places to watch on Nov. 17.

Some of the first records of the Leonids date back to the 10th century. They’re famous for some of the most spectacular meteor showers.

In the past, the Leonids have produced 50,000 meteors per hour. For the best show, find a safe, dark place away from city lights.

Many meteors will appear to come from the constellation Leo. But experts advise looking away from Leo.

That way, you’ll spot the meteors with the longest tails. Happy meteor hunting!

First Earth-Size Planet That Could Support Life Found

For the first time, scientists have discovered an Earth-size alien planet in the habitable zone of its host star, an “Earth cousin” that just might have liquid water and the right conditions for life.

The newfound planet, called Kepler-186f, was first spotted by NASA’s Kepler space telescope and circles a dim red dwarf star about 490 light-years from Earth.

While the host star is dimmer than Earth’s sun and the planet is slightly bigger than Earth, the positioning of the alien world coupled with its size suggests that Kepler-186f could have water on its surface, scientists say.




One of the things we’ve been looking for is maybe an Earth twin, which is an Earth-size planet in the habitable zone of a sunlike star,” Tom Barclay, Kepler scientist and co-author of the new exoplanet research said.

This [Kepler-186f] is an Earth-size planet in the habitable zone of a cooler star. So, while it’s not an Earth twin, it is perhaps an Earth cousin. It has similar characteristics, but a different parent.

Scientists think that Kepler-186f — the outermost of five planets found to be orbiting the star Kepler-186 orbits at a distance of 32.5 million miles, theoretically within the habitable zone for a red dwarf.

Earth orbits the sun from an average distance of about 93 million miles, but the sun is larger and brighter than the Kepler-186 star, meaning that the sun’s habitable zone begins farther out from the star by comparison to Kepler-186.

Other planets of various sizes have been found in the habitable zones of their stars.

However, Kepler-186f is the first alien planet this close to Earth in size found orbiting in that potentially life-supporting area of an extrasolar system, according to exoplanet scientists.

Could This Trick Make You Like Your Vegetables More?

Could we learn to like our vegetables more!? It’s a question that many of us may have wondered, as we struggle to get through a plate of broccoli.

Now, an experiment done with a group of UK school children thinks it might have the answer!

The study wanted to see if it was possible to train ourselves to like a food that we didn’t like before.

To find out, a group of young scientists aged 9 to 11 were split down into two groups.




Half of them were asked to eat a piece of the green vegetable kale every day for 15 days, while the other half ate raisins – and there were some very interesting results!

Most of the kids who ate kale every day found that they did like it more by the end of the experiment.

So, by making yourself eat something you may not really like over a period of time, you could learn to not hate it as much!

However, there were still some in the kale group who really didn’t like it – even after the 15 days was up.

It was discovered this was because they had more fungiform papillae on their tongue, which contain our taste buds.

The more fungiform papillae a person has, the more strongly they will taste flavours – especially bitter ones – so these children are known as ‘supertasters‘.

About one in four people could be ‘supertasters‘, which makes them more sensitive to strong foods, like lemons, spices and bitter vegetables, like Brussels sprouts

Therefore, these people may need to eat kale for slightly longer before they learn to love it.

Jackie Blissett, professor in health behaviour and change at Coventry University, said: “It’s been wonderful to work with these young scientists, and they’ve helped shed some light on one of the great mysteries: why some of us might not like our Brussels sprouts!

New Horizons Discovers Pluto Has Blue Skies and Frozen Water

The first crewed mission to Pluto is going to be a master class in homesickness. After traveling 4.7 billion miles to the icy rock, those future pioneers breathing bottled air, bundled in awkward space clothes, buoyant in low gravity will have little to remind them of home.

But upon landing, they might just ease their pangs of longing by gazing up into the dwarf planet’s sky—which, scientists now know, is blue just like Earth’s.

NASA broke the news today by sharing the above photo of Pluto’s cerulean halo, taken in July by the New Horizons spacecraft.

Like Earth’s heavenly hue, Pluto’s blue sky is caused by tiny, sunlight-scattering particles in the atmosphere. Those particles probably begin as molecular nitrogen and other trace gases.




The sun’s ultraviolet rays break down and ionize these molecules, which then combine into larger (though still microscopic) particles.

The particles aren’t blue themselves; they’re reddish to grey, and are heavy enough that they eventually fall back down to the dwarf planet’s surface.

But wait! There’s more! See those conveniently-colored blue blobs on the above close-up? Those are frozen water, confirmed by combining spectral infrared and visible light data taken by two of New Horizons’ imagers.

What’s compelling to scientists (besides the fact that water exists) is why it appears where it does: on rocky outcrops near craters, and between mountains.

Another mystery is the water’s hue, which appears bright red in color imagery.

The New Horizons team thinks this indicates some sort of relationship between the surface ice and those atmospheric particles responsible for Pluto’s blue sky.

Maybe I’m biased, but those pretty skies and chunks of water make Pluto seem like a pretty good setting for Hollywood’s next lost-in-space blockbuster.

Damon, you up for getting stranded on yet another world?

Artificial Volcanoes Designed To Reverse Global Warming Could Risk Natural Disasters

Efforts are underway to reverse global warming by mimicking volcanic eruptions but such dramatic interventions should be approached with caution, according to a new study.

When volcanoes erupt they spew sulphate particles into the air, cooling the Earth by creating a shield that reflects sunlight away from its surface.

By emitting similar particles into the stratosphere, some scientists have suggested we could imitate this process and reverse climate change in a process termed solar geoengineering.

But creating artificial volcanic eruptions might be as dangerous as it sounds.




New research published in Nature Communications suggests that while geoengineering may indeed have positive impacts, it could also have catastrophic effects in parts of the world already battered by natural disasters.

The researchers used simulations to examine the effect that geoengineering would have on tropical cyclone frequency in the North Atlantic.

While aerosol injections in the northern hemisphere decreased projected cyclone frequency, when applied in the southern hemisphere they could actually enhance cyclone risk.

To make matters worse, the team’s simulation suggested that the positive effects in the northern hemisphere would be offset by an increase in droughts in the Sahel region of sub-Saharan Africa – an area already ravaged by desertification.

The prospect of geoengineering climates may seem remote, but scientists are already engaged in large-scale projects to investigate its feasibility.

The eruption of Mount Pinatubo in 1991 sent planet-cooling aerosols into the atmosphere.

One team at Harvard University estimates the whole planet could be solar geoengineered for the “very inexpensive” cost of $10bn.

Dr Jones and his team suggest that while such endeavours might have positive effects they need to be dealt with on an international scale.

If solar geoengineering were ever to occur, it would have to be in a uniform fashion,” he said.

We are extremely concerned that there is no regulation to stop a country doing geoengineering now. This hasn’t been taken seriously by policymakers so far, and that taboo needs to end.

First ‘Space Nation’ Set To Blast Off From Earth

The first nation in space finally launches Saturday aboard a commercial spacecraft set to blast off from NASA’s Wallops Flight Facility in Virginia.

Although the physical territory of Asgardia will consist solely of what’s basically just a floating file server in orbit, the self-proclaimed “space kingdom” insists the deployment of the satellite Asgardia-1 is just the beginning of a much grander vision of a true space state.

Asgardia is probably one of the few self-declared sovereign states you could fit in a backpack.




Asgardia-1, a small cubesat that’s roughly the size of a loaf of bread, is among the 14 cubesats that will be launched from Wallops early Saturday aboard an Orbital ATK Cygnus spacecraft bound for a long stop at the International Space Station.

It will then have to wait at the ISS for a month before Cygnus detaches and heads to a higher altitude where the satellite can be deployed.

Asgardia-1 will carry some key files, like the national constitution, flag and database of all its “citizens“, but most of its storage is filled with files uploaded by citizens.

So far, over 100,000 humans have accepted the terms of the constitution and uploaded over 18,000 files to the satellite, according to Asgardia’s website.

The reaction to the space nation-building project has been mixed.

While over half a million would-be Asgardians have requested citizenship, others point out that the idea of claiming territory in space could conflict with existing law.

It’s also a stretch to consider Asgardia’s free orbiting cloud storage service an actual nation for even more fundamental reasons.

The ramshackle treehouse I built in my backyard has been declared sovereign territory by at least one young girl dabbling in imaginary megalomania.

But because no other nation on Earth has acknowledged that claim of independence, it carries about as much weight as Asgardia’s assertion of nationhood.
