Staircase to the Moon

By Anupum Pant

Broome is a coastal town in the Kimberley region of west Australia. Every year when all the conditions perfectly fall in place, a very interesting and brilliant natural spectacle occurs. They call it “Staircase to the moon“. It indeed looks like stairs reaching to the moon. Thousands of tourists and the local people gather to watch it happen.

For it to happen the weather, sunset, moonrise and the tide conditions all need to be perfectly right. Before I tell you what happens there, look at a picture of this natural phenomenon. (Or it won’t seem very interesting if I tell you about it first).

Staircase-To-The-Moon

This happens only during the low tide at the coast when the moon is rising. During the low tide, the mudflats get exposed and the rising moon creates this mesmerising reflection on the sand.

The natural phenomenon can also been seen from other coastlines at Onslow, Dampier, Cossack, Point Samson Peninsula, Hearson Cove and Port Hedland.

$20 Parking Ticket to NASA for Parking on an Asteroid

By Anupum Pant

Michael Stevens from Vsauce never ceases to amaze me with his facts. Recently, while watching a video on the channel, I noted this interesting story.

About 11 months before NASA’s ‘NEAR Shoemaker’ spacecraft landed on the asteroid 433, Eros, Gregory W. Nemitz claimed its ownership. He somehow got it registered and waited for the NASA’s probe to land on the near earth asteroid.

The asteroid was estimated to hold several million billion dollars of platinum. When NASA landed their spacecraft on Eros, Nemitz prepared an invoice of $20 and sent it to NASA. According to him, the parking rates on his extra-terrestrial land were $ 0.20 per year and he had decided to charge them to cover the next $ 100 years of parking.

NASA of course refused to pay and sent him a letter denying the payment. In the year 2003, Nemitz filed a case against NASA, saying that they had defaulted his payment.

The judgement was of course against Nemitz as he wasn’t able to prove the actual ownership. There’s no way he could have. Michael explains why…

Space Oddities – Part II

By Anupum Pant
pat on the back self
Self-administered pat on the back to me.

A few days back, in the month of December I had compiled a list of 6 space oddities that really interested me. At that time, I was pretty sure I would stumble upon a few more odd/interesting things about space within a month or two. With that in mind, I had decided to suffix the heading with “Part – I”. Four months have passed. That was a very thoughtful thing I did – thinking 4 months into the future. I have to appreciate my forethought (with a self-administered pat on the back) for doing that because today I’m back with a few more of these odd / interesting things about space and I’m still not embarrassed about the heading for the post.

So, here is the part II of space oddities (read the part I here):

1. A Hole in the Universe

Space Dust Image Gallery

About 7 years from now, researchers from University of Minnesota found out about a really huge void in our universe. The abnormal hole measures approximately sixty billion trillion miles. In easier words, it is about 10 Billion light years wide. Imagine! A beam of light would takes 10 Billion years to travel through that empty place. How lonely would it be at the centre of it. The void is bigger than anything else scientists have ever seen in space.

The whole volume of space shows no sign of any stars, planets, asteroids, gases, clouds, dust. The volume doesn’t even have any signs of dark matter (95% of our universe is dark matter) too. [read more about it]

2. Costliest thing ever built

Think of a huge 5 bed room house floating in space that can be seen moving from the surface of the earth with the naked eye! Yes, I’m talking about the International Space Station. It is a whooping 200,000 kg object that is 171 feet long, 240 feet wide and 90 feet high.

When it comes to the price of building something this huge in space, it beats everything from the most lavish sky scrappers to the most largest dams  ever built. The price of building it is estimated to be about $160 Billion and fortunately the cost is shared by Canada, the European Union, Japan, Russia and the US. It is officially the most expensive object ever constructed, and it is NOT on earth! – Guinness book of World Records.

The Evil Lunar Dust

By Anupum Pant

Space exploration is a tough job. Besides a myriad of challenges that have to be dealt with, space equipment and astronauts travelling to places like the moon or mars, have to deal with a peculiarly wicked foe – The dust.

This isn’t the kind of normal dust we deal with here on earth. ‘Downright evil’ is the phrase that describes the dust on moon! We may not realize it, but lunar dust is a filthy thing and causes a lot of problems. Of course, the dust on mars is no better.

Back in 1972

For instance, let us see how moon dust makes things complicated for engineers and astronauts.

Most of the upper surface of the moon is covered with a mixture of loose material comprising of dust, soil, rocks and pebbles (and other random stuff too). Normally, at places, this layer of mixture ranges from 4 to 6 meters in thickness.

The fine part of this mixture is called the lunar soil and is significantly different from the soil found on earth. It is present almost everywhere on the surface of the moon and is a result of breaking of rocks into small particles by meteorite and micrometeorite impacts; also there is no wind and rain to soften the pieces. This is the part of that loose stuff which is known for causing immense troubles.

The dust is super-fine and extremely hard. You can think of it as collection of little shards of glass. Despite being completely dry, it sticks to everything it touches and as it is super-fine, it can get into tiny creases. If inhaled, it can be toxic; like millions of tiny sharp shards piercing into the inner walls of your respiratory system. A tiny amount of it can eventually kill a full grown man.

Back in 1972, the Apollo 17’s crew learnt this as soon as they stepped out. The dust started clogging their air vents and started dropping the pressure. When returning to their space capsule, Jack Schmitt and Eugene Cernan forgot to brush off the dust. They were stuck with it for the whole time during their journey back home. Some of the dust went airborne in the craft and Schmitt started complaining of congestion. Fortunately, the amount was too small to hurt them a lot. Soon the symptoms subsided and space agencies learnt a lesson – Find a way to deal with the lunar dust.

On mars: Dust on mars can travel places due to dust storms and cause more problems.

Solution

Scientists at NASA found a great way to deal with this dust using an electric zap. They were able to develop electrical fields which can clear about 99% of the dust from the equipment. These dust shields will be tried on in the year 2016.

15 Craziest Ways to Charge Your Phone [Part 1]

By Anupum Pant

What was considered a remarkable method some years back, today, using solar cells to charge your phone has gone too main stream. How about doing it with a flamethrower, or moon light maybe? Brace yourselves up for an unusually long and interesting compendium of some the most craziest things you could use to charge your phone. And of course, I thank science for bringing these things into the world.

Here, I’ve compiled a few crazy ways to charge your phone. Feel free to contribute any others you know and point out ignorance in the comments section below.

Note: The absurd methods I’ve collected here may set your phone on fire, or worse. So, please do not try them at home. If you do, and succeed in melting your phone, do not blame me for it. Or rather, read whatever you can find about it, before experimenting.

1. Moon Light

What if photovoltaic cells were so efficient that they could draw electricity from the moon-light all night? Well, here you go.
A German architect named André Broessel worked on a project for 3 years to put together a novel process of drawing solar energy that would be far more efficient than the existing ones. In the end, he came out with this perfectly spherical glass ball filled with water, which can use up whatever minimum light it receives to create electricity. So, on a cloudy day or even at night (using light from sun reflected by the moon), with this set up on your terrace you’ll be making electricity 24X7. Moreover, you don’t have to worry about the sun or moon moving in the sky. It comes with a tracking system which adjusts itself to capture the light.
It is basically a super-refined version of one of those solar death rays I talked about a few days back.

Your phone is small; this is something which could make whole skyscrapers go off-grid. So, go and give it away on Indie GoGo whatever little you can contribute to the project.

2. Hand Cranked

With the amazing moon light capture device for the future, now let us move on to this hand cranked variant of a mobile power bank, you can buy right now. For everyday use, this backup battery pack comes with a hand turbine power generator that will keep you all charged up all the time. It contains a rechargeable 2000 mAh lithium battery for power which can be cranked up for about a minute to create 4 minutes of battery life out of thin air. If you were expecting free energy, in the end, it is important to know that with this device, to bring your phone from completely dead to 100% battery would require nearly an effort equivalent to a full-body workout.
Also, I found a cheaper variant, which works on a similar principle but isn’t documented well on the internet. It got “India talking” for obvious reasons (costs only $7). They call it the RotoCharger.

3. Lightning

Yes, the same thing that Raijin (雷神) drops on earth 100 times every seconds,  is 3 miles long and carries a current of 10,000 Amps at 100 million Volts, was used to charge a Nokia phone. Last year, scientists from the University of Southampton teamed up with Nokia to try and harness the energy of a lightning bolt to charge a phone. They succeeded in charging a Nokia Lumia 925 with a 200,000 volt lightning bolt, created in the laboratory.

Here is a YouTube video posted by Nokia’s official YouTube channel demonstrating the same:

4. Wind/Air

IfanBlog

In a recent development, researchers at the University of Texas at Arlington have developed a micro-windmill made up of a nickel alloy. It is so small that you could put 10 of them could on a grain of rice. According to them, in the future, hundreds of these tiny windmills could end up in the housing of your smart phones and power them using wind energy.

Earlier, undergrads from Nirma University of Ahmedabad in India had developed an eco-friendly headgear that used a little fan for harnessing wind energy. As it also uses solar energy, at just $22, it is indeed a great device for charging your phone on the move.

Talking about devices that can harness wind energy on the move, the iFan is one ingenious device that comes to mind. It can be mounted on a bicycle or can be held outside a car window to charge your iPhone.

Lung Power: Talking about air, there is this clever gadget that transforms the air from your lungs into energy to charge your phone. Created by Inventor Joco Paulo Lammoglia, from Rio de Janeiro, Brazil, AIRE mask can harnesses the wind power created by breathing and converts it into electricity to run anything from your iPod to your mobile.

5. Body Heat

Working on the same principle as the flashlight without batteries, a jacket developed by Stephen Beeby, Professor of Electronic Systems at the University of Southampton, uses thermoelectricity to power your phone. According to the professor, you have to sleep for quite some time to find a fully charged phone:

Eight hours in the sleeping bag, roughly speaking, will provide 24 minutes of talk time and 11 hours of standby time. That’s assuming the inside of the sleeping bag is 37 degrees – human body temperature.

6. Sound

In theory, talking to your can generate energy to charge a phone. Although to win a substantial amount of battery life from this prototype, you’ll have to scream at the top of your voice. According the lead researcher, Sang-Woo Kim of Sungkyunkwan University’s nanotechnology institute who invented it, it requires 100 decibels to generate 50 milli-volts of electricity. That’s enough to give a Smartphone battery a little support, is still far from what a normal wall plug charger could give you. The researchers are really confident about taking this technology to the next level and making it viable for practical use.

Another one: GotWind’s Sound Charge t-shirt converts sound into electricity. A person wearing this can charge a device battery while thrashing around in the mosh pit. A textbook sized panel of Piezoelectric film in the front acts like a microphone. It absorbs sound waves and converts them into electricity through the compression of interlaced quartz crystals. This electricity is then fed into an external power bank. [Video]

7. Shake

There was a time when kinetic wrist watches were the fad. Today, how cool would it be if you could shake up your phone for an extra boost?
So, Researchers at Virginia Tech tried to make a charger that draws energy from a piezoelectric material and could convert vibrations into energy. They say, when it is done, simple taps on the phone screen or keyboard would produce enough energy to deal with emergencies.

But, long before the researchers announced this, the world had seen nPower PEG. Apparently, it is the world’s 1st human-powered charger for hand-held electronics. It gives you access to backup battery power even when you’re away from home by using the energy you generate while walking, running, or biking to charge your smart phone, music player, GPS, or other devices.

Ah! I’ve written too much for the day. Remember to check back next week for the 2nd part of this post.
