Sun power makes steam

December 11, 2018

Full steam ahead

The researchers first tested the structure by running experiments in the lab, using a solar simulator that mimics the characteristics of natural sunlight at varying, controlled intensities. They found that the structure was able to heat a small basin of water to the boiling point and produce superheated steam, at 122 C, under conditions that simulated the sunlight produced on a clear, sunny day. When the researchers increased this solar intensity by 1.7 times, they found the device produced even hotter steam, at 144 C.

On Oct. 21, 2017, they tested the device on the roof of MIT’s Building 1, under ambient conditions. The day was clear and bright, and to increase the sun’s intensity further, the researchers constructed a simple solar concentrator—a curved mirror that helps to collect and redirect more sunlight onto the device, thus raising the incoming solar flux, similar to the way a magnifying glass can be used to concentrate a sun’s beam to up a patch of pavement.

With this added shielding, the structure produced steam in excess of 146 C over the course of 3.5 hours. In subsequent experiments, the team was able to produce steam from sea water, without contaminating the surface of the device with salt crystals. In another set of experiments, they were also able to collect and condense the steam in a flask to produce pure, distilled water.

Chen says that, in addition to overcoming the challenges of contamination, the ‘s design enables steam to be collected at a single point, in a concentrated stream, whereas previous designs produced more dilute spray.

“This design really solves the fouling problem and the steam collection problem,” Chen says. “Now we’re looking to make this more efficient and improve the system. There are different opportunities, and we’re looking at what are the best options to pursue.”

Boring, but informative:

re: the expansion and contraction phases of the universe..

August 20, 2015

Hello,
I have recently been assigned the task of reading through 622 reports, respectively the transcripts of conversations had by Billy Eduard Albert Meier over the past 40 years. Some of these conversations have to do with the history of our universe, solar system, planet, and ancestors. Who he is having the conversations with is debatable, but the factual statements made in the conversations can be scientifically verified. There are also topics pertaining to physics, astronomy, and biology. They should at least be considered as theories and tested as such.

  • The age of the universe,
  •  the appearance and disappearance of bodies in our solar system,
  •  the percentage of dark matter that constitutes the universe….
  •  the expansion and contraction phases of the universe..
  •  biological life forms that live in extreme environments..

All of these topics are discussed and explained in great detail.

Please visit http://billymeier.wordpress.com
to see excepts from outer space related topics.

Or download the PDF I have assembled…

If vetted and verified by more people, this information could greatly increase our understanding of the cosmos. Please respond in the comments section after you have looked at and read some of the information and let me know what you think!

Thank you.

On the Odds of Intelligent Life Beyond Earth

February 4, 2014

Would you believe me if I told you that there were planets beyond our solar system?

How many do you think there might be?

Well, there are 1000 we have officially identified, 2500 we have yet to confirm, 17 billion estimated to be about the size of Earth, and 8.8 billion estimated to be the size of Earth and in the “habitable zone”.

Do you think we are the only intelligent, two arm, two legged beings in the Milky Way galaxy?  Because there are 8,800,000,000 other planets around our size and distance to its star.   Just in our galaxy, mind you, not counting the billions of other galaxies.

Would you believe me if I told you that there were high ranking officers in the U.S. military that broke their sworn oath to secrecy and are willing to testify before Congress that they have seen UFOs, or seen top secret evidence on UFOs, or E.T. technology, or touched UFOs that were not from Earth?

There are more than 400 of these people.

So, how many reasons exactly do you need?

Ceres asteroid vents water vapour

January 22, 2014

By Jonathan Amos Science correspondent, BBC News

Observations of the Solar System’s biggest asteroid suggest it is spewing plumes of water vapour into space.

Ceres has long been thought to contain substantial quantities of ice within its body, but this is the first time such releases have been detected.

The discovery was made by Europe’s infrared Herschel space telescope, and is reported in the journal Nature.

Scientists believe the vapour is coming from dark coloured regions on Ceres’ surface, but are not sure of the cause.

One idea is that surface, or near-surface, ice is being warmed by the Sun, turning it directly to a gas that then escapes to space.

“Another possibility,” says the European Space Agency’s Michael Kuppers, “is that there is still some energy in the interior of Ceres, and this energy would make the water vent out in a similar way as for geysers on Earth, only that with the low pressure at the surface of the asteroid, what comes out would be a vapour and not a liquid.”

The quantity being out-gassed is not great – just 6kg per second – but the signature is unmistakable to Herschel, which was perfectly tuned to detect water molecules in space.

The telescope’s observations were made before its decommissioning last year.

Scientists will get a better idea of what is going on in 2015, when Ceres is visited by the American space agency’s Dawn probe.

The satellite will go into orbit around the 950km-wide body, mapping its surface and determining its composition and structure.

“It will be able to observe those dark regions at high resolution, and will probably solve the question of what process is creating the water vapour,” explained Dr Kuppers.

Ceres is often now referred to as a “dwarf planet” – the same designation used to describe Pluto following its demotion from full planet status in 2006.

The asteroid’s sheer size means gravity has pulled it into a near-spherical form.

It is regarded as quite a primitive body in that it has clearly not undergone the same heating and processing of its materials that the many other objects in the asteroid belt between Mars and Jupiter have experienced.

Scientists suspect water-ice is buried under Ceres’ crust because its density is less than that of the Earth’s. And this reputation as a “wet body” is supported by the presence of a lot of minerals at its surface that have water bound into their structure.

One theory to explain why Ceres has so much more water-ice than other members of the surrounding asteroid population is that it formed further away from the Sun, and only later migrated to its present location.

This could have happened if perturbed by Jupiter, whose gravity plays a key role in corralling the asteroids in the belt they occupy today.

“We now have a more sophisticated model for the evolution of the Solar System called the Nice model, which successfully explains many of the features of the Solar System, with the planets having migrated outwards and then maybe also inwards,” said Dr Kuppers.
