Everyone is excited with solar panels and almost every rich guy who builds a house takes into account a power solution to reduce the electric bill to minimum. At the same time, few know that the internal energy (magma) of the planet has a huge potential. For example, only 1% of geothermal reserves in the area of Australia would be able to provide electricity for 26,000 years!

To obtain geothermal energy, are necessary excavations in depth about 5 km through sedimentary rocks hard to granite layer. Water pipes will lower the bottom up, where there will be heated to 270 degrees Celsius, and then extracted back to the station that carried the exchange geothermal heat (Heat exchanger) and produce electricity. Cover electricity needs a proportion of 20% for a continent, such as Australia would require an investment of over 10 billion U.S. dollars, and the project would help more than 10 years.

Military robots are autonomous or remote-controlled devices designed for military applications.

If we stick to this definition, we can say that military robots have been around ever since World War II and the Cold War trough the presence of the German Goliath Track Mine and the Soviet Teletank. But both these robots were simple and made little impact on the war.

It was not until a few years ago (starting with the Second Irak War) that military robots really started to be important in a conflict, and with the technology developing rapidly since, it’s not a wander that more and more defense contractors around the world are working hard at developing autonomous “robot soldiers”. It’s true that these robots look nothing like Arnold Schwarzenegger in the movie “Terminator”, but they seem to be very useful with their tank-liked appearance. Continue Reading…

Studies made on some of the 381.7 kg of rocks and other materials gathered during the Apollo missions (much of which is currently stored at the Lunar Receiving Laboratory in Houston) proved there is some amount of water on the moon but there was no knowledge of how much there was and how to extract it.

In 1994, the SDI-NASA Clementine spacecraft orbited the Moon and mapped its surface. In one experiment, Clementine beamed radio signals into shadowed craters near the Moon’s south pole. The reflections, received by antennas on Earth, seemed to come from icy material.

In 1998, NASA sent another spacecraft, Lunar Prospector, to check. Using a device called a neutron spectrometer, Lunar Prospector scanned the Moon’s surface for hydrogen-rich minerals. Once again, polar craters yielded an intriguing signal: neutron ratios indicated hydrogen. Could it be the “H” in H₂O? Many researchers think so. Continue Reading…

U.S. researchers have created a new electric battery, capable to operate on the basis of sweating or human blood, similar to a simple piece of black paper and which may have a wide range of applications. Researchers have produced a molecular structure formed in proportion of 90% of pulp and proportion of 10% of nano-tubes of carbon that plays the role of electrodes and allow the passage of electric current.

The nanoengineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrow’s gadgets, implantable medical equipment, and transportation vehicles.

The battery works at temperatures from 37.8 to 148.9 degrees Celsius.

Traditional batteries contains a large number of separate components, while components of paper batteries are integrated into a single structure, which makes them more efficient in terms of energy. Further, the paper battery can be rolled up, folded, rumpled or even cut up into several pieces without losing their properties or technical capacities.

Have you ever wanted to find short and fast answers to some of your questions? Well, now you have the possibility to achive that. How’s that? Recently, i’ve found a new site, 17things.com, a site that was set up to bring answers to everyday questions and not only.

Questions like the ones below will always have some answers on this site :

What is a pyramid ?
How long will the universe last ?
What is an aerospace engineer ?

The site is very interesting, and the concept behind it is also excellent. Give it a try, you have nothing to lose.
