Most of the water in the moon came from ancient asteroids

For several years now, we’ve known that the Moon is not as dry as was assumed for decades, in fact our satellite is harboring a good amount of water. Now a team based at the Open University in the UK is painting a more detailed picture of exactly how that water was transported to the Moon and trapped on what seems like an outwardly arid rock.


The primordial Moon hosted magma oceans

Initial hypotheses assumed that comets were the most likely delivery source for the water found in the interior of the Moon and even near the surface of its soils, but scientists using data from recent unmanned lunar missions like the Lunar Reconnaissance Orbiter and Deep Impact more recently established that water-rich asteroids may have been responsible for most of the water in the Moon.

Row-bot cleans dirty water and powers itself by eating microbes

Inspired by the water boatman bug, a team at the University of Bristol has created the Row-bot, a robot prototype that is designed to punt itself across the top of the water in dirty ponds or lakes, and “eat” the microbes it scoops up. It then breaks these down in its artificial stomach to create energy to power itself. In this way, it generates enough power to continuously impel itself about to seek out more bacteria to feed upon.

The Row-bot consists of two main elements – a propulsion mechanism to move the Row-bot around using a paddle operated by a minuscule 0.75 Watt, brushed DC motor, and its “stomach,” where a microbial fuel cell (MFC) supplies the electric current to the motor powering the paddle. Read more

Venice’s water taxis may be going green

Although most people likely associate Venice with gondoliers quietly poling their boats along the canals, the city is also home to approximately 550 motorized water taxis.

These watercraft are all equipped with diesel engines that spew exhaust and make a racket, creating both air and noise pollution. With this situation in mind, engineers from University of Southampton spin-off company REAPsystems are developing hybrid engines that could be swapped in. Read more

Quench Your Thirst: With Benefit for Yourself and Nature

1. Dam Afsluitdijk, Netherlands. Unreadable name is translated simply – closing dam. It extremely accurately reflects its purpose. After all, a large part of this European kingdom is below sea level, and needs to be protected from flooding. The construction, which appeared in 1933, blocked the way to the sea water, turning Zuiderzee bay into a freshwater lake Ijsselmeer. Incidentally, it is not constructed of sand or concrete, but of large boulders extracted at the bottom of the bay. Read more
