New Cameras on Mars!

Posted by in categories: internet, space

The flow of raw images sent from Mars, straight to the Web, has begun!


Insight begins sharing raw images on mission website.

There was jubilation when InSight landed, but I’m just as happy to be writing about a distinct InSight event: The flow of raw images sent from Mars, straight to the Web, has begun. The Jet Propulsion Laboratory has begun sharing images from InSight’s two cameras to the mission website. You can check this website any time, any day, to see if there are new images from Mars, and sometimes, you’ll be able to see them even before mission team members do. Here, for example, is the first image returned from InSight’s Instrument Deployment Camera, sent straight to the Web.

Destroying nuclear waste to create clean energy? It can be done

Posted by in categories: climatology, internet, nuclear energy, solar power, sustainability

If not for long-term radioactive waste, then nuclear power would be the ultimate “green” energy. The alternative to uranium is thorium, a radioactive ore whose natural decay is responsible for half of our geothermal energy, which we think of as “green energy.” More than 20 years of research at the European Centre for Nuclear Research (CERN), the birthplace of the internet and where Higgs boson was discovered, demonstrate that thorium could become a radically disruptive source of clean energy providing bountiful electricity any place and at any time.

Coal and gas remain by far the largest sources of electricity worldwide, threatening our climate equilibrium. Non-fossil alternatives, such as solar power, use up a forbidding amount of land, even in sunny California, plus the decommissioning will pose a serious recycling challenge within 20 years. Solar is best used on an individual household basis, rather than centralized plants. Wind requires an even larger surface area than solar.

As Michael Shellenberger, a Time magazine “Hero of the Environment”, recently wrote: “Had California and Germany invested $680 billion into nuclear power plants instead of renewables like solar and wind farms, the two would already be generating 100% or more of their electricity from clean energy sources.” Correct, but the disturbing issue of long-term nuclear waste produced by conventional, uranium based, nuclear plants still remains.

Twenty-First Century Warfare: Secret and Silent Frequency Wars

Posted by in categories: biotech/medical, internet, military, mobile phones

It’s imperative that Humanity understands the reality of warfare in these times when advanced and secret technologies are used against us on a daily basis.

From WiFi and cell phone frequencies to televisions and microwave ovens on up to the most exotic sonic weapons—it’s all disruptive and even lethal to the Human body and mind.

Because these weapons are silent and invisible, the war-loving aspects of society have been able to experiment with these methods for decades but the time for secrecy and these covert attacks on the life on our planet has come to an end.

Bosch Boosts IOTA With New Device Connectivity For IoT Data Collection

Posted by in categories: bitcoin, cryptocurrencies, engineering, internet

Multinational engineering and electronics giant Bosch recently highlighted a new device connectivity method which will work with the Iota marketplace, among other things, for real-time IoT (Internet of Things) data collection and sales.

Data Collection for the IOTA Marketplace

In a recent blog post the firm opened with a quote from 1999 from Nobel Prize winner Milton Friedman extolling the virtues of anonymously transferring funds on the internet, way before cryptocurrencies were even conceived. It continued to elaborate on the Iota ecosystem, its advantages over Bitcoin, and why it has been chosen as a partner.

Stretchable thermoelectric coils for energy harvesting in miniature flexible wearable devices

Posted by in categories: biotech/medical, engineering, internet, wearables

Miniaturized semiconductor devices with energy harvesting features have paved the way to wearable technologies and sensors. Although thermoelectric systems have attractive features in this context, the ability to maintain large temperature differences across device terminals remains increasingly difficult to achieve with accelerated trends in device miniaturization. As a result, a group of scientists in applied sciences and engineering has developed and demonstrated a proposal on an architectural solution to the problem in which engineered thin-film active materials are integrated into flexible three-dimensional (3D) forms.

The approach enabled efficient thermal impedance matching, and multiplied heat flow through the harvester to increase efficient power conversion. In the study conducted by Kewang Nan and colleagues, interconnected arrays of 3D thermoelectric coils were built with microscale ribbons of the active material monocrystalline silicon to demonstrate the proposed concepts. Quantitative measurements and simulations were conducted thereafter to establish the basic operating principles and key design features of the strategy. The results, now published on Science Advances, suggested a scalable strategy to deploy hard thermoelectric thin-films within energy harvesters that can efficiently integrate with soft material systems including human tissue to develop wearable sensors in the future.

Thermoelectric devices provide a platform to incorporate ubiquitous thermal gradients that generate electrical power. To operate wearable sensors or the “Internet of Things” devices, the temperature gradient between the surrounding environment and the human body/inanimate objects should provide small-scale power supplies. Continued advances in the field focus on aggressive downscaling of power requirements for miniaturized systems to enhance their potential in thermoelectric and energy harvesting applications. Integrated processors and radio transmitters for example can operate with power in the range of subnanowatts, some recent examples are driven via ambient light-based energy harvesting and endocochlear potential. Such platforms can be paired with sensors with similar power to enable distributed, continuous and remote environmental/biochemical monitoring.

Scientists to create ‘truly unhackable’ network based on quantum physics

Posted by in categories: computing, internet, quantum physics, security

Scientists are planning to create a network in the Chicago area tapping the principles of quantum physics. The idea is to prove that quantum physics could provide the basis for an unhackable internet.

This, they say, could have wide-ranging impact on communications, computing and national security.

The quantum network development, supported by the US Department of Energy (DOE), will stretch between the DOE’s Argonne National Laboratory and Fermi National Acceleratory Laboratory, a connection that is said will be the longest in the world to send secure information using quantum physics.
