    There is no atmosphere on the moon to stop the solar winds from depositing He3 in the surface of the moon.

    It's all in the article. :)

    The problem is that there is no information content that could determine a broadcast of 'something'.
    Einstein spoke of 'spooky action at a distance'. It is a communication without any exchange of information.

    The measurement of condition of the one particle causes a change of condition at its entangled partner particle. This takes no time.

    Entanglement is something that exceeds our basic idea of the universe and assumes a connection.

    It also affects philosophical matters such as Realism. (Realty is objectively random. There is no hidden variables which can have influence on a single measurement. Particles have a determined condition regardless if somebody looks at them or not. Means measurement itself and devices do not have any influence.)

    Another problem is that I have no clue what so ever on how a warp drive engine would work :rolleyes:

    Never-mind, you would already fail getting enough energy for it. (More than there is in the universe at all, except you create another fantasy "exotic matter". Matter that has a negative mass or even better negative energy itself).

    A recommendation to watch:

    "One Strange Rock" Host Will Smith. One Strange Rock is an American television documentary series.

    It has been broadcasted on free TV and is currently available on Netflix.
    https://en.wikipedia.org/wiki/One_Strange_Rock

    Watching the series will change your view on the Earth. You will experience how well-balanced things on Earth are and how much 'luck' humankind had to become how it is today.
    How precious anything is but vulnerable and fragile at the same time.

    Fantastic vivid and stunning pictures. Culture and many scientific aspects and relations. Natural Powers, Balances and Life on Earth. Commented by Astronauts who had been lots of days outa space.
    Free of politics. Pure beauty. Blue Planet.

    Love it! :)

    Oh, my...

    "Europe has the capacity to produce more than 100 times the amount of energy it currently produces through onshore windfarms, new analysis from the University of Sussex and Aarhus University has revealed. In an analysis of all suitable sites for onshore wind farms, the new study reveals that Europe has the potential to supply enough energy for the whole world until 2050. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019-2029."

    Silicon's energy-harvesting power

    A University of Texas at Dallas physicist has teamed with Texas Instruments Inc. to design a better way for electronics to convert waste heat into reusable energy. The collaborative project demonstrated that silicon's ability to harvest energy from heat can be greatly increased while remaining mass-producible. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019-2029.

    Dr. Mark Lee, professor and head of the Department of Physics in the School of Natural Sciences and Mathematics, is the corresponding author of a study published in Nature Electronics that describes the results. The findings could greatly influence how circuits are cooled in electronics, as well as provide a method of powering the sensors used in the growing "internet of things."

    "Sensors go everywhere now. They can't be constantly plugged in, so they must consume very little power," Lee said. "Without a reliable light source for photovoltaic energy, you're left needing some kind of battery -- one that shouldn't have to be replaced." Thermoelectric generation is a highly green energy source, converting a difference in temperature into electrical energy.

    crystalline form. But in 2008, new research indicated that silicon performed much better as a nanowire -- a filamentlike shape with two of its three dimensions less than 100 nanometers. For comparison, a sheet of paper is about 100,000 nanometers thick.

    TI Fellow at Texas Instruments, designed and supervised fabrication of the prototype devices. He turned to Lee and UT Dallas to further study what the devices could do.

    "A deep dive for these novel measurements, detailed analysis and literature comparisons requires a university group," Edwards said. "Professor Lee's analysis identified key metrics in which our low-cost silicon technology competes favorably with more exotic compound semiconductors." Lee explained that the nanoblade shape loses some thermoelectric ability relative to the nanowire. "However, using many at once can generate about as much power as the best exotic materials, with the same area and temperature difference," he said.

    nanoscale physics with engineering principles. One key realization was that some previous attempts failed because too much material was used. "When you use too much silicon, the temperature differential that feeds the generation drops," Lee said. "Too much waste heat is used, and, as that hot-to-cold margin drops, you can't generate as much thermoelectric power. There is a sweet spot that, with our nanoblades, we're much closer to finding than anyone else. The change in the form of silicon studied changed the game," he added.

    Lee said that the advanced silicon-processing technology at Texas Instruments allows for efficient, inexpensive manufacturing of a huge number of the devices. "You can live with a 40% reduction in thermoelectric ability relative to exotic materials because your cost per watt generated plummets," he said. "The marginal cost is a factor of 100 lower."

    Gangyi Hu PhD'19, who finished his doctorate in physics at UT Dallas in May, is the study's lead author. He produced the computer modeling to determine the number of nanoblades per unit area that will produce the most energy without reducing the temperature difference. "We optimized the configuration of our devices to place them among the most efficient thermoelectric generators in the world," Hu said. "Because it's silicon, it remains low-cost, easy to install, maintenance-free, long-lasting and potentially biodegradable."

    Lee said the work was also novel because they used an automated industrial manufacturing line to fabricate the silicon integrated-circuit thermoelectric generators. "We want to integrate this technology with a microprocessor, with a sensor on the same chip, with an amplifier or radio, and so on. Our work was done in the context of that full set of rules that govern everything that goes into mass-producing chips," Lee said. "Over at Texas Instruments, that's the difference between a technology they can use and one they can't."

    Yeah, Joe, they contained all that energy and made huge strides towards a goal and yet - it doesn't count... swell...

    I'm not against progress... it just that "we" are at this stage when it comes to being able to harness fusion:

    theirs rumors that US has something like that in area 51 a device that can solve all our energy problems in the world...but it will never see the day of light...why that doesnt help the Illuminati they want all the power and control for themselves.;) I bet the Chinese stole that from us:rolleyes:

    Their what???
    If you could.... would you "do" another gal type of thing from another planet?
    Even if it involves tentacles?
