The cons are more substantial than you say

    The disadvantages are more substantial than you say, the initial cost of a solar is not "moderately expensive". It is very expensive. Even with government subsidies and tax exemptions, it's still expensive. Just by making a lot of dubious assumptions about degradation, the escalation of the cost of energy, do solar energy providers manage to quote equilibrium times of 20 to 25 years? Without government subsidies and tax exemptions, it is a certain economic loss. 
    The cost has to be reduced to make solar energy really viable as an alternative for most environments. The fact that solar energy is useless most of the day is not an insignificant problem, especially because the part that is lost is the night when most houses need more electricity, not less. Factories and offices can make good use of solar energy during working hours, but that is not true for owners. And it is quite inefficient during the day in many areas, where heavy clouds or low sun angle limit the energy gain.
     If you are not connected to the network on top of a mountain or in the middle of the desert, it may be your best option, since small-scale generators fueled by fossil fuels are inefficient and expensive to operate, but for most owners, they have a public utility at hand. Which brings us to the batteries. An important expense and they do not last as long as the solar cells. So this "initial expense" is repeated every few years. 
    The defenders of solar energy usually do not mention it. And batteries present a new danger to the environment, something very little mentioned. While we're in ... what about electronics? Quite expensive for a great system. "Without moving parts" does not mean it lasts forever. How many iPhones are dead in a year or two? How is that digital control in the dishwasher? However, I will discount the problem of space. Most people have a roof they can use. The electronics are small enough. Batteries can be placed almost anywhere, even in an outdoor shed if necessary. But the price of solar energy has to go much lower before it becomes an economically prudent move for most people, even with government subsidies. I'd love to see it happen, but I think it's still far away.

Energy used for specific jobs

    One thing that is not discussed here is the energy used for specific jobs only power.  For example, refrigerators turn on and off. Therefore, a refrigerator that runs almost full time can be cooled with the same energy but at lower power than a cycle in which each cycle consumes more energy. Energy = Power for time. Secondly, all kinds of devices now use motors in inverters or other electronic devices that control the frequency or voltage, giving the motors only the speed and, therefore, the power needed to perform a specific job. On-demand water pumps come to mind and offer only the pressure and flow rate required and nothing more. Needless to say, the power required is only what is needed for that pressure and volume. So far, less energy is wasted. Apparently, the team that is discussing works according to this principle. But, whether DC is operated from rectified AC or inverted DC to Poly Phase AC, the specific design used is unknown.

Transfer technique produces wearable gallium nitride gas sensors

------------------------------------------------ Transfer technique produces wearable gallium nitride gas sensors A transfer technique based on thin sacrificial layers of boron nitride could allow high-performance gallium nitride gas sensors to be grown on sapphire substrates and then transferred to metallic or flexible polymer support materials. The technique could facilitate the production of low-cost wearable, mobile and disposable sensing devices for a wide range of environmental applications. Transferring the gallium nitride sensors to metallic foils and flexible polymers doubles their sensitivity to nitrogen dioxide gas, and boosts response time by a factor of six. The simple production steps, based on metal organic vapor phase epitaxy (MOVPE), could also lower the cost of producing the sensors and other optoelectronic devices. Sensors produced with the new process can detect ammonia at parts-per-billion levels and differentiate between nitrogen-contain
