#Climate #change
saradina-info-blog on 03.04.2020 um 07:21 (UTC) |
| | This year 2020 was almost no winter in our region. Only in March there was some ice and snow in the second half, but only in the higher regions.
It is April, from the second half of March it did not rain properly. Will there be another problem like 2018? | | | |

| | My special admiration is Tillandsia, they are so independent. It would be nice to be as independent as a tillandisia. | | | |

Nutrition #1Solve nutritional problems through photosynthesis?
saradina-info-blog on 02.04.2020 um 13:34 (UTC) |
| | With a constantly growing population in the world and in view of possible droughts, the nutrition of the world population becomes an important question.
On the one hand, herds of cattle and other farm animals need large resources of pasture land, other feed and accommodation on the other hand. If you used these resources on crops for food crops such as wheat, rice and the like, you would be able to feed many more people.
These thoughts speak for a vegetarian or vegan diet for the world population.
Another advantage would be that there would be less cruelty to animals due to factory farming.
But if you think ahead, you can see that the cultivation of food plants also takes away many resources that a natural flora is then lacking. In addition, people would still be dependent on food-producing agriculture.
But the possibilities of science continue every day. With the ever better knowledge of genes and the manipulation of genes, one can imagine that one day it will be possible to implant genes that enable photosynthesis in humans.
Human life would become more peaceful, fewer wars would be fought, and individual dependence would be much less if one did not have to buy food from outside. Huge sales areas could be omitted or could be occupied differently.
If people could do photosynthesis, it would also be easier for people to colonize other worlds in space, the whole of humanity would be more flexible in terms of their living space.
It may sound very new, but it's worth thinking about it carefully.

Special #energy cells can supply #electricity at #night #solar
saradina-info-blog on 05.02.2020 um 13:59 (UTC) |
| | Researchers have developed special energy cells that can supply energy from heat at night and in the dark.
They are not solar cells but a different type of energy cell.
Unfortunately, these special energy cells also have a very low efficiency of 15 percent. And of course they are not yet ready for the market ... | | | |

Poor performance of #solar cells, only 10 percent to 20 percentefficiency
saradina-info-blog on 05.02.2020 um 13:45 (UTC) |
| | Solar energy has long been mentioned as a serious option for generating electricity.
That's why I was always amazed that solar energy has so little practical application for everyday objects.
So I wondered why there are no monitors, tablets, laptops with solar energy.
Small equipment such as alarm clocks and calculators certainly use solar cells, but only in combination with conventional batteries. In this way, the use of solar cells looks more like pure decoration to calm your conscience.
A few days ago I realized a lot. One article I read that researchers proudly reported that they had developed solar cells that could achieve 30nergy efficiency.
These solar cells are an absolute novelty and of course not accessible to consumers.
It will take years before the solar cells with the high degree of effectiveness are ready for the market. Until then, consumers should be satisfied with solar cells that have a low efficiency of 10 percent to 20 percent.
