Why did you select to use concrete to make the form? Did you consider plaster?
@brunokagi109021 күн бұрын
I chose cement because it remains a long time, even in rainy weather. So you can make several reflectors one after the other. But I actually also used gypsum (see 8:00 - 9:40) because it can be sanded finer than cement. Perhaps I should have used the term "plaster" instead of "gypsum"; it's probably just a translation error, sorry.

Hi, Bruno, when I aim a laser pointer at kitchen foil, the reflection is a line! (It should be a dot but there are tiny scratches or grooves on alu foil that make a line reflection). I have checked with thin alu sheet too and it also gives a line reflection. So, where do I get good (Mirror like) reflector? Thanks Brian
@brunokagi10907 ай бұрын
Hello Brian! That's a very good idea to test the alu foil with a laser pointer. Sorry I didn't reply sooner, I was traveling and away from my alu foil collection. Today I tested them and noticed big differences. In fact, the thin household foil is the worst, the one I used (self-adhesive, covered with a plastic layer) is the best. A plastic foil generally used for wrapping presents also performed well. Its reverse side is mirror-smooth and colorless. I will test other films when I get the chance, but for now these tips must suffice. Thanks for the tip! There is still room for improvement.

@@brunokagi1090 Thanks for your reply, Bruno. I never expected this! I though it would make a blurry dot. I did more tests and aluminum foil here in Canada, produces a line in one direction and it produces a nice semicircle in the other direction! And I think the reason is because the aluminum has grooves in it (like the roof of a farm shed) and the grooves cause the line in one direction and semicircle in the other direction. Its very interesting but someone should have warned us years ago. I made parabolic dishes a decade ago and I had no idea that aluminum foil was a horrible reflector. I made a bad video about it on my main youtube channel, and I will replace it with a better one soon. I also found research from India, where they tested different coverings. They thought vinyl car wrap was worth the extra cost because it was about twice as good as foil. They also found "mylar" good.

Hello Brian! I have now found a mirror film that reflects quite well and with low loss: It is a self-adhesive film from the German company d-c-fix.com, the film can be ordered online from the manufacturer (www.d-c-fix.com). Article no. F2150013. This film is quite stiff, so it compensates for irregularities in the surface, but must be cut into small pieces before application because it does not adapt to the curvature of the shape.

Hi Moussa Maadani! I think that this cooker is not suitable for producing electric energy. A better solution would be a trough-shaped mirror that focuses sunlight on a black copper tube. This would turn water into steam, which could be used to produce electricity. But this is something completely different from my cooker with a parabolic mirror.

@brunokagi1090 Жыл бұрын
Hallo Sam! Der Aufwand war tatsächlich beträchtlich. Aber erstens kann man mit der Form Dutzende von Parabolspiegeln herstellen, und zweitens ist es z.B. in der Savanne auch sehr aufwendig, Brennholz fürs Kochen zu suchen, es nach Hause zu schleppen, zu zerkleinern und dann noch beim Verbrennen den giftigen Rauch einzuatmen. Und wenn ich an den Aufwand denke, der für die Erstellung eines elektrischen Kochherds getrieben wird, dann bin ich doch recht zufrieden. Schliesslich zwinge ich niemanden dazu, meinen Vorschlag nachzuahmen. Perfektion ist schwierig zu erreichen, aber wenn Du Verbesserungsvorschläge hast, so bin ich neugierig, sie kennenzulernen!

Guten Tag Herr Hopf! Meine Auftraggeberin war an meiner wissenschaftlichen Erhebung nicht interessiert, daher brach ich die Bekämpfung des Japanknöterichs an diesem Standort nach 4 Jahren ab. Danach habe ich auch nicht mehr besonders auf neue Vorkommen geachtet. Entlang der Aare wird der Japanknöterich, soviel ich weiss, durch Freiwillige periodisch bekämpft. Da die vollkommene Ausrottung dieser Problempflanze aber praktisch unmöglich ist, werden Sie sicher noch Restbestände finden. Auskunft könnte Ihnen ausserdem [email protected] geben, und auch neo.infoflora.ch/de/index.html zeigt die aktuellen Standorte invasiver Neophyten auf.

Danke für Ihr Lob! Tatsächlich ist der von Ihnen erwähnte Weg sehr schön. Hoffentlich bleibt das Engnis in seiner Mitte bestehen, sonst ist mit mehr Verkehr zu rechnen. Gemäss historischen Karten wurde dieser Weg erst in den den 1940er Jahren gebaut, ist also wahrscheinlich nicht historisch. A propos: Einer der schönsten Wegstrecken St. Margrethens ist meines Erachtens der sog. Bollensteinweg, mit wunderschönen alten Edellaubbäumen; aufgrund seiner Lage könnte er sogar historisch sein (Erschliessung der früheren Rebberge und Verbindung zwischen Leuchen und St. Margrether „Weite“), ist aber erst in jüngster Zeit auf Karten abgebildet.

Normal household alufoil should work. The perfect reflective material does not exist, but the better the reflection, the faster you can cook. If you have a choice between thick and thin aluminum foil, choose the thick one, because it compensates for unevenness of the surface. When sticking, the better reflective side should be visible.
