Have you thought about using the motorization of a telescope?

So there, a medal! I hope you realize that you only buy certificates of origin?

Hey besides it's day, Ekwateur, supplier of "green" electricity, attacks EDF in front of the commercial court by invoking force majeure in order to reduce its contractual purchases of historic nuclear (ARENH) !!!! Find the mistake!

Edit: the sentence on the Ekwateur home page:
Choose an electricity and green gas supplier
100% renewable electricity, gas and wood for your home, it's possible! Switch to a more transparent, more digital and cheaper energy in a few clicks: we take care of everything!

It is possible to motorize tinytech india kits (its CEO is a big fan of Gandhi. They are serious)

On the video, they operate the oven by hand, but there is an external marker. A small camera should make it possible to adjust the two axes.

Completely agree, it is not a panacea, but it is better than doing nothing. Self-production is by far the best guarantee. I chose solar thermal because it is less efficient at conveying heat than elec. We should be able to do 'slow-cooking' with a 90deg water circuit ... but I have not yet seen a baking tray of this type. Then, 20% of PV yield to then produce heat seems delusional.

That's why a solar oven seems interesting. Well, it's gray today ...

Do you not find it surprising that there is no technically successful solar oven on the market for Western consumers looking for a robust / practical solution?

moarteen wrote:Hello everyone,

how to get the simplicity of a conventional oven thanks to a solar cooker?

Not having the desire or the time (at least for now) to hack this project (Arduino, R Pi, etc.), I am looking for a technically successful commercial solar cooker:

- parable
- motorization of the axes of rotation / tilt.
- cooking probe
- setting a cooking program
- setting of a desired end of cooking time
- control of the location (GPS) and the time.
- enslavement to local weather forecasts.
- forecast of the best execution of the desired cooking program taking into account this local weather.
- execution of the cooking program by controlling the axes of rotation / tilt, in particular to reach / maintain the temperature curve expressed in the program.
- piloting / control via web interface or via an app.

It seems a lot, but all this is technically possible, is not unduly complicated, all the data is online, all the automations are accessible, for example via Arduino etc ...

Does such a product exist commercially? Who would come closest to it?

Thank you,
Have a good day,
Martin bowen


Bonsoir
Is there a need to redo a "thermo-mixo-bidule" solar version?!?
"the simplicity" of a gas plant .... the cost will explode unnecessarily, why want to add layers of electronics-gadget on lowtech? : Evil:
it is "thermo-mixo-bidule" repainted in green ....

what do you call "technically successful solar oven" and "robust / practical solution"?

Good idea! But it could be expensive, compared to an Arduino / motors hack

I meant that suddenly it is better to produce heat locally.

Thanks for the links! Some are great to discover.

If I had to summarize my point, I look for (and may have to tweak it myself) a solar oven whose use is as simple as possible compared to a conventional thermal oven. Obtaining this level of comfort is obviously only possible if solar gain is guaranteed. otherwise compromises of comfort are necessary. But assuming that the sun shines all the time, what a clever combination of low-tech means (and I put the Arduino and other small positioning motors in this category) would achieve this level of comfort, as I started to put it in the beginning of the subject?

To read you, I see that it remains a challenge ... that deserves to be taken up, see the ~ 10 years that we have left to completely change our way of life in order to survive with dignity on this Earth.

Used, it should not cost much. I don't know I have never looked for this kind of product.

okay, you're looking for user comfort (a few buttons to push, and that does the rest by itself)
> "Arduino and other small positioning motors" is no longer lowtech! :frown:
even ultra-simple analog electronics is limit ...
