I could only find mention of waveguides, to evenly disperse the microwaves.

Your typical microwave oven fires a narrow beam, that's why most have the rotating plate to evenly heat your food.

It seems that for sterilization purposes, you need to evenly distribute microwaves everywhere. Including inside the medium I'm assuming is the key.

I know they irradiate some produce.

But again, x-rays, gamma rays anyone? Even your worst microwave contraption is safe compared to those 2.

**Saw the post above me after I wrote this, you're exactly onto the same path as I am**

Which does specify home microwaves are not effective. Unless there's an easy way to modify this, I think we're going to have to start from a more technical angle. No easy street on this one.

Anyone know anything about the production of variable wavelength microwaves?

I'm starting to think lead shielded x-ray box would be a more effective starting point, as x-rays will most definitely kill endospores, and you. I'm sure there's some sort of god damn licensing issue though.



LOL, licensing issue. But seriously, is there any info on the way they modified the microwave?

The problem with this is, THERE WILL BE NO WATER LEFT IN THE JARS WHEN YOU'RE FINISHED. Which is why we sterilize with steam.



After 15 seconds? You can't read either.

Otherwise I've appeared to touch on some dumb stoner nerves.  That must be why so many dumb stoners feel the need to comment.




Chill out.

I find it odd that only dumb stoners appear understand the difference between a cooked loaf of bread having the mold spores on its surface whacked, and wet grains with bacteria and/or bacterial endospores throughout the entire jar(where microwaves don't penetrate).  It's two separate things.  Mold spores are killed by temperature far below boiling.  Bacteria needs 20 minutes at or above 100C, and you can't heat water above 100C in an unsealed vessel.

Naysayers have not held microwave sterilization back.  Repeated failures and the laws of physics have.

there seems to be no proof that microwaves alone kill bacteria. the microwaves heat the water which kill the bacteria.

Where everyone has always failed, someone comes along and succeeds.

Never say nothing can be done. Subtle changes in technique and procedure have changed mycology, even using tools and substances previously thought to be inadequate. The use of coir comes to mind.

With the right vessel, perhaps 15psi for 20 mins in the proper microwave chamber is possible, without losing all your moisture. think of a microwave safe vessel that you could safely have 15psi internally. Make some adjustments to water content, and you could have something.

I'm not saying I could do it. But someone much smarter might could.

I think at this venture that using fire as a heat source is the simplest route. There are less ways to get burned. :rofl:

I would imagine you could use this for LC, and that is about it. The microwave will bring your liquid to temperatures a PC will not, as for sterilizing substrate... Everyone has a point, there will be no water left in your jar, and with all of the failure why do you insist on making it work?

Im a dumb fucking stoner

This is a good point. I suspect you could make this work, but Im sure folk round these parts will say stick to your pressure cooker. Its tried and true.

The Microwave is tried and mostly futile at best.

all molecules have what is called a resonant frequency. leaving out a lot of technical jargon, microwaves emit the frequency that is water's resonant frequency; this is why the water molecules in food or cats you put in the microwave get energy. I am not quite sure how you could modify or improve a microwave to specifically target bacteria/endospores without fucking up something else along the way without dropping a pretty penny on equipment and what not. this is coming from a wireless hardware eng. and physics major.
