You may need to double the flow. With the water powered jet packs the water isn’t just being accelerated from a standstill. The water is first flowing up with close to the same speed and is redirected down. So the momentum exchange is twice what it would be if the water were stored in tanks with the flyer.
Yup. Fiber optics can’t feasibly be jammed. The drone is still powered by battery, but is controlled over a fiber that is spooled in the canister on the bottom.
You can’t conclude anything from this video. The variability in his results are much larger than the differences between groups with the exception being that it looks like he nearly killed the seeds in the 120s group. He also didn’t track much beyond germination. A 12hr shorter germination isn’t likely to have much significance in real world yield. His grandiose conclusions assume that accelerated growth rates would perisist, but he didn’t provide evidence of that.
My guess is that there is a short term boost to germination rate, but no long term growth rate difference.
Cold plasma is not psuedoscience though. There have been very interesting results in cold plasma accelerating wound healing. The mechanisms aren’t well known, but seem likely atributable to the in situ production of short lived reactive species such as H2O2.
I would not be surprised if treating seeds partially breaks down the outer layers and increases water permeability allowing faster germination. Mechanical abrasion can be used to accelerate germination in some seeds. If that is the mechanism, then you would only want to treat seeds immediately before planting, as you would be compromising the ability for the seeds to regulate internal moisture levels.
As a rule of thumb, you can usually assume anything from iflscience is trash tier.
In NC at aldi, cage free eggs are $4.50/do. and free range eggs are $5.30/do.
I get that price are regional, but there’s got to be another factor for why the price is double what I pay for pasture raised eggs.
