Technology / Re: Ethanol fuel is the way to go

No, for the same reason that solar is a non starter, because the land is too valuable to use producing fuel. If we could grow our fuel we could make methanol or wood alcohol, but grain and the straw that comes with it are too valuable. As an example, you can make fuel from animal slurry, but farmers value it too highly to sell for the price people will pay.

This will mean that ethanol is more expensive to run yet it sells at a far cheaper price.

The sale price is what the petrol station advertises (per litre).
The running costs are borne by the car owner (how many litres they need for a given trip).
The two are not contradictory, but they do tend to cancel out for both the car owner and petrol station operator...

New Theories / Re: If there was one Big Bang event, why not multiple big bangs?

« on: 04/10/2021 17:06:02 »

What I find more entertaining than the ants are the squirrels that don't abide by the rule that the seed I put in the bird feeders is for the birds. From dawn to dusk, as long as I keep seed in the feeders, there is a steady stream of birds and squirrels at the feeders hanging outside my windows. And there is constant competition among the four or five squirrels that are almost always hanging around there. They love to cling to the feeders by their hind legs and eat until they get knocked off their perch by other squirrels or incoming birds.


My bet is that this activity is universal, meaning that in a universe full of hospitable planets, of which some percentage are teaming with life, there are squirrels, or their living equivalents, jostling for the available food, all of the time in our multiple Big Bang universe.

Physics, Astronomy & Cosmology / Re: What is TIME?

« on: 03/10/2021 19:40:20 »

The definition Alan quoted above works quite nice for time as an integral part of spacetime, and it works for other interpretations as well. So it is a far better definition

Thanks,I missed that.

Other events are independent or subject to less constant conditions but their sequence can be located on a time line established on the basis of constant-dependent events

Could I ask if you have any examples?

I had been  wondering whether all pairs of events are connected,either from A to B or from B to A depending on circumstance(eg I cannot influence my mother's early life but she could (and did?) mine-as a specific example of what I was assuming would be the general case)

To clarify the specific case above, if she took ,say 5 minutes extra to do the shopping on a day before I was born ,I am saying that that extra 5 minutes would have changed the course of the universe and my  life (and all others ) would be included in that changed universe.

So her shopping and my , say fit of coughing would be connected events  but only in the direction of her to me .

So to my mind all events in the universe are connected but sometimes only  in one direction.

It has not got to mix perfectly

Do you know what actually happens when you put alcohol in a hydrocarbon?
I just took a picture.
This is 2.5 ml of >95% alcohol in 25 ml of white spirit.

Ethanol is slightly less energy dense than traditional gasoline (so you have to fill up more often).
- Ethanol still produces carbon dioxide, but since it is usually produced from growing plants, it contributes less carbon dioxide than burning fossil carbon.
- Most countries sell a mix of ethanol and gasoline as an option (not a mix of ethanol and water).
- Brazil has taken ethanol further than most countries, as ethanol can be produced from locally-grown sugar cane. Motor vehicles can sense the ethanol content in the fuel, and adjust the engine parameters to get the most from the fuel.
- Of course, large-scale cultivation of a sugarcane monoculture displaces a richer biodiversity, so it has some downsides, too.

Plant Sciences, Zoology & Evolution / Re: Why is chocolate bad for dogs (& cats &...)?

« on: 01/10/2021 22:33:14 »

As evan has already said, theobromine is just a stimulant in the same family as caffeine. Dogs livers don't break it down quickly and they get overstimulated and overheat and can have convulsions. They can eat a little bit, but best not to give them a taste for it.

Fun fact: When I had swine flu I had an awful cough. I ate half of a dark chocolate bar, and my cough STOPPED for about 2 hours or so. Theobromine suppresses the vagus nerve which causes coughing. Doesn't cure the cough in any way, but you stop coughing for a bit.

General Science / Re: Can someone healthily raise a cat or dog with meatless food?

« on: 01/10/2021 22:19:28 »

No, cats can eat an entire non meat diet if they have to. But there are issues with things that are normally missing from plant diets (e.g. taurine, vitamin D, etc. etc.) and things that are normally in plant diets in too high quantities (carbohydrates).

But these are not show-stoppers, taurine is routinely synthesised (it's in Red Bull) and is already added to cat food. Things like carbohydrates aren't in all plant foods. But they are in game meat, because muscles and livers contain glycogen.

Basically, cats are mammals, and their dietary requirements aren't THAT dissimilar to human ones, but the proportions they've evolved to need are different.

The issue is not so much that it can't be done, it CAN be done, at a cost. The other issue is that we don't necessarily know the exact nutritional requirements cats need to stay healthy.

General Science / Re: Can someone healthily raise a cat or dog with meatless food?

« on: 01/10/2021 21:40:03 »

A dog can theoretically be fed nothing but plant-based foods. To remain reasonably healthy they'd need synthetic supplements to supply nutrients unavailable in plants.
Cats on the other hand are true carnivores and must eat meat to remain healthy. There are places that will bring criminal charges (cruelty) to those withholding mean from feline pets. Lab-grown meat will do the job, if your reasons for the weird diet come from an aversion to the slaughter of food animals.

This is a huge dilemma for vegetarians/vegans. All the nutrients and what-not can be artificially produced, but some still think it will slowly kill their pet somehow as if there is a magical component in meat that cannot be replicated.

I am quite interested in the micro world to I am looking for what is called a water bear to view and sperm is quite good to see if you have a male donor at hand a dog will do or even one's self. You do need a microscope of course with at least 200x magnification.

There is no end to the amazing things in the micro world. But even in the macro world I am always discovering new and interesting things as I observe Nature on my walks. Recently I saw a team of ants dragging a dead grasshopper across the drive. I figure they would run into trouble fitting it in when they get it home, lol.

« on: 01/10/2021 16:05:19 »

Hi J_T!
Thanks for your concern.
😊
🙏

Nope!
The local dietician nor the family physician showed much interest, except for to advice to cut down on salt.

Even Googling did Not help.
There's soo much bout sugar & diabetes, n soo less bout salt.
😏
(Similar suggestions appeared online, sayin cut down on salt n have a balanced diet)

I'm still stuck with the salt thou.
I think or i guess it's salt deficiency.

If i cut off salt completely, my b.p. will plummet fo sure!
🤭
Prapz my body is smarter than me, n chooses to override my mind.

Ps - I did read that a low b.p. is riskier than high b.p...but that did Not make sense.
Both can lead to loss of life.
