Then don't. Not nearly. I thought we weren't going to get conspiratorial. The varying magnetic field areas on Earth do affect compasses, but these variations are charted and aircraft & ship pilots are aware of them. Aircraft also use gyroscopic heading indicators and they are not affected by Earth's magnetic field. GPS receivers are also used for navigation and are unaffected by Earth's magnetic field. I ran across this paper in researching this post and I'll be reading it in its entirety ATA. By all means join me. >> Marine Magnetic Anomalies, Geomagnetic Field Reversals, and Motions of the Ocean Floor and Continents

I plan on having a beer or two when it warms up later today so I'll get back to you on this in good time(s). I will be cutting the strip with pinking shears some time before that however. . I knew I shouldn't have slept. Love the form, love the precision, love the paper. Coffee. Now there's a beverage! Here's the Möbius hole pinked. Here's a Möbius 3-Hole. 1 Surface, 4 Boundaries.

Got it anyway. I would answer no, but I'm no topologist. The idea just came to me on account of trying to keep up with Janus & imatfaal. I can't say I have seen it before, but that's not saying much either. I'm trying to cook up some variations, and in the mean time I think I can only say it's maybe possibly a non-orientable surface. Definitively a disorienting surface though. ajb? Got your ears on? Klein bottle @ wiki

Thank you. I love to feed people. Today I finished the Parsley & got 6 trays of Zucchini chips going; see below. Also it was bread baking day and I did 1 loaf with fresh Basil. So far I have done loaves with Rosemary & Thyme. Cilanto bread? The Blueberries sound great! Book says dip them in boiling water first to crack the skins before drying. The machine came with a solid tray liner for making fruit leather too. I have done 3 batches of Apple chips and they disappear in a hurry. Our Watermelon and Cantaloupe plants don't even have flowers yet so I may just try some from the market first. Book says they come out 'candy like'.

Aha! The [hasty] Möbius hole. One surface, two boundaries.

Nice! I am reminded of Escher's 1965 print Knots. (The work is copyright so I can only direct readers to a link.) >> Escher's Knots Of course his Möbius prints are perennial favorites. Mobius strip I Mobius strip II

Better than my first attempt! Thank you! High praise indeed. 42? .

'Mega-ocean' is a catchy headline term with no scientific value. The water is bound up in minerals, not sloshing around down there. New Evidence for Oceans of Water Deep in the Earth: Water bound in mantle rock alters our view of the Earths composition

Perhaps because she was not a scientist? You are mistaken Swan. Dekan is taking a poke at me for listing Ms. Nightingale in an earlier thread in which he was spouting sexist tripe. That is, Dekan is being sarcastic. Go figure. Here's my post on the subject. >> post #20: Why women are so extremely emotional?

This year I chipped in and bought a food dehydrator to preserve some of the produce. From the garden so far I have done Cilantro, even though many sources said it loses its flavor. It did take 5 days to dry, but it was worth the effort as contrary to what I read it remains flavorful. Part of the trick [apparently] is to not break it up after drying until ready to use as the added surface area of the breakage speeds oxidation. This week I'm trying Parsley. See image below. As soon as it's done I'm going to try Zucchini chips. The manual says wash, slice to 3/8", and dry until crispy for dip chips, but blanch before drying if I plan to reconstitute it for breads etcetera. What's growing in your garden?

Most of the corn production in the US is fed to animals; 80% by this source. >> Major Crops Grown in the United States They further note we only consume 12% of our production some of which is as high fructose corn syrup and we on average consume only 25 pounds annually. Read about the nutrients in corn in a variety of forms here: >> corn As to the gluten issue, it is an urban myth promoted for profit that gluten is bad for people. It's only a problem for people who have celiac disease or are sensitive to gluten, and such people are a small minority. What to know about celiac disease, gluten sensitivity, and gluten-free diets. As to the OP, yes we are [in general] as well adapted in N. America as anywhere else we have habituated. I say generally because if you live in a polluted area anywhere then the effects will be similar. If you think you are unhealthy, see a doctor.

Good thinkin' Lincoln. I would just say that stupid laws never saw our homes as an impediment. I ride a tricycle and gave some thought to putting an electric motor on it, but I don't ride it enough to make it worth the trouble and expense. It might be nice on some steep hills, but otherwise it would be robbing me of the exercise benefit. Appension: Then there is the novel idea of doing a web search for 'solar powered bike'.

Nothing wrong in my opinion. Here's something from a famous philosopher to help alleviate your fears. In Praise of Idleness By Bertrand Russell

A couple weeks ago I spotted some aphids on a potted plant and as they apparently ruined last year's Brussels sprouts I suggested we try some Ladybugs. [Ladybirds for you Brits?] Anyway, it was $10 US for 1500 and we released them over 4 or 5 days. As there were no aphids in the garden yet most seem to have flown off. Then a couple days ago I found aphids in patches on one of this year's Brussels sprouts so I just sprayed them off with the hose. This seems to have worked as today I see none. Anyone else have aphid probs? Will just finish up with yesterday's pea harvest. Modest but ohhhh so tasty.

Well, it doesn't work like that. If it did then that's how engineers would build PV systems.

Yes, it's the area but specific to the output of that area. No, it's not a workable idea but kewl looking droid there. Anyway, the OP seems to be asking if solar PV panels could power a bike directly and the answer is [theoretically] yes. In all practicality however, the answer is no. I did some checking and found a bike motor kit. [$1,500!! :0 ] bike motor kit The motor is rated 36V, 350 watts/700 watts peak. I suspect that peak is getting it started so you need panels giving at least that. You would need 36V panels because most panels have diodes to protect from bass ackward connections and you can only connect them in parallel and not series. So we'll take Ed's panels and presume 36V & 60 watt. 700/60=11.66 panels. Call it twelve panels @ 20 lbs each and you have 240 lbs & 72ft2 of surface. If you ride into some shade or turn so the panels don't face the Sun, so long power. So not really practical.

That's not quite right either. Your total area would be 6.25ft2. Advert says 44 5/8" x 19 1/4": 44.625 X 19.25 = 859.03125in2 divided by 144in2 per ft2 = 5.96ft2. Call it 6ft2, so 10watts per ft2. That's overestimating a bit too because the frame is part of the total area and produces no juices. Nevertheless, it is twice the output per ft2 of my current panel so I am indeed behind the times. [My 15watt panel is over 10 years old.] And $500!? I think mine was $120 back in the day. Egat Brain. PS Keep in mind that a high output panel shouldn't be connected directly to the battery as it will 'overcharge'; you will need a charge controller in the circuit.

I believe the limit on a quick question is not number of words, but number of posts. A quick question should be one that can be stated in one post and answered in another. The alternative is a question that one asks in a thread and has many responses, possibly by several people. If someone asks a question in this thread that takes too many posts, a moderator can move it to another thread, one created for the question. Thus, one may ask any question in this, the Quick Question thread, even if it takes several posts to answer. Just don't create work for the moderators moving posts on purpose; try to keep questions in this thread that can be answered by one post. It was a joke Ed.

Got a reference for that? If true, I'm behind the times because my 1ft X 3ft panel is only 15 watts. Maybe the panel could double as a sail!

G'donya for the effort. Every little bit helps.

We definitely considered the twelve bore, but we're a little too suburban for that to go over well. Plus you have to see it to shoot it and I had better things to do than sit & watch for it. I did happen to see it pushing up dirt once and tried to pitch fork it, but I had the tine curve the wrong way & missed it. Raspberries, peas, and strawberries are mostly done, but the blueberries are on the table now. Also enjoying dill, basil, thyme, cilantro, rhubarb, radishes, spinach, and parsley. The broccoli is mostly done but we're letting it go to flower & seed as I recently read that broccoli sprouts are tasty and healthy. Rats!! So the rat(s) showed up that we first noticed a couple months or more ago, feeding on birdseed that fell to the ground from the feeder. Got rid of the feeder and didn't see any rats for a while. Then we started seeing just 1, which I now think was mom. We put out poison and traps. They didn't touch the poison and ate the bait from the traps without setting them off, or occasionaly set a trap off but were not caught. Last week Son'o spotted mom napping on top of the compost pile and shot her. A few days later I was watering down the compost pile and out came 4 young ones. Last night I shot the last 2 of 6 young and we thought we had it made. (I put a floodlight right on the compost pile and waited. ) Sooooo, our tomatoes are all still green so I just ran to market to get tomatoes, some mushrooms and garlic for ratatouille ala Acme, and when I get back Son'o tells me we got rat dad. I didn't know if rat dads hung around with the fam, but this one apparently did. Anyway, it was killed by a modified rat trap, but wasn't caught in it! WTF!? Since they were eating the bait without setting off the trap, I made a box that the trap just fit in, added a wood platform to the trigger and put the bait in the back of the box & not on the trigger. See image below. (I'll spare you the dead rat pic. ) So off to the garden now to harvest some basil & thyme for the ratatouille and then to the kitchen for some cookin'. Aint suburban gardening fun! Here's the ratatouille à la Acme before baking. Made with 70% home-grown suburban farm produce, this authentic French cuisine is also made with fresh rat; none of that canned rat for me boy!

It's kinda one of those 'it depends' questions. Start with an electric bike and a 12volt deep cell battery. The battery is rated in amp hours and you only get about 80% of the rated value. So if you have a 100 amp/hour battery and your motor is using [guessing] 5 amps, then the battery will be drained in 16 hours. Photovoltaic panels are rated in amps [amps = watts/volts] so if you have a 1 amp panel [about 15 watts] it would take about 80 hours of good sun to charge your battery back to full. You can calculate differeing battery ratings, number of panels, and amp ratings of motors to suit your specifics using my examples. Have fun!
