Fossil records tell us that about 250 million years ago, there wasn't a tree on Earth designed to survive in temperatures below freezing. They were all built for life in the tropics, where it's always warm, water is always liquid, and leaves are safe yearround without fear of frost. If you took a tropical tree whether ancient or modern and transported it to Siberia or Patagonia in winter, its water would freeze into sharpedged ice crystals, fatally puncturing the living cells in all of its leaves. The same thing that happens to lettuce and spinach.
When it freezes. Cold weather also means that water in the tree's plumbing system freezes, and dangerous bubbles form in the ice from air that was previously dissolved in the liquid water. The ice itself doesn't cause much harm, but when it thaws, the bubbles remain, which is a problem because the whole plumbing system relies on the intermolecular attraction of water molecules pulling each other upward against gravity. Air bubbles break the chain of molecules, essentially shutting off the flow of water. So to survive in cold weather, trees need to avoid two things bubbles in their pipes.
And direct damage to living cells due to ice crystals. They solved the first problem before ever leaving hot climates, because air bubbles are also a problem during drought. When plants work harder to get water from the soil, their waterconducting pipes can accidentally suck in tiny pockets of air from the surrounding tissue. To combat this, trees in the dry tropics developed skinnier pipes, which, thanks to the counterintuitive physics of bubbles, develop fewer bubble blockages than the highcapacity pipes of their wettropical cousins. So the plumbing of ancestral droughtadapted trees.
Was accidentally preadapted to the cold as well, well before they began to spread beyond the tropics. Upon arriving in cold places, trees then evolved two techniques they still use to avoid frozen leaves one is to fill living leaf cells with concentrated sugary sap, a biological version of antifreeze. Some trees mostly evergreen conifers like pines or spruce use solely this technique and keep their needlelike leaves unfrozen yearround with a super strong antifreeze. But other species, like maples and birches and larches, combine a less extreme level of sugar in their leaves with the practice of going leafless during the winter to avoid.
Foliar frostbite. These techniques are uniquely coldbeating adaptations well, they were, until descendants of leafdropping trees made it back to the dry tropics, where their strategy helps them deal with the extended seasonal droughts that occur in monsoonal climates. As far as we know, sugary sap remains the only adaptation that's only useful in cold places, which is why you have to come to the north if you want to tap into the sweet, sweet, antifreeze that might just help you survive the winter we call it maple syrup.

Art Inspired Solar Cells MichEpedia MconneX
The solar industry is very, very focused on improving efficiency and reducing the cost. Our attempt here with this research is to propose a new way of looking at these structures and saying, well, you can use existing materials and nothing really needs to change very much. You just shape them in different ways that gives you this benefit. Kirigami is a Japanese art that's related to origami where origami is really about folding of things and kirigami is about cutting things. A colleague of mine who is an artist, Matthew Shlian, he had some interesting.
New shapes and when you pulled on the sheet of paper the cuts would sort of begin to buckle and deform in a very controlled way and so I realized at that point that we could look at that structure as a hyperminiaturized version of solar trackers. Conventional solar tracking has been used for many, many years. The mechanism itself cost quite a bit of extra money. What people end up doing as they say, well, since the mechanisms gonna cost all this extra money. we might as well put a really big panel and then eventually you end up with.
Something that's really big and really heavy. When you think about putting this type of thing on a rooftop it's very very difficult and in most cases is just purely impossible. It was a fairly lengthy process because the things that you do in paper don't automatically translate to other materials and so I started talking to my colleague, Stephen Forrest, about using some of their very high efficiency gallium arsenide solar cells. They're pretty thin, less than 2 microns thick that's ten to fifty times thinner than the thickness of a human hair. What the new design allows us.
To do in contrast to conventional tracking is it basically allows us to work with the same form factor. It doesn't catch the wind, it doesn't weigh any more than a conventional solar panel might and the thing that it buys you is that you can use less semiconductor to gather the same amount of energy. A third less material to generate the same total amount of energy that you would otherwise. Which means that in turn that I could decrease the cost of installation because there are fewer panels to install but you do require little bit of extra area. When you.
Multiply it by the total number of solar installations it's kind of like a billion dollar value proposition potentially. I guess it looks simple enough, kind of like something that you could do on your kitchen table, things don't have to be complicated for them to work. If this can be shown to be quite reliable, then the net benefit could be quite big. V.O. These candies which are already pretty soft should be about 10 to 100 times stiffer than the silicone. So the material that we're working with in the lab is really really soft.
HOW TO KEEP CAR BATTERY HEALTHY AND CHARGED WITH SOLAR CELLS AUTO RAM TRUCK BAT POWER CHARGER
Hi everyone, this is geRAMicc85 and today i want to show you the new solar cells on my Dodge Ram 1500. I haven't been driving a lot with my truck over the last long and cold winter and I guess that's why my car battery died. Now, the battery was only 3.5 years old and I didn't want to replace it already but I had to. So I decided to do something to increase the lifespan of the new battery. I mounted tree 12 Volts epoxy resin solar cells onto the truck bed cover. I used silicone to glue them on securely. The cells are only.
A few millimeters think so that I can still open the Bak Flip cover without hitting the cells. I had to drill two small holes for the positive and negative wires. The wires run underneath the folding cover into the corner of the truck bed. The maximum output of the cells is 0.4 Amps. So whenever the battery is not fully charged or for example the radio is used with the engine off, the solar cells will fill the battery back up and provide it with a good maintenance charge. From the truck bed the wires run underneath.
The truck to the front into the engine compartment. I installed a charging regulator right next to the new battery which keeps the power from flowing backwords and also avoids overcharging the battery. The regulator has two LED indicators, one for charging and one for battery full. The green one is on right now showing that the battery is fully charged. The new battery that I've got is a 100 Amp hours car battery from Battery Industry Germany. It was the biggest battery that I could find that would fit into the spot. Thank you very much for.
