How to get a 100% efficient Light Source with Brilliance?
It is known by Physics students that the internal combustion engine converts Static, stored petrol-energy into movement in a vehicle, with 66% loss of energy, and 33% useful Work done. Same way, a Solar Panel takes energy from the sun, but 66% is lost, and 33% is converted into electricity for light in the rooms, charging an accumulator storage cell, etc. But, a Solar water heater converts more than 80% to 90% of the Sun’s heat energy into hot water for domestic use. It consists of black copper tubes kept facing the direct sunlight, under a glass pane, which acts as an insulator when the sun is blocked by clouds or at sunset. The tubes have water, which circulates slowly, as it becomes hot, up to 72 degrees Centigrade, and the hot water is stored in the insulated storage tank. What is the common light source with 100% efficiency. Name a few.
My dear loo…. the australians have been using it, and India can at least copy them, before we are pasted on their dailies as primitive people in the headlines.
Ivan, I am just asking for a 100% efficient light source. Even the first cave dweller made a window to get 100% light from the Sun. Today, there are great trends all over the world, and why there are no such steps reported in india, EFY, etc. when we are asked to be environment friendly today?
To help you further answer this: Note that an AA battery powers a mechanical clock for 365 days to provide time on the clock face, but an LED based display will provide the time for only 10 days or less, due to the large amount of current it uses. So, we have to save this current and become green.
So, since the window is a 100% source of Brilliance into the room, we have 1. Curtains and drapes. 2. Special silicates that are transparent or opaque at critical temperatures. 3. Fluid oils that fill the gap between two glass panes to cut off visible and infrared light or let it in 4. and in electronics, at present in California, research is being done on electronic coatings on the glass panes for the same objective.
The LED that many talk about is expensive, and always second to CFL lighting for domestic lighting. A Philips tornado CFL 20 Watt light source at rupees 200 is a standard domenstic light source.
What is your question again? I mean, I appreciate the information, but what is it that you want to know? It seems that you are comparing apples and oranges.
The closes to 100 percent efficient source is an LED, which produces a photon per electron injected in the junction. There is, however, the problem of light extraction due to total internal reflection in the semiconductor itself. This is, light is produced with almost 100 efficiency, but only some fraction of that would make it out of the semiconductor.
I used to do research on that during my PhD and we proposed a method to extract light in a more efficient manner, but we didn’t come anywhere near close to 100 percent extraction. Maximum was, I think, about 50% extraction.

Cloud Storage/Back-up Tutorial – Part 1
I’ve decided to do an in-depth series discussing and showing my back-up/ remote storage system. It’s fairly complex in itself since changes are synced to offline copies of the cloud, some files are left on the cloud, my MobileMe iDisk comes into play, Time Machine and some third party software is used, and there is some long-term back-up done using encryption.
Take a look at part 1, which simply shows you the hardware and gives in introduction into the concept. Part 2 will feature the syncing aspect, part 3 will deal with Time Machine and back-ups and part 4 will handle long-term, high-security back-up.

My Short Story, just for fun : ) Any comments appreciated!!?
I just found this story that was a result of an all-nighter i pulled my freshman year of high school : ) haha Reactions, anyone?
What Happened on Tempest Point
Outside the luxurious Seaview Hotel, the tide crashed on to the dunes of Tempest Point. Tourists crowded the areas of the beach that weren’t ridden with jagged Maine granite. The sight- seers scurried in and out of the expansive brick resort like ants in gaudy swimsuits, rushing to fetch towels, or sunglasses, or more tanning lotion.
An unadorned window on the bottom floor of the Seaview was flung open to welcome the salt laden breeze. Behind it, standing at an immense sink filled with dirty dishes, was a girl of about fourteen. She had long, dark, hair and distant eyes that seemed to reflect the dark blue- gray of the Maine ocean. The girl stared at the small children splashing in the shore while their parents lazed on blankets, covered in baby oil. <ital>How can those mothers and fathers let their children near the water?<end italics> There had been a time when the girl had loved the wild Atlantic. She had felt like the luckiest person in the world, to have it waiting at her front door. <ital>That was before I knew what was hidden beneath the surface. Unbridled rage, waiting for the right moment to take, and never to return.<italics end> Gray clouds seemed to obscure her eyes as she remembered the terrible night.
“Marina!” an annoyed voice called. Marina, the girl at the sink, flinched as she heard her name, a constant reminder of the sea. “What are you doing, idling the afternoon away? Wash the dishes! The software engineers will be here in one hour for their company convention!” The hotel manager turned on his heel and stalked out through the swinging doors of the kitchens. A short man in his mid- fifties, with salt and pepper hair, Walter Galvin had been Marina’s mother’s second cousin three times removed. Or was it third cousin twice removed?
Marina scowled at her “Uncle Walt’s” retreating back. Turning to the open window, swollen from humidity and sticky from salt, she wrenched it shut. Filling the sink with hot water and suds, Marina began to work.
The Seaview often played host to companies or other groups holding conferences or meetings. Marina hoped the engineers weren’t picky and were quiet.
By the time Marina had washed enough dishes to serve an army, DigiTech software vans were pulling into the parking lot behind the hotel. She watched computer engineers awkwardly climb out of the vans in their suits and ties. Hanging her apron on a peg, she straightened her boring regulation waitress outfit: white blouse with a blue knee length skirt.
Half an hour later, it was dinnertime. When Marina entered the corporate dining room to take beverage orders, she was greeted by a sea of combovers and glasses. After endless requests for V-8 and prune juice, followed by the main course and dessert, she was exhausted. After helping to bus the tables, Marina climbed a narrow back staircase to her room.
Her room was on the top floor, floor three. It used to be a storage room. Its one small window viewed a parking lot. When Marina had moved into the Seaview after the terrible night, her Uncle Walter had offered her a large room with a bay window overlooking the ocean. But the girl wanted no reminder of the force that had changed her life forever.
That night, she dreamt of a turbulent sea and one tiny boat, drifting and trying to stay afloat.
July 7th
While the guests were at breakfast, Marina joined the housekeepers in making the beds ant putting fresh towels in all of the rooms. When she knocked on the door of the last room on her assigned floor, a man talking on a cell phone answered. One of the few engineers without glasses, his DigiTech nametag read, “Hi! My name is Marc.” Mike- Alpha- Romeo- Charlie Marina thought automatically. But no. She couldn’t think about the radio codes any more. She had to never let those memories surface again.
Marc waved her inside. Covering the mouthpiece of the phone, he whispered. “Sorry. I’ll finish the call on the porch.” The man walked out onto the small deck outside his room, still talking on the small phone. As Marina made the bed, fragments of conversation floated through the bay window. “isn’t working…won’t tell…have to..daughter…Seaview…”
When Marina heard that word, daughter, she blinked back tears. It wasn’t that long ago that she had been a daughter. Nine months, though it felt like an eternity. Marina had been a daughter for thirteen and a half years.
Marina’s mother, Mara Chandler, married Jonah Taylor in 1990. A month before their first child, Marina, was to be born, Jonah left his wife. “I should have known he was no good.” Mara would later joke to her daughter. “After all, he was a Jonah- bad luck.” Jonah Taylor never tried to contact his wife or child, but Marina didn’t care. She and her mom lived in a small bu
. She and her mom lived in a small but beautiful house by the shore. They were perfectly happy. Mara, a marine biologist, would sometimes take Marina out on their small motor boat, the Rover. Mara was interested in tracking whale’s migratory patterns.
Then, one September afternoon, Marina had come home from school to find that her mom was not at home. This wasn’t unusual; Mara’s work often kept her away all day. Marina knew she was boating with a friend, Ian Collier. He was another marine biologist. Marina still wasn’t worried when her mom wasn’t home by nine. When Mara was excited about a new find, she often lost track of time. She’s probably at Ian’s house, graphing today’s data on his computer. Marina went to bed, wondering if her mom had found something unusual on the new sonar program that she had invented
However, at 2am, Marina was awakened by a deafening peal of thunder. Looking out the window, Marina saw that the rain was coming down in icy torrents. The sea was a
The sea was a choppy battle. Walking through the house, she realized her mom still hadn’t arrived back at home. She couldn’t still be at Ian’s, could she? Why hadn’t she called? Knowing that it was an ungodly hour to be calling someone, she picked up the phone and dialed Ian Collier.
No answer.
Sitting down to think about what to do, Marina drifted back to sleep.
The next morning, she was woken by the sound of her uncle’s quick footsteps through the front door. His face was drawn and gray. Walter laid a hand on Marina’s shoulder. “Marina…” he began softly. “There’s been an accident.”
The “Storm of the Century,” as everyone called it, had smashed the Rover against a jetty.Blood was found on the jagged rocks, and Ian’s body, dismembered by propeller blades, was discovered nearby. Mara’s body was never found.
Marina swallowed a sob and wiped a tear from her cheek. Staring at the tiled floor, she tried to remember why she was in a bathroom. Realizing she was supposed to be
Staring at the tiled floor, she tried to remember why she was in a bathroom. Realizing she was supposed to be changing towels, she slid a fresh cloth stamped with SEAVIEW onto the rack. She heard Marc, the engineer, come back from the porch. He was still talking on the phone. Marina heard his voice growing louder as he approached the bathroom. Finishing the chores quickly, in case he thought she was wasting time, Marina moved toward the doorway.
Marc laughed into the phone, a humorless sound.” and you’ll never guess who is cleaning my room at the Seaview…Yeah. Couldn’t be easier, could it? Just the girl we wanted to see.” A huge hand was suddenly clapped over Marina’s mouth She tried to scream, but was silenced by a blow to her head
When Marina came to, she knew instantly that she was in a boat. Fighting the panic that threatened to overwhelm her, she took a deep, steadying breath. She seemed to be in some sort of cargo hold. Was there any hope of escape? Who had done this?
It all came back to her…Marc’s mysterious phone calls…the kidnapping obviously hadn’t been impulsive- someone had planned this out. But why would anyone kidnap her? Ransom? Her only relation, Uncle Walter, wasn’t especially wealthy. But even so, why bring her all the way out onto the ocean? Why not hide her somewhere else?
Abruptly, light flooded the hold as a door in the ceiling was opened. Someone jumped to the floor. Marina shrank into a corner. Kidnappers? “Marina!” a woman shouted.
Marina froze. She’d know that voice anywhere…but how could this possibly be true? “Mom!” she screamed.
After a tearful reunion, some questions began to be answered. There had been a freak storm, but Mara should have been able to get home. She was an experienced sailor. However, she explained, she and Ian were on their way back to shore when a larger boat had blocked their path. Mara and Ian were held at gunpoint and forced off of the Rover and onto the huge tugboat. They watched as the
They watched as the stage was set for their deaths. The tug pulled the Rover onto the jetty, where it was smashed by the fierce tides.
“But- Ian..” Marina stuttered. She couldn’t believe her mom was alive. It was all so unreal. “They found his body.”
Mara sighed, her eyes overbright. “Yes, they had no use for Ian. Marc- or whatever his real name is- and his friends slit Ian’s throat- and then-“Mara’s voice faltered. “Well, I guess Marc saw Raiders of the Lost Ark one too many times. They turned on the propellers and-” Marina’s mom broke off.
“But why did they want you?”
“Remember that sonar program I invented? Well, at the tine, I thought nothing of it. I thought of a way I could locate pods of whales more easily, and made a few adjustments. Marc apparently thinks that if he can find the key to working the software, he can sell it a become a millionaire”
“So that’s why they took you? To get information?”
“Yes. I haven’t told them what they need to know, if I thought
they would let me go after I disclosed the key, I would have done it in an instant the money means nothing to me. But the kidnappers have already shown that they don’t mind murdering innocent people, and I’m too big a risk to set free. So they did the thing that could make me talk- they took you. I think they’ll use you as blackmail. I- I don’t know what to. I’m trapped. If I reveal the pass code, they’ll get rid of us afterwards. If I don’t tell, they’ll hurt you.”
“Mom!” Gasped Marina. “We’ve got to get out of here! Where are we?”
“From what I can tell, we’re pretty far out. Almost in international waters.”
“Do they let us on deck?”
“Most of the time. It’s not like we can go anywhere. But look here.” Striding to the wall of the hold, Mara moved aside a few spare planks that were leaning in the wall. A small, round, porthole was revealed. It wasn’t big enough to climb out of, but it was something.
“Have any other ships passed us??” Marina asked.
“None
far.” said Mara. “But if we are nearing international borders, there should be Coast Guard up ahead.”
An hour later, Mara and her daughter saw a Coast Guard ship ahead. Mara Chandler handed her daughter the watch. Focusing the watch crystal on the sun, Marina moved her hand back and forth in front of the beam of light. Why could she never remember SOS – was it dashes and then dots, or the other way around? Once you got started, did it even matter? She signaled frantically. Nothing.
“Please…” Marina whispered as her mom took over the signaling. “Please look…” There was still no reaction from the Coast Guard.
Marina suddenly had another idea. Climbing onto the deck, she crept across the bumpy metal floor. She had reached the flagpole. Praying no one would notice, she removed all forms or identification from the thick lanyard. Without permit or license flags, would the officers notice an unmarked ship? Stealing back down to the hold, the Chandlers watched the Coast
Guard draw nearer and nearer…
August 28th
Now that the trial was finally over, Ms. Chandler and Marina could return to their old cottage. Their testimony had sent Marc (whose real name was Clarence) to prison for a very long time. Marina looked forward to seeing him pick up trash in an orange jumpsuit. Ms. Chandler patented her program, and, while she didn’t quite become a millionaire, no one complained. It was enough to buy a new and better equipped research boat. They named it the Semper Paratus in honor of the Coast Guard that had saved their lives.
If you wrote your story when you were a Freshman in high school, I think that it’s really quite good. It’s well-written, literate, grammatically correct, punctuated properly, with no glaring errors in spelling. Additionally, for a short story it is intriguing, exciting, and, as you have created the plot, believable. You appear to have knowledge of your subject. When I read, I always notice discrepancies or inconsistencies in the plot which will cause me to question its rationale or distract me from enjoying it; although your story might possibly have been unrealistic, you have written it so that it seems plausible. I don’t know what your aspirations are for it, but I do think that it is better by far than most of what I’ve read posted here.
