Green fridge

An idea to save power.

Why not have a split-refrigerator similar to split a/c?
Wouldn't fridges releasing the heat inside an air-conditioned(cooling, not heating) room would make it hard for the a/c? Or does keeping the fridge inside the a/c room reduces the power used by fridge?

Any way I don't live in an air-conditioned apartment and I believe energy can neither be created nor destroyed. But my fridge heats my apartment, which I don't like during summer. I would like it to dissipate heat outside my apartment. But during winder it can continue to serve as a room-heater.

GWUN

2030 AD. For the GWUN project sponsored by UN, 8700000 instances of the distributed GWUN clients are running busily on Linux Servers.

The global warming has already had a huge effect on the earth. And it seemed to be getting worse in the last 2 years. The poles were melting, sea-level rose, many countries have sub-merged in the sea and the life on earth was fast reducing.

The goal of the GWUN project is to compute the top reasons for global warming and the ways to protect life on earth. The scientists were eager to know the results. The situation was getting worser by the day. Huge corporations around the world sponsored more nodes for the project to speed it up. After busily computing for 27 months, the results were ready.

GWUN result: GWUN project machines were hosted at the Poles, to reduce the power consumption required for cooling those machines. Reducing power consumption was considered as a key factor to prevent global warming. But that released heat directly in the polar region of the earth. If the same amount of heat was released in an already warmer place, the earth's atmosphere would have managed to release/absorb the energy and the polar ice wouldn't have melted.

Beware of Glogle warming. Unknown preventive measures could be the real culprits.

Maths, Physics, Chemistry doubts

1. There was a fire-emergency drill yesterday in my office and now I have a doubt, "What is the coldest possible flame? And how much heat does it produce and its temperature?" The flame froma welding equipment is definitely hotter than the flame from candle, So how to have a 1 square inch of visible flame with least amount of energy released. Will it be the material that can be ignited at a lowest temperature? hmm may be the material the material that would continue to burn in the lowest temperature... so what it is? How much is the temp?
   

2. My roommate plays with Rubik cube a lot. And I saw an application that solves the rubik cube for your inputs. My question is what is the minimum no of faces required as input out of the total (9 x 6) 54 faces? Does the number change based on which faces?

3. What is the largest number possible with two 9s? A question on a poster in my office.
   

• 99

• 9^9 (But isnt using operator allowed? But exponent can be written without operators as superscript i.e., 9⁹)

• 9!^9! (But if you allow unary operators, I do not even need a second 9, i.e., ((9!)!)... == 9!!!!!!!!!!!!!
• I think 99 could be the answer without any opertators, but I would say it is a number with base-googol or may be base-infinity ;) [In base-infinity 99 would mean 9*infinity+9]
  

Please tell me whatever you think could be the answer.

Invention versus discovery

When I was a kid ( I am not a kid ), I used to think there is little value for discoveries as it is just unraveling what was already present and had a fascination for inventions. But of late, I feel that understanding the behavior or properties of everything is the root knowledge and inventions are just few applications of that knowledge.

p.s: Side-effect of reading "A Short History of Nearly Everything" by Bill Bryson. Do not worry, if my thoughts are wrong or rude, it keeps changing.
