When something is burnt, energy is only being converted - from chemical energy to heat energy. Even when someone talks about the (supposed) nuclear reaction inside earth's core, the mass lost really is converted into heat which is spread on to the mantle and perhaps the atmosphere, but definitely not radiated away. This increased energy would add to an equal amount of mass as lost by the (supposed) nuclear reaction if calculated using E=MC^2. The quantity (E+M*C^2) is conserved in a closed system.
The only real increase to this would be the energy from the sun, which would be approx 173 petawatt, of which 30% is reflected out (Albedo). Given that 25million kilowatt-hour is a gram, this would only contribute to an increase of just 4.8tons.
The "join" command in DOS could do this too... way back in the 90's...
Encryption is not going away. Any half good programmer can whip together a 3-DES or RSA routine together - why, many programming languages even have ready APIs for it.
Most governments go through this growing up phase with respect to encryption. Even US had export control norms for encryption software till they realised that directly controlling it is plain impossible (PGP was born outside the borders of the country due this very reason).
The Indian Law permits the Government to ask for the encryption key. Now, if someone asked for an encryption key to a SSL session, pray tell me how it can be retrieved... Some parts of the law are not very compatible with the technology that exists today. I do hope someone brings some sanity into this situation.
What India also needs to do is to have a due process to ask for encryption keys (warrant sounds fine to me), develop the ability to break encryption if the keys are not forthcoming (bruteforce the simple stuff - or get access to unencrypted material stored on the mail server), and importantly, learn who they should approach for the encryption keys (i.e, not the ISP).
Till the Government heeds solid technical advice on how to manage encryption, I am sure we will continue hearing such headlines.
In the GSM world, all you have to do is try your SIM on a different device, and you know if it is the network or the device. I prefer manufacturers who get users the features they need in their handsets, and telcos who look after networks. All artificial restrictions go away when you combine this with number portability.
There is no shortage of bundled and locked handsets and plans in the GSM world too. So subsidizing upfront purchase prices for the particular segment of buyers is very much possible, and happens quite a bit.
The CDMA platform may be more spectrum efficient, but IMHO, GSM wins out overall - from an user perspective at least.
