Renault on top of the engine game as always. Is that a huge intercooler on the left side of the engine? Will they allow intercooling in the new rules? And what's the deal with this new technology they've spoken of that absorbs waste heat from the engine?

Yes it is an intercooler on the left side that is when facing the engine from the back of the car, intercoolers are allowed as they are a must, the Renault picture shows the MGU-H placed in front of the turbo and to the left (so it uses a gearbox) and not in between the turbo impellors.
The term heat recovery from brakes and exhaust gasses (ERS) can easily mislead/confuse the not so technically minded a simple explanation might be of help.
KERS makes use of one MGU-K (kinetic), this MGU (motor/generator) is connected to the crankshaft via a tiny gearbox and clutch it's RPM is twice that of the engine , it is switched on (rotated) via the clutch (1) when the driver hits the brakes (acting as a generator) to charge the batteries, or it is switched on (rotated) via the clutch (2) when the driver presses the KERS button (acting as a motor) to add power to the engine.
The 2014 ERS system will have an MGU-K (kinetic) of twice the power output, it will also have another MGU-H (heat) fitted

Continued, (connected) to the turbo shaft, this MGU-H (heat) will act as a motor when rotating (spooling up) the turbo, or as a generator when rotated by the turbo shaft when it can either charge the batteries or put additional power into the MGU-K (kinetic).
Now for some more details, the cars will be allocated 100kg of fuel for a race.
The engine will have a fuel flow restriction of maximum 100kg/hr.
The above means that full engine power will not be able to be used at will.
NOTE, by full engine power is meant (as restricted by full permitted fuel flow).

sunny. the engine noise is not too bad. yes shriller than the vv8, but nowhere near the shrillness of the engines we adore V and flat 12s. the noise is also less shrill than the previous turbos, so we will get used to them fairly quickly. remember the outcry when they went from v10 to v8? now nobody wants to go to v6!

actual engine looks quite small, it is just the ancilliaries that make it look big. await some clever repackaging by newey!

Ptolemy. they will be recovering heat from the engine to create steam,, which will be used to drive a steam turbine to add power to the rear wheels. :D :D

Will they be blowing up the same as the first ones (that Alain Prost etc used) did, sadly I dont think so (of course they'll be 'restricted') so the show more or less goes on.

There are no restrictions on boost simply because there is no need too.
The fuel flow restriction added to the mandated fuel load for the race restricts a lot of parameters, both engineering wise and management wise.
Richard, I cannot as yet have an opinion about the engine sound simply as I haven't yet heard one running.
