I don't suppose it would be at all useful to you to have a Science Teacher around the place, would it? smiley - winkeye

^_^ Why yes, it would be useful.

Any questions, ask away.

I've just taught this topic to my Year 10 class, so it's all fresh in my brain. smiley - ok

Anything at all. And then I can add this threasd to my bibliography. smiley - biggrin It will be a LONG bibliography.

Hey! You're not getting Science lessons for free, you know. smiley - tongueout

I will gladly answer questions or push some more information at you on a them, though. smiley - smiley

Um... Information about biomass as an energy source?

Er...not much really.

The general concept is to use dried manure or peat as a substitute for fossil fuels in small-scale power stations. The big issue is that Biomass does not have a lot of stored energy, therefore produces less heat than coal or even wood. It also kicks out a lot of greenhouse gases, particuly CO2, SO2 and water.

One for left-wing beardies only, really.

Hmm... So is it renewable or not?

Er...more or less. As you say, it is a bit borderline.

Er- a note on biomass- what about biodiesel?

Mu Beta

Still here. smiley - ok

It's OK to say that geothermal heat is that which emanates from the centre of the Earth. How about adding that the heat originates from radioactive decay of elements in the Earth's core?

Then there are many problems involved with extracting the heat - the drilling technology is expensive; there are thermal gradients on the way up, which means a lot of energy is wasted and, of course, the heat source is not as intense as burning stuff.

Other than that, it is a reasonably good idea.

It does? I didn't know that. Thanks! smiley - ok

Biodiesel? What's that?

This is the idea of running cars from vegetable oil. OK if you're car's designed for it; does a good job of screwing up a diesel engine though.

Ah. I've heard of that... Running a car on vegetable oil=smiley - weird

Don't forget the production of ethanol from sugar and grains. Used extensively in Brazil to run their cars....smiley - peacedove

I have the big issue, that EandC has already mentioned, that crops are not necessarily renewable resources.
