Why are some people so negative about sunlight, don't they realise when they are burning coal, diesel, petrol they are just using stored sunlight, i.e. photosynthesis grew plants which animals ate, the whole lot got buried and we now use it as fuel. Why not cut out all the processes in between, and just use solar and wind power directly? Also mining/drilling for and transporting of liquid/solid fuels are not free, and all that equipment needs maintenance too. Renewable energy can be stored, either chemically, kinetically or thermally.Quote:

Robots and other devices used to treat and move fuel and waste, or by products become waste too.
Just too much waste, yes some of it may be short term low level stuff, but much of it is not.
Lucas Heights I remember as a kid has waste in under ground containment vessels stored off site not far away and what fun that could be if someone who wanted to make trouble.............I cannot see how it has been moved in the years since and the vessels were set up for the long term.
I am not against nuclear, but currently we dont have enough answers to the problems and the true running costs of the whole process from start to long term waste is never factored in.
The Thorum salt reactors, may be able to use lower quailty fuels and be a very safe design, but the waste from radio active pipes which have to replaced often is a big problem and the pipes and waste from thorum reactors emits high levels of radiation of very nasty types for Hundreds of years.
I dont profess to be a expert on this stuff, but my own investigation with a open eye to the whole picture.
No, it's totally true. Sunshine and wind ARE free. The energy inputs are free. Just a fact.Quote:

Technically, Coal is also renewable.

Appears to be a lot of experts at Aulro, so would appreciate them sharing their knowledge, as opposed ot opinions
Please nothing from The Guardian and the ilk, a source document if possible
