  I agree - Plug-in Chemical storage is way simpler

  IF we could just divert that money to rapidly commercialising things like 3rd generation firefly batteries, and other new battery technologies that are already here, then we'd have decent dense storage for our hybrids and plug-in hybrids on massive scale.

  Coal and Sun - small scale power towers

  Ok That's ridiculous -- you don't close down coal railways -- you give them a rebirth as goods or passenger railway corridors (very fast trains etc.)

  Just to abandon a railway without a proper assesment of reuse of that route would be ridiculous.

  Now carrying coal -- well that has to end ASAP.

  This is a bigger deal in Australia where I come from, where we are the world's biggest exporter of coal.

  Though 2/3 of it by value is for coking steal making (metallurgic coal)  This requires biochar and high temperature industrial solar thermal (Dishes or power towers) to replace the heat requirement.

  Same goes for concrete need dishes to provide teh 1000 degree + temperatures required to cook up the cement mix

  This company aora -- formerly edig solar.. is doing small scale from 100kw electrical upto 5MW

  For interviews with all the Solar Developers

  we run a bi-weekly radio program devoted to Climate Change Science and Solutions and the need to goto 100% renewable Energy straight away.  Hopefully Joseph Romm realises this and adjusts the targets he is advocating accordingly.

  388ppm --> Too much carbon in the atmosphere

  350ppm --> Still too much for a safe arctic.

  300ppm --> Around where we need to be with atmsopheric carbon stabilisation.On Biggest California utility contracts for world's biggest solar power deal posted 9 months, 1 week ago 23 Responses

  Molten Salt Tech - Solar Thermal here and now

  
  Andasol 1, and Andasol 2, are 2x 50MW Solar Thermal plants using conventional Troughs
  http://en.wikipedia.org/wiki/Andasol_1
  http://www.renewableenergyworld.com/rea/news/article/2008 ...

  Andalucia Spain - with 7.5 hours of Molten Salt Storage at Full Capacity ie 50MW constant for 7.5 hours after sun down.

  Due to the structure of the Feed in tarriff and the limit on plant size at 50MW electrical almost all solar plants being built in Spain will now have significant storage, in order to maximise income, leveraging the feed-in tarriff.

  Solar Tres by Torresol is under construction in Spain.  It is a 17MW capacity Solar Power Tower (Distribution Power Tower - with Heliostat Mirror Field)  It will have a 74% capacity factor ie run the equivalent of 74% of the time over 365 days of the year or be generating around 18 hours per day every day of the year.
  Fuentes de Andalucia, near Seville,

  This plant has broken ground, and construction has begun, it will be complete at the end of 2010.

  Solar Reserve which has come out of the US Military / NASA industrial complex is ready to build the same kind of power towers with storage

  Lloyd Energy Stroage uses a Novel system with a Graphite block mounted on top of a power tower.

  Wizard Power is commercialising 500 square metre low cost dishes developed by Australian National University that are using Ammonia Thermochemical storage.

  vakibs -- all ideology

  Vakibs - My father is a Nuclear Physicist

  Like you I'm just a computer engineer so I have to refer to the experts.

  Breeder reactors aren't off the ground.  The best India with all its massive resources claims it can do is 300MW of capacity by 2020.  I'm sorry we don't have that long -- see Hansen et al.

  Diverting a regular proportion of our mining, materials industrial capacity will give us a solar thermal with storage based infrastructure backing up wind power and rooftop PV.

  You have not answered the questions on density.. Nuclear is so diffuse it's pollution has to be spread across 1000s of kilometres of Australian country side.  

  Where are your figures.  Show us the numbers.. How many square kilometres including all the mining and the chemicals for scrubbing and their mining.

  Steel and Glass are relatively simple to make and process.

  Not so for all the inputs required to process uranium and scrub waste products etc.

  Please show the numbers or get off the bandwagonOn So how much do renewables cost anyway? posted 1 year, 2 months ago 30 Responses
