The real problem with energy is storing and transferring it. So, to your earlier point, it's no problem if it takes 2kWh of solar energy to be able to store and tranfer 1kWh because the Sun is unlimited (to us) energy. More specifically, that 2kWh may be available at the point of collection but everyone can't walk around with an acre of solar cells on their back. Back to ethanol and biodiesel, if you have solar powered combines to harvest the crops and used wind powered electricity to process it into fuel, who cares? You've now got a renewable and therefore infinite energy supply. The constraint there, however, is land. This is where pebble-bed nukes might come in handy. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:5:208786 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/5 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:5 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
