What other energy technology "never can fail" ?
Anything packing energy is dangerous. Petroleum refineries catch on fire and explode with some regularity, as do underground gas lines. Electric lines spark fires and heat the atmosphere, and people do get electrocuted on a fairly regular basis. Dams collapse, windmills disintegrate -- nothing is perfectly safe, and the more energy it handles the harder it is to minimize the danger. That just a fact of life, for all energy technologies.
Don't let the perfect be the enemy of the good -- and certainly not the best candidate we have at present.
Kick in to the DU tip jar?
This week we're running a special pop-up mini fund drive. From Monday through Friday we're going ad-free for all registered members, and we're asking you to kick in to the DU tip jar to support the site and keep us financially healthy.
As a bonus, making a contribution will allow you to leave kudos for another DU member, and at the end of the week we'll recognize the DUers who you think make this community great.
