They have spent over 2 years planning and building an algae farm around here and it still isn’t finished. The technology isn’t all that good and I havn’t seen anything about cost effectiveness.
Honestly, I don't know all that much about it. Made sense to me to give it a try.
In a rational world, you and I would say "Hmmmmm, this might fly. Let's try it." and if it doesn't produce energy at a better-than-breakeven cost, we'd scrap the idea and move to the next thing.
Unfortunately, we're talking about government. So Common Sense will go out the window.
Heck, they're still throwing money by the snowshovel-full at Solar and Wind power, which are two technologies that anyone with an Engineering Degree (or just a FReeper with a decent amount of sense) can tell you won't ever scale up.
