Organic seaweed farm could power bio-hydrogen airship by 2030? May 24, 2010
Here is a story about a futuristic airship that could be powered by organic seaweed farms. This airship known as a Hydrogenase has total sci-fi feel but apparently could be a reality by as early as 2030. Would you be willing to take a flight or live in one? Here are the full details from our friends at Treehugger and you can see come more cool concept images below.
New way to harvest electricity
Didn’t think this would ever be possible, but it seems fairly simple. I don’t know how much electricity could actually be harvested though..

“Rabbits produce manure that is arguably the BEST for the gardeners’ purposes. It is ready for use with absolutely no composting: no building bins, no heavy work turning the piles, no trucking in loads of manure from animals who may be heavily medicated. Just park an old wheelbarrow under the cage if you like, wheel to the garden, and dump. If you want to water houseplants or tender seedlings, make a manure tea using a quart or more of rabbit droppings soaked in five gallons of water. Let it sit for a day or two, stir a few times, then strain the tea into your watering can to avoid clogging with the fine fibers. You can dump the fibrous remainder around your berry bushes or other shrubs as mulch.”
