Algae is Gooey Power

I’m always impressed by what algae can do. It can be used to generate electricity, make us healthier, it can function as a biofuel, and can be used to clean the air. Algae can almost solve all the worlds problems!

Some enterprising researchers have found out that algae can also be tweaked to create a lot of hydrogen. Hydrogen produced by algae can then be used as a power source elsewhere.

Melis has created mutant algae that make better use of sunlight than their natural cousins do. This could increase the hydrogen that the algae produce by a factor of three. It would also boost the algae’s production of oil for biofuels.

The new finding will be important in maximizing the production of hydrogen in large-scale, commercial bioreactors. In a laboratory, Melis says, “[we make] low-density cultures and have thin bottles so that light penetrates from all sides.” Because of this, the cells use all the light falling on them. But in a commercial bioreactor, where dense algae cultures would be spread out in open ponds under the sun, the top layers of algae absorb all the sunlight but can only use a fraction of it.

Greenbox for Green Driving

Three fishing men from Northern Wales have invented a device that removes upwards of 95% of greenhouse gas emissions from an automobile. It’s called the Greenbox and it replaces the muffler of the car and is designed to be removable so new filters can be swapped in. The reason that the Greenbox needs to be swapped is because the gasses that it traps can be used to encourage algae growth – to make biofuel.

Can this invention get any better?

We’ve managed to develop a way to successfully capture a majority of the emissions from the dirtiest motor we could find,” Palmer, who has consulted for organizations including the World Health Organisation and GlaxoSmithKline, told Reuters

Algae is Good Green Goo

algaeLong time readers of ThingsAreGood may know that we like to talk about algae. Today is no exception, Living on Earth is running an interview with a man who dearly loves algae, particularly burning algae for biofuels.

“Berzin grows algae because they’re super rich in oil. In some species, oil accounts for half the little creature’s body mass. In fact, algae synthesize 30 times more vegetable oil per acre than plants like sunflowers or rapeseed. The algae biodiesel can be used to run engines, or converted into methane or fermented into alcohol. And here’s the best part: algae eat carbon dioxide for breakfast, lunch and dinner. And one thing the global warming world has too much of is CO2 from fossil fuel burning power plants.”

CSIRO Produces DHA

lookingJoanne Bush has written us to let us know about DHA producing plants that can make us healthier.

“I can’t find a date on this page, so I don’t know how new this news is, but CSIRO, our national scientific research organisation here in Australia, has developed plants that produce DHA. Traditionally, this long-chain omega 3 fatty acid was only available from “lower plant forms” like microalgae (and more famously from the fish that feed on them).

The benefits include:
– Yet another reason why vegan doesn’t equal compromised health, &
– Reduced pressure on declining fish resources worldwide.”

I had no idea what DHA is, but wikipedia tells us all about DHA.
