How do you convert your car to run on mushed-up seaweed?

How do you convert your car to run on mushed-up seaweed? It's not something your average man in the street is wondering, but fortunately some intrepid American fuel-pioneers are.
Fed up with the oil industry and pollutant effects of burning petrol, Josh Tickell had been experimenting with biofuels and successfully converted a car to run on waste cooking oil. After concerns that using plant oil created food shortages, they turned their attention to algae. And they reckon that biodiesel created by algae is the answer to the fuel crisis. Well that'd be nice.

Until some of that seaweedy power liquid ends up in your local fill-up station, it's going to be hard to embrace the algae lifestyle, but it's really interesting.

The Algae-Powered car? the people making oil from seaweed



A THIRD OF Japanese cars could run on biofuel made from cultivating seaweed




Japan looking to farm seaweed for biofuel

cultivating seaweed on a number of 10,000 square metre plots of ocean, .
The idea, according to the Tokyo University of Marine Science and Tech, is to grow sargassum fulvellum in the Yamatotai shoal which is 30,000 kilometres wide.
That, reckon the boffins there, is capable of generating 20 kilolitres of bio-ethanol for each 10,000 square metres of cultivated seaweed on nets.

Even if the seaweed idea doesn't work, other boffins reckon they could use high yield rice, unsuitable for human consumption, as a source for bio-fuel.

Toyota Wants to Build Car From Seaweed , an ultralight, superefficient plug-in hybrid with a bioplastic body made of seaweed
that could be in showrooms in 2022.

TOYOTA is looking to a greener future — literally — with dreams of an ultralight, superefficient plug-in hybrid with a bioplastic body made of seaweed that could be in showrooms within 15 years.

The kelp car would build upon the already hypergreen 1/X plug-in hybrid concept, which weighs 926 pounds, by replacing its carbon-fiber body with plastic derived from seaweed. As wild as it might sound, bioplastics are becoming increasingly common and Toyota thinks it's only a matter of time before automakers use them to build cars.

"We used lightweight carbon-fiber reinforced plastic throughout the body and frame for its superior collision safety," project manager Tetsuya Kaida said of the 1/X, which is pronounced "one-xth." "But that material is made from oil. In the future, I'm sure we will have access to new and better materials, such as those made from plants, something natural, maybe something like paper. In fact, I want to create such a vehicle from seaweed because Japan is surrounded by the sea."

A kelp car is not as far-fetched as it might sound. Bioplastics are being used for everything from gift cards to cellphone cases. Demand for the stuff is expected to hit 50 billion pounds annually within five years, a figure that would account for 10 percent of the world market for plastic, according to USA Today. A company called NatureWorks claims the production of its bioplastic Inego produces 60 percent less carbon dioxide than petroleum-based plastic and requires 30 percent less energy. And Oakridge National Laboratory has explored the possibility of producing carbon fiber from wood pulp.

Toyota is laying out its green vision of the future ahead of the Melbourne Motor Show, where it will highlight three sweet hybrids — the next-gen Prius, a cool Camry concept designed in Australia and the 1/X, so named because its carbon footprint is a fraction of that of other cars.

"The 1/X concept is a vehicle that completely redefines what it means to be environmentally considerate," David Buttner, senior executive director of sales and marketing, said in a statement. "The name says it all: a car that weighs a fraction of the others in its class today and uses a fraction of the fuel."

The 1/X has been kicking around the show circuit for more than a year, and the photo is from its North American debut at the 2008 Chicago auto show. It features a tiny 500cc engine and weighs about one-third as much as the Prius while offering about as much interior space. It's got a flex-fuel engine and electric motor powered by lithium-ion batteries.

But don't expect to drive a Toyota Sea-Class anytime soon.

"In reality, the seaweed car is another decade away," Buttner told the Sydney Herald-Sun. "However, it shows where we're going.... Our thinking is that post-2020, cars like the 1/X will be made of plant-based plastic."
