Thrown-together Algae Photobioreactor Well i was curious, so why not? bucket & rain water. got the fishtank airpump, hoses & bubblers from a pet store for under $40 you can use tapwater too, it'll take a day or so in the sun for the chlorine to disappear. I didn't have any algae to start off with, this stuff just grew in there on it's own. In a few months this is what my new pet looks like. No fertiliser (cept the bees that drown themselves). I'm considering peeing into it. no CO2. just air bubbling through and direct sunlight. couldn't be cheaper. If you're wondering what the other thing is becide the white bucket, it's another bucket i've lined with cheap reflective Mylar (ie: an emergency blanket). The shiny aluminium layer is eroding off in the water though - should have faced it backwards. -------- I'm planning on grabbing some clear "polytube" packaging plastic and using that instead of the bucket. Like these guys: http://tribes.tribe.net/chlorophyllcollective/photos Also i'll add a bit of pee into it, nitrates! Should make it go mental. I wonder if algae could be used instead of tree plantations - for CO2 offsets. Afterall algae is the fastest growing (and fastest CO2 absorbing) plant, why bother planting trees? It grows at an insane speed if you directly feed it CO2 emissions (and some are doing this, see my other videos), but even if you just feed it normal air it grows way faster than trees.

Algae Photobioreactor at Hazelwood coal powerplant i just managed to catch the end of this segment on Lateline Business. Preceeding this footage was a guy from Alternative Technology Association saying he was "happy with the use of biofuels, as long as the emissions from producing those fuels are less than the emissions from their use". Sage advice. Algae oil or Algae biodiesel is such a fuel. This is footage of an Energetix trial algae plant in Victoria Australia, being fed some of the emissions from Hazelwood coal power plant. Hazelwood is currently Australia's worst polluting power plant - but that might soon change. Energetixs (a biodiesel company owned by the Victor Smorgon Group) now has the exclusive Australian license to the algae growing process owned by Greenfuels(tm). Full Transcript of segment here http://www.abc.net.au/lateline/business/items/200706/s1962973.htm where you'll also find a vodcast of the whole segment on the right.

LightCraft Launch Oct 2000 - laserbeam powered propulsion Prior to liftoff, a jet of compressed air is used to spin the lightcraft to about 10,000 revolutions per minute (RPMs). The spin is needed to stabilize the craft gyroscopically. Once the lightcraft is spinning at an optimal speed, the laser is turned on, blasting the lightcraft into the air. The 10-kilowatt laser pulses at a rate of 25-28 times per second. By pulsing, the laser continues to push the craft upward. The light beam is focused by the parabolic mirror on the bottom of the lightcraft, which heats the air to between 18,000 and 54,000 degrees Fahrenheit (9,982 and 29,982 degrees Celsius) -- that's several times hotter than the surface of the sun. When you heat air to these high temperatures, it is converted to a plasma state -- this plasma then explodes to propel the craft upward. (note: the Lightcraft here actually employed a plastic ablative propellant. So the "it burns air" statement is not entirely correct - the laser is igniting air AND PROPELLANT) Lightcraft Technologies uses a Pulsed Laser Vulnerability Test System (PLVTS), an offspring of the Star Wars defense program. The 10 kw Carbon-dioxide pulsed laser being used for the experimental lightcraft is among the most powerful in the world. more info: http://science.howstuffworks.com/light-propulsion.htm http://www.lightcrafttechnologies.com Tags: Beamed Energy Propulsion Light Microsatellite laser launch space lightcraft satellite test Carbon-dioxide CO2 PLVTS

Lander Level 1 - get everything Havn't played the game in a while, i initially can't remember what key SHOOTS. This is how you do the first level and get all the cash. If you don't take out those radars first there isn't as much cash to grab, so take em out! zoomzoom i love lander Tags: psygnosis lander

MIT Algae Photobioreactor An algae photobioreactor on the roof of MIT university. The clear polycarbonate tubes are approx 3 meters high, and 10-20 centimeters in diameter. It removes upto 86% of the NOx and 40% of the CO2 of the smokestack emissions that are bubbled through it. The algae are feeding on exhaust with 13% CO2 content. This size algae photobioreactor can't handle the entire exhaust emissions, it would need to be much larger for that. This photobioreactor you see here on the roof of MIT, has since been dismantled and reassembled in Naboomspruit (now called Mookgopong) South Africa at a biodiesel plant. http://www.infinitibiodiesel.com/ read more: http://images.google.com.au/images?q=Greenfuel Tags: hydrogen algae photobioreactor bioreactor CO2 carbon energy biodiesel ethanol biomass

Operation Condor - Zorb ball scene Jackie Chan bounces down a cliff in a Zorb* Ball. From the introduction to Armour of God II: Operation Condor. *well not a Zorb(tm), but same thing. i dunno if it's real of not, but i recon you could probably do it somehow. Send your ideas. I wanna roll one of these off a plane! Tags: human hamster ball zorb jackie chan operation condor armor armour of god II beachball Fei ying gai wak sphereing sphere

"Hot Rod" - Orion spacecraft prototype In 1959 this mock-up version of the Orion was launched helping prove the validity of the design. 1 Meter in diameter, weighing 105kg, it was not powered by nuclear blasts but by 1 kilogram balls of C4 explosive. Watch closely and you can see them come out the back. It reached a height of 105meters.
