As you read this, a team of adventurers is cross-country skiing their way to the bottom of the world. But this is no ordinary Antarctic expedition – this is the first attempt made by an adaptive athlete to reach the South Pole on a sit ski. Marking the 100-year anniversary when Captain Robert Falcon Scott’s Terra Nova expedition reached the earth’s most remote spot, The Push: South Pole Adventure team is making history. The team is led by Grant Korgan, who injured his spinal cord, has no control of his legs from the knees down and has poor circulation in his feet. To keep his feet warm in the sub-zero temperatures, he’s relying on a Goal Zero portable solar photovoltaic system and some Therm-ic high-tech heated socks, without which he would never be able to reach his goal.
Swiss and German private equity funds Terra Nex and Middle East Best Select announced plans to build 400 megawatts (MW) of solar power generating capacity in the southeastern Arabian peninsula country of Oman, according to recent news announcements. The $2-billion project calls for construction of solar power installations, as well as facilities to manufacture solar photovoltaic (PV) panels for use in Oman and for export.
Scientists at MIT and RWTH Aachen University may have revolutionized the effectiveness of concentrated solar plants – by emulating the pattern found on a sunflower, otherwise known in science as Fermat’s spiral. By rearranging the CSP’s massive heliostats, or mirrors, to resemble the yellow flower’s petals, the solar power harvester can take up 20% less space. Making the system more compact increases the CSP’s efficacy, giving it a higher potential for energy generation.
As we move towards a time of increasingly depleted energy resources, we find ourselves faced with the question of how to sustain ourselves and the planet. As it is not feasible to continue using conventional sources like coal and natural gas, we’re leaning more towards renewable sources like solar, tidal, and wind energy. They can produce as much, if not more, power than conventional sources, provided they are harnessed properly using the right technology.
Probably the most efficient way of harnessing solar power is by using Concentrated Solar Power plants, or CSPs. Their design, however, is based on large mirrors (heliostats) placed in rows around a central tower, onto which they reflect the sun’s energy.
Some more astonishing stats on the progress Germany is making on solar power thanks to good, steady and predictable renewable energy policy: Greentech Media shares the astonishing fact that in the month of December alone Germany installed 2 GW of solar PV. For the whole of 2011, Germany installed 7 GW.
The US managed to install 1.7 GW in the same time period—which isn’t to knock US installation rates so much as to further highlight the massive Germany push to install more PV before the feed-in tariff for it drop as planned.
The Maker Faire is a place where weird and wacky inventions are welcomed and championed, which is surely why Bob Schneeveis and Grant Grundler decided to debut their crazy solar powered electric chariot there. The chariot is a modern-day renewably powered take on the ancient Roman cart which is pulled around by a roller blading robot who glides with the greatest of ease. Video of the chariot in action after the jump.
Renewable resources and non renewable resources are at two ends of a tug-of-war battle. While the latter is presently being used to an exhaustive extent, the former is still trying to find a prominent place in the list of energy sources. Conventional sources like coal have been used for a number of decades to power industries and homes. Its abundance and cheap cost is what propelled many to turn to it in the first place. The Industrial Revolution of the 18th and 19th centuries saw huge amounts of coal being used to drive countries like Britain to the forefront of progress. Earlier, this natural resource was used in small quantities and coal could be mined from close to the surface of the earth. However, as demands increased, there was a need to drill ever deeper.
