telegraph.co.uk The British designed EM Drive actually works and would dramatically speed up space travel, scientists have confirmedInterplanetary travel could be a step closer after scientists confirmed that an electromagnetic propulsion drive, which is fast enough to get to the Moon in four hours, actually works.The EM Drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically impossible.It produces thrust by using solar power to generate multiple microwaves that move back and forth in an enclosed chamber. This means that until something fails or wears down, theoretically the engine could keep running forever without the need for rocket fuel.The drive, which has been likened to Star Trek’s Impulse Drive, has left scientists scratching their heads because it defies one of the fundamental concepts of physics – the conservation of momentum – which states that if something is propelled forward, something must be pushed in the opposite direction.However in recent years Nasa has confirmed that they believe it works and this week Martin Tajmar, a professor and chair for Space Systems at Dresden University of Technology in Germany also showed that it produces thrust.The drive is capable of producing thrust several thousand times greater than a standard photon rocket and could get to Mars within 70 days or Pluto within 18 months. A trip to Alpha Centauri, which would take tens of thousands of years to reach right now, could be reached in just 100 years."Our test campaign cannot confirm or refute the claims of the EM Drive but intends to independently assess possible side-effects in the measurements methods used so far," said Prof Tajmar in anew"Nevertheless, we do observe thrust close to the actual predictions after eliminating many possible error sources that should warrant further investigation into the phenomena.""Our measurements reveal thrusts as expected from previous claims after carefully studying thermal and electromagnetic interferences.'If true, this could certainly revolutionise space travel.'Shawyer also claims that he is just a few months away from publishing new results confirming that his drive works in a peer reviewed journal.However scientists still have no idea how it actually works. Nasa suggested that it could have something to do with the technology manipulating subatomic particles which constantly pop in and out of existence in empty space.Prof Tajmer presented his findings to the …

popsci.com But don't expect to find them in Costco just yetAlmost all of the electronic devices that we carry around with us all day now rely on one key, but increasingly antiquated, technology: the lithium-ion battery. A mainstay of rechargeable power for the last couple decades, this battery technology has gotten only minor refinements. But a substantial improvement in stored power may be in the offing, thanks to researchers at Stanford University, who have developed a new battery technology based on aluminum.This isn't the first time that aluminum-based batteries have been investigated. The material has a number of advantages over lithium: it's flexible, allowing it to be folded or bent without losing power; can be charged in a minute instead of hours; and is incredibly durable--according to Stanford chemistry professor Hongjie Dai, you can even drill a hole through the battery and it will continue to work. That's good for volatility too: compromise a lithium-ion battery and you'll likely see some sparks or flame, but the materials in this new battery are all non-reactive. And, aluminum is cheaper than lithium, too.All good things, so why haven't we seen more aluminum batteries? The catch to date has been finding another material to work with aluminum in creating energy. The Stanford team ended up using our old friend graphene to play the cathode to aluminum's anode. But though that's helped unlock better performance, including more charge cycles--7,500 versus the 1,000 you'd likely get out of a Li-ion battery--aluminum-ion's woes aren't all behind it. The voltage provided by an aluminum-ion battery is only about half of that what you'd get from a lithium-ion cell. And, as Ars Technica points out, the overall power density--the amount of juice you can store in a battery vis-a-vis its size--more closely resembles the large lead-acid battery you'd find in your car.So aluminum-ion batteries still aren't quite ready for primetime, but you can bet that electronics manufacturers, makers of electric cars, and power companies all have their eyes on the development of this technology.Meanwhile, researchers are working to enhance the performance of lithium-ion batteries using materials like carbon nanotubes, but the returns are diminishing. And other new technologies, like sulfur-based and metal-air batteries have their own downsides as well. Should scientists be able to increase the power and energy density of aluminum-ion batteries, its speed of charging, lack of …

Way to go Ghana!
theguardian.com The largest solar power plant in Africa will be built in Ghana, the British company behind the plan said on Tuesday.Source of much of the world's cocoa and an increasingly significant oil producer, Ghana's new drive to exploit the sun's energy is predicted to create hundreds of jobs and increase the country's electricity capacity by 6%, as well as cutting emissions.Blue Energy, the renewable energy developer behind the $400m project, which has built a solar farm 31 times smaller outside Swindon, said the 155MW solar photovoltaic (PV) plant will be fully operational by October 2015. Construction on the Nzema project is due to begin near the village of Aiwiaso in western Ghana by the end of 2013, with the installation of some 630,000 PV modules.The power plant, which at the time of planning would be the fourth biggest of its kind in the world, will be the first major scheme to claim payments from Ghana's feed-in tariff incentive scheme, created by the government in 2011. Ghana has a target of increasing renewable energy capacity from its current 1% of the country's energy mix to 10% by 2020.Chris Dean, chief executive of Blue Energy, said: "Ghana's forward-thinking strategy puts it in a strong position to lead the renewable energy revolution in sub-Saharan Africa. Nzema is a case study in how governments can unlock the huge potential for solar energy in Africa. We are delighted that it will make a strong contribution to the national economy, provide much needed generating capacity and help develop the skills of the future."Douglas Coleman, the project's director at Blue Energy, told the Guardian that the company was using solar PV instead of the distinctive 'troughs' used in concentrated solar power technology seen in north Africa and the Middle East in part because PV only requires light, not direct sunlight. The choice of PV means the farm will still generate electricity during the more than 100 cloudy days Ghana experiences each year, he said.The company said it expects to create 200 permanent jobs and 500 during the construction phase, which already has the go-ahead from planning authorities.The plan for the Ghanian plant follows recent denials of a crisis at the separate Desertec initiative – which envisions solar plants in north Africa providing green energy for Europe – following the withdrawal of Siemens and Bosch from the initiative.Ghana recorded the fastest growth in Sub-Saharan Africa last year, with GDP growing at 14.3%, driven by oil …
techcrunch.com Google today announced that it is investing $12 million in a 96 megawatt solar photovoltaic plant in South Africa. This marks Google’s first renewable energy investment in Africa and its 12th overall renewable energy investment. Once it’s completed, Google says, the Jasper Power Project, which is situated in the Northern Cape province of South Africa, will generate enough power for 30,000 South African homes. In total, Google has now committed more than $1 billion to green energy projects.In South Africa, Google is joining SolarReserve, Intikon Energy and the Kensani Group as the main funders for this project, which is also backed by Rand Merchant Bank, the Public Investment Corporation, Development Bank of South Africa and the PEACE Humansrus Trust. The project will be one of the largest in South Africa and cover about 450 acres with more than 325,000 solar modules.In today’s announcement, Google’s director for energy and sustainability, Rick Needham, also lays out some of the criteria the company uses to make these kinds of investments. He notes, for example, that Google will “only pursue investments that we believe make financial sense.” Because South Africa has policies that support these kind of projects, Google believes it is an attractive place for it to invest in this technology. The company, however, is also looking for “projects that have transformative potential – that is, projects that will bolster the growth of the renewable energy industry and move the world closer to a clean energy future.”

PEAK OIL IS HORSE MANURE
The stone age didn't end because we ran out of stones
Dateline: 20 January 2021
Back in the day, when horse drawn carriages and buggies were the preferred mode of transport for anyone, there was a big fear in Paris, London and New York that there wouldn't be enough stabling for all the horses required in the future, to say nothing of all the manure that was piling up in the streets. Then we invented motor cars, and the problem of peak horse manure disappeared.
That's a salutary tale to bear in mind when we talk of peak oil. There will be a time when our consumption of oil peaks, plateaus and then starts to decline. And it won't be because we ran out of stones, I mean oil, but because there are better, cleaner, more sustainable, and ultimately cheaper ways to serve our ever increasing energy needs.
And we will need more energy, even more than we consume today, which is more than ever before. Even though it's slowing, the world's population is growing; not only in numbers, but also in sophistication, affluence, modernity, mobility and increasingly digital lifestyles. Many countries have free broadband, and in some, access to electricity is considered a basic human right.
Let's not be fooled by efficiency. It's an inconvenient paradox that, the more efficient our cars, planes, homes and gadgets get, the more energy we consume as a whole, as more people enjoy the benefits more often. But we're also becoming more efficient at producing power.
Forget about wind turbines and wave generators. What's really reducing our need for oil is solar power. We've known for decades that the sun produces more direct energy than we can possibly use. It was just the ability to capture, transform and distribute that energy efficiently that needed some work. Now it's happening in a big way, and soon the grid will be 80% powered by solar technologies - and most of that comes from you and me, ordinary households connected on the energy internet.
So I'm looking forward to peak oil. It will mean we've fully reconfigured our power paradigm and installed the killer app. It won't make the sheiks and oligarchs happy, but the greens will rejoice. Bring it on!
