Several privately funded companies and small university-based research groups pursuing novel fusion reactor designs have delivered promising results that could shorten the timeline for producing a prototype machine from decades to several years.
but the outlines of such a reactor can now be perceived. Traditional fusion research has centered on large, doughnut-shaped machines called tokamaks,
which exert powerful magnetic fields to compress high-temperature plasmaoiling balls of charged particles that fuse to form helium, releasing large amounts of energy in the process.
the fusion reactors of today, such as the one at the International Thermonuclear Experimental reactor (ITER) project in southern France, use giant coils of electromagnets that consume much more energy than the machine actually produces.
ITER (pronounced ater, which combines scientists and funding from China, the European union, India, Russia, Japan, South korea,
and the United states, is projected to cost dozens of billions of dollars to produce a working reactor sometime in the 2030s.
Two recent developments, offering new and faster pathways to energy-producing fusion reactors, have galvanized the fusion community.
Tri Alpha Energy based in Foothill Ranch, California, said in early August that it has succeeded in keeping a high-energy plasma stable for five millisecondsuch less than the blink of an eye,
but alf an eternityon the scale of fusion reactions, according to chief technology officer Michl Binderbauer. Tri Alpha, says Binderbauer,
such as the Large hadron collider, to bear on the problems of fusion reactors. Specifically, the team has built a device, 23 meters long,
keeping the plasma stable at a high-enough temperature to achieve energy-positive fusion. The recent experiment indicated that the companyhich has attracted millions of dollars in funding from investors including Goldman sachs and Vulcan Inc,
a professor of nuclear science and engineering and the center director, published a conceptual design in July for a machine called the ARC reactor (ffordable, robust, compact.
the ARC reactor can achieve magnetic fields with much higher energyhus enabling a reactor design much smaller than other tokamak-based machines.
and provide an efficient heat-exchange medium to produce electricity. Increasing the amplitude of the surrounding magnetic field raises the amount of fusion power produced in the plasma to the fourth power dramatic increase that could lead to a commercial prototype in a matter of years,
Now the advent of advanced superconductor tapes could enable a compact reactor that produces fusion continuously.
the ARC reactor paper stresses that, for the moment, it a conceptual design only. Whyte is hoping to attract funding to build an experimental machine over the next few years.

Kepler Energy, whose technology is being developed by Oxford university department of engineering science, says the turbines will in time produce electricity more cheaply than offshore wind farms.
It hopes to install its new design in what is called a tidal energy fence, one kilometre long, in the Bristol Channel#an estuary dividing South Wales from the west of England#at a cost of £143m.
The fence is a string of linked turbines each of which will start generating electricity as it is completed,
until the whole array is producing power. The fence total output is 30 megawatts (MW),
And just to visualise that, it like one small nuclear reactor worth of electricity being generated from the tides in the Bristol Channel. he new Transverse Horizontal Axis Water turbine (THAWT)
There is more good news for proponents of renewable energy after the UK government #which is no longer encouraging onshore wind
and solar energy#gave the go-ahead for a large offshore wind farm that could provide power for up to two million homes.
The new wind farm is to be built near the Dogger Bank in the North sea and will have 400 turbines.
with the new development, will form one of the largest offshore wind farms in the world. But the fossil fuel industry is far from abandoning its own interest in British waters as the energy giant BP has announced that it is to invest about £670m to extend the life of its North sea assets.
It said it would be drilling new wells replacing undersea infrastructure, and introducing new technologies to help it to produce as much as possible from the area,

#Safe drinking water Via Solar power Desalination Natasha Wright, an MIT Phd student in mechanical engineering, has designed a solar powered system that makes water safe to drink for rural, off-grid Indian villages.
She designed a village-scale desalination system that runs on solar power. Since her system is powered by the sun,
however, will require extremely low-power sensors that can run for months without battery changes or, even better, that can extract energy from the environment to recharge.
Last week, at the Symposia on VLSI Technology And circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it,

Moreover, the researcherschip achieves those efficiency improvements while assuming additional responsibilities. Where its predecessors could use a solar cell to either charge a battery

#Germany and Canada Are Building Water Splitters to Store Energy Germany which has come to rely heavily on wind
and solar power in recent years is launching more than 20 demonstration projects that involve storing energy by splitting water into hydrogen gas and oxygen.
whether electrolysis as the technology is known could address one of the biggest looming challenges for renewable energy its intermittency.
The electrolyzer projects under construction in Germany typically consist of a few buildings each the size of a shipping container that consume excess renewable energy on sunny and windy days by turning it into an electric current that powers the water-splitting reaction.
and distribution infrastructure already used for natural gas and eventually turned back into electricity via combustion or fuel cells.
Electrolysis has advantages over some other energy storage options. It can be deployed almost anywhere it can store vast amounts of energy
and the hydrogen can be used to replace fossil fuels not only in electricity production but also in industry and transportation
which account for far more carbon emissions. Even so it has long been considered a relatively lousy way to store energy because of its low efficiency about 65 percent of the energy in the original electricity is lost.
But improvements to the technology are reducing costs and the large-scale use of renewable energy is creating new needs for storage making electrolysis a practical option in a growing number of places.
Earlier this year Siemens broke ground in Mainz Germany on what it says will be the world s largest proton exchange membrane (PEM) electrolyzer.
When it opens next year it will have the capacity to produce 650000 kilograms of hydrogen a year the energy equivalent of 650000 gallons of gasoline.
because excess wind and solar power creates a glut of power on the grid. Because power needs to be used as soon as it s generated to keep the grid stable prices are dropped sometimes to zero
Cheap electricity makes electrolysis far more competitive. Electrolysis remains more expensive than producing hydrogen from natural gas at least in the United states where natural gas is cheap.
But it can compete with storage options such as batteries says Kevin Harrison a senior engineer at the National Renewable energy Laboratory in Golden Colorado.
It s also more versatile than the cheapest way to store energy: pumping water up a hill
So an important question is how to minimize the energy it takes to grow these crops.
And of course LEDS use considerably less electricity wasting little as heat. But the most interesting part of Singh and co s analysis is in the potential of LEDS to change the way that vegetables are grown.
and well into the infrared where much energy is lost as heat. By contrast LEDS can be adjusted to emit light in very specific parts of the spectrum.
and that light frequency also influences the biomass of certain plants as well as their nutritional content.

#Dutch Harvest Electricity From Living Plants To Power Streetlights, Wi-fi & Cell Phones Plant-e, a company based out of The netherlands,
has found a way to harness electricity from living plants, using them to power Wi-fi hotspots, cell phone chargers,
which living plants generate electricity. Their technology allows them to produce electricity from practically every site where plants can grow. ia photosynthesis a plant produces organic matter.
Part of this organic matter is used for plant-growth, but a large part can be used by the plant
Around the roots naturally occurring microorganisms break down the organic compounds to gain energy from. In this process, electrons are released as a waste product.
the electrons can be harvested as electricity. Research has shown that plant-growth isn compromised by harvesting electricity,
so plants keep on growing while electricity is produced concurrently. Just imagine, a house with a roof full of plant/tree life powering your home.
On the company website, they feature animated pictures of mini-forests growing on building rooftops supplying power to the entire building.
the main problem is the quantity of energy that can be generated. There is still a long way to go with regards to making enough energy to have a completely reliable commercial product,
but things are looking promising, as the company is already selling products that enable you to harvest energy from plants.
Again, they are also using the technology to power their headquarters For more information on the technology
More and more energy innovations seem to be emerging every single day, like this one. Perhaps this is why the powerful and wealthy Rockefeller family recently sold out of fossil fuels
