Mission to reveal ‘Truths’ about climate change

‘Truths’ is an acronym* but it helps with the publicity. The satellite ‘will be sensitive to light in the visible and near-infrared part of the electromagnetic spectrum’.

The UK is going to lead a space mission to get an absolute measurement of the light reflected off Earth’s surface, reports BBC Science.

The information will be used to calibrate the observations of other satellites, allowing their data to be compared more easily.

Called Truths, the new spacecraft was approved for development by European Space Agency member states in November.

Proponents of the mission expect its data to help reduce the uncertainty in projections of future climate change.

Engineer converts Tesla’s Model 3 into cheaper hybrid

Of course he could have removed the heavy battery pack altogether and replaced it with an equivalent car engine, in theory at least. But he didn’t, so on with the report…

An engineer from Austria has recreated an even cheaper Model 3 by converting Tesla’s flagship electric vehicle into a hybrid by adding a two-cylinder gasoline engine and “downgrading” the battery pack, reports OilPrice.com.

Frank Obrist from Lustenau, Austria, founder of engineering company OBRIST Powertrain, wants to make EVs more affordable.

OBRIST Powertrain claims that the hybrid Tesla would have twice the range compared to the fully electric vehicle as designed and manufactured by Tesla.

California dreaming of an energy storage miracle

This public statement looks long on ambition but short on realistic and/or affordable possibilities. They openly admit that existing ‘green’ tech won’t cut the mustard on its own, as everyone knew – or should have known – all along. In other words their legislated targets can’t be met, as things stand. The same problems will exist everywhere else that tries to enforce similar energy policies in pursuit of a ‘carbon-free’ mirage.

The California Energy Commission (CEC) has released a solicitation (GFO-19-305) to fund innovative, non-Li-ion energy storage research projects, including green electrolytic hydrogen systems, reports Green Car Congress.

The Commission notes that the state’s statutory requirements (SB-350, SB-100) for low-GHG electricity cannot be met with currently fielded technologies alone, because those technologies do not have the energy density, daily cycle capability, longevity, safety, and price to be viable for the diverse set of applications that will be needed in the State.

Small nuclear reactor proposal passes latest hurdle

The battle to make nuclear power more practical and affordable steps up a gear.

NuScale Power’s small modular reactor (SMR) design has cleared the latest stage of the U.S. Nuclear Regulatory Commission (NRC)’s review process, reports New Civil Engineer.

The reactor is the world’s first SMR to undergo design certification review by the NRC, after passing phase 4 of the review process. It is on track for approval by September 2020.

SMR supporters see the reactors as a safer, more affordable nuclear power option.

Solar train – OK for millionaires?

A bit of fun for tourists, but an electric bus would have been a lot cheaper.

Well, 10% solar-powered – that’s the target. Of course solar has its variables, mainly weather conditions and hours of daylight. So is this ‘solution’ worth the bother and cost, or not? The era of batteries on train locomotives has also arrived – see ‘Adding a third dimension – battery power’ here.

How many times have we looked at clever innovation and wondered why on earth no one thought of doing it before?

Often the simplest of ideas seem to lead to the most elegant of engineering solutions, says RailEngineer.

The truth is, of course, that invention is only half of the story. Sometimes the right meeting of minds must happen before a bright idea can become a reality.

To the best of our knowledge, the direct supply of solar power to rail traction systems has never been done, anywhere in the world.

System provides cooling with no electricity

Credit: scienceblog.com

It’s claimed this invention could be used to improve any type of cooling system.

Imagine a device that can sit outside under blazing sunlight on a clear day, and without using any power cool things down by more than 23 degrees Fahrenheit (13 degrees Celsius).

It almost sounds like magic, but a new system designed by researchers at MIT and in Chile can do exactly that says TechXplore.

The device, which has no moving parts, works by a process called radiative cooling.

It blocks incoming sunlight to keep from heating it up, and at the same time efficiently radiates infrared light—which is essentially heat—that passes straight out into the sky and into space, cooling the device significantly below the ambient air temperature.

Aluminium-Air power cell tech set to make a comeback

Experimental Aluminium-Air power cell

The military developed and used ALuminium-Air power cell tech decades ago. New discoveries and advances in electrolyte mean it might become viable for commercial and domestic use. The Daily Mail has this:

Two years ago, Jackson claims, motor manufacturers lobbied the Foreign Office to bar him from a prestigious conference for European businesses and governments at the British embassy in Paris, which was supposed to agree a blueprint for ensuring all new cars are electric by 2040. The bid to exclude him failed. Now, with the signing of the Austin deal, it seems he is finally on the road to success.

He has also secured a £108,000 grant for further research from the Advanced Propulsion Centre, a partner of the Department for Business, Innovation and Skills. His technology has been validated by two French universities.

He says: ‘It has been a tough battle but I’m finally making progress. From every logical standpoint, this is the way to go.’

Latest ‘green tech’ scheme: How liquid air could help keep the lights on

The fact that this kind of thing gets touted at all says a lot about the state of electricity generation in today’s trace-gas-fearing climate obsessed world. They talk of a ‘carbon free future’, but ignore the reality that world demand for oil, coal and gas is rising year on year as prosperity spreads around the globe and populations continue to increase.

It sounds like magic but it is real – a plan to store cheap night-time wind energy in the form of liquid air, reports BBC News.

Here is how: you use the off-peak electricity to compress and cool air in a tank, so it becomes a freezing liquid.

When demand peaks, you warm the liquid back into a gas, and as that expands it drives a turbine to create more electricity.

The technology, created by a backyard inventor, is about to hit the big time.

Water harvester makes it easy to quench your thirst in the desert

The report says the productivity of the new water harvester is ’10 times that of the previous device and 100 times higher than the early proof-of-concept device’, and that ‘no traces of metal or organics have been found in the water’.

In 2017, UC Berkeley chemists demonstrated that a new MOF design could rapidly adsorb water from even dry air, allowing it to be condensed and collected for drinking, reports TechXplore

A second-generation MOF can now cycle through adsorption and desorption in 20 minutes, allowing continous collection of more than a liter per day per kilogram of MOF using solar power.

The new MOF is the basis of a planned microwave-sized device that delivers 7-10 liters per day.

With water scarcity a growing problem worldwide, University of California, Berkeley, researchers are close to producing a microwave-sized water harvester that will allow you to pull all the water you need directly from the air—even in the hot, dry desert.

UK Government announces £300m to accelerate greener travel – they hope

Ex-drone, somewhere in Siberia

Incontinent pigeons could be the least of pedestrians’ worries if any of these headline-seeking flights of fancy come to fruition. Election soon?

Funding will support new technologies including electric passenger planes, flying urban taxis and freight-carrying drones, says Energy Live News.

Up to £300 million of investment has been announced for the development of cleaner and greener forms of transport in Britain.

The government will provide £125 million of funding, which will be supported by industry co-investment of up to £175 million for new technologies including electric passenger planes, flying urban taxis and freight-carrying drones.

It is part of a new Future of Flight Challenge announced by Prime Minister Boris Johnson, which will be delivered by UK Research and Innovation.

The world’s first solar road has officially crumbled into a total failure

Solar panel road [image credit: Wattway]

The rotting leaves didn’t help, says ScienceAlert. Neither did the local tractors. Solar panels should be angled towards the Sun anyway, but that kills the whole road idea.

In July, the French daily newspaper Le Monde reported that the 0.6-mile (1 kilometre) solar road was a fiasco.

In December 2016, when the trial road was unveiled, the French Ministry of the Environment called it “unprecedented”. French officials said the road, made of photovoltaic panels, would generate electricity to power streetlights in Tourouvre, a local town.

But less than three years later, a report published by Global Construction Review says France’s road dream may be over.

Saudi Arabia’s plan for a $500 billion city is as bizarre as you’d expect

They call it ‘the world’s most ambitious project‘. Mind-boggling expenditure if it ever gets built. The solar city aspect of the plan gets panned here.

The riches of Silicon Valley have enabled some extravagant and quixotic projects, but they’ve got nothing on what oil money can do, says MNNOFA News.

A new report from The Wall Street Journal shares some of the proposals for Saudi Arabia’s biggest megaproject yet: a city built in the desert named Neom, where robots will outnumber humans and hologram teachers will educate genetically-enhanced students.

The details are stunning. It’s a mixture of dystopian fiction (AI surveillance cameras everywhere!) and childish imaginings (let’s build a robot dinosaur park!). Taken together, the plans remind of you what a dedicated nine-year-old can achieve in Minecraft. Yes, the scale and ambition are impressive, but it’s not like you could do this in real life, right?

Cloud seeding? Robot servants? A fake moon!? Sure, why not.

The new gas revolution that could make renewable energy obsolete

H/T The Global Warming Policy Forum (GWPF)

Well, possibly but it involves carbon capture. The costs and practicality have to be demonstrated first, and that tends to undermine most of such claims. Worth a try though.

If the Net Zero power plant performs as expected this is a real game changer for natural gas, says Forbes.

Since the United States is sitting on more natural gas than any country in the world, and it’s getting cheaper to get it out of the ground, this is no small game to change.

An actual game changing technology is being demonstrated as we sit in our air-conditioned abodes reading this. And it is being demonstrated by North Carolina–based Net Power at a new plant in La Porte, Texas.

The process involves burning fossil fuel with oxygen instead of air to generate electricity without emitting any carbon dioxide (CO2). Not using air also avoids generating NOx, the main atmospheric and health contaminant emitted from gas plants.

Germany opens first overhead electricity test track for trucks on autobahn

E-truck test route [image credit: transport-online.de]

Back to the future? This is the truck equivalent of the trolleybuses that operated in some UK cities until the 1960s, and are still in use in a few other countries – except that these trucks do still have engines. Another expensive and over-engineered attempt to make a tiny reduction in trace gases in the atmosphere, in pursuit of futile ‘climate targets’ and to fool the public that such things matter.

Germany has opened its first autobahn test track for overhead power line (catenary) e-trucks, the environment ministry (BMU) announced in a press release [which says: ‘The Federal Environment Ministry has funded the construction of the plant with 14.6 million euros. For the field trial in Hesse, which runs until the end of 2022, a further 15.3 million is available’].

After years on a non-public testing ground, five hybrid test trucks will use the five kilometre long autobahn section between Frankfurt and Darmstadt in the state of Hesse until 2022, reports Clean Energy Wire.

The trucks are equipped with electric and diesel engines as well as batteries that can be quickly recharged via the overhead lines.

Air-Breathing Rocket Engine Gets Green Light for Major Tests

The makers claim that ‘global and orbital travel will never be the same’.

A new air-breathing rocket engine is ready for a major round of testing in the next 18 months after having passed a preliminary design review by the European Space Agency (ESA), reports Space.com.

The Synergetic Air-Breathing Rocket Engine (SABRE), which is being developed by the U.K. company Reaction Engines, can switch between two modes.

In aircraft-engine mode, it uses oxygen from the atmosphere, and in rocket-engine mode, it burns an oxidizer carried onboard together with the fuel liquid hydrogen.

The technology, deemed particularly promising for suborbital spaceflight and supersonic intercontinental travel, could one day revolutionize space transportation, advocates say.

Tree-planting drones could help restore world’s forests

Image credit: Biocarbon Engineering

This report is talking about coastal mangrove forests in particular. The target is over a billion new trees, but it’s claimed two operators with ten drones could plant 400,000 trees a day.

British engineers have created a seed-planting drone which could help restore the world’s forests, reports the London Evening Standard.

Biocarbon Engineering, a start-up based in Oxford, designed the drones to fire seed missiles across fields, planting hundreds of potential trees in a matter of minutes.

In September 2018, the drones were deployed in a field just south of Yangon, Myanmar.

The seeds they sowed have since grown into tiny mangrove saplings, about 20-inches tall.

“World’s first working thermal battery” promises cheap(er) energy storage

Thermal battery

Various battery proposals sound promising, but few seem to survive the development stage and make it commercially. This outfit says it already has some sales, and plans to ‘build 100-megawatt-plus installations within a couple of years.’ Will it work out that way?

A South Australia-based startup says it’s built a thermal energy storage device with a lifetime of at least 20 years​ that can store six times more energy than lithium-ion batteries per volume, for 60-80 percent of the price, reports New Atlas.

South Australia has recently put the world’s biggest lithium battery into operation – but perhaps it should’ve waited.

Climate Change Technologies, also known as CCT Energy Storage, has launched its TED (Thermal Energy Device) with a set of remarkable claims.

Researchers create hydrogen fuel from seawater

Desalination in California

As usual with these types of experiment, nothing can be assumed unless or until the tests of economic and industrial viability have been passed. They say the electrode ‘is able to go more than a thousand hours’ but that’s still only a few weeks. Storage and management of hydrogen is known to be tricky and expensive compared to most other fuels.

Stanford researchers have devised a way to generate hydrogen fuel using solar power, electrodes and saltwater from San Francisco Bay, reports Phys.org.

The findings, published March 18 in Proceedings of the National Academy of Sciences, demonstrate a new way of separating hydrogen and oxygen gas from seawater via electricity.

Existing water-splitting methods rely on highly purified water, which is a precious resource and costly to produce.

Solar farms in space could be renewable energy’s next frontier

Maybe there’s some military angle to this. As the report says, it ‘will be difficult and costly’. Capturing the sun’s power will be cloud-free, but when transmitting to the ground the clouds are still there.

China wants to put a solar power station in orbit by 2050 and is building a test facility to find the best way to send power to the ground, reports MACH (NBC News).

As the green energy revolution accelerates, solar farms have become a familiar sight across the nation and around the world.

But China is taking solar power to a whole new level. The nation has announced plans to put a solar power station in orbit by 2050, a feat that would make it the first nation to harness the sun’s energy in space and beam it to Earth.
