Green Technology and Environment

This is a blog of my green tech & environmnet news articles that I find interesting and I curate them to stay on topic with about 1 to 3 posts per day. Anyone is free to commentand discuss the posts as long as it stays on the topic of the post.
 
It is being run as a Collection which means only I am posting but anyone is free to comment and discuss the posts as long as it stays on the topic of the post.
 
Out of long experience this has shown me to be the most focussed way of obtaining relevant interesting news without lots of spam and off topic chatter. I have no intention of spending time moderating a social Community. I've previously had over 500,000 followers on G+ and they followed because posts stayed strictly on topic. I hope people will appreciate that here and if you'd rather do social chat there will be other Groups for that. I honestly can't find time to do news as well as moderate lots of other posts that I have not researched myself.

    PanGoPod: an eco-friendly South African off-grid tiny home

    PanGoPods are off-grid eco-friendly mobile homes. They are bigger than a caravan but smaller than a Park Home. This sort of housing is common in the USA, Canada, Australia, and New Zealand, where they are called Tiny Homes.

    The PanGoPods detach from their trailers: they can be kept on the trailer or ‘planted’ on site and removed again. A PanGoPod plus trailer weighs 3500 kg and can be towed by a large 4×4. PanGoPods run off of solar po...  more

    SUVs are way worse for the planet than anyone previously thought - the average petrol SUV emits over ten per cent more CO2 per km than the average petrol car

    While overall emissions from passenger cars fell by 75 metric tonnes of carbon dioxide (MtCO2) between 2010 and 2018, emissions from SUVs grew by 544 metric tonnes – more than the increase from heavy industry, aviation, trucks or shipping.

    Part of the problem, says Aronczyk, is that once supersized cars start to take off in a country, con...  more

    World’s Second-Largest Ferry Operator Switching From Diesel to Batteries

    Washington State Ferries had looked at using hybrid or liquid natural-gas-powered vessels as far back as around 2012, said Sterling, but found the technology wasn’t mature enough. Now, improvements in battery technology coming out of the automotive sector are prompting a second look.

    The ferry operator’s electrification program will start with the most polluting vessels, three Jumbo Mark II ferries, which consume 5 millio...  more

    Lime Electric scooter service to launch in Cape Town CBD

    Electric scooter and bike rental company Lime is launching a fleet of scooters throughout the Mother City. The fleet of scooters will be available for rental at privately-owned locations across the city, and there is also an app available to use. The app works similarly to the Uber app, and will allow users to hire dock-free rental bikes, e-assist bikes and electric scooters.

    Watch this electric motorcycle ride completely submerged in water (seriously) - electric motors have no air intake and are generally sealed

    You’d be forgiven for mistaking this electric motorcycle for a submarine, considering they both seem to operate just fine underwater.

    The bike is a Milandr SM-250, an electric dirt bike from a Moscow-based EV company. It features a top speed of 120 km/h (75 mph), a 0-100 km/h (0-62 mph) time of 4 seconds, and a hefty battery pack measuring 6.6 kWh.

    But mo...  more

    Arcimoto’s electric three-wheeler test driven through New York City traffic - $19,900 gets you 100 miles (160 km) range at up to 75 mph (120 km/h)

    It may look a little bizarre but it is very practical for inner city driving and parking. It's running costs will also be pretty cheap. After introducing the first prototype three years back, the vehicles are starting to be delivered to customers. It comes with creature comforts like heated seats, heated grips, a phone mount, the ability to pair your...  more

    Planes Are Ruining the Planet - New, Mighty Airships Won’t - Some scientists are serious about resurrecting Zeppelins for Low-Carbon Travel

    Interesting idea as we know so much more today versus when the first airships were used. They may be constrained by lifting weight but larger dimension freight is possible and these airships are not as constrained as ships and planes in terms of routes and ports for landing. The speed is a lot slower than planes but can be a lot faster than ships.

    Will Your EV Keep the Lights On When the Grid Goes Down? Yes, a Leaf can power an average home in Japan for two to four days!

    For much of any given day, EVs are parked in garages or at offices. When paired with a power control system, the battery packs in those EVs are functionally little different than a stationary battery system.

    One big difference: EV battery packs are much larger. Many EVs on the market today are outfitted with battery packs with capacities ranging from 40 to 65 kilowatt-h...  more

    Coolest Gadgets' Best Indoor Air Quality Monitors for 2019

    Air quality is essential for everyone, but it is especially crucial for those who have problems with their breathing. Allergies, asthma, COPD, emphysema, and other upper respiratory conditions can make you sensitive to environmental changes as well as pollution and particulates in the air. Keeping tabs on what is happening to the air inside your home is one way you can stay healthy and protect your delicate airways.

    House plants have little effect on indoor air quality, study concludes - Many 'sensible' sounding ideas from the past prove not to be so

    New research from a duo of environmental engineers at Drexel University is suggesting the decades-old claim that house plants improve indoor air quality is entirely wrong. Evaluating 30 years of studies, the research concludes it would take hundreds of plants in a small space to even come close to the air purifying effects of simply opening a couple of windows...  more

    Battery Supply Constraints On The World Market & Electricity Blackouts Spur South African Battery Assembly

    With a huge world market to address, a limited quantity of the batteries from these global brands get to reach Africa. Most of these OEMs do not have local offices in Africa, resulting in long delivery lead times, absence of local back-up and service support, and to some extent warranty issues as some products come on the market as grey imports from third parties. This has created the perf...  more

    Over 11,000 scientists from 153 countries around the world declare a 'climate emergency'

    A new study signed by more than 11,000 scientists in 153 countries supports the use of the term "climate emergency," a phrase more commonly heard in the calls of climate activists, according to the Washington Post. This is the first time that a group of scientists this large has formally backed addressing climate change as an "emergency." The term's embrace from the global scientific community points to a g...  more
