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.

    Three scenarios for EV uptake in SA: Keep Up, Flood, or Own Bubble - Keep Up is Best but no Rollout or Spark Yet

    With the gradual demise internationally of the diesel engine – as diesel cars are facing a potential ban in a number of countries, especially in Europe – all the engine derivatives within a model range may soon not be available for import into South Africa, as diesel derivatives are likely to be replaced with EVs. But we have no decent EV infrastructure yet.

    LEVC Says Electric Taxis Have Saved £3.5 Million In Fuel Costs and about 850,000 litres of diesel fuel For London Cabbies

    The electrified taxis drastically reduce NOx pollution — down 99.5% compared to typical diesel-powered black cabs. Collectively, they have given rides to 13 million passengers and accumulated more than 21 million passenger miles — enough to travel to the moon and back 45 times. The company says its vehicles save each individual cab driver about £100 each week on fuel costs.

    Thalia Electric Car, Designed & Built In Mexico, Nears Production for $18,000 - No electric car in production in South Africa yet

    Yes, South Africa manufactures combustion engine cars for the local as well as the export market but everything continues oblivious the changes already happening in the market. It's good to see Mexico is already making some bold moves to produce their own electric vehicles and sourcing their parts directly from China.

    Prepaid solar electricity coming to your homes in South Africa and Nigeria for around ZAR 0.82 cents per KWh

    WiSolar announced the soon to be launched solar-as-a-service product in Nigeria and South Africa last week, saying it plans to use its existing capabilities and channel partners to scale and increase coverage. A company spokesperson says: “We have again reiterated the goal of working to protect the environment and strengthen country communities through solar energy projects with the rece...  more

    The Zero FXS electric motorcycle could be the ultimate commuter motorcycle starting at $8,495

    The 2019 Zero FXS starts at just $8,495. While that might not sound very “low cost” to some, especially compared to a $2,495 urban electric motorcycle, that’s practically pennies in the world of full-size electric motorcycles. Consider that the new Zero SR/F starts at well over twice that, and Harley-Davidson’s upcoming LiveWire is over three times the price of the Zero FXS.

    Its top speed is 137 km/h ...  more

    Rice University Researches Develop Nanotubes That Can Increase Solar Panel Efficiencies from the current 22% to a potential 80%

    As it stands, any hot surface emits light in the form of thermal radiation. But Naik said the problem is the thermal radiation is broadband. In order to convert light into electricity, the emission has to be in a narrow band, and thus the invention. The researchers discovered nanotubes are a way to isolate the photons that would be wasted. The nanotube films act as con...  more

    Hydrophilic disc uses solar steam generator to separate salt from water

    One problem with desalination is that the salt tends to gather on the surface of the material, which makes it difficult to produce pure water. The Monash University researchers worked around this problem with an intricately designed solar steam generator that prevents the salt from spoiling the broth. It consists of a disc crafted from super-hydrophilic filter paper, a material that attracts water, which is coated with a la...  more

    'How much car do you really need?' - the tiny Microlino EV hopes to drive future mobility

    We may ask, how much car do we really need? A Swiss start-up's answer: The Microlino - electrically powered, inspired by bubble cars from the 1950s. It's a building block for future urban mobility but how useful is it really? According to the automaker: "Imagine a world in which you can fit into any parking spot. With the Microlino you can do just that and more: due to its size it can cross-park and theref...  more

    My 2,6kW solar installation running at up to 2,4kW so far in mid-winter and providing 11kWh for the day

    The new system is running the whole house except for the geyser (which is on a Geysewisde timer system). Although it is the middle of winter and the days are short, a sunny day is generating about 11kWh and the system is maxing at about 2,4kW by midday. I'm looking forward to summer when our days are far longer and sunnier. Right now I'm getting about 60% of the daily consumption from solar.

    Another Electric Vehicle Benefit: No Direct Exposure To Cancer-Causing Benzene - especially for workers at gas stations

    The World Health Organization, an international public health agency associated with the United Nations, has written this statement about the chemical: “Benzene is a well-established cause of cancer in humans.1,3 The International Agency for Research on Cancer has classified benzene as carcinogenic to humans (Group 1).1,3 Benzene causes acute myeloid leukaemia (acute non-lymph...  more

    California replacing 200 polluting diesel school buses with all-electric buses - study published in Economics of Education Review last month showed diesel retrofits had positive results on both respiratory health and test scores

    A study published in Economics of Education Review last month showed diesel retrofits had positive results on both respiratory health and test scores. Eliminating emissions from these buses completely will do even more to protect children from dangerous emissions while ...  more

    My solar installation generated half of my daily consumption yesterday (10.91kWh) and peaked at 2116W

    It's only been in two or three days now but is averaging 10kWh generation per day (we are still in Winter but days are short and sunny). Batteries were fully recharged by 2pm. I need to play a bit with the battery state of charge limits and am running them down to 60% for now. The geyser is not running off solar but everything else is until the battery state of charge falls to 60% during the ni...  more
