    SAA business rescue plan in deep trouble

    There are several privately operated airlines to chose from who offer flights at cheaper rates and without requiring tax payer bailouts to stay afloat. SAA is not an essential service. What service is SAA providing that the other operators can't? Free flights for the politically connected?

    WACS cable break - Slow SA Internet speeds

    How likely are those scenarios compared to our undersea cable breaks? :rolleyes: The satellites are only designed with a maximum service lifetime of 5 years so SpaceX will be continuously launching new Starlink satellites as the old ones are removed from service. It's like a self-healing...

    WACS cable break - Slow SA Internet speeds

    Space X's Starlink system is starting to make a lot of sense compared to terrestrial fibre links especially for third world countries and remote areas. No undersea or last mile fibre cables which can be dug up or broken So much redundancy that if you lose a dozen satellites it makes little...

    Government to scrap civil-servant pay increase

    The lowest salary in the public sector is over R10000 per month. https://m.fin24.com/Economy/12-numbers-that-put-the-public-wage-debate-in-context-20200304

    How to Size li ion battery for a solar system

    Yip, definitely Lithium based batteries. Lead acid batteries are a waste of money over the long term. I have one of those old disc meters which probably runs backwards so if I was starting out in solar I'd get just enough battery capacity to handle load shedding and add enough solar to keep my...

    Government to scrap civil-servant pay increase

    So we should rather borrow more money to keep dishing out CPI+2% increases instead? Where is the money going to come from? The private sector is practically broke already. We wouldn't manage to claw back even R10 billion from corrupt cadres nevermind R160 billion so that is not a feasible option.

    Government to scrap civil-servant pay increase

    The strikes will be cheaper especially if the government grow a pair and enforce "no work no pay" with no back payment option. If public servant wages keep increasing by 5 or 6% every year but GDP and tax growth are near zero we'll soon end up like Zimbabwe were 90% of all taxable income is...

    Government to scrap civil-servant pay increase

    The private sector and small business in particular are battling to survive. Take a look at how few companies actually pay corporate income tax because they're barely surviving. Just a few large companies are keeping South Africa afloat. It's going to be interesting to see what happens after we...

    Government to scrap civil-servant pay increase

    If the agreements are honoured then only the people working in the private sector are going to be tightening their belts. Put another way, people in the private sector are often getting zero percent or below CPI increases in order to subsidize public servant's CPI + X% wage increases. Now that...

    Government to scrap civil-servant pay increase

    The same innocent people who saunter into offices when they feel like it, walk out for extended lunch breaks in the middle of serving a tax payer, joining union led strikes which involves general destruction like burning tires, over turning dust bins, etc. when it comes to wage negotiations? The...

    How to Size li ion battery for a solar system

    That applies especially for off-grid installations. If one is able to feed back into the grid (not many options for this in South Africa yet) then it makes sense to size your battery capacity as small as possible (backup only) and beef up the solar side in order to reverse the power consumed...

    How to Size li ion battery for a solar system

    Battery capacity is only one part of the equation. Make sure that you don't exceed the continous max charge and discharge rates for the batteries. e.g. The max recommended continous discharge rate for the Pylontech US3000 is 37A. A 5kW 48V inverter will pull up to 104A at max capacity so you'll...

    SAA business rescue plan in deep trouble

    Good stuff! Shut it down. Another R5.5 billion wasted in 3 months which the tax payer will have to foot.

    Oil plunges 30% after Opec deal collapses

    Many investors thought the same about Zimbabwe's stock market. Also stock is worthless if the company does not survive the bad times and liquidates.

    Move from 2 electric geysers to a single Solar geyser

    Just remember the higher the temperature the less efficient the collectors become due to thermal loses. Also flat plate collectors aren't as efficient as evacuated tube solar collectors. My three flate plate collectors get 300L up to about 65 degrees on a hot day or low 70s on a scorching day...

    12V Battery charger options

    The Optimate 5 max charge current for 12V batteries is 2.8A which is just a bit on the high side for a 7Ah battery but it depends on the battery type and specs can handle. Charging sealed AGM and GEL batteries at too high a current can cause problems because they're not open cell sp gassing...

    Soweto residents want to pay R150 per month for electricity

    No, it is not fair. They can use as much electricity as they like for R150 per month? If each household uses 2000kWh per month but only pays R150 the cost to produce the electricity is still born by Eskom and eventually the tax payer subsidizes it at the end of the day. You will not believe how...

    'Electricity is a right and we must not pay for it': Andile Mngxitama on Soweto shutdown

    Amazing! One just needs to burn coal to produce electricity. I burnt some coal in my braai while there was load shedding but the lights in my house didn't want to turn back on. What am I doing wrong? Is it maybe not working because I paid for the coal instead of using free coal?

    Gauteng shutdown - Soweto wants free electricity

    It's the exact opposite! Free electricity means they have no concern about energy efficiency. i.e. 60W or 100W light incandecent light bulbs, leaving a bar heater on in each room during the day so when they get back home after work their houses are nice and warm, etc. Just talk to some...
