Lucid Energy turbines

Lucid Energy is running electricity turbines from the water flowing in the pipes of a city.

This provides baseload power with no emissions, and the technology can be retrofitted into any water pipe large enough.

Most drinking water pipes in most cities of the developed world can use this technology!


#Solar power changing the face of poverty in India

Large, corporate power suppliers often cite baseload [the amount of energy needed to satisfy the minimum energy demands of a given society] as the reason for dismissing solar power. Solar panels/arrays don’t work at night so solar must be useless for baseload.

On the surface, the need for baseload power does appear to leave solar out in the cold, but…all baseloads are not the same. In India, there are tens of millions of people for whom baseload equates to just one light bulb. These are the people living in distant rural areas, or city slums, or simply on the pavement. They are poor in a way we in the West cannot even imagine because, despite their poverty, they have to spend a significant portion of their tiny monthly incomes on kerosene for their lamps, or batteries for their torches. All because they are too poor to tap into the electricity grid.

And this is where Piconergy comes in. Founded by a group of young, well-educated, clever young men, Piconergy has created a super small-scale solar power plant called the Helios [from the Greek word for ‘sun’]. This is the product description from their website:

Product Features

–  Strong and sturdy Power Box which can be easily carried around and/or wall mounted, housing our battery management system & a 6V 4.5 Ah Absorbent Glass Mat (AGM) technology based sealed maintenance free battery.

–  5 Watts-peak Solar PV Module with 4m cable & connector.

–  Three LED Light Bulbs producing up to 200 lumens each with 3m cable & switch to cover maximum area for illumination.

–  USB port for charging mobile phones.

–  Optional SMPS Adapter to charge battery from grid supply.

And this is the product:

Piconergy are making the Helios available to families in the slums of Mumbai:

  • so the children can study at night,
  • so cottage industries can make more products to sell,
  • so families do not have to live in the dark

I cannot tell you how much the dedication and commitment of the young men at Piconergy warms my heart. They are not just talking about social inequality, they are doing something practical to help. But my admiration for them goes beyond questions of social conscience – I want a Helios for myself!

Why? Why would a middle class woman in Australia with solar panels on her roof already want such a small-scale solar device? I’ll tell you why. I want my own Helios because the solar panels on my roof are tied in to the grid. When the grid goes down, my solar panels are turned off as well. In a word, they become USELESS.

I cannot tell you how many times we have sweltered during a 40 degree day because the grid was down. No aircon, no fan and no landline telephone. If our mobile phones aren’t charged then we are literally isolated from the outside world. And then there are the nights when we need torches and candles just to get to the bathroom. Again, because the grid is unreliable.

After the fire that destroyed homes south of the river a couple of years ago [in Warrandyte], SP Ausnet is finally putting in heavy duty powerlines and some underground cabling, but for now we continue to lose power, and I continue to keep torches and candles dotted throughout the house.

For us, the potential for sudden, energy poverty is very real, and I intend to do something about it. More on that later.

For now, though, if you care about those less fortunate than yourselves, may I suggest you give Piconergy a boost in social media. After all, ‘Mighty oaks from little acorns grow.’

Australia, #solar panels and #directaction

The current Liberal government tries hard to sell it’s Direct Action policy on Climate Change, but apparently all that Direct we-give-you-money-to-create-less-carbon rhetoric only applies to big corporations. Incentives for small scale solar, wind and thermal brought in by the previous Labor government have been slashed, perhaps because they worked too well.

The history of small scale energy generation began in 2009 when Labor used a kind of small ‘d’ direct action policy to encourage private individuals, community groups and business to go ‘green’. Not only would we receive a generous rebate for the cost of the energy generation systems we installed, those systems would then be connected to the grid and the excess energy they generated would be sold to electricity retailers! Win-win.

This description of the Premium Feed-in Tariff is taken from the Victorian government’s own website:

The Premium Feed-in Tariff (PFIT) started in late 2009 and closed to new applicants at the end of 2011.

The scheme offered eligible households, businesses and community organisations with small-scale solar systems of five kilowatts or less a credit of at least 60 cents per kilowatt hour for excess electricity fed back into the grid.

More than 88,000 Victorian households, small businesses and community groups are now benefiting from the PFIT.

60 cents per KWH. That’s more than twice what we were paying the retailers for electricity back then, and those lucky enough to join the scheme during this initial phase will continue to receive 60 cents per KWH until 2024.

Then, from December 2011 to December 2012, small scale generators were offered a reduced tariff of 28 cents per KWH. This was more or less on a par with the cost of electricity generated from coal.

But from January 2013, the FIT plummeted to 6.2 cents per KWH. Now have a look at this pricing schedule published by Origin Energy:

origin electricty pricing

So let’s say you’re on the Residential 5-Day Time of Use plan. From 7:00am to 11:00pm, Monday to Friday, you will pay 39.732 cents for every KWH you use. But any electricity you generate and feed into the grid will only earn you 6.2 cents per KWH.

Yes, your eyes did not deceive you – your electricity created no carbon, but it is worth 6.4 times less than the dirty stuff produced in the La Trobe valley.

Proponents of coal-fired power say that solar, wind and thermal are no good because they do not provide baseload energy, but what exactly do they mean by that?

As I understand it, baseload energy is essentially the capacity to produce the minimum amount of energy required during a 24 hour period.

At the moment, baseload power is provided by coal fired power stations that are belching out carbon pollution at peak capacity, all the time, because:

  • it takes so long to get them going, and
  • it’s cheaper to run them full on, all the time

There are other energy production systems that are more flexible, but they tend to be more expensive to run. Here in Victoria I believe we rely almost exclusively on coal fired energy.

Now, while it is true that green energy is produced at the whim of the elements, and hence not completely predictable, it can reduce energy consumption at the local level. In fact, the installation of solar panels on roofs since 2009 has reduced demand for baseload energy. So why isn’t it being valued? And why aren’t governments bending over backwards to get more of it?

The problem, essentially, is a clash of cultures. At the moment, coal is king because the operators of coal fired power stations do not have to factor in the cost of the pollution created by that coal. If pollution became a cost like any other, a number of interesting things would happen:

  • the price of energy would go up in the short term,
  • everyone would scramble to minimize their use of this expensive energy source
  • and new technologies would spring up to make other energy generation systems more cost efficient – this would include not only renewables but also batteries capable of storing energy produced from all sources, including coal. [Because coal fired power stations run at full capacity all the time, much of the power they produce is actually wasted].

Unfortunately, none of this is likely to happen in the near term because we are still only paying lip service to the problem of Climate Change. Once the $hit hits the fan, things will change in a hurry, but it won’t be efficient change, and all the forecasts suggest it will be a LOT more expensive than voluntary change now.

So in terms of you and me, are solar panels worth doing any more? From a purely financial perspective, probably not. 😦 You will still save some money off your energy bills by using your own energy, but the truth is we all use more than we generate, and it often tends to be at times when solar is not available [e.g. at night]. So then you have to balance up the savings against the cost of the solar panels and their installation…

When I installed my solar panels and solar hot water, I hoped to have everything pay for itself in about five years years. Not gonna happen, folks. I started out getting the 60 cents per KWH then a strange administrative ‘blunder’ meant that the paperwork proving I’d joined in time disappeared. Now I’m on 28 cents per KWH but apparently that will only last until December 31, 2016. After that I’ll get next to nothing.

Am I bitter? Yes, I am. The Liberals are going to give large corporations lots of money for doing the wrong thing while I am going to lose money for doing the right thing. I really truly wish the Libs would throw some of that Direct Action loot in my direction for a change. 😦
