I was making some updates to the ‘Our Technology‘ page and realised how out of date and incomplete it was.

For instance it didn’t mention Megan’s new grocery shopping list (aka Ipaq H4100), our cameras or phones.  Plus I added a new section ‘future’ which comprises technology I’m planning on buying in the future (when budget becomes available)…

As only someone who understands my crazy daydreaming mind would understand, I ended up finding a use for Wolfram Alpha.

I wanted to know the amount of time it would take to fly this plane from North Shore Aerodrome to Lake Whakamaru at the cruising speed of 135 knots so that I could work out how much fuel it would use and subsequently how much it would cost….

So I put in 275km at 135 knots into google and failed. I tried the same thing with Wolfram Alpha (thinking I might have finally found something it could do) and bingo!.  Just over an hour.

For those who are interested, the plane burns 40 litres of fuel per hour when cruising.  Assuming slightly more for takeoff, at 66.92 cents per litre (for Jet A1 apparently) then this would be $33.46 one way.  Seems like a bargain if you can afford the $140k (plus GST) pricetag of the plane and the no doubt horrendous costs of storage and maintenance for a piece of airborn machinery built a decade before I was born and just a few years after the moon landing.

I’m sure you’ve all noticed that I have a fair amount of advertising on my blogs.  It’s not really an attempt to make my millions, but is an attempt to cover the costs associated with running and hosting your own sites and email.

In the past I’ve successfully managed to cover my costs, but I’ve noticed over the last few months that I’ve been selling almost nothing, despite site visits remaining relatively stable (and in the case of sapdup growing significantly).

You can see below that while there were some low months previously (where it spikes down to close to 0), the low run over the last few months is unprecedented (I have data going back further which looks similar).

So, given I’m blaming the drop on the recession, could it be that a sign the recession is turning around could be seen in an upturn in my ad revenue?  While my sites are a very small subset, I believe this general hypothesis to be true.  So I’m going to be checking back in the first week of each of the months this year to see whether we’re seeing any ‘green shoots’ coming through my ad revenue.

Note: At the end of June I added a new ad supplier.  This increased revenue by about 11 cents in June and is tracking to increase revenue by about 50 cents in July.  But until we see an economic recovery, no provider is going to be able to meet the revenue figures of >$10 per month which I saw frequently in 2007 and 2008.

After reading this review, you may be interested in two other related posts:

Powershop Review – 1 Year On
Powershop Review – 1 Month On
Powershop Outgrows All Comers

After a love-hate relationship with our traditional power supplier (Genesis), ok mostly hate, we decided to make a move to the very non-traditional power supplier, powershop.co.nz.

Now, let’s not delude ourselves.  Powershop is not a small, innovative startup out of someone’s garage.  It’s fully owned by Meridian which is something that put me off at first.  Meridian has (at least in my view) an image of a ‘green’, ‘premium’ power supplier.  So my first thought was that there was no way I was going to be able to save money moving from probably the least environmentally friendly company (I think they run Huntly) to in my opinion the most environmentally friendly.

But what I think is going on here is what should be, considering the way the power grid works.  All the generators put their power on the grid and anyone can pull it off.  So there is no such thing as ‘green power’ for the consumer, only people who are willing to pay more to support ‘green generation.’

This is basically the way Powershop works, you can buy the budget power which isn’t really green at all.  Or you can pay more and buy the ‘green’ stuff and theoretically support the greener sources of power.

So I think I can make a saving.  Only time will tell.

So, first impressions.

(1) No connection charge.  I was going to switch to Trustpower, and they were going to charge me $30 for the privilege.  Instead, due to a promotion which Powershop were running, I actually got a $30 credit.  Sweet.

(2) High startup costs.  This isn’t Powershop’s fault, but a result of the model.  We were paying in arrears with Genesis (i.e. you use the power and then they bill you for the month’s use (in our case about $200).  But since you pay in advance with Powershop (i.e buy your power and then use it) it makes for an expensive switch over period.  For example we paid our bill till 12th June of ~$200 in our current credit card period.  Then the switch happened and we’ve been billed for a period between the 12th and the 2nd of July which came to ~$150 which will be paid for on the same credit card bill.  To get us till the end of the current credit period, I think we’ll have to buy about $70 worth of power from Powershop (including our credit) so this means instead of paying $200 for our power this month, we’ll be paying $420, a bit of a dent in a tight budget.

(3) Functionality looks like it will be cool, but only one of the graphs (daily use) is active until after the first month (presumably).  I like being able to enter your actual readings and see how this effects your credits.  It would be cool if this could somehow be linked to our actual meter in the future (smart meters?)

(4) There’s not much range of power purchasing options.  They have a vision to get other providers in on the system (i.e. genesis could try to win back my purchasing) but until they get many more users, I can’t see this happening.  I also think that their ownership structure inhibits this.

That’s all for now, watch out for the next edition.
