Remember where you are from. You’re from Earth.

Demonstrating “all” is difficult. Most of the time, the climate doesn’t follow our dire predictions. The date arrives and the apocalypse doesn’t happen.

This is why so many movies (2012, The Day After Tomorrow) depict two things

1. The disruption is happening faster than predicted.
2. It’s happening to nice, educated, relatable white people, not to strangers far from us.

Hence drama ensues. But this is a movie, right?

The reality is that it will be slightly slower than predictions but it will be uneven. Entire regions populated by people who don’t look like you will be devastated by floods or hurricanes. Meanwhile you’ll complain that the summer was a bit rubbish (or in sailing circles that the westerlies and trade winds patterns are changing).

The locations hit worst will be places that you like to go on holiday or regions which make your products cheaply.

But it doesn’t have to be like this.

Providing developing countries with modern technology (such as solar) in sufficient quantities could change them from being a carbon-producing economy into a carbon neutral economy. The impact of that alone could be massive – China already has realised that their rapid industrialisation has had a negative impact and they’re taking steps to produce more solar every year than most countries will ever install in a lifetime.

We have the technology to create a future-proofed 22nd Century civilisation. But like climate disruption, it is applied unevenly.

The negatives of globalisation can be turned into positives if we remember that we all live on the same sphere (the pale blue dot) and that what happens in London or Mumbai or Durban will have an effect on lives in Shenzhen, Helsinki and Melbourne.

Remember this when someone asks you where you’re from.

You’re from Earth

Solar…portable…renewable

Anyone who knows me will know that I’ve always been a fan of solar (photovoltaic) energy production.

Anyone who knows me will know that I’ve always been a fan of solar (photovoltaic) energy production. This goes from tiny little solar panels that I used with Coder Dojo to wire up fans and LEDs to larger scale panels that are used to keep my phones and other devices charged when out and about.

My latest purchase is the Anker 14W Solar Panel Foldable Dual-port Solar Charger.

I was pretty pleased with the package – it was smaller than I expected and seemed sturdy enough. It fits neatly into my hiking backpack when I’m not using it and when I am using it, I’ll tie it using cords to the back of the back – the built-in rings seem very resilient. The company advises using the included pockets for holding devices you’re charging (to keep them out of the direct sunshine). I’d like them to be a little bigger but that’s only because my devices are a little bulkier.

Anker14WSolarCharger

I tested this during the week in some weak summer sunshine here in Northern Ireland and I was able to generate nearly 7 Watts (5.09 Volts, 1.35 Amps). That’s about 50% of the potential output of the panel but considering I was just sitting in a park with plenty of surrounding tree cover, no effort being made to optimise the angle and a little bit of cloud cover – coupled with the weak Northern Irish sunshine – I was happy to see I could easily power and charge a phone.

Your phone likely needs 5 Watts of Power (5 Volts, 1 Amp). The average PC USB port outputs 2.5 W (5V, 0.5A). Your iPad needs about 12 W (5.1V, 2.1A). The device I’m using to measure this is a pass-thru USB power monitor by PortaPow. It can check any USB port for power output and is cheap as chips. For the aspiring geek it’s a useful informational tool.

I’ll be using this panel to charge an Anker 13000 mAh portable battery (superseded by newer models like the Anker Astro e7 with double the capacity). 25600 mAh seems like a lot but the iPhone 6 has a 1810 mAh battery and therefore I’d expect to get 10 charges out of this. Which should be good enough for a week of outdoor usage (assuming I’m using the screen a lot).

Next week I’ll be testing the charger in Southern Spain. I’m interested to see what the difference in throughput will be and how fast it will charge my external battery.

My reply:

Phones don’t have carbon footprints. People do. When I’m using my iPhone I’m not using my MacBook Pro which has an 85W Power Supply.

It may seem crazy but this is an example of doing more with less. When I’m doing stuff on my iPhone (playing a game, tweeting, sending email, browsing the web), I’m not powering my MacBook Pro with it’s 17″ screen, dual core processors and kick ass graphics card – any one of which is likely to exceed the entire power drain of the iPhone.

My MacBook Pro has a 68-Watt-Hour battery holds 244800 (68 x 60 x 60) watt-seconds which equals 244800 joules. It drains in just under 4 hours of normal usage.

iPhone has a 1400 mAhour 3.7V battery. This means 1.4 Ampere-hours at 3.7 V. If the voltage remains constant (which is the real trick), this converts proportionally to Watt Hours so 3.7 V x 1.4 ampere-hours = 5.18 Watt Hours. Which means it holds 18648 joules. It drains in around 5 hours of normal usage (meaning constant usage. Standby is much better)

Can someone who knows a bit more about power check my figures? Being conservative with my power is important to me. (Point being that I recharge my iPhone using solar collectors – difficult enough in Northern Ireland)

Having a ready source of energy is important to someone who finds himself more often than not out of the office.

More on battery power.

I get about 2/3 of a day out of my iPhone battery. Guy Kawasaki recently explained how to lengthen your iPhone battery. Turn off a load of stuff. Balls to that. I have two phones. An iPhone 3G which lasts about 8 hours. And a Nokia 6300 which lasts about 3 days. Strike one for … Continue reading “More on battery power.”

Balls to that.

I have two phones. An iPhone 3G which lasts about 8 hours. And a Nokia 6300 which lasts about 3 days.

Strike one for Nokia. Er, no. Because the only thing the Nokia actually does is sit there and do nothing. The iPhone is constantly downloading twinkles, grabbing email every 15 minutes (and receiving email pushes constantly) and footering with the GPS.

So it lasts 8 hours. Buy a PowerMonkey and get over it.

Nomadic Power

One half of the issues of being ‘Bedouin’ is the relative scarcity of net access. There’s heaps of WiFi out there, 3G and EDGE connections but every now and then you find yourself bereft of networks to attach to, for instance, in the middle of the North Sea. You can still work especially if you … Continue reading “Nomadic Power”

One half of the issues of being ‘Bedouin’ is the relative scarcity of net access. There’s heaps of WiFi out there, 3G and EDGE connections but every now and then you find yourself bereft of networks to attach to, for instance, in the middle of the North Sea. You can still work especially if you have a laptop with you and even if you’ve just got your iPhone or other ‘relatively smart’ phone, you can hammer out some ideas, prepare some emails to be sent when the network returns or do those boring jobs which you’ve been putting off.

Power, on the other hand, is a must. It’s not usually a problem at home or in the office but what do you do when out and about. First thing is to look for any power sockets you can find – it’s worthwhile noting where they are in cafés (and on the Ferry/HSS). Not surprisingly, most vendors take a dim view of plugging in even if you’re a paying customer.

So what do we do to deal with that? I’d blogged previously about The FreeLoader but I’ve added to this with a third party battery booster (which provides ONE good charge for an iPhone) and also a PowerMonkey eXplorer.

Check this out. A charger that can harvest enough motion from walking to replenish cell phones or other small gadgets, like GPS devices. It says that six hours of cumulative motion can add 30 to 60 minutes of talk time to a cell phone. The idea is to place the charger inside a purse or backpack and let it charge in the background

I’ve been comparing the iPhone 3G to my Nokia N82 and N95 and my Microsoft Mobile-powered Samsung Blackjack II cell phones and, again, the iPhone kicks ass.

I’d have to agree, the iPhone 3G does kick ass. Is it considerably better than iPhone 2G? No. It’s not really but the upgrade was a no brainer for existing iPhone users in the UK – it was like getting an iPod touch for free mid-contract. My old iPhone is sitting, SIM-free, for use as a development machine and part time iPod touch for the time being.

Issues for the future though – I drained my battery in much less than a day. I was using 3G and GPS a lot so that’s to be expected but between 10 am and 4 pm, the iPhone battery became seriously depleted. I’m glad I have a Solar powered FreeLoader.
