Green Cars Part 3- Hydrogen

Posted 02-03-2009 at 01:14 PM by mattW

The more I delve into this topic the more detail I want to address, so rather than cover all three energy storage options in this post Iíve decided to give a more detailed look at hydrogen. Keep a look out for a look at compressed air and battery electric in the next two weeks. Hydrogen is the darling of the media, car manufacturers and oil companies alike. The general public seems fairly convinced that hydrogen vehicles are going to be the way of the future and a simple replacement for oil. Just...

Lithium vs Lead; the Great Cost Debate.

Posted 02-03-2009 at 01:21 PM by mattW

I've decided to try and work out the cost comparisons for a Lithium pack vs a Lead pack for a set range and a set number of years. Is Lead Acid actually cheaper or does is just seem that way up front? This article aims to find that out. The method is to get 10kWh of usable energy, Iíll try to get that with Lead and with Lithium and see what we find is cheaper in the long run. Assuming an efficiency of 250Wh per mile (a compact car) we should get a range of 40 miles (65km) with either pack. Iíll...

Step 1: How to plan a DIY Electric Motorcycle

Posted 02-03-2009 at 01:34 PM by mattW

Last week I said that this blog would be part journal, part guide to the conversion process but I've decided to separate those two categories by having a build thread for the bike with pretty pictures and having this blog as a sort of step by step guide. I'll still give you updates here but primarily the build thread will be about how I'm doing it and the blog will be about how you can do it. Step one in that process is making your plans, what do you need to know in advance before you start in order...

Hello All,

Found a great little download that has a bunch of great electronic tools. Electronics Assistant is a Windows program that performs electronics-related calculations. It includes a resistor colour code calculator, resistance, capacitance and power calculations and more. Details of calculations can be saved or printed. It provides all the functions found in the calculators section of this site and more in a stand-alone user friendly program.
