Open source electric cars?

Is it possible to use open source principles into building electric cars? It seems like it is. Electric Cars - Now! movement (based in Finland) is running a project which allows you to convert your everyday fuel powered car into Zero Emission Vehicle. All the software, blueprints and assembly instructions are provided as open source, free for everybody to use.

They currently have a working prototype called eCorolla (that I happened to see when the false fire alarm drove me to the yard of Innopoli earlier today) based on Toyota Corolla that can drive up to 150 km with full battery. The price for conversion kit is about 20 000 EUR. The lithium batteries are currently the most expensive piece. The price of batteries is expected to drop when the production lines of battery producers ramp up with the demand in future.

Payloads with Lucene/Solr

Grant Ingersoll has written a nice post about using payloads with Lucene/Solr.

Grant gives an introduction on what payloads are, shows how they are injected into Lucene index and finally how stored payloads can be used to score documents. Very nice post!

Yahoo! is not offering any support for their releases but they expect companies that are specialized in Hadoop to take care of that part.

54% of organizations in Finland use OSS

According to TNS Gallup (on behalf of Sun) 54% of organizations in Finland use Open Source Software. OSS penetration is high in all of the the Nordic countries (Finland, Sweden, Norway, Denmark) with average of 46%.

Sun believes that the increased demand for open source in general is driven largely by the global economic downturn. I am pretty sure the trend of OSS adoption will keep going north even when the economical situation gets better.

Marc Krellenstein has written a nice post about the myths of open source software that might help you to decide your policy about using Open Source (Search) Software in your organization.
