I hope that the new upcoming Tesla model 3 also supports CCS charging (in Europe). This will enable Tesla to use 350 kW charging in the (near) future.

Many LED manufacturers exploit the flaws in the way how the CRI value is determined to get a high CRI value for their still poor performing LED lamp regarding color quality. The CRI is purely used a marketing instrument and is not a reliable indication for color quality when applied for LED lights.

Our sun, a nuclear fusion source which is already working reliably for more than 5 billion years, produces an extreme amount of energy. Within 6 hours, deserts on Earth receive more solar energy than we use in a whole year globally. Why do we keep ignore this most power full energy source? For the world energy demand (18.000 TWh) we need only a surface area of 188 x 188 square miles with Concentrated Solar Plants. This is a small thumbnail on the map of Africa. Germany has seen the light and is investing 500 billion euro's in Desertec. A CSP plant runs 24 x 7 hours on full power (even when the sun is away because it can store sun heat in molten salt). These CSP plants can easily replace nuclear and coal power plants.

Why is that? The current (single) battery in any car is already standardized (form factor and voltage) and can be switched easily, why not introduce these standards for full battery packs?

One could imagine a standard battery pack standard for small, medium and large cars. Another option would be that smal cars needs a single battery pack, and larger cars need more. Similar to small batteries like AAA, AA, D, etc...Some devices only need one battery, some need 8 batteries.

If electric car manufacturers standardize their battery pack on dimmensions and voltage output this will create huge benefits:

• Swapping batteries either automatic or manual is easy
• A new market will be created for companies providing improved batteries which can be used in any electric car
• Cost down by mass producing the battery packs

I have good experience with Scrumworks for planning the development work using Scrum, Trac for PR/CR management and Subversion for source control.

I would suggest to look at Agile Software Development and planning tools. These are lightweight and highly effective, especially in constant changing environments (read requirements).

On the Renewable Energy website OliNo there is an article Test results small wind turbines website with some more background on this test. The first test results show that a PV system (Solar Energy) is more cost effective than these small windturbines. The Dutch article, which is more up-to-date, show also the last measurement results of the windturbines (11 months of data). The conclusion is the same. However, it was found out, that an official wind measurement station of the KNMI only 14 kilometers (8.8 miles) away form the test site has an average windspeed which is twice of of the test field. This could explain the low yield of the windturbines.
