Electric Aircraft

.

There have been some very interesting recent developments in the area of electric aviation:


Battery-electric technology:

Note: future developments include on-board fuel-cell power generation for battery recharging. In essence, it's a range extension device.

This is a one-seater aircraft built from the ground-up!


Solar Technology:

This solar powered aircraft has the benefit of unlimited flight during daytime hours.


Extra simplified comparison of the 3 aircraft:


These 3 aircraft were only a small sample of the EV aircraft that have been studied and tested.

We have gone from NASA high tech aircraft to private individuals developing their own personal concepts of electric propulsion aircraft.


We are perhaps witnessing the shift of aviation to a slower, more sustainable mode of transportation?

...only time will tell...

ADDICTED TO PLASTIC

.
Ever wonder about what happens to plastic after we simply discard it?

The answer would very much surprise you...



I had a chance to view the documentary "ADDICTED TO PLASTIC" and what it had to say was not only quite disturbing, but also cautiously optimistic.

In short, the last 100 years of plastic production and development have produced some fantastic materials that are specifically tailored for specific applications. Each one of these materials are extremely durable... but that's the problem... they simply don't go away! These materials are forever with us, and we don't have to look far to see the effects of the tail end of this life cycle.

It's not only possible that we're creating a real mess in the environment, but that we're also polluting the food chain in the process, toxifying ourselves without realizing it.


BUT there are some people trying to do something about this. We are looking at recycling and re-manufacturing existing materials from both current and discarded (garbage) sources. There are other people currently in the process of re-defining and re-engineering acceptable parameters for the manufacturing and production of traditional plastics; these parameters include thickness, chemical composition and the ability to reuse and recycle, or close-loop these materials.

The most interesting development is the introduction of bio-plastics. These plastics are from food sources such as corn or starchy materials and can be engineered to decompose in UV or completely disintegrate on contact with water.

These are absolutely fascinating developments...

I challenge you to view this film... It will get you to stop and think about who we and what kind of a mess we are capable of creating when we lose sight of global environmental responsibility.


Plastic is necessary, but it's time to shift gears and take this game to the next level.

The art of closed-looping existing systems and the current development of bio-plastics are a sure sign of the times....

Here comes the future!
