What are your ideas for eco-friendly projects or inventions?

I am working at a green design company that is looking for new ideas. These could be ideas for buildings, for products, or for projects. Basically, any idea that seems good, but requires some engineering or design work. Our selection criteria include aesthetics, affordability (we are looking for things "for the masses", not things for the super-rich), and environmental sustainability.

The ideas are all out there - they just need to be put into practice.

Solar power, wind and wave power. Green housing, more tree planting (grant aided) for the use of everybody including birds, insects and people. This would include picnic areas, barbecues, camping sites, bridges, ponds etc.

What are your ideas?

Are there studies about converting plastic bags into durable, weather-proof blocks for the construction industry. That would get rid of a lot of plastic waste.
