has come up with a wastewater treatment plant that sucks out materials
from wastewater and some of these removed products can be consumed as a
diesel additive. It depends on what's in your wastewater, but Nowa CEO
Richard Nelson says you find the fuel there quite a bit.
You can mix it 50-50 with diesel and get about the same amount of energy as pure diesel, according to Nelson.
Water remains one of the growth areas in clean tech, but it doesn't
nearly get as much focus as biofuels and solar power. One of the fears
about the water market is that the main customers are slow-moving
municipalities
That's a misperception, asserted Jeff Green, CEO of NanoH2O, a
desalination company that grew out of research at UCLA; 70 percent of
the water that gets used goes to agriculture while 20 percent goes to
businesses. Many of these companies have their own private purification
systems.
"We are trying to make desalination competitive," Green said.
In urban centers, water sells for around 25 to 50 cents a cubic meter.
Water run through standard desalination processes sells for 50 cents to
$1 per cubic meter. Nanotechnology and new membranes will bring the
price down, he said.
Another interesting water company at the show is WaterLink
Systems, which studies weather patterns and conditions and releases
irrigation to farmers accordingly. One of the company's systems, bought
by industrial water uses and agribusiness, can save up to a million
gallons annually, according to CEO David Chacon.
The company actually grew out of the Three Mile Island nuclear
disaster, said Chacon. After that debacle in 1978, two scientists tried
to come up with a system that would use meteorological data to help
rescue crews get people out of dangerous areas.
