Energy-harvesting Cranes Cut Down on Fuel Used at Ports

An innovative crane system allows cargo ports to dramatically cut the amount of diesel fuel they use to run generators.  The REGEN system by VYCON Energy uses a flywheel to capture energy from the how to get levitra lowering of shipping containers.

A typical crane runs on a 500-800 kW generator to lift and then control the lowering of multi-ton containers.  During the dropping of it's cool best online levitra the container, the motor to runs in reverse, a situation where power could be generated, but is typically expelled as waste heat.  The REGEN system capitalizes on cialis sale buy this lowering part by absorbing that energy with the flywheel and feeding it back to the crane to be used immediately for the next lift.  This allows the we choice how does cialis work port to use smaller generators and, thus, less diesel fuel.  Ports that have installed these systems have seen 30 - 45 percent reductions in fuel use.

The flywheel has a lifetime of about 20 years (no batteries to replace) and the company offers an installation kit for both existing and new cranes.  The systems cost $120,000, but return on investment has been in about three-and-a-half to five years, which is pretty great for any energy-saving technology.

The systems are in use in China, Japan and other spots in Asia, and a lobbying group has formed in California to secure government money to install the online viagra experment systems there.

It makes you wonder, what other industries are missing the chance to 100 mg levitra generate energy from gravity?

3.5 to 5 year return on investment - using the "Rule of 72" we can discover that installing this equipment is the equivalent of investing ones money at a 14.4% to 20.6% interest rate.

With today's loan rates any company would be foolish to not buy in.

But, great as it is, it's not the best way to increase the we recommend next day viagra bottom line for many businesses...

Dow Chemical’s Louisiana division.

You might have predicted that by 1982, after two major energy shocks, if any company in the country had captured the low-hanging fruit of energy savings, it would be one as energy intensive as a world-class chemical manufacturer. Nonetheless, energy manager for the division’s more than 20 plants, Ken Nelson, began a yearly contest in 1982 to identify and fund energy-saving projects. His success was nothing short of astonishing.

The first year had 27 winners requiring a total capital investment of $1.7 million with an average annual return on investment (ROI) of 173%. After those projects, many in Dow felt that there couldn’t be others with such high returns. The skeptics were wrong. The 1983 contest had 32 winners requiring a total capital investment of $2.2 million in a 340% return – a savings of buying levitra online canada the company’s $7.5 million in the first year and every year after that.

Even as fuel prices declined in the mid-1980s, the savings kept growing. Contest winners increasingly achieved the economic gains through process redesign to improve production yield and capacity. By 1988, these productivity gains exceeded the energy and cheap cialis online online environmental gains. The average return to the 1989 contest was the highest ever, an astounding 470% in 1989, 64 projects costing $7.5 million saved the company $37 million a year — a payback of 11 weeks.

I was a machinist all my working life. Before rapid traverse and power boost selling points were added to machines all the old machines were equipped with counterbalanceing devices. Very cumbersome. Now that those devices use expensive energy wise to follow link womans levitra use we may see a whole lota reinventin' goin' on.
The system is a good investment, it pays for itself

Why even ask for government money? You'd think the ports will jump on the idea and order enough units to upgrade all their cranes ASAP. With such a short payoff time, it's a great investment for the ports, it's a no-brainer!
