The idea is to have solar powered blimps that distrubute wifi and filter the air .



A solar powered blimp would filter the air while distributing free wifi. The blimp could be paid by advertisers. People look up to see  and get a advertisement and see the wifi password.The blimp would clean the air as well by flying.

Category of the action

Building efficiency: Physical Action

What actions do you propose?

I think giving tax credits to companies that help filter the air from emissions as well as credits for planting multiple tress would be a good incentive.

Who will take these actions?

The government as well as corporations and citizens would have to pitch in.

Where will these actions be taken?


How much will emissions be reduced or sequestered vs. business as usual levels?

reducing the air emissions in given cities by up to 4 percent  would be feasible

What are other key benefits?

 monetizing being green

What are the proposal’s costs?

encouraging people to profit from helping the environment might discourage people from volunteering

Time line

over the next 100 years we could encourage business to build models around filtering city air for profit
