Most regular fliers have at least one horror story of marathon delays at the airport. What they may not know: airlines will cough up as much as $800 in compensation if a flight is delayed more than three hours.

But this process requires multiple phone calls, paperwork and other red tape that can take a huge investment of time. AirHelp will take care of that process for you. Tell them your flight number and the company takes care of the rest.

In exchange, they get 25% of what the airline pays you, if the claim is successful. And the airlines have an extra incentive to fly on time whenever they can.

Batteries that not only don’t degrade but have their capacity increased by as much as 40%-- that’s what BatteryOS is promising with its battery management system.

This startup has fixed that problem by changing the way energy inside existing batteries is controlled. Meaning that batteries can be charged to previously unreachable capacities, while preventing degradation.
