The last-mile mobile health services provider, DocGo, has announced the delivery of its new all-electric, zero-emissions ambulance that eliminates the pollution of a standard gasoline ambulance.

The all–electric vehicle will be the first of its kind to be registered in the U.S. The new vehicle has been developed in partnership with Leader Emergency Vehicles in South El Monte, CA, and marks the first step towards “Zero Emission,” the company’s latest sustainability mission to have an all-electric fleet by 2032.

DocGo stated that its new vehicle produces 1/10th of the pollutants expelled by a standard gas-powered ambulance. In addition to being less harmful to the planet, the electric ambulance has the potential to lower patient transportation costs due to lower fuel costs and maintenance needs.

Abundant fuel cell raw materials and renewables potential could add up to a green hydrogen economy in the Philippines, according to Jose Mari Angelo Abeleda Jr and Richard Espiritu, two professors at the University of the Philippines Diliman. In a paper published in this month’s Energy Policy, they explained the country is a latecomer to the sector and should develop basic and applied knowledge for training and research. The country should also establish stronger links between industry and academia, the report’s authors suggested. “The establishment of the Philippine Energy Research and Policy Institute (Perpi) is a move towards the right direction as it will be instrumental in crafting policies and pushing for activities that will usher for more private-academ[ic] partnerships for the development of fuel cell technology in the Philippines,” the scholars wrote. “However, through enabling legislation, a separate and dedicated Hydrogen Research and Development Center (HRDC) will be pivotal in ensuring that sufficient government and private funding are provided.” The authors reported progress in the production of fuel cell membranes but few developments towards large scale production, transport, and storage facilities. “The consolidation of existing renewable energy sources for hydrogen production can also be explored in order to ensure reliable and sustainable hydrogen fuel supply,” they wrote. “This is because the country will gain more benefit if it focuses more on the application of fuel cell technology on rural electrification via renewa[ble] energy-based distributed power generation, rather than on transportation such as fuel cell vehicles.”

Paris-based energy engineering company Technip Energies and Indian energy business Greenko ZeroC Private have signed a memorandum of understanding (MOU) to explore green hydrogen project development opportunities in the refining, petrochemicals, fertilizer, chemical, and power plant sectors in India. “The MOU aims to facilitate active engagement between the teams of Technip Energies in India and Greenko to step up collaborative opportunities on a build-own-operate (BOO) model – in which Greenko will be the BOO operator and owner of the asset and Technip Energies will support with engineering services, integration and EP/EPC [engineering and procurement/engineering, procurement and constructrion] – for pilot and commercial scale green hydrogen and related projects in India in order to offer economically feasible technology solutions to clients,” the French company wrote today.

SSTI and the UW–Madison-based Mayors Innovation Project recently released a new report arguing for a different approach that incentivizes diverse ways to travel to and from new developments. By funding public transportation, limiting parking and preserving the walkability of neighborhoods, Sundquist’s team argues, cities and states can reduce congestion better than if they only plan for cars.

The same solutions can help cities meet their policy goals, such as reduced emissions or more equitable access to services for residents.

“We look at the gap between policy goals on the one hand and the way decisions are being made that actually make things happen in the real world,” says Sundquist. “Often you have great policy goals, and then you have a bunch of rules of thumb that are still basically what was set in the ’50s during the interstate era.”

Researchers at Duke University have demonstrated the first attack strategy that can fool industry-standard autonomous vehicle sensors into believing nearby objects are closer (or further) than they appear without being detected.

The research suggests that adding optical 3D capabilities or the ability to share data with nearby cars may be necessary to fully protect from attacks.

The results will be presented Aug. 10–12 at the 2022 USENIX Security Symposium, a top venue in the field.

The plan is there is no plan.

So it turns out we may be America’s worst-designed city. Lack of “official” zoning. Messy roads and meager public transportation options. Complete chaos. We get it, our predecessors sucked at design. But that may not necessarily be a bad thing. In fact, there are a bunch of ways in which the city totally (and unintentionally) came out ahead in the whole “the plan is there is no plan” deal.

Love it or hate it, Houston’s lack of zoning may actually be what shielded it from the popped housing bubble that rocked the rest of the country. Picture Margot Robbie explaining this all whilst in a bubble bath drinking champagne. While housing prices soared as the national bubble inflated, Houston’s costs remained modest; and when all hell broke loose when the bubble burst, H-town remained largely unaffected.

As discussed in an article from the Chron, senior economist Bill Gilmer found that zoning regulations were partly to blame. First, the laws constricted supply, which resulted in raising the cost of new home construction. As housing demand increased, cities with strict zoning laws saw prices increase due to the lack of supply. In turn, the high housing prices extinguished demand and — BOOM — the mortgage market collapsed and chaos consumed the majority of the country — minus Houston, where the increase in demand was met with an increase in construction/supply. Or something like that. Whatever. Margot Robbie in a bubble bath.

Dubbed Infinity Train, it works by using gravitational energy created on the downhill sections of the rail network to recharge its battery power and eliminate the need for recharging on the return leg of the journey.

The train will allow for a capital-efficient solution for removing diesel and pollutants from Fortescue’s rail operations. It will also help remove the need for the generation of renewable energy as well as the setting up of expensive charging infrastructure.

Researchers at Johns Hopkins University have developed a new shock-absorbing material that is super lightweight, yet offers the protection of metal. The stuff could make for helmets, armor and vehicle parts that are lighter, stronger and, importantly, reusable.

The key to the new material is what are known as liquid crystal elastomers (LCEs). These are networks of elastic polymers in a liquid crystalline phase that give them a useful combination of elasticity and stability. LCEs are normally used to make actuators and artificial muscles for robotics, but for the new study the researchers investigated the material’s ability to absorb energy.

The team created materials that consisted of tilted beams of LCE, sandwiched between stiff supporting structures. This basic unit was repeated over the material in multiple layers, so that they would buckle at different rates on impact, dissipating the energy effectively.
